11. What are the types of reports that we have in Salesforce? 

There are four types of reports available in Salesforce:

• The tabular report is the one that shows the total.
• Matrix reports are formatted so that columns and rows group.
• The summary report provides detailed reports by column.
• Joined reports, which are capable of allowing two or more reports in one report.

12. What is an Audit trail? 

The Audit trail in Salesforce is a unique feature that helps you and other administrators track changes made across the organization. It would be helpful for an organization with more administrators. This audit trail shows information about the 20 most recent changes in your organization.

Below are the things that you could come to know: 

• The date and time. 
• Username of the person who made the changes
• What the change was. 

13. What are the benefits of using Salesforce CRM?

 We get the following benefits by using Salesforce CRM.   

• Improved organizational understanding.
• Enhanced communication.
• We can better understand the customer and provide better services.
• Salesforce automates repeated rule-based tasks.
• Improved analytics and dashboards to analyze the data.
• Reduction in cost and cycle time.
• Improves the efficiency of teams.

14. What is a profile? Can two users have the same profile?

A profile is a collection of rules and procedures a person must follow to access particular records. There are multiple profiles available in Salesforce. For example, a sales profile can access leads, opportunities, contacts, campaigns, and more.

As for the second question, the answer is yes. The people who work in one department have the same profile. So the people who work under a particular department would be assigned the same profiles.

As we have seen in the sales profile, many people work under it, and each person assigned to it has the same profile. Hence, any number of people can have the same profile.

15. Explain the difference between role and profile.

Role: In Salesforce, a role increases a user's data visibility. It can be done by sharing rules or by building a role hierarchy. Using roles, you can control access.

Profile: Unlike roles, the profile is mandatory for all and remains at the object level. It is treated as a building pillar of an organization.

16. How many relationships do we have in Salesforce?

We have three types of relationships in Salesforce, which are:

• Master-detail relationship
• Lookup relationship
• External Lookup

17. What is the Master-Detail relationship?

This Master-Detail relationship is the same as the relationship between a parent & child. In this context, the Master is treated as the parent, and the Detail as the child. The master Object controls the behavior of the Detail object. 

The child's survival depends on the parent because if the Master is deleted, the Detail will also be automatically deleted. You can create Roll-up summary fields in master records to calculate the Min, Avg, and Sum of the child records.

18. What is a “Lookup Relationship”?

The relationship between the two objects is called a lookup relationship. Lookup relationships connect two objects so you can look up related items from other items. It can be one-to-one or one-to-many.

19. What is an External lookup?

The external lookup relationship connects the child object to the parent object. The child object may be either a custom, standard, or external object. It is used to identify the correct map of the child object with the parent external object. The external lookup relationship field values are matched against the External ID values.

20. What is a self-relationship?

It is a personal lookup to the same object. The self-relationship creates a tree diagram of the objects. 

Let's take an example of an object, “merchandise.”In this, we can create a merchandise relationship between two accounts.s. This is called a self-relationship.

21. What is the workflow in Salesforce?  

 Workflow is an excellent way to automate specific business processes in Salesforce. To do this, you are required to define certain rules and regulations to automate tasks such as sending an email, updating a field, and create a task.

• We can have access to workflow across the object.
• It is not possible to query from the database.

22. What is meant by “Transfer record” in the profile? 

A transfer record is a type of function used to grant permission. If a user has permission to share a record with others, they can share the record with read-only access.

23. Explain the Salesforce dashboard.

In Salesforce, we use dashboards to represent the data in a pictorial format. The Salesforce dashboard is capable of displaying 20 reports at a time.

24. What is SOAP?

A protocol that defines a uniform way of passing XML-encoded data. SOAP Stands for Simple Object Access Protocol.

25. What is a Time Trigger?

The computer system executes one or more tasks according to the set of rules and scheduled tasks.

26. What is Trigger in Salesforce?  

A trigger is Apex code that executes before or after the insert, update, or delete statements. A trigger enables you to perform custom actions before and after modifications to Salesforce records.

For more details, visit - Trigger Scenarios in Salesforce

27. What are the actions in the workflow? 

The actions listed below are part of the workflow.

• Field update 
• Task
• Outbound message 
• Email alert 

28. What are the main things that need to be considered in the “Master-Detail Relationship”?

The parent determines record-level access; mandatory on the child for the parent's reference; cascade delete (if you delete the parent, it can cascade delete the child).

Salesforce Intermediate Interview Questions

 Yes, it is possible in a master-detail relationship.

31. How many Master-detail relationship fields can be created in an object?

A maximum of two MDR fields can be created in an object.

32. How many LR (Lookup Relationship) fields can be created in an object?

A maximum of 40 Lookup relationship fields can be created in an object.

33. If we delete parent records in MDR, what happens to the child?

If you delete the parent record in the MDR, the child record is also deleted.

34. What about the undelete option?

It will restore the record with the data in the object.

35. How many Roll-Up Summary fields can be created in an Object?

In Salesforce, you can create up upto 25 roll-up summary fields per object by default.

36. If we reparent in the object, will the parent update?

Yes, the parent will update the object.

37. How can we create an MDR on those objects where we already have records?

1. First, we create LR between the two objects.
2. Connect all child records to parents.
3. Convert the field type from LR to MDR.

38. How to look at the user license information in Salesforce Org?

Steps to find out the user's license:

Salesforce Org → Setup → Administer → Company Profile → Company Information.

39. Can we delete a user in Salesforce?

No, we cannot delete the user in Salesforce. 

40. Can we change the license when we create a profile?

No, we cannot change the license during profile creation. 

41. Explain the object relationship overview.

It creates a link between the custom object and the standard object recorded in a related list. This is helpful to find the product's defects.

42. How to create many-to-many relationships in Salesforce?

It helps in creating a many-to-many relationship between two objects in Salesforce. Using many-to-many relationships, we can connect each record of an object to multiple records of other objects, and vice versa. The junction object helps us connect the two selected objects.

43. What are the permission sets? 

A permission set is a collection of settings and permissions that extends a user's functional access without changing the user's profile. You can use permission sets to extend access to functionality for various user types, regardless of their roles. 

It is a time-consuming task to create a profile; instead, you could easily create a permission set as a sharing rule. If we want to give access to other users, we use sharing rules.

44. What are the default indexed fields in Salesforce? 

We have some fields that are indexed by default in Salesforce, which are:

• Name 
• ID 
• Owner fields 
• Master-detail relationship fields 
• Lookup fields 
• Last modified dates 
• Audit dates

45. What is the Fiscal year in Salesforce?

 The Fiscal year refers to the start and end dates of a company's financial year. We have two types of financial years in Salesforce:

1. Standard fiscal year 
2. Custom fiscal year

46. List some examples of custom fields?

There are many custom fields available, such as Picklist, Currency, Date, Text, Picklist (multi-select), Email, Percent, Number, Phone, Text area, Lookup relationship, Geolocation, Checkbox, Master-Detail relationship, etc.

47. What are the different ways to store various types of records in Salesforce? 

We have five different ways in Salesforce to store various types of records, such as images, files, and documents. 

They are:

• Attachments 
• Google drive 
• Chatter Files 
• Libraries 
• Attachments.

48. What is the main difference between data table and page block table tags?

The differences between the Data table and Page block

Page block:

It is defined inside the page block section or page block. To design visual pages using style sheets, the required attribute is “value.” It will automatically display Column Headers.

DataTable:

• No need to mention inside the page block station or page block
• No required value.
• The data will be displayed using custom style sheets.
• We need to specify column headers explicitly.

49. What can cause data loss in Salesforce? 

Many things can contribute to data loss in Salesforce. Which includes :

• Migrating to numbers, percentages, and money from other data types.
• When you change the date and time
• Migrating to a multi-select picklist from any type except a picklist.
• Moving from a checkbox, auto number, or multi-select picklist to any other type.
• Changing text area to phone, URL, email, or text.

50. What is the junction object, and what is it used for? 

Junction objects are mainly used to create a many-to-many relationship in Salesforce. If you consider a recruiting application as an example, you can find a position that is linked to many candidates. Similarly, a candidate can apply for multiple positions. 

51. How does Salesforce track sales details?  

Salesforce gives accurate results for the following things:

• Number of customers served daily.
• Regular sales numbers
• Complete reports from the Sales Manager.
• Generates sales reports on a timely basis
• It provides the details of repeat customer activity.

52. Is it possible to restrict access to data using sharing rules?

Sharing rules are used only to allow greater access to records, not to restrict.

53. Can we schedule a dynamic dashboard in Salesforce? 

No, we can not do that in Salesforce.

54. How many ways can we share a record?

Role Hierarchy :

If we add a user to a role, the user above them in the role hierarchy will have read access.

Setup → manage users → roles → setup roles → click on ‘add role’ → provide name and save.

OWD:

• Defines the baseline setting for the organization.
• Defines the level of access the user has to view the other user’s record.
• OWD can be Private, Public Read Only, or Public Read and Write.

Setup → Security Controls → sharing settings → Click on ‘Edit’

Manual Sharing :

Manual Sharing is the process of sharing a single record with a single user or a group of users.

We can see this button on the record's detail page, but it is visible only when the OWD setting is set to Private.

55. What is the difference between insert() and database .insert()?

Using the insert method, we can insert records, but if an error occurs in any record, the system will throw an error: "insertion failed," and none of the records are inserted. To execute a successful bulk insert operation, we will use the database method.

56. Can you create and insert their custom logo when creating their custom applications?

Yes, users can upload their custom logo in documents, and then they choose that logo for the organization.

57. List things that can be customized on-page?

We can customize various elements on page layouts, such as Fields, Buttons, Custom Links, and Related Lists. We can also create sections.

58. Can we create a Roll-Up Summary (RUS) field on the master object?

Yes. We can create a Roll-Up Summary field on the master object.

59. Can the governor limit the performance of partial DML activity? Eg: we are inserting 200 records in a loop; the Governor limit is hit at the 151st record, then will those 150 records be created?

No, either all or none.

Salesforce Apex Beginner Interview Questions

60. What is Apex Interface?

The interface is a collection of unimplemented methods. This will specify the method's signature, the input types we pass to the method, and the output type.

Generally, the interface methods are defined as global.

61. Where can you use Apex?

We can use Apex in the following ways

• To create Email services
• Create web services
• Perform complex validation over multiple objects
• To create complex business processes that are not supported by a workflow.
• Create custom transaction logic
• Attach custom logic to another operation

62. How Does Apex Work?

All Apex programs run on-demand entirely on the Force.com Platform.

• First, the platform application server compiles the code into an abstract set of instructions that the Apex runtime interpreters can understand.
• The compiled code is stored in metadata.

When end users trigger the execution of Apex by clicking a button or the Visualforce page, the application servers retrieve the compiled instructions from the metadata and send them to the runtime interpreter before returning the result.

63. What is Apex in Salesforce?

Apex is a strongly typed object-oriented programming language.

It allows the developer to execute flows and transaction control statements.

Apex enables developers to add business logic to most system events like button clicks related to record updates and VisualForce pages.

64. What are the ways to call the Apex class? 

Below are the ways to call an Apex class in Salesforce.

• From another class 
• From developer console 
• From JavaScript links
• From home page components   
• By using trigger 
• From VisualForce page.

65. Explain various methods of the batch Apex class?

The batch Apex class implements the Database. Batchable interface with the three methods as follows:

Start: We use the start method at the beginning of the batch Apex job. We use it to collect objects or records and pass them to the interface for execution. It returns a DatabaseQueryLocator object that comprises the objects or records sent to the job.

Finish: We call this method once the batch processing is complete. We use this method to send confirmation emails or to execute the post-processing operations.

Execute: We use this method for every batch of records sent to it. We use this method for data processing. This method does the following:

• sObjects records list
• Reference to the DatabaseBatchable context.

66. What is Apex Email Service?

Email services are automated processes that use Apex classes to process the contents, Headers, and attachments of inbound email.

• Visualforce email templates cannot be used for mass emails.
• We can associate each email service with one or more salesforce-generated email addresses to which the users can send messages for processing.

67. Explain the Apex Programming Language?

• Integrated: It provides built-in support for DML Calls
• Inline Salesforce Object Query Language
• Easy to Use
• Easy to Test
• Version
• Multi-Tenant Aware Application.

68. What is Map Class in Apex Salesforce?

Map Class in Apex:

• Map Class Contains methods for the Map collection type.
• A Map is a collection of key-value pairs where each unique keymap to a single value.
• Map keys and values can be any data type primitive types, collections, objects, user-defined types, and built-in Apex types.

For Example, the following table represents a map of countries and currencies

Country(Key)	‘United States	‘Japan’	France’	‘England’	‘India’
Currency (Value)	‘Dollar’	Yen’	‘Euro’	‘Pound’	‘Rupee’

69. What is Batch Apex in Salesforce?

Batch Apex allows you to define a single job that can be broken up into manageable chunks, whereas every chunk can be processed separately.

In the Batch Apex it will fetch all the records on which you want to perform the field update and divide them into a list of 200 records and on every 200 records operation is performed separately.

This would help us to execute on more than 10,000 records as it won’t perform an operation on all the records in a single transaction instead it divides them into a number of subtasks where each subtask may contain records up to 4000.

Example:

If you need to update every record of the Account object in your organization, we have governing limits that would prevent us from achieving this task.

Reason: In a single transaction, we can process only 10,000 records. Now, in the above case, if the organization has more than 10,000 records, we cannot perform this field update.

Salesforce Apex Intermediate Interview Questions

70. What is Apex Scheduler?

It will invoke the Apex classes to run at a specific time.

Anybody who wants to schedule their class they have to implement the schedulable interface.

Schedule Interface: The class that implements this interface can be scheduled to run at different intervals. This interface has several methods that are

Public void execute(schedulablecontext sc)
Public class mySchedule implements schedulable
{
Public void execute(schedulablecontext sc)
{
Account a = new Account(Name = ‘Faraz’)
Insert a;
}
}

71. What is the Apex Trigger in Salesforce?

The trigger is an Apex Code that executes before or after. The following types of DML Operations:

• Insert
• Update
• Delete
• Merge
• Upsert
• Undelete

72. What is meant by Apex transaction?

An Apex transaction represents a group of operations that must be executed together. It includes the Data Manipulation Language (DML) and is used to query records. The DML operations in a transaction either succeed or, if anything goes wrong or occurs even with a single record, could result in a rollback of the entire transaction.

73. What are the types of Apex Triggers in Salesforce?

Triggers are divided into 2 types:

1. Before Triggers
2. After Triggers

Before Triggers can be used to update or validate values of a record before they are saved to the database.

After Triggers Before Triggers can be used to access field values of the records that are stored in the database and use this value to make changes in other records.

Syntax:

Trigger trigger_name on Object_Name(trigger_events) { Code_block } WHERE trigger_events can be comma separated list of events.

74. What is Apex Managed Sharing?

Apex Managed Sharing enables developers to support an application in sharing requirements.

• This type of sharing is available only to users to modify all data permissions. Only these users can add to or change Apex-managed sharing.
• Apex Managed Sharing uses a Sharing reason (Apex Sharing Reason).

75. What is the Usage of the apex program within the VisualForce page?

When you want to call the Apex class on the Visualforce page, you have to declare it in the following format.

< Apex : page controller = “class name “ >

Whenever we call a Visualforce page whose controller attribute is defined, it first creates an object for the Apex class defined in the controller. When an object is created for an Apex class, the constructor is invoked first.

76. What is Sandbox in Salesforce?  

A Sandbox is a testing environment used to test code or conduct experiments in isolation without affecting the production environment.

77. When do we use Sandbox?

A Sandbox helps you test a newly developed application on a Visualforce page. It is not possible to check anything in the production environment; doing so disrupts normal operation. So, to get out of this problem, developers use a sandbox to test the application.

Types of sandboxes available are :

• Developer
• Developer pro
• Partial copy
• Full

Salesforce Apex Advanced Interview Questions

78. What is Multitenant Architecture in Salesforce?

It is the cloud's fundamental technology for securely and cost-efficiently sharing IT resources.

Static resources allow you to add content you want to reference on the Visualforce page, including images, JavaScript files, archives, and CSS files. The maximum size of a static resource for an organization is 250 MB.

80. List the data types that a Set can store.

The Sets can store any of the following data types

• Collections 
• User-defined types
• subjects 
• Primitive types
• Built-in Apex types

81. What is a Visualforce component? 

Visualforce components are small, reusable units of functionality, such as widgets, user interface elements, and panels. We have two types of VisualForce components: standard and custom, which define user interface behavior.

82. What is SOQL?

A query language that allows you to construct simple but powerful query strings and to specify the criteria that should be used to select the data from the platform database.SOQL Stands for Salesforce Object Query Language.

83. What is the Bulkification best practice?

We must avoid using index values like Trigger.New[0] as we never know how many records we get in Trigger.New at runtime.

1. We need to use it for each loop whether we have 1 record or many.
2. We must not use SOQL inside for loop.
3. We must not use SOSL inside for loop.
4. We must not use DML inside for loop.
5. We need to store data in collections so our code will work with both single and multiple records.

Salesforce Apex Technical Interview Questions

84. How can you perform DML partially?

If we want partial DML to happen, use a database.insert(list, false);

85. What Are The Types of SOQL Statements in Salesforce?

Salesforce Object Query Language is used to query records in the database.com based on requirements.

There are 2 types of SOQL Statements:

1. Static SOQL
2. Dynamic SOQL

Static SOQL: 

The Static SOQL Statement is written in [ ]  (Array Brackets)

These statements are similar to IINQ (Ion Integrated Query)

Example:

String search for =’Jones’;
Contact[] contacts=[select testfield__c, FirstName, LastName from Contact Where Last Name=:search for];

Dynamic SOQL:

It refers to creating an SOQL string at runtime using Apex code.

• Dynamic SOQL enables you to create a more flexible application.
• To create a Dynamic SOQL query at run time use a Database.Query() method, in one of the following ways.
• Return a single sObject when the query returns a single record.
• sObjects s = Database. Query(String_limit_l);
• Return a list of sObjects when the query returns more than a single record.

Example 1:- Queries

String myTestString = ‘TestName’;
List List= Database.Query(SELECT Id FROM MyCustomObject__c WHERE Name = :myTestString);

Example 2:- Queries

String resolvedfield L = myvariable.field__c;
List L = Database.Query(‘SELECT Id FROM myCustomObject__c WHERE field__c = ‘+resolvedfield_L);

86. What is the Syntax of SOQL Statement?

Syntax -

SELECT field1, field2,.... FROM Object_Type [WHERE condition]

Example:-Queries

List accountList =  [SELECT ID, Name, FROM Account];
List accountList = [SELECT ID, Name, FROM Account WHERE annual revenue<10000];

87. Explain briefly about GROUP BY with the syntax?

With API version 18.0 and later/you can use GROUP BY with aggregate functions, such as SUM() or MAX(), to summarise the data and roll up query results rather than processing individual records in your code.

Syntax: [ GROUP BY field GROUP BY LIST]

88. SOSL Statements In Salesforce Apex.

The SOSL statement evaluates the list of sObjects, with each list containing the search results for a particular sObject type. The result lists are always returned in the same order as they were specified in the query.

If an SOSL query does not return any records for a specified sObject type, the search results include an empty list for that sObject.

Example: You can return a list of accounts, contacts, opportunities, and leads that begin with the phase map.

List < list < subject >> search list = [ find 'map*' In ALL FIELDS RETURNING Account (ID, Name), contact, opportunity, lead ];

Note:

• The syntax of the class in Apex differs from that of the FIND clause in the SOAP API.
• In Apex, the value of the FIND clause is demarcated with single quotes.

Example:

FIND 'map*' IN ALL FIELDS RETURNING account (Id, Name], Contact, Opportunity, Lead. In the Force.com API, the value of the FIND Clause is demarcated with braces.

FIND {map*} IN ALL FIELDS RETURNING account  [Id,name], contact ,opportunity,lead;
From search list , you can create arrays for each object returned.
Account [ ]  accounts = (( list < accounts > ) search list [0] );
Contact [ ]  contacts = [( list ) search list [0]) ;
Opportunity [ ] opportunities = ((list < opportunity> ) search list [2]) ;
Lead [ ] leads = (( list < lead> ) search list [3]);

89. Explain JavaScript remoting for apex controllers?

We can use JavaScript remoting in Visualforce to call methods in Apex controllers from JavaScript.

JavaScript remoting has 3 parts.

• The remote method invocation you add to the Visualforce page is written in JavaScript.
• The remote method definition is in your Apex controller class.
• This method definition is written in Apex, but there are a few differences from normal action methods.
• The response handles the callback function you add to or include in your VF page, written in JavaScript.

90. How to add JavaScript remoting to a Visualforce page?

To use JavaScript remoting in a Visualforce page, add the request as a JavaScript invocation with the following form:

Syntax -

 [namespace.] controller.method ( [parameters ...] Call back Function, [configuration] );

91. Give your thoughts on Configuring JavaScript remoting requests?

JavaScript remoting supports the following configuration parameters.

Name	Datatype	Description
Buffer	Boolean	Whether to group requests executed close to each other in time into a single request. The default is true.
Escap	Boolean	Whether to escape the apex methods response. The default is true.
Timeout	Integer	The timeout for the Static Resource request in milliSeconds. Default is 30000(30 seconds)

92. What is a Declarative Approach?

It is about working on a project without code.

93. What is the Customization / non-declarative approach?

It is about working on a project with code.

94. If one wants to actually compare the variable name in a query, what operator should be used?

=: is the operator used to compare.

95. When one wants to pass the collection to the query instead of passing one value, which keyword helps us?

IN - keyword.

96. What two benefits do you get by writing controllers?

We get Logic & Data.

97. How to call JavaScript in a VisualForce page?

Add a JavaScript file in Static Resource setup -> develop -> Static Resources -> click on ‘New’ -> Name: filename and add file from local desktop and save.

98. What are the differences between SOQL and SOSL in Salesforce?

SOQL - (Salesforce Object Query Language)	SOSL (Salesforce Object Search Language)
Using SOQL we can Search only on one object at a time.	Using SOSL, we can search across many objects at once.
We can query on all fields of any datatype	We can query only fields with data types text, phone, and Email.
We can use SOQL in the Triggers and the classes.	We cannot use Triggers, but can in classes.
We can perform a DML operation on the results of an SQL query.	We cannot perform DML operations on search results.

99. What is Future Annotation(@Future)?

We can use the future annotation to indicate that these methods execute asynchronously.

• Methods with future annotation must be static methods
• Methods with future annotations can only return void.

Syntax:

global class class_name
{
@future
Static void methodname(parameters)
 {
//body of the method
}
}

100. What is the AppExchange directory?

A web directory where hundreds of app exchange apps are available to Salesforce customers to review, demo, comment upon, and /or install. Developers can submit their apps for listing on the appexchange directory if they want to share them with the community.

101. Which tag is used with both radio buttons and picklists to create the selectable values?

We use <Apex:selectoption>

102. Which field cannot be added to a custom index?

We cannot add formula fields to the custom index in Salesforce.

103. What is the difference between a trigger and a workflow?

Workflow:

• Workflow is an automated process that fired an action based on Evaluation criteria and rule criteria.
• We can access a workflow across the object.
• We cannot perform DML operations on a workflow
• We cannot query the database

Trigger:

• A trigger is a piece of code that executes before or after a record is inserted or updated.
• We can access the trigger across the object and relate it to that object
• We can use 20 DML operations in a single trigger.
• We can use 20 SOQL from the database in a single trigger.

104. What are some Apex classes that are commonly used within?

Standard controller, select option, page reference, message, etc.

105. What are the effects of using the transient keyword?

The transient keyword prevents the data from being saved in the view state. This should be used for very temporary variables.

106. What is the maximum number of field dependencies we can use in the VisualForce page? 

The maximum number of field dependencies we can use on a Visualforce page is 10.

107. What is the procedure to get the Security token in Salesforce?       

Click on your Name tab, then click on Personal, and you will find Reset my security token."

108. What is a Metadata-driven development model?

 An app development model that allows apps to be defined as declarative “blueprints,” With no code required. Data model, objects, forms, workflows, and more are defined by metadata.

109. What is S-Control?

S-Controls are the predominant Salesforce.com widgets, built entirely in JavaScript. These are hosted by Salesforce but executed on the client-side. S-Controls are superseded by Visualforce now.

110. What is a wrapper class in Salesforce?  

A wrapper or container is a data structure, a class type, or an abstract data type that contains multiple collections of objects. It helps in displaying various objects on a VisualForce page in a single table.

111. What are Force.com platform sites?

Public websites and applications that are directly integrated with your Salesforce organization without requiring users to log in with a username and password.

112. What is a Tab in Salesforce?

A Tab is a user interface to display custom object data or other embedded web content to a user. We have three types of tabs in Salesforce, which are:

• Custom Tabs.
• Visualforce Tabs.
• Web Tabs.

113. What are the types of email templates that can be created in Salesforce?

Below is the list of templates available in Salesforce:

1. Text Template: This template can be modified or changed by any user.
2. HTML with letterhead: People like administrators and users with Edit HTML permission can create this email template based on the letterhead
3. Custom HTML: Administrators and users can edit the HTML permission to create this email template without using letterhead. It requires knowledge of HTML or the HTML code to insert it into the email template.
4. Visualforce Email Template: This template can only be created by Visualforce administrators and developers. It can merge data from various records.

114. Suppose we want to share records based on conditions, such as sharing records with a group of users. Whose country criteria are India? What are the steps to be followed?

Setup → Security Controls → sharing settings → Click on ‘Edit’

Apex sharing: The Share object is available for every object (for the Account object, it is AccountShare). If we want to share the records using Apex, we have to create a record in the shared object.

115. Is it possible to edit the VisualForce page in a production environment?

Yes, we can create and edit the Visualforce pages in both the production environment and in a sandbox. The only thing you can not do in a production environment with a Visualforce page is add unique values, for which you need to do this in the sandbox.

116. Is it possible to make changes to the apex trigger/apex class in the production function?

No, you can not do that. If you want to make any edits to the Apex trigger/Apex class, that should be done in a sandbox environment.

117. What are the things that can be customized on page layouts?

Page layouts allow you to personalize or customize the given page objects or records. It helps customize or design the page according to your requirements. The page layout editor helps you customize pages. On this page, you can customize elements such as buttons, fields, custom links, and related lists.

118. How to invoke batch apex job (or) how to execute the batch apex job programmatically?

We can use the Database. The executeBatch() method is used to start the batch job programmatically.

Syntax:

1. Public static ID execute batch ( sObject class name)
2. Public static ID execute batch (sObject class name, integers scope)
3. The above two methods are static methods of the database class. We can use any one of the methods to execute the batch job.

The class name that we are passing to the database. The executeBatch() method should be the method of the class that implements the database—batchable interface.

119. Will Visualforce still support the usage of merge fields like S-control?

Yes. Just like S-Controls. Visualforce pages support embedded merge fields.

Salesforce Admin Interview Questions

Let’s read through some Salesforce administrator interview questions and answers in this section

120. What is the Roll-up summary field?

We use the Roll-up summary field to calculate values for associated records, such as those in a related list. We can also use it to create values for a master record based on the values in the detailed records. But we must connect the master and the detail with a master-detail relationship.

121. Explain Queues.

In Salesforce, Queues help us distribute, prioritize, and assign records to teams to share workloads. Queues apply to leads, service contracts, custom objects, cases, and more.

122. Explain Escalation rules.

Escalation rules apply to escalation cases according to the rules specified in the escalation rule entry. In addition to rule entries, we can create escalation actions to determine what happens when a case escalates. The escalation rule can reassign a case to another support agent or a support queue. 

123. Explain Validation rules.

Validation Rules enable us to apply specific logic to contribute to our organization’s data integrity. We can define conditions on the object that are not available. For instance, we do not want to label an opportunity as closed if the account does not have an address.

124. What are the primary components of the workflow?

The following are the primary components of the workflow:

Criteria: Criteria is the “if” portion of the statement. We have to set criteria for the workflow rule. First, we have to create a workflow rule, then configure the criteria.

Action: Action is the “then” portion of the statement. The action tells us what to do when the criteria are satisfied and occurs after the workflow rule configuration. We can add a time-dependent or immediate action to a particular workflow rule.

125. Explain a Time-dependent workflow.

We perform time-dependent actions at particular times before closing the record. The workflow re-evaluates the record over time. It checks whether the workflow rule criteria are satisfied, and only then does the workflow rule execute the actions.

126. What are the Workflow Task and Workflow Alert?

Workflow Task

When we have to assign tasks to a Salesforce user, we create a workflow task. A workflow task allocates a new task to a role, user, or record owner. It helps us define task parameters such as priority, status, due date, and subject.

Workflow Alert

A workflow alert is an email that an approval process or a workflow rule creates in Salesforce and is transmitted to different recipients.

127. Explain Auto-Response.

Auto-Response is about sending emails to leads or cases based on specific record attributes and promptly responding to customer inquiries or issues by setting up the auto-response rule. At the same time, we can set one rule for leads and another for cases.

128. Explain Custom Labels?

In Salesforce, we use custom labels for creating a multilingual application. Using the native language, they give information to users in the form of help texts and error messages. 

We can define the custom labels as custom text values that we can access from the Apex class, Lightning components, and even the Visualforce page. We can translate these values into Salesforce-supported language. Through the following path, we can access custom labels:

Setup->Search Custom Labels in Quick Find Box->Custom Labels 

129. What are sharing rules, and what are the different types of sharing rules?

Sharing rules grant access to users associated with public groups, roles, or territories. It provides a higher level of access with exceptions, which is far from our organization's settings. The following are the two kinds of sharing rules:

• Criteria-based Sharing rules: Access is granted based on record values, not on record owners.
• Owner-based Sharing Rule: This rule provides access to records owned by users.

129. What are Governor Limits?

To ensure that no one gains access to others' resources, Force.com imposes various restrictions (governor limits) on code execution. Salesforce must do this due to its multi-tenant architecture, in which all customers and organizations share a single resource. If the governor's limits are exceeded, an error will occur, and the program will terminate.

The following are the types of Governor limits:

• Static Apex Limits
• Per-transaction Apex Limits
• Size-specific Apex Limit
• Per-transaction Certified Managed Package Limits.

130. Define the Approval process.

In Salesforce, the Approval process is a sequence of steps used to approve records. An approval process is also helpful for tracking who approved or rejected something, and when. It includes different approval models, notifying approvers, and conditional logic for who must approve.

131. What is the importance of Salesforce Chatter?

Salesforce Chatter is a social networking application that enables us to share information and collaborate. It helps us to build greater employee engagement through motivation. Salesforce Chatter also provides a forum throughout the enterprise for sharing fresh ideas and understanding. We can also use the mobile feed for tracking our project.

132. Explain Guest users.

Guest users are users who do not have user accounts in our organization. They are also known as unauthorized users as they do not have to log in. We can make the pages accessible. Unauthorized users can create or edit the records.

Generally, we have various limitations and considerations for assessing. Yet we can use this feature to solve use cases at no additional cost, since guest user licenses are free.

133. Explain Change Set.

A change set is a group of components that we can migrate between associated organizations (e.g., from sandbox to production, sandbox to sandbox, etc.).

Salesforce Developer Interview Questions

Here is a list of the most frequently asked Salesforce Developer interview questions and answers.

134. What is Apex test coverage? 

To ensure that our code meets specific standards, Apex test coverage shows how many lines of code in our classes or triggers have been tested by the test methods. Test coverage percentage is the result of the number of covered lines divided by the sum of uncovered and covered lines. To deploy to production, we need at least 75% test coverage.

135. Explain Lightning Message Service (LMS).

Lightning message service is a distinctive Salesforce feature that enables interaction among Aura, Lightning Web Components, and Visualforce on the same Lightning page. We can use the Lightning message service only in Lightning Experience.

136. Define OAuth.

OAuth is a standard for access delegation. Generally, we use it to grant applications or websites access to data on other websites, without requiring passwords.

137. Explain Connected App.

Connected Apps integrate with Salesforce through APIs and use OAuth and SAML for authentication, sign-on, and token issuance to access the Salesforce APIs.

In addition to OAuth capabilities, connected apps enable Salesforce admins to establish different security policies and provide external control over how similar apps are used.

Architect enterprise-grade custom apps with confidence through our expert-led Salesforce Developer training.

138. What is the Significance of an Outbound Message?

Outbound Message is an automation function that can be triggered from a workflow rule. We can send the message to explicit web services that start other processes in explicit systems.

139. What are the uses of External ID fields?

We can define specific fields as an External ID on the object. We can use these External ID fields to balance data from explicit systems using a distinct reference ID.

For instance, if we need to reconcile data from the explicit accounting system with Salesforce Accounts, we must promptly use an external ID field to reference the accounting system's unique ID in place of the Salesforce ID.

140. How can we create partial page refreshes?

First, we have to define the page section to be refreshed, then the event that triggers the refresh. The method changes if the area being refreshed is similar to the one managing the event. It also depends on whether we are processing on the server or changing the user interface.

141. How can we invoke the JavaScript controller action by using a component markup?

By using the action provider, we can invoke the JavaScript controller action through a component markup.

142. What are component and application events?

Application events

By using any component, we can fire and manage application events. Application events do not require any relationship among components; however, these components should be part of an application.

Component events

Child components fire component events, and Parent components handle them. We use component events to send a value from a child component to a parent component.

143. What is Pagination, and how can you implement it?

For example, if we have to display 100 records on the page.

• First: Display the first ten records.
• Previous: Display the previous ten records.
• Next: Display the following ten records.
• Last: Display the previous ten records.

We can perform the above process through Pagination. We can achieve pagination through the following ways:

• Through StandardSetController
• Through the Offset and Limit keywords in the SOQL Query.

144. How do we display error messages on the Visualforce Page?

To display error messages on the VisualForce Page, we must use:

<apex:pageMessages></apex:pageMessages>

In an Apex class, we must use:

ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.Error, ‘Error Message’));

145. What are the differences between Custom Objects and Custom Settings?

Custom Objects	Custom Settings
Custom Objects store the data in the database.	Custom settings store data in the Application Cache.
Custom objects must use SQL queries to fetch records from the database.	Do not need to use SQL queries to fetch records.
In custom objects, all data types exist.	In Custom settings, only confined data types exist when compared to custom objects
On Custom objects, we can create apex triggers and validation rules.	On List Custom settings, we cannot create Apex triggers and validation rules
We can create a tab for custom objects.	We cannot create a tab for custom settings.

146. Can we customize the Apex in a production organization?

We cannot customize Apex in the production organization. We must change and deploy through a sandbox and satisfy test coverage requirements.

147. Can you give an example of Salesforce API and its importance?

Salesforce has different API’s that allow us to communicate with the system in various ways:

REST API: REST API will enable us to integrate with Salesforce applications via HTTP methods using JSON or XML.

Bulk: The Bulk API provides programmatic access, allowing us to load data into our Salesforce enterprise rapidly.

Streaming: We can use the Streaming API to receive notifications about Salesforce data changes that match the SOQL query we define. The streaming API is functional when we need to push notifications from the server to the client based on the criteria we define.  

148. Explain Bucket Fields.

Bucket Fields classify records in Salesforce reports without any custom fields or formulas; they are available only in reports. When we create a bucket column, we can classify various group report values.

149. Differentiate isNull and isBlack.

We use isBlack() for text fields. Since text fields cannot be NULL, even though nothing is given as a value, the ISNULL() function fetches only empty values. If we use ISNULL() with a text field, then it returns false.

150. How does Salesforce implement Sales Tracking?

Salesforce records data on customer details, sales numbers, customers served, and repeat customers, and uses this data to create detailed charts, dashboards, and reports. In this way, it tracks our organization's sales.  

151. Explain the methods of the Batch Apex Class.

The batch apex class deploys the database batchable interface with the three methods as follows:

Start: We use the start method at the beginning of the Batch Apex job. We use it to collect objects or records and pass them to the interface for execution. It returns a DatabaseQueryLocator object that comprises the objects or the records sent to the job.

Finish: We call this method once the batch processing is complete. We use this method to send confirmation emails or to execute the post-processing operations. 

Execute: We use this method for every batch of records sent to it. We use this method for data processing. This method does the following:

• sObjects records list
• Reference to the DatabaseBatchable context.

152. What are the different types of Bindings?

The following are the different types of bindings:

• Action Bindings: Action Bindings refer to action methods in the controller.
• Data Bindings: Data Bindings refer to the data sets in the controller.
• Component Bindings: They refer to Visualforce components.

153. Can we write Setter and Getter methods in Salesforce?

Yes, we use a getter method to return values for a controller. Each value computed by the controller and shown on the page should have a getter method.

On the other hand, we use the setter method to pass the user-defined values from the page markup to the controller. In the controller, we automatically execute the setter method.

154. Explain the Developer Console.

The developer console is an integrated development environment with a collection of tools. We use these tools to debug, create, and test applications in Salesforce.org.

155. Explain packages and different kinds of packages?

A package is a collection of components or associated applications. The following are the kinds of packages:

• Managed
• Unmanaged

We use managed packages to distribute and sell applications to clients. Developers sell user-friendly applications and licenses by using AppExchange for managed packages. These are entirely updatable during continuous upgrades; we remove fields or objects.

156. What are the ways to implement the metadata in Salesforce?

The following are the ways to implement metadata in Salesforce:

• By using Change Sets
• Eclipse with Force.com IDE
• Salesforce package
• Through Migration tools

157. Explain reRender Attribute Tag.

The reRender attribute defines an element's list that we can update dynamically through the Salesforce AJAX library. We do not need the entire page to refresh. Only a part of the page detected by the components is named in the “.rerender” attribute.

158. How can we display the Chatter Feed Record?

By using the <chatter: feed> component, we can display the chatter feed.

Example:

<apex:page>
<chatter: feed entityId=”{!$User.Id}”/>
</apex:page>  

159. Explain the Blob variable.

A blob variable is intended to store binary data. tostring() converts the blob back into a string.

string string1='test string';
Blob blob1 = Blob.valueof(myString);
String String2 = myBlob.toString();
System.debug(String2);

160. What is the use of apex:outputLink?

The apex:outputLink body comprises an image or text that we can display in the link.

<apex: outputlink value="https://mindmajix.com/" id="theLink">www.mindmajix.com </apex:outputLink>
