Q. What is an application pool?
A group of one or more URLs that are served by a particular worker process or set of worker processes.
Q. Why are application pools important?
They provide a way for multiple sites to run on the same server but still have their own worker processes and identity.
Q. What are zones?
Different logical paths (URLs meaning) of gaining access to the same SharePoint Web application.
Q. What are Web Application Policies?
Enables security policy for users at the Web application level, rather than at the site collection or site level. Importantly, they override all other security settings.
Q. What is a site collection?

Q. When would you use claims, and when would you use classic?
Classic is more commonly seen in upgraded 2007 environments whereas claims are the recommended path for new deployments.
Q. Describe the potential components for both a single server, and multiple servers, potentially several tiered farms:
A single-server SharePoint Server 2010 environment leverages a built-in SQL Server 2008 Express database. The problems with this environment is scalability, not being able to install the with built-in database on a domain controller, the database cannot be larger than 4 GB, and you cannot use User Profile Synchronization in a single server with built-in database installation.
An example of a multiple tier farm would be a three-tier topology, considered one of the more efficient physical and logical layouts to supports scaling out or scaling up and provides better distribution of services across the member servers of the farm. This is considered a good architecture since one can add Web servers to the Web tier, add app servers to the application tier, and add database servers to the database tier.

Q. Please describe what a Service Application is in SharePoint 2010.
Service applications in SharePoint 2010 are a set of services that can possibly be shared across Web applications. Some of these services may or may not be shared across the SharePoint 2010 farm. The reason these applications are shared is the overall reduction of resources required to supply the functionality these services cultivate.
Q. What are Service Application Groups used for?
Just provides a logical grouping of services that are scoped to a particular Web Application.
Q. How are Service Applications deployed in terms of IIS (Internet Information Services)?
They are provisioned as a single Internet Information Services (IIS) Web site.
Q. Explain how connections are managed with Service Applications.
A virtual entity is used that is referred to as a proxy, due to label in PowerShell.
Q. What are some common examples of SharePoint 2010 services architectures, and what are the advantages of each design?
The three most popular designs are single farms with either a single service application group or multiple service application groups, or Enterprise services farms.
Single farms with a single service application group are generally the most common, and have the advantages of easy deployment, simple service application allocation, effective resource utilization and cohesive management.
Single farms with multiple service application groups is less common, and have the advantage of potential individual management of service applications as well as allowing data isolation, and while being more complex to deploy and maintain allows targeting of sites to particular service applications.
Enterprise Service Farms is pretty uncommon as it is a complete farm dedicated to Service Applications but promotes autonomous management and high levels of data isolation.
Q. Are there any other type of relevant service architectures?
Depending on the environment requirements, a specialized farm can also be used in order to deploy specific services tailored to the organizational requirements which can aid in scaling out and conservation of resources.

Backup / DR Questions
Q. Describe how redundancy can be built into a SharePoint environment. Please be specific in regards to any auxiliary components.
Multiple front-end web servers (WFE’s) can be deployed and correlated through Windows NLB or anything approach. Application servers can be deployed into the farm for a variety of purposes, depending on organizational requirements. Databases can be clustered or mirrored, again depending on requirements and environment.
Q. From a basic standpoint, what is the difference between SQL clustering and mirroring?
Clustering provides a failover scenario whereby one or more nodes can be swapped as active depending on whether a node goes down. In mirroring, transactions are sent directly from a principal database and server to a mirror database to establish essentially a replica of the database.
