We have categorized AWS Architect Interview Questions - 2022 (Updated) into 2 levels they are:
Instance performs a regular shut down when it is stopped. It then performs transactions. As the entire EBS volumes remain present, it is possible to start the instance anytime again when you want. The best thing is when the instance remains in the stopped state, users don’t need to pay for that particular time.
Upon termination, the instance performs a regular shutdown. After this, the Amazon EBS volumes start deleting. You can stop them from deleting simply by setting the “Delete on Termination” to false. Because the instance gets deleted, it is not possible to run it again in the future.

It should be set to the Dedicated Instance for smoothly running it on single-tenant hardware. Other values are not valid for this operation.
EIP stands for Elastic Internet Protocol address. Costs are acquired with an EIP when the same is associated and allocated with a stopped instance. In case only one Elastic IP is there with the instance you are running, you will not be charged for it. However, in case the IP is attached to a stopped instance or doesn’t attach to any instance, you need to pay for it.
Spot instance is similar to bidding and the price of bidding is known as the Spot price. Both Spot and on-demand instances are pricing models. In both of them, there is no commitment to the exact time from the user end. Without upfront payment, Spot instance can be used while the same is not possible in the case of an On-demand instance. It needs to be purchased first and the price is higher than the spot instance.
The Multi-AZ deployments are simply available for all the instances irrespective of their types and use.

Actually, it depends largely on the type of Instance, as well as on the specification of network performance. In case they are started in the placement group, you can expect the following parameters
20 Gbps in case of full-duplex or when in multi-flow
Up to 10 Gbps in case of a single-flow
Outside the group, the traffic is limited to 5 Gbps.
It is possible to use i2.large or c4.8x large Instance for this. However, c.4bx needs a better configuration on the PC. At some stages, you can simply launch the EMR for the automatic configuration of the server you. Data can be put into S3 and EMR is able to pick it from there. It will load your data in S3 again after processing it.

AMI is generally considered as the template for virtual machines. While starting an instance, it is possible to select pre-baked AMI’s that AMI commonly has in them. However, not all AMIs are available to use free of cost. It is also possible to have a customized AMI and the most common reason to use the same is nothing but saving the space on Amazon Web Service. This is done in case a group of software is not required and AMI can simply be customized in that situation.
For this, there are various parameters that should be kept in mind. Some of them are performance, pricing, latency, as well as response time.
Well, the private address is directly correlated with the Instance and is sent back to EC2 only in case it is terminated or stopped. On the other side, the public address is correlated in a similar manner with the Instance until it is terminated or stopped. It is possible to replace the public address with Elastic IP. This is done when a user wants it to stay with Instance as per the need.
No, it’s not possible. We need more than one elastic IP in such a case.

This can be done through several practices. A review of the protocols in the security group is to be monitored regularly and it is to be ensured that the principle of least is applicable over there. The next practice is using access management and AWS identity for controlling and securing access. Access is to be restricted to hosts and networks that are trusted. In addition to this, only those permissions are opened which are required and not any other. It would also be good to disable password-based logins for the instances.
It contains two states and they are:
It is possible to customize these states in a few EC2 instances which enable users to customize the processor as per need.
There is a policy named custom IAM user policy that limits the S3 API in the bucket.
Yes, it’s possible if the instances are having root devices and are supported by the instance storage. Amazon uses one of the very reliable, scalable, fast, as well as inexpensive networks for hosting all their websites. With the help of S3, it is possible for the developers to get access to the same network. There are tools available in AMI’s that users can consider when it comes to executing systems in EC2. The files can simply be moved between EC2 and S3.
Yes, it’s possible. There are certain methods for this. First is simply copying from different hosts to the same Snowball. Another method is by creating a group of smaller files. This is helpful as it cut down the encryption issues. Data transfer can also be enhanced by simply copying operations again and again at the same time provided the workstation is capable to bear the load.
Amazon Transfer Acceleration is a good option. There are other options such as Snowball but the same doesn’t support data transfer over a very long distance such as among continents. Amazon Transfer Acceleration is the best option because it simply throttles the data with the help of network channels that are optimized and assure very fast data transfer speed.

This is a common approach that is considered when it comes to launching EC2 instances. Each instance will be having a default IP address if the instances are launched in Amazon VPC. This approach is also considered when you need to connect cloud resources with the data centers.
Yes, it’s possible. For this, first, a Virtual Private Network is to be established between the Virtual private cloud and the organization’s network. After this, the connection can simply be created and data can be accessed reliably.
This is because the private IP remains with the instance permanently or through the life cycle. Thus it cannot be changed or modified. However, it is possible to change the secondary private address.
They are needed to utilize the network with a large number of hosts in a reliable manner. Of course, it’s a daunting task to manage them all. By dividing the network into smaller subnets, it can be made simpler and the chances of errors or data loss can be eliminated up to an excellent extent.

Yes, it’s possible. They are generally considered when it comes to routing the network packets. Actually, when a subnet has several route tables, it can create confusion about the destination of these packets. It is because of no other reason than this there should be only one route table in a subnet. The route table can have unlimited records and therefore it is possible to attach multiple subnets to a routing table.
It is recommended to backup the Direct Connect as in case of a power failure you can lose everything. Enabling BFD i.e. Bi-directional Forwarding Detection can avoid the issues. In case no backup is there, VPC traffic would be dropped and you need to start everything from the initial point again.
CloudFront sent the content from the primary server directly to the cache memory of the edge location. As it’s a content delivery system, it tries to cut down the latency and that is why it will happen. If the operation is performed for the second time, the data would directly be served from the cache location.
Yes, it is possible. Cloud Front simply supports custom origins and thus this task can be performed. However, you need to pay for it depending on the data transfer rates.
In case you have hosts that are batch-oriented, there is a need for the same. The reason is provisional IOPs are known to provide faster IO rates. However, they are a bit expensive when compared to other options. Hosts with batch processing don’t need manual intervention from the users. It is because of this reason provisional IOPs are preferred.
RDS is basically a DBM service that is considered for relational databases. It is useful for upgrading and patching data automatically. However, it works for structured data only. On the other side, Redshift is used in Data analysis. It is basically a data warehouse service. When it comes to DynamoDB, it is considered when there is a need to deal with unstructured data. RDS is quick as compared to both Redshift and DynamoDB. All of them are powerful enough to perform their tasks without errors.
Yes, it’s possible. However, there is a strict upper limit of 750 hours of usage post which everything will be billed as per RDS prices. In case you exceed the limit, you will be charged only for the extra hours beyond 750.

Amazon Redshift and Amazon DynamoDB are the best options. Generally, data from e-commerce websites are unstructured manner. As both of them are useful for unstructured data, we can use them.
There are certain stages when the traffic needs to be re-verified for bugs unwanted files that raise security concerns. Connection draining helps in re-routing the traffic that comes from the Instances and which is in a queue to be updated.
