Q82. A user has created a blank EBS volume in the US-East-1 region. The user is unable to attach the volume to a running instance in the same region. What could be the possible reason for this?
A. The instance must be in a running state. It is required to stop the instance to attach volume

D. The instance has enabled the volume attach protection
Answer: B
Explanation:
An EBS volume provides persistent data storage. The user can attach a volume to any instance provided they are both in the same AZ. Even if they are in the same region but in a different AZ, it will not be able to attach the volume to that instance.

Q83. A user wants to access RDS from an EC2 instance using IP addresses. Both RDS and EC2 are in the same region, but different AZs. Which of the below mentioned options help configure that the instance is accessed faster?
A. Configure the Private IP of the Instance in RDS security group
B. Security group of EC2 allowed in the RDS security group
C. Configuring the elastic IP of the instance in RDS security group
D. Configure the Public IP of the instance in RDS security group
Answer: A
Explanation:
If the user is going to specify an IP range in RDS security group, AWS recommends using the private IP address of the Amazon EC2 instance. This provides a more direct network route from the Amazon EC2 instance to the Amazon RDS DB instance, and does not incur network charges for the data sent outside of the Amazon network.

A. Its incremental
B. It can be used to launch a new instance
C. It is stored in the same AZ as the volume

Hence the statement "|t is stored in the same AZ as the volume" is incorrect.
