1.When you view the block device mapping for your instance, you can see only the EBS volumes, not the instance store volumes.

A.Depends on the instance type

B.FALSE

C.Depends on whether you use API call

D.TRUE

Answer:D

TRUE

Explanation:

When you view the block device mapping for your EC2 instance:

You can see only the EBS (Elastic Block Store) volumes attached to your instance.
Instance store volumes (also known as ephemeral storage) are not displayed in the block device mapping in certain views, such as the AWS Management Console.
This happens because instance store volumes are temporary storage that exists only for the lifetime of the instance and is not persistent like EBS.

5.By default what are ENIs that are automatically created and attached to instances using the EC2 console set to do when the attached instance terminates?

A.Remain as is

B.Terminate

C.Hibernate

D.Pause

Answer:B

Terminate

Explanation:

An Elastic Network Interface (ENI) is a virtual network card that attaches to an EC2 instance.

By default, when an EC2 instance is launched via the EC2 console, the primary ENI (created automatically) is set to terminate along with the instance.
This behavior ensures that network resources are cleaned up when an instance is deleted.
