A video provider has a big proportion of EC2 instance store volumes as many of their workloads require very quick disk IO. Compared with EBS counterparts, instance store volumes are physically attached to the host and have better performance. However, they still need to work out a suitable method to create an AMI for the instance store volume. How can you do it?

Answer options:

A.Instance store volume cannot have AMI images that are only available for EBS volumes.
B.They can only create an AMI using AWS EC2 CLI command for instance store volumes.
C.The AMI can be created by using AWS EC2 console, CLI or SDK for instance store volumes.
D.The AWS CLI tools can be used to create a bundle for the volume and upload it to S3. Then register the AMI to the file in the S3 bucket.

Correct Answer D
The following diagram summarizes the process of creating an AMI from an instance store-backed instance.
Option A is incorrect: Because an AMI can be created to store volume according to https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/creating-an-ami-instance-store.html.
Option B is incorrect: Because AWS EC2 CLI can only be used to generate AMI for EBS volumes.
Option C is incorrect: Because the AMI creation process for instance store volumes is different from Amazon EBS-backed AMIs. AMI tools such as ec2-bundle-vol and ec2-upload-bundle are required.
Option D is CORRECT: Because this has used the correct procedures described in https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/create-instance-store-ami.html#amazon_linux_instructions.
