AWS Certified Developer – Associate — Question 209

A developer wants to expand an application to run in multiple AWS Regions. The developer wants to copy Amazon Machine Images (AMIs) with the latest changes and create a new application slack in the destination Region. According to company requirements, all AMIs must be encrypted in all Regions. However, not all the AMIs that the company uses are encrypted.

How can the developer expand the application to run in the destination Region while meeting the encryption requirement?

Answer options

• A. Create a new AMIs, and specify encryption parameters. Copy the encrypted AMIs to the destination Region. Delete the unencrypted AMIs.
• B. Use AWS Key Management Service (AWS KMS) to enable encryption on the unencrypted AMIs. Copy the encrypted AMIs to the destination Region.
• C. Use AWS Certificate Manager (ACM) to enable encryption on the unencrypted AMIs. Copy the encrypted AMIs to the destination Region.
• D. Copy the unencrypted AMIs to the destination Region. Enable encryption by default in the destination Region.

Correct answer: A

Explanation

The correct answer is A because creating new AMIs with specified encryption parameters ensures that the new images meet the encryption requirement before being copied to the destination Region. Option B is incorrect as AWS KMS does not directly enable encryption on AMIs; option C is wrong since AWS Certificate Manager is not used for AMI encryption; and option D fails to meet the encryption requirement since it copies unencrypted AMIs.
