PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is running SAP on AWS and wants to use a custom AMI for SAP application servers. They need to ensure that the AMI is encrypted using AWS KMS. Which step is required to launch encrypted instances from this AMI?
⚠ Common exam trap
Many candidates confuse encrypting the instance's root volume at launch (option C) with encrypting the AMI itself, not realizing that only a copy operation with a KMS key creates a persistently encrypted AMI.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Copy the AMI and specify a KMS key for encryption.
To launch encrypted instances from an unencrypted custom AMI, you must first copy the AMI and specify a KMS key for encryption during the copy process. This creates an encrypted AMI that can then be used to launch encrypted instances. AWS does not allow you to directly encrypt an existing AMI in place; the copy operation is the required mechanism.
