Answer choices
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
✓
Amazon RDS does not support the SAP HANA engine.
Amazon RDS does not support SAP HANA as a database engine. SAP HANA must be installed on EC2 instances or on bare metal. Option A is incorrect because the template references the InstanceType parameter correctly using the Ref function. Option B is incorrect because while db.x1e.2xlarge is a valid RDS instance class for some engines (e.g., SQL Server), it is not valid for a non-existent RDS engine; but the primary issue is that SAP HANA is not supported on RDS at all. Option C is incorrect because the AMI ID is not relevant; RDS does not use AMIs; the stack would fail before checking AMI.
