PAS-C01 Operations and Maintenance Practice Question

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
✓
Take a manual snapshot before the upgrade, then perform the upgrade.
Taking a manual snapshot before the upgrade provides a point-in-time backup that can be restored if the upgrade fails, enabling a rollback. RDS minor version upgrades are typically performed with minimal downtime (usually a few minutes). Option B is incorrect because enabling Multi-AZ does not provide a rollback mechanism; it only provides high availability during the upgrade. Option C is incorrect because the clone feature is specific to SAP HANA native tools, not RDS; RDS for SAP HANA does not support cloning for version upgrades. Option D is incorrect because creating a read replica does not facilitate rollback of the primary instance; read replicas are used for read scaling and cannot be used to revert an upgrade on the source.

Multi-AZ is for high availability, not for upgrade rollback.

Use the clone feature of SAP HANA to create a copy.
