Correct Answer
Use Azure Disk Snapshots of production HANA volumes to create QA disks, then recover HANA from the snapshot — takes 30–60 minutes regardless of DB size
Why This Answer Is Correct
Azure Disk Snapshots (or ANF snapshots) are near-instantaneous regardless of data volume size. For a 4TB HANA DB: snapshotting takes seconds, creating new managed disks from the snapshot takes minutes, and attaching to the QA VM and recovering HANA to a consistent state takes under an hour total. Full backup/restore of 4TB over network takes many hours. HSR replication to QA is complex and changes the replication topology. Azure Backup restore is slower and uses vault recovery bandwidth.
This question evaluates your knowledge of SAP HANA — a core concept tested in Microsoft Certified: Azure for SAP Workloads Specialty (AZ-120). Understanding SAP HANA is essential for designing scalable, secure, and cost-effective cloud architectures. Mastery of this topic will help you answer scenario-based questions confidently on exam day.
