VMware vSAN Administrator (2025) — Question 29

An organization is designing a VMware Cloud Foundation (VCF) solution hosting a business-critical database. The application owners specified the following requirements:
All workload domains will use vSAN for storage.
A maximum acceptable data loss of 5 minutes (Recovery Point Objective (RPO) = 5 minutes)
An automated failover in case of a site outage where Recovery Time Objective should not exceed 30 minutes.
The performance impact should be minimized.
Which design approach aligns with the application's requirement?

Answer options

• A. Use vSAN stretched cluster.
• B. Use synchronous replication on the storage array level.
• C. Use asynchronous replication with snapshots taken every 30 minutes to reduce storage impact.
• D. Configure backup-based recovery with backup jobs scheduler set to every 30 minutes.

Correct answer: A

Explanation

The correct answer is A, as a vSAN stretched cluster provides both the required RPO of 5 minutes and allows for automated failover, ensuring minimal performance impact. Option B, synchronous replication, may not meet the RPO requirement effectively and could introduce latency. Option C, asynchronous replication with longer snapshot intervals, does not fulfill the RPO requirement, and option D relies on backups, which is not suitable for the specified RPO and RTO needs.
