VMware vSphere 6 Beta Foundations — Question 8

An administrator is designing a vSphere cluster with the VSAN default policy. The requirement is to maintain full redundancy of data and virtual disks during any patching or maintenance of this cluster.
What is needed to meet the needs of this scenario?

Answer options

• A. A minimum of four hosts in the cluster
• B. VMware Proactive HA
• C. Multiple disk groups per host
• D. Use of RAID-5/6 erasure coding

Correct answer: B

Explanation

The correct answer is B, VMware Proactive HA, as it allows for automated resource management and ensures that redundancy is maintained during maintenance. Option A is incorrect because while having four hosts is beneficial, it does not guarantee redundancy during maintenance. Option C is not relevant to redundancy requirements, and option D, while providing data protection, does not specifically address the need during maintenance activities.
