VMware NSX-T Data Center for Operators — Question 19

A cloud administrator needs to configure a VM storage policy for virtual machines that will host a business critical application. The environment consists of a single cluster with six hosts. The application is storage I/O intensive and redundancy must be provided at the highest level possible.
Which VM storage policy settings should the administrator configure to meet these requirements?

Answer options

• A. RAID-1 - FTT=3
• B. RAID-1 - FTT=2
• C. RAID-5
• D. RAID-6

Correct answer: B

Explanation

The correct answer is B, as RAID-1 with FTT=2 provides high redundancy suitable for a storage I/O intensive application, allowing for the failure of up to two hosts without data loss. Option A, with FTT=3, is excessive for a six-host cluster, while RAID-5 and RAID-6 do not offer the same level of redundancy and performance needed for business-critical applications.
