VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 74

An architect is planning the physical server configuration for a vSAN-based infrastructure.
Which operations mode should a RAID controller support to minimize potential server downtime during physical disk failures?

Answer options

• A. RAID controller with Passthru mode
• B. RAID controller with RAID 5 mode
• C. RAID controller with RAID 10 mode
• D. RAID controller with RAID 6 mode

Correct answer: A

Explanation

The correct answer is A, as Passthru mode allows the disks to be directly managed by the vSAN, which minimizes downtime during failures. The other modes, like RAID 5, RAID 10, and RAID 6, involve additional overhead and complexity that can lead to longer recovery times during disk failures.
