VMware Carbon Black Cloud Enterprise EDR Specialist — Question 7

A customer has deployed a new vSAN cluster with the following configuration:
5 x vSAN ReadyNodes

All Flash -
12 TB Raw Storage
vSAN 8 is deployed with ESA.
New VMs are configured with a RAID-5 VM policy.
Which statement is accurate?

Answer options

• A. vSAN will use a 2+1 RAID-5 data placement scheme with parity will be used
• B. RAID 5 will provide an FTT=2 level of protection in this case
• C. vSAN will use a 4+1 RAID-5 data placement scheme with parity will be used
• D. vSAN will spread the components across all of the disk groups

Correct answer: A

Explanation

The correct answer is A because a 2+1 RAID-5 configuration means two data blocks and one parity block, which is applicable given the vSAN setup. Option B is incorrect as RAID 5 typically provides FTT=1, not FTT=2. Option C is wrong because the stated RAID-5 scheme does not align with the configuration details. Option D is misleading since while components are spread across disk groups, it does not accurately address the RAID-5 configuration in question.
