VMware Carbon Black Cloud Enterprise EDR Specialist — Question 13

A customer has deployed a new vSAN Cluster with the following configuration:
6 x vSAN ReadyNodes

All Flash -
12 TB Raw Storage
vSAN 8 is deployed with ESA.
VMs are configured with a RAID-5 VM policy.
During failure testing, before the new platform is placed into production one of the ESXi hosts is made unavailable.
Which RAID-5 data placement schemes will vSAN use with this failure condition?

Answer options

• A. vSAN can protect the platform using adaptive RAID 5 if the ESXi host fails to return
• B. VMware HA will migrate the storage objects to another node in the cluster
• C. Some VM data will be unavailable until the failed ESXi host is recovered
• D. The data components on the hosts will be marked as degraded

Correct answer: A

Explanation

The correct answer is A because vSAN utilizes adaptive RAID 5 to maintain data integrity when an ESXi host is unavailable, ensuring continued protection of the platform. Option B is incorrect as VMware HA does not migrate storage objects; it focuses on VM availability. Option C is misleading because while some data may be impacted, adaptive RAID 5 can still provide protection. Option D is also incorrect in this context, as the use of adaptive RAID 5 prevents the marking of all data components as degraded.
