VMware Carbon Black Cloud Enterprise EDR Specialist — Question 59

During yesterday's business hours, a cache drive failed on one of the vSAN OSA nodes. The administrator reached out to the manufacturer and received a replacement drive the following day. When the drive failed, vSAN started a resync to ensure the health of the data, and all objects are showing a healthy and compliant state. The vSAN administrator needs to replace the failed cache drive.
Which set of steps should the vSAN administrator take?

Answer options

• A. Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.
• B. Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replace the failed cache device. Afterwards, vSAN will rebuild the disk group automatically.
• C. Remove the existing vSAN disk group, and physically replace the device. Then, check to verify that the ESXi host automatically detects the new device. Afterwards, manually recreate the Disk Group.
• D. Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.

Correct answer: C

Explanation

The correct answer is C because removing the existing disk group and replacing the device ensures a clean state for the new hardware. The other options either complicate the process by introducing unnecessary steps or do not guarantee that the new device will be properly configured and recognized by the system.
