VMware Carbon Black Cloud Endpoint Standard Specialist — Question 4

During yesterday's business hours, a cache drive failed on one of the vSAN 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 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. 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.
• B. Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.
• C. Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.
• D. 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.

Correct answer: A

Explanation

The correct answer is A because it involves manually removing the existing disk group and replacing the failed device, which ensures that the new drive is correctly integrated into the system. Options B and C incorrectly state that vSAN will automatically create a new disk group or allocate storage without manual intervention, which is not the correct process for replacing a drive. Option D suggests using maintenance mode and automatic rebuilding, but the initial step of removing the disk group is not included, which is necessary in this scenario.
