2V0-21.23 Question 337
Single answerA VMware administrator is tasked with updating the virtual hardware version of a virtual machine (VM) to ensure compatibility with the latest VMware vSphere features. The VM is running a critical application, and downtime must be minimized. What is the recommended process to update the virtual hardware version while ensuring the lowest risk to the application?
- A
Power off the VM, then upgrade the virtual hardware version from the vSphere Client.
- B
Upgrade the virtual hardware version while the VM is powered on to avoid downtime.
- C
Take a snapshot of the VM, power off the VM, upgrade the virtual hardware version, and then power it back on.
- D
Migrate the VM to another ESXi host, upgrade the virtual hardware version, and then migrate it back.
Show answer and explanation
Correct answer: C
Explanation
To upgrade the virtual hardware version of a VM, the VM must be powered off. Taking a snapshot before performing the upgrade ensures that the administrator can revert the VM to its previous state if any issues arise during the process. This approach minimizes risk to the application while allowing the hardware upgrade to be completed safely.
- A. Incorrect.
This is a valid method to upgrade the virtual hardware version, but it does not minimize risk to the application because no snapshot is taken beforehand.
- B. Incorrect.
Virtual hardware upgrades cannot be performed on a running VM, so this option is invalid.
- C. Correct.
This is the recommended approach for upgrading virtual hardware. Taking a snapshot allows recovery if the upgrade causes issues, and powering off the VM is required to perform the upgrade.
- D. Incorrect.
Migrating the VM to another ESXi host does not directly address the requirements for upgrading the virtual hardware version while minimizing risk. This option is unnecessary.
