VCP-VCF Administrator 2024 Question 160
Single answerYou are managing a VMware Cloud Foundation environment where a mission-critical virtual machine (VM) is running. The VM requires a hardware upgrade to support increased workload demands. However, downtime must be minimized. What is the most appropriate sequence of actions to perform this task?
- A
Migrate the VM using vMotion to another host, power off the VM, perform the hardware upgrade, and power it back on.
- B
Take a snapshot of the VM, upgrade the hardware version while it is powered on, and monitor for issues.
- C
Create a clone of the VM, upgrade the hardware on the clone, and replace the original VM with the upgraded clone.
- D
Migrate the VM using vMotion to another host, upgrade the hardware version, and ensure compatibility with the destination host.
Show answer and explanation
Correct answer: A
Explanation
When upgrading the hardware version of a VM in VMware Cloud Foundation, the VM must be powered off, as hardware upgrades cannot occur while the VM is running. To minimize downtime for mission-critical VMs, vMotion can be used to migrate the VM to another host temporarily, ensuring continuity of services. Once the VM is powered off, the hardware can be upgraded safely.
- A. Correct.
This is the correct option. Migrating the VM using vMotion ensures no downtime, and performing the hardware upgrade after powering off the VM is the most reliable method to ensure compatibility and stability.
- B. Incorrect.
Upgrading the hardware version while the VM is powered on is not possible, as a VM must be powered off to upgrade its hardware version.
- C. Incorrect.
Cloning the VM and upgrading the hardware on the clone is not an efficient or standard practice in VMware environments, especially for a mission-critical VM.
- D. Incorrect.
Upgrading the hardware version while the VM is migrated to another host is not feasible without first powering off the VM. Additionally, hardware upgrades are not dependent on the destination host.
