2V0-21.23 Question 419
Select 3An organization is planning to update their VMware ESXi hosts to the latest version to address security vulnerabilities and improve performance. The administrator wants to ensure minimal downtime and a streamlined update process. Which of the following procedures should the administrator follow to correctly update their ESXi hosts with minimal disruption?
- A
Use VMware vSphere Lifecycle Manager (vLCM) to create a baseline and remediate the ESXi hosts.
- B
Manually download the ESXi ISO from VMware's website and perform an in-place upgrade on each host.
- C
Place the ESXi host into maintenance mode before applying the update.
- D
Ensure that all virtual machines are powered off before starting the ESXi update.
- E
Verify compatibility of the update with the existing hardware and vSphere environment prior to installation.
Show answer and explanation
Correct answers: A, C, E
Explanation
The correct procedure for updating VMware ESXi hosts involves using vSphere Lifecycle Manager (vLCM) for automation, placing the host into maintenance mode to avoid disruptions, and verifying compatibility to ensure a smooth update. These steps help minimize downtime and streamline the update process, making them essential for maintaining a robust and reliable virtualized environment.
- A. Correct.
Using VMware vSphere Lifecycle Manager (vLCM) is the recommended and streamlined method for managing and applying updates to ESXi hosts. It helps automate the process and reduces the chances of manual errors.
- B. Incorrect.
While downloading the ISO and performing a manual upgrade is an option, it is not the most efficient or recommended method for environments with multiple hosts, as it requires significant manual effort and risks downtime.
- C. Correct.
Placing the ESXi host into maintenance mode ensures that no virtual machines are running on the host during the update process, preventing potential disruptions or failures.
- D. Incorrect.
Powering off all virtual machines is not required for an ESXi update, as maintenance mode automatically migrates virtual machines to other hosts in the cluster if DRS is enabled.
- E. Correct.
Verifying hardware and environment compatibility ensures that the update will not cause issues post-installation, such as hardware incompatibility or unsupported configurations.
