2V0-21.23 Question 422
Select 3An administrator is tasked with updating the network drivers on a VMware ESXi host to ensure compatibility with new hardware. The environment uses vSphere Lifecycle Manager (vLCM) for updates. Which steps should the administrator take to update the drivers while ensuring minimal disruption to the environment?
- A
Download the appropriate driver VIBs from the vendor's website and manually install them using the ESXi shell.
- B
Use vSphere Lifecycle Manager to import the updated driver as part of a custom image or baseline.
- C
Perform a hardware compatibility check in vSphere Lifecycle Manager to ensure the new drivers are supported by the host.
- D
Place the ESXi host into maintenance mode before applying the new driver update.
- E
Directly apply the driver update on the production host without any pre-checks to minimize downtime.
Show answer and explanation
Correct answers: B, C, D
Explanation
Updating ESXi drivers should follow a structured process to ensure compatibility and minimal disruption. vSphere Lifecycle Manager is the preferred tool for managing updates in a centralized and compliant manner. Compatibility checks and placing the host in maintenance mode are essential steps to ensure a smooth update process. Manually applying updates or skipping checks can lead to stability issues and should be avoided.
- A. Incorrect.
Manually installing drivers using the ESXi shell is not recommended in environments managed by vSphere Lifecycle Manager, as it bypasses the centralized management and compliance capabilities of vLCM.
- B. Correct.
Using vSphere Lifecycle Manager allows the administrator to manage updates centrally, ensuring that the driver update is part of a validated baseline or custom image for consistent deployment across the environment.
- C. Correct.
Performing a hardware compatibility check ensures that the updated drivers are supported by the ESXi host and its hardware, reducing the risk of compatibility issues.
- D. Correct.
Placing the ESXi host into maintenance mode ensures that virtual machines are safely migrated or shut down, preventing disruption during the update process.
- E. Incorrect.
Directly applying the driver update on a production host without pre-checks is risky and may lead to downtime or host instability due to potential compatibility issues.
