Show answer and explanation
Correct answers: A, C, D, E
Explanation
Updating drivers on an ESXi host requires careful planning to maintain compatibility and avoid disruptions. Administrators should always verify the driver's compatibility using the VMware Compatibility Guide (VCG) and prefer automated tools like VMware Update Manager (VUM) when available. In cases where manual installation is necessary, CLI tools can be used. A host reboot is essential to activate the new driver. Avoid bypassing VMware's compatibility checks by directly using drivers from hardware vendors without validation.
- A. Correct.
Checking the VMware Compatibility Guide (VCG) is critical to ensure the updated driver is supported for the specific ESXi version and hardware.
- B. Incorrect.
Downloading the driver directly from the hardware vendor without compatibility checks can lead to instability or unsupported configurations.
- C. Correct.
Using VMware Update Manager (VUM) to apply the driver update is a recommended approach if the driver is part of a vendor-provided depot.
- D. Correct.
Manually uploading and installing the updated driver using ESXi CLI tools is an appropriate method if the driver update is not available via VUM.
- E. Correct.
Rebooting the ESXi host is required after the driver update to load the new driver and ensure the changes take effect.
