- A
Check the VMware Compatibility Guide to verify the new driver version is supported for the ESXi version.
- B
Directly upload the driver VIB file to the ESXi host and install it using the esxcli command without verifying compatibility.
- C
Place the ESXi host into maintenance mode before starting the driver update process.
- D
Reboot the ESXi host immediately after uploading the driver file to ensure changes take effect.
- E
Check the VMware Hardware Compatibility List (HCL) to confirm the driver is compatible with the host hardware.
Show answer and explanation
Correct answers: A, C, E
Explanation
To successfully update a driver on an ESXi host while maintaining stability, it is critical to verify compatibility using VMware's Compatibility Guide and Hardware Compatibility List (HCL). Placing the host into maintenance mode ensures no active workloads are disrupted during the update process. Skipping these steps or failing to validate compatibility could result in operational issues or host instability.
- A. Correct.
Checking the VMware Compatibility Guide ensures that the driver is supported for the specific version of ESXi, reducing the risk of instability.
- B. Incorrect.
Installing a driver without verifying compatibility could result in host instability or other operational issues.
- C. Correct.
Placing the ESXi host into maintenance mode prevents disruptions to running workloads and ensures a safer update process.
- D. Incorrect.
Rebooting immediately after uploading the driver is not recommended since the driver must first be installed properly and verified.
- E. Correct.
The VMware Hardware Compatibility List (HCL) is an essential resource to confirm compatibility between the driver, hardware, and ESXi version.
