Explanation
Updating a standalone ESXi host requires the administrator to follow a structured process to ensure minimal downtime and proper patch application. Key steps include placing the host in Maintenance Mode, applying the patch using tools like 'esxcli', verifying the update, and rebooting the host. Skipping any of these steps may lead to incomplete updates or system instability.
- A. Correct.
Placing the ESXi host into Maintenance Mode ensures no VMs are running on the host during the update, minimizing risks during the process.
- B. Correct.
The 'esxcli software vib update' command is a valid method to manually update an ESXi host using downloaded patch files.
- C. Correct.
Verifying the ESXi host's version after the update ensures that the patch was successfully applied.
- D. Correct.
Rebooting the ESXi host is required to complete the patch installation process.
- E. Incorrect.
Uploading the patch file and applying it without interrupting running VMs is not possible. Updates require the host to be in Maintenance Mode, which involves shutting down or migrating VMs.
