A systems administrator is patching virtual servers in a private cloud environment and must ensure any failure induced by patching is resolved as soon as possible. Which of the following is the best method for addressing this issue?
A.
Uninstalling patches if the server is unresponsive after being patched
B.
Taking a full backup before patching and restoring from backup if the server is unresponsive after being patched
C.
Taking a snapshot before patching and reverting to the snapshot if a server is unresponsive after being patched
D.
Sending an alert to the on-call engineer if patching on a server fails for any reason
Explanation:
Snapshots allow administrators to quickly revert a virtual machine to a previous state before the patching process.
If the patch causes a failure, the snapshot can be restored almost instantly, minimizing downtime.
This method is faster than restoring from a backup, which can take longer depending on storage and network speeds.
