A system administrator has noticed vulnerability on a high impact production server. A recent update was
made available by the vendor that addresses the vulnerability but requires a reboot of the system
afterwards. Which of the following steps should the system administrator implement to address the
vulnerability?

A.
Test the update in a lab environment, schedule downtime to install the patch, install the patch and
reboot the server and monitor for any changes

B.
Test the update in a lab environment, backup the server, schedule downtime to install the patch, install
the patch, and monitor for any changes

C.
Test the update in a lab environment, backup the server, schedule downtime to install the patch, install
the update, reboot the server, and monitor for any changes

D.
Backup the server, schedule downtime to install the patch, installs the patch and monitor for any
changes

Explanation:
We have an update to apply to fix the vulnerability. The update should be tested first in a lab
environment, not on the production server to ensure it doesn’t cause any other problems with the server.
After testing the update, we should backup the server to enable us to roll back any changes in the event
of any unforeseen problems with the update. The question states that the server will require a reboot.
This will result in downtime so you should schedule the downtime before installing the patch. After
installing the update, you should monitor the server to ensure it is functioning correctly.Incorrect Answers:
A: This answer is almost complete but is omits the step of backing up the server. We should backup the
server to enable us to roll back any changes in the event of any unforeseen problems with the update.
B: This answer is almost complete but is omits the step of rebooting the server. The question states that
the update requires a reboot of the server.
D: This answer omits the important step of testing the update. Updates should always be testing in a lab
environment before being deployed to productions servers.
