In the industry, desktops are typically cloned and images are used on
multiple PCs. Explain how using the restore point utility can help with the
rebuilding and testing of PCs.
Having a restore point is crucial when it comes to rebuilding and
testing PCs. From a rebuilding standpoint, if a PC gets infected with
a virus and must be completely wiped to alleviate the issue, having
a restore point with critical data is essential to keep the business
running. A restore point might also fix an issue with an OS update
that might cause your software or hardware to fail as it was not
intended for or updated to the right patch to allow it to interface
with the OS without issue. This is critical in testing for the same
purpose, you may want to see how the most recent windows
update affects all your software, so you can update a test PC and if
things go poorly, restore to before the most recent update.

Explain why it is important to close ports that are not being used within a
computer system.
Closing ports not being utilized is critical for protecting your
network and computers. Having an open port that is not utilized
leaves you at risk of someone utilizing that port breaching your
system and uploading unwanted malware. It is also critical to
protect against potential exploits from compromised coworkers
who might know the system and can utilize port access to bypass
firewalls and security.
An open port not being used is like an open
door to a house, it allows the potential of theft, break-in, and
destruction of information on the PC.
