CompTIA Network+ N10-006 Q55

Which of the following requires the network administrator to schedule a maintenance window?

A. When a company-wide email notification must be sent.
B. A minor release upgrade of a production router.
C. When the network administrator’s laptop must be rebooted.
D. A major release upgrade of a core switch in a test lab.

Correct Answer: B
Section: Network operations

Explanation:
During an update of a production router the router would not be able to route packages and the network traffic would be affected. It would be necessary to announce a maintenance window.
In information technology and systems management, a maintenance window is a period of time designated in advance by the technical staff, during which preventive maintenance that could cause disruption of service may be performed.
