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
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.
