CompTIA Network+ (N10-007) — Question 627

A network technician has been attempting to gain access to a switch over the network after an extended power outage but has been unsuccessful. The technician runs a network scan and does not find the switch in the results. The switch is turned on, and the link lights are all green. Which of the following should the technician use to gain access to the switch?

Answer options

• A. SSH
• B. OOB
• C. VNC
• D. Telnet

Correct answer: B

Explanation

The correct answer is B, OOB (Out-of-Band) management, which allows access to the device outside of its normal network connection, ideal for situations where the device is not discoverable on the network. The other options, SSH, VNC, and Telnet, all require network connectivity to the switch, which is not currently possible in this scenario.
