CompTIA Network+ (N10-007) — Question 277

A network technician is installing a new PTZ camera for the security department. The camera is capable of being powered via the Ethernet cable, but it is not powering on. The network technician has tested the cable and received positive results. Which of the following is MOST likely the issue?

Answer options

• A. The camera requires PoE+, but the switch is delivering only PoE.
• B. A straight-through cable is being used, but the camera requires a crossover cable.
• C. The camera is configured for the wrong segmented network.
• D. The cable has a bad pinout and needs to be reterminated.

Correct answer: A

Explanation

The correct answer is A because if the camera needs PoE+ and the switch only provides PoE, it won't receive sufficient power to operate. Option B is incorrect as modern devices typically auto-sense the cable type, and a straight-through cable should work. Option C is also not the issue since network segmentation would not prevent power delivery, and option D is ruled out since the cable has already been tested successfully.
