CompTIA Network+ (N10-009) — Question 484

A security engineer is trying to connect cameras to a 12-port PoE switch, but only eight cameras turn on. Which of the following should the engineer check first?

Answer options

• A. Ethernet cable type
• B. Voltage
• C. Transceiver compatibility
• D. DHCP addressing

Correct answer: B

Explanation

The engineer should first check the Voltage, as Power over Ethernet (PoE) requires sufficient voltage to power all connected devices. If the voltage is inadequate, only a portion of the devices will turn on, while the other options are less likely to be the primary cause of the issue.
