CompTIA Network+ (N10-009) — Question 99
A network administrator is in the process of installing 35 PoE security cameras. After the administrator installed and tested the new cables, the administrator installed the cameras. However, a small number of the cameras do not work. Which of the following is the most likely reason?
Answer options
- A. Incorrect wiring standard
- B. Power budget exceeded
- C. Signal attenuation
- D. Wrong voltage
Correct answer: B
Explanation
The most likely reason for some cameras not working is that the power budget has been exceeded, meaning that the total power required by the cameras surpasses what the PoE switch can supply. Incorrect wiring standard, signal attenuation, and wrong voltage could contribute to issues but are less likely to be the primary cause in this scenario.
