Exam N10-009 Topic 1 Question 47 Discussion

Actual exam question for CompTIA's N10-009 exam
Question #: 47
Topic #: 1
You are setting up a new Access Point (AP) on a network where previous APs have been functioning correctly.
However, the new AP fails to power on. What is the most likely cause of the issue?

Suggested Answer: C Vote an answer

When deploying multiple Power over Ethernet (PoE) devices, the switch's power budget can be exhausted. If the available wattage on the switch cannot supply the additional AP, it will fail to power on. This is the most likely cause when previous APs worked fine but a new one does not.
* A. Signal strength affects wireless connectivity, not whether the AP powers up.
* B. Duplex mismatch causes poor throughput, not power failure.
* D. CRC errors point to cabling issues but do not prevent booting if no power is available.
