HPE Aruba Certified Central Associate (ACCA) — Question 45

A technician installed a new 550 series access point, which is cabled back to a CX 6000 series switch. However, there are no lights on the AP.
What could cause this?

Answer options

• A. STP has not been configured.
• B. PoE is disabled on the interface.
• C. The AP can’t connect to HPE Aruba Networking Central.
• D. The wrong VLAN has been configured.

Correct answer: B

Explanation

The correct answer is B because if Power over Ethernet (PoE) is disabled on the interface, the access point won't receive power, leading to no lights being displayed. Option A is incorrect as STP configuration does not affect power delivery. Option C is irrelevant as connectivity to HPE Aruba Networking Central does not impact the power to the device. Option D also does not explain the lack of power, as VLAN configuration issues would not cause the AP to have no lights.
