HPE Aruba Certified Network Security Professional (ACNSP) — Question 74

Which statement is correct regarding powering an Aruba Access Point?

Answer options

• A. PoE or PoE+ is only used with Ethernet that is carried over multi-mode fiber cabling.
• B. Using switchports for this reason is unnecessary, because Aruba Access Points typically use an AC to DC power adapter to draw power.
• C. PoE or PoE+ enabled switchports are rarely used given concerns about causing electrical interference, with the data also carried over Ethernet cabling.
• D. Most administrators use PoE or PoE+ enabled switchports to provide both Ethernet connectivity and power to the AP.

Correct answer: D

Explanation

The correct answer is D because most administrators prefer using PoE or PoE+ switchports to simplify the setup by providing both power and data connectivity through the same cable. Option A is incorrect as PoE is not limited to multi-mode fiber, option B misrepresents the common power methods for APs, and option C incorrectly suggests that electrical interference is a common issue with PoE switchports.
