HPE Aruba Certified Switching Professional (ACSP) — Question 38

An ArubaOS switch provides PoE+ to several Aruba APs. Users might also connect PoE devices to this switch. In a situation where the switch PoE capacity is exceeded, the network administrator wants to ensure that the switch continues to power the APs in preference to other devices.
What should the administrator do to achieve this goal?

Answer options

• A. Set the PoE priority for the ports connected to APs to critical.
• B. Set the PoE class for the ports connected to APs to Class 5.
• C. Make sure that LLDP MED is enabled on both the switch ports and the APs.
• D. Set the PoE allocation on the ports connected to APs to the maximum value permitted by PoE+.

Correct answer: A

Explanation

Setting the PoE priority for the ports connected to APs to critical ensures that those ports receive power first when the switch is under load. Other options do not specifically prioritize the APs over other devices, and while they may enhance functionality, they do not directly address the need to maintain power for the APs in case of PoE capacity being exceeded.
