Access Point Deployment Flashcards

An Aruba AP is placed in a warehouse with high ceilings and metal shelving. Which antenna type best mitigates multipath interference in this environment?

Answer: Patch directional antenna

Patch directional antennas focus signal in a specific direction, reducing multipath reflections common in metal-rich environments.

Which Aruba AP deployment mode allows the AP to provide wireless access even when the controller is unreachable?

Answer: Survivability mode

Survivability mode allows an AP to continue serving clients using cached configuration when controller connectivity is lost.

When deploying APs in a high-density lecture hall, what is the primary design consideration?

Answer: Using lower transmit power with more APs for capacity

High-density environments require more APs at lower power to increase capacity while controlling co-channel interference.

What is the purpose of the Aruba AP's 'local probe response' feature during deployment?

Answer: To respond to client probe requests locally without forwarding to the controller

Local probe response allows the AP to answer client probe requests directly, reducing controller load and improving roaming speed.

An AP is deployed outdoors and loses its DHCP lease. Which IP address will it attempt to use to maintain connectivity?

Answer: The last valid DHCP address from its lease

Aruba APs retain the last valid DHCP address to maintain controller connectivity when DHCP renewal fails.

Which CLI command on an Aruba controller verifies that an AP has successfully joined and is in an 'up' state?

Answer: show ap active

'show ap active' displays all APs currently connected to the controller with their operational status.

A newly deployed Aruba AP continuously reboots after receiving its image. What is the most likely cause?

Answer: Insufficient PoE power budget on the switch port

Insufficient PoE power causes the AP to draw more current than available, leading to repeated power cycles and reboots.
