ACMA Access Point Deployment 5

Question 1

What is the purpose of configuring an AP's 'LMS IP' (Local Management Switch) during deployment?

Accepted Answer

To specify the primary controller the AP should connect to

Answer

The LMS IP tells the AP which controller to contact first for management, enabling directed controller discovery without relying solely on DHCP option 43.

Question 2

An Aruba AP deployed outdoors begins experiencing interference from a neighboring business's Wi-Fi network on channel 6. Which ARM feature should resolve this automatically?

Accepted Answer

Channel quality monitoring with automatic reassignment

Answer

ARM continuously monitors channel quality and automatically reassigns the AP to a less congested channel when interference is detected.

Question 3

What happens to an Aruba IAP (Instant AP) cluster when the Virtual Controller AP fails?

Accepted Answer

The cluster elects a new Virtual Controller automatically

Answer

Aruba Instant AP clusters automatically elect a new Virtual Controller from the remaining APs, ensuring seamless continuity.

Question 4

Which deployment consideration is most important when mounting an Aruba AP on a metal ceiling grid?

Accepted Answer

Using an isolation mount to prevent RF reflection from the grid

Answer

An isolation mount (mounting bracket with non-metallic standoff) prevents the AP's internal antennas from being detuned by the metal ceiling grid.

Question 5

During a post-deployment validation, an AP shows correct association but clients report slow throughput. Which metric should be checked first?

Accepted Answer

Channel utilization and retry rates on the AP radio

Answer

High channel utilization and elevated retry rates indicate RF congestion or interference that directly degrades client throughput.
