What is the purpose of configuring an AP's 'LMS IP' (Local Management Switch) during deployment?
Answer: To specify the primary controller the AP should connect to
The LMS IP tells the AP which controller to contact first for management, enabling directed controller discovery without relying solely on DHCP option 43.
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?
Answer: Channel quality monitoring with automatic reassignment
ARM continuously monitors channel quality and automatically reassigns the AP to a less congested channel when interference is detected.
What happens to an Aruba IAP (Instant AP) cluster when the Virtual Controller AP fails?
Answer: The cluster elects a new Virtual Controller automatically
Aruba Instant AP clusters automatically elect a new Virtual Controller from the remaining APs, ensuring seamless continuity.
Which deployment consideration is most important when mounting an Aruba AP on a metal ceiling grid?
Answer: Using an isolation mount to prevent RF reflection from the grid
An isolation mount (mounting bracket with non-metallic standoff) prevents the AP's internal antennas from being detuned by the metal ceiling grid.
During a post-deployment validation, an AP shows correct association but clients report slow throughput. Which metric should be checked first?
Answer: Channel utilization and retry rates on the AP radio
High channel utilization and elevated retry rates indicate RF congestion or interference that directly degrades client throughput.
What Aruba deployment feature allows different SSIDs on the same AP to be forwarded to different upstream VLANs?
Answer: Per-SSID VLAN mapping
Per-SSID VLAN mapping assigns each SSID to a specific upstream VLAN, enabling traffic segmentation from a single AP.
An organization deploys Aruba APs in a hospital where medical devices use 802.11b at 2.4 GHz. What AP configuration protects performance for newer clients while maintaining compatibility?
Answer: Enable 802.11b protection mechanisms and set minimum basic rate to 5.5 Mbps
Setting the minimum basic rate to 5.5 Mbps excludes the slowest 802.11b rates while protection mechanisms accommodate remaining legacy devices.
