An Aruba switch port is configured as a trunk but a downstream AP is not receiving its management VLAN. What is the most likely misconfiguration?
Answer: The native/untagged VLAN on the trunk does not match the AP's expected management VLAN
APs typically expect their management traffic on the native (untagged) VLAN of the trunk port; a mismatch prevents the AP from obtaining a DHCP address and contacting the controller.
In Aruba Central, where would an administrator go to see the historical RF health score trend for a specific floor plan over the past 30 days?
Answer: AI Insights > Network Health > Location-based reports
Aruba Central's AI Insights / Network Health section provides location-aware historical RF health scores and trend graphs for floor-level analysis.
A client is associated at MCS0 on 5 GHz despite being within 3 meters of the AP. Which troubleshooting action should be taken first?
Answer: Check for a sticky client issue and verify minimum RSSI enforcement is configured
A client associated at MCS0 at close range typically indicates a sticky client that never re-evaluated its connection; enforcing minimum RSSI thresholds forces disconnection and reconnection at a better rate.
Which command on an Aruba Mobility Controller would help identify if a specific user's traffic is being dropped by a firewall policy?
Answer: show datapath user
'show datapath user ' displays the user's role, ACL assignments, and packet counters including drops attributable to the applied firewall policy.
Aruba NetEdit is primarily used for which network management function?
Answer: Configuration management, change tracking, and network validation for wired switches
Aruba NetEdit provides configuration management, version control, and pre/post-change validation specifically for Aruba wired switch deployments.
A technician uses 'show ap debug counters' on an Aruba controller and sees high 'tx-drop' values on an AP. What does this most likely indicate?
Answer: The AP's transmit buffer is overflowing due to RF congestion or a rate mismatch
High tx-drop counters on an AP typically point to transmit queue overflow caused by RF congestion, low data rates, or mismatched QoS settings overwhelming the radio.
In a multi-controller Aruba deployment, which protocol is used for inter-controller user mobility and session synchronization?
Answer: IAPP / Aruba Mobility Domain (AMR)
Aruba uses IAPP (Inter-Access Point Protocol) within a configured Mobility Domain to synchronize user sessions and enable seamless layer-3 roaming across controllers.
