  1. What does a spanning-tree topology change notification indicate on an Aruba switch?

    Answer: A port state change that may temporarily disrupt traffic and trigger MAC address table flushes

    A spanning tree topology change causes switches to flush their MAC address tables and temporarily flood traffic until the table is rebuilt.

  2. Which Aruba diagnostic tool performs active tests simulating real user traffic to measure network performance?

    Answer: Aruba Central Network Tests

    Aruba Central Network Tests perform synthetic active measurements simulating real user traffic to identify performance degradation proactively.

  3. What is the most likely cause when a DHCP client cannot obtain an IP address?

    Answer: DHCP server unreachable, scope exhaustion, or missing DHCP helper-address on the router

    DHCP failures are typically caused by the DHCP server being unreachable, the IP scope being exhausted, or a missing relay agent on the router.

  4. What does 'flapping' mean in the context of network interfaces or routing protocol neighbors?

    Answer: A port or neighbor repeatedly going up and down in rapid succession

    Flapping describes an interface, link, or routing neighbor that repeatedly cycles between up and down states, causing instability and repeated reconvergence.

  5. What information does the show ap debug client-table command provide on an Aruba controller?

    Answer: Per-client association details including signal, data rate, and authentication state

    The show ap debug client-table command on an Aruba controller displays per-client details including signal strength, transmit/receive rates, and authentication state.

  6. What Aruba tool would you use to visualize the RF environment and identify coverage gaps?

    Answer: Aruba Central RF Health or Aruba AirWave VisualRF

    Aruba Central RF Health and AirWave VisualRF provide floor plan-based RF visualization to identify coverage gaps, interference, and channel planning issues.
