  1. What does LLDP (Link Layer Discovery Protocol) help you determine during troubleshooting?

    Answer: Which devices are directly connected to each network port

    LLDP allows network devices to advertise their identity and capabilities to directly connected neighbors, helping map physical network topology.

  2. What is a common cause of wireless clients experiencing slow speeds despite good signal strength?

    Answer: RF interference or co-channel interference from neighboring APs on the same channel

    Co-channel interference from APs operating on the same channel causes contention and retransmissions, degrading throughput even with strong signal.

  3. Which Aruba Central feature helps identify which clients are experiencing poor wireless connectivity?

    Answer: Client Health

    The Client Health feature in Aruba Central shows per-client wireless metrics including signal strength, data rate, and error statistics.

  4. What does MTU mismatch between two network devices cause?

    Answer: Large packets being fragmented or silently dropped, causing application-level failures

    An MTU mismatch causes large packets to be fragmented or dropped by the device with the smaller MTU, often appearing as intermittent application failures.

  5. When an Aruba AP shows as Down in AirWave but is physically powered on, what should you check first?

    Answer: Network connectivity between the AP and the management server (IP, VLAN, firewall rules)

    If an AP is powered but showing down in management, verify IP connectivity and check that no firewall or VLAN misconfiguration blocks management traffic.

  6. What is the purpose of the traceroute command in network troubleshooting?

    Answer: To identify each hop along the path to a destination and measure per-hop latency

    Traceroute sends packets with incrementing TTL values to identify each router hop between source and destination and measure per-hop round-trip times.
