What is the first step in a systematic network troubleshooting methodology?
Answer: Define the problem and gather information
The first step in systematic troubleshooting is clearly defining the problem by gathering information from users and monitoring systems before taking any action.
Which command on an Aruba switch tests basic IP connectivity to another device?
Answer: ping
The ping command sends ICMP echo requests to test basic IP connectivity and measure round-trip latency to a destination host.
What does a high number of CRC errors on a switch interface typically indicate?
Answer: A physical layer problem such as a bad cable, connector, or duplex mismatch
CRC errors indicate corrupted frames, typically caused by physical layer issues like bad cables, faulty NICs, duplex mismatches, or electrical interference.
What tool would you use to capture and analyze packets on an Aruba network?
Answer: Wireshark with port mirroring
Wireshark combined with port mirroring on the switch captures and analyzes network packets at the interface level for deep troubleshooting.
What does a duplicate IP address conflict cause on a network?
Answer: Intermittent connectivity loss for one or both devices sharing the IP address
Duplicate IP addresses cause intermittent connectivity failures as switches update their ARP tables with conflicting MAC addresses for the same IP.
Which Aruba CLI command shows the MAC address table on a switch?
Answer: show mac-address-table
The show mac-address-table command displays the Layer 2 MAC address table showing which MAC addresses are learned on which switch ports.
