Question

Which are outputs for the command `diagnose hardware deviceinfo nic'? (Choose two.)

Options

  • AARP cache
  • BPhysical MAC address
  • CErrors and collisions
  • DListening TCP ports

Explanation

The FortiGate command diagnose hardware deviceinfo nic provides hardware-level network interface card (NIC) details, including its physical MAC address and error/collision statistics.

Common mistakes.

  • A. The ARP cache, which maps IP addresses to MAC addresses, is a network layer function and is viewed using commands like get system arp or diagnose ip arp list, not a direct hardware attribute reported by deviceinfo nic.
  • D. Listening TCP ports indicate services and applications running on the FortiGate's operating system, not a hardware characteristic of the NIC itself; this information is typically retrieved using fnsysctl netstat -apn.
