What type of information is contained in an ARP table?

  • switch ports associated with destination MAC addresses
  • domain name to IP address mappings
  • routes to reach destination networks
  • IP address to MAC address mappings
    Answers Explanation & Hints:

    ARP tables are used to store mappings of IP addresses to MAC addresses. When a network device needs to forward a packet, the device knows only the IP address. To deliver the packet on an Ethernet network, a MAC address is needed. ARP resolves the MAC address and stores it in an ARP table.
