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
Explanation: 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.
