Which command displays the IP-to-MAC address mappings stored in the ARP cache?

• A. Arp
• B. Netstat
• C. Nslookup
• D. Ipconfig

Answer: (A)

Viewing the ARP cache reveals the IP-to-MAC mappings the host has learned on the local network. The ARP protocol translates IP addresses to MAC addresses, and the ARP cache stores these mappings to speed up communication with local devices. The ARP command displays this cache, typically listing each IP alongside its corresponding MAC address. The other commands serve different purposes: Netstat shows active connections and ports, Nslookup queries DNS for domain name resolution, and Ipconfig shows your device’s IP configuration rather than the local ARP mappings.
