BBoth detect duplicate IP address assignments.

Show Suggested Answer

Suggested Answer: C

ARP for IPv4 and Neighbor Discovery Protocol (NDP) for IPv6 are both used to map a device's IP address to its MAC address. This is essential for communication within a local network.

ARP is used in IPv4 networks, and NDP performs a similar function in IPv6 networks, ensuring devices can communicate effectively on the same network segment.

I feel like one of the options mentioned duplicate addresses, but I can't recall if that's relevant to ARP or neighbor discovery.

I remember practicing a question similar to this, and I think both ARP and neighbor discovery help in mapping IP addresses to MAC addresses.

I think both protocols are about resolving addresses, but I'm not sure if it's just MAC addresses or IP addresses too.
