Selected Answer: C
The protocol responsible for learning an IPv6 neighbor's MAC address is: C. Neighbor Discovery Protocol (NDP) In IPv6, the Neighbor Discovery Protocol (NDP) performs the functionality similar to Address Resolution Protocol (ARP) in IPv4. NDP includes several mechanisms, such as Neighbor Solicitation (NS) and Neighbor Advertisement (NA), to discover and maintain neighbor relationships in an IPv6 network. One of the key functionalities of NDP is the Neighbor Discovery process, which allows a node to determine the link-layer (MAC) address of a neighbor given its IPv6 address. This process is used to populate the neighbor cache with the MAC addresses of neighboring devices in IPv6 networks.

In IPv6, the Neighbor Discovery Protocol (NDP) is responsible for learning a neighbor's MAC address. NDP replaces the Address Resolution Protocol (ARP) used in IPv4 for mapping an IP address to a MAC address.
