How does ARP translate logical addresses?

The correct answer is C. IPv4 to MAC addresses. The Address Resolution Protocol (ARP) translates an IPv4 logical address into a physical MAC address to enable communication on a local network segment.

Why each option

The Address Resolution Protocol (ARP) translates an IPv4 logical address into a physical MAC address to enable communication on a local network segment.

AIPv6 to IPv4 logical addresses

ARP does not translate between IPv6 and IPv4 addresses; that would typically involve a gateway or translation mechanism.

BIPv4 to IPv6 logical addresses

ARP does not translate between IPv4 and IPv6 addresses.

CIPv4 to MAC addressesCorrect

ARP is specifically designed to resolve IPv4 addresses to corresponding MAC addresses. This allows devices to find the hardware address of another device on the same local network when only its IP address is known, facilitating frame delivery at the data link layer.

DIPv6 s to MAC addresses

Neighbor Discovery Protocol (NDP) is the protocol used in IPv6 for resolving IPv6 addresses to MAC addresses, not ARP.
