Which IPV6 function serves the same purpose as ARP entry verification on an IPv4 network?
Click on the arrows to vote for the correct answerA. B. C. D.
The correct answer is C. neighbor discovery verification.
In IPv4, Address Resolution Protocol (ARP) is used to map a known IP address to an unknown MAC address. ARP entry verification helps to ensure that the correct MAC address is associated with a particular IP address in the ARP cache.
In IPv6, neighbor discovery serves the same purpose as ARP in IPv4. Neighbor discovery protocol (NDP) is used to map a known IPv6 address to a corresponding link-layer (MAC) address.
Therefore, neighbor discovery verification is the equivalent of ARP entry verification in IPv4 networks. It ensures that the correct MAC address is associated with a particular IPv6 address in the neighbor cache.
Option A, interface IP address verification, is used to verify the configuration of IPv4 or IPv6 addresses assigned to an interface, but it does not verify the MAC address associated with an IP address.
Option B, MAC address table verification, is used to verify the contents of the MAC address table in a switch, which contains information about the MAC addresses of devices connected to each port. However, this is not related to ARP or neighbor discovery.
Option D, Routing table entry verification, is used to verify the routing table entries that are used to determine the next hop for packets to be forwarded, but it is not related to ARP or neighbor discovery.
