Topic 1 · Question 172

What is the difference between IPv6 unicast and anycast addressing?

AAn individual IPv6 unicast address is supported on a single interface on one node, but an IPv6 anycast address is assigned to a group of interfaces on multiple nodes. (correct answer)
BIPv6 anycast nodes must be explicitly configured to recognize the anycast address, but IPv6 unicast nodes require no special configuration.
CIPv6 unicast nodes must be explicitly configured to recognize the unicast address, but IPv6 anycast nodes require no special configuration.
DUnlike an IPv6 anycast address, an IPv6 unicast address is assigned to a group of interfaces on multiple nodes.

Reveal answer & explanation

Correct answer: A

The correct answer is A. Option A: An individual IPv6 unicast address is supported on a single interface on one node, but an IPv6 anycast address is assigned to a group of interfaces on multiple nodes.

Explanation

OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. IPv6 uses 128-bit addresses and relies on Neighbor Discovery rather than ARP.
