Cisco Certified Network Associate (CCNA) 200-301 — Question 172

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.
