Cisco Certified Network Associate (CCNA) 200-301 — Question 1222

The correct answer is B. Option B: A packet sent to an IPv6 multicast address is delivered to one or more destinations at once, but a packet sent to an IPv6 anycast address is routed to the closest interface with that address.

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. NAT translates addresses between network domains, commonly conserving public IPv4 addresses.
