Which three technologies can be used to implement redundancy for IPv6? (Choose three)

IPv6 Neighbor Advertisement (NA) is part of Neighbor Discovery Protocol (NDP) for address resolution and reachability, not for first-hop redundancy.

NHRP (Next Hop Resolution Protocol) is used in NBMA networks for address mapping and next-hop resolution, not as a first-hop redundancy protocol.

HSRP (Hot Standby Router Protocol) supports IPv6, allowing multiple routers to share a virtual IPv6 address and MAC address for first-hop redundancy.

DVMRP (Distance Vector Multicast Routing Protocol) is an older multicast routing protocol and not a first-hop redundancy protocol for unicast IPv6 traffic.

GLBP (Gateway Load Balancing Protocol) also supports IPv6, providing first-hop redundancy with load balancing across multiple routers using a single virtual IPv6 address and multiple virtual MAC addresses.

IPv6 Router Advertisements (RAs) can be used by routers to advertise multiple default gateways to hosts, enabling hosts to learn and use alternative routers for redundancy in case of a primary router failure.
