A network engineer is troubleshooting a connectivity issue. A host has the IPv6 address fe80::1/64 and is unable to reach a server at 2001:db8::1/64. What is the most likely reason?

The host's prefix length is /64, which is too short for routing.

The host's address is a unique local address.

The host only has a link-local address, which is not routable beyond the local link.

The server's address is a multicast address.

A network administrator is reviewing a packet capture and sees the destination address ff02::1:ff00:1234. What is the purpose of this address?

It is an anycast address used for load balancing

It is a solicited-node multicast address used for duplicate address detection

It is a global multicast address used for internet-wide communication

It is a link-local unicast address used for local communication
