Final answer:
Neighbor Solicitation messages in IPv6 are sent as multicast messages to a Solicited Node Multicast Address, not as broadcasts. The correct answer is b. False.
Step-by-step explanation:
The question is asking about Neighbor Solicitation Messages in the context of Internet Protocol version 6 (IPv6). In IPv6, when a device wants to determine the link-layer address of another device on the same network, it sends a Neighbor Solicitation message. This message is not sent as a broadcast, but rather as a multicast to a Solicited Node Multicast Address, which is a specific type of multicast address that corresponds to the target node's IPv6 address.
A broadcast message would be sent to all nodes on the network, but IPv6 uses multicast to be more efficient, sending messages only to a group of interested receivers. Hence, the correct answer to the question is: b. False
