A network engineer sees traffic going to 224.

The answer is C. Multicast . The address 224.7.8.99 falls within the IPv4 Class D range, which is 224.0.0.0 through 239.255.255.255 . That range is reserved for multicast traffic. Multicast is used when one sender needs to deliver traffic to a specific group of receivers rather than to every device on the network or to just one destination.

That is what separates it from the other choices. Broadcast is intended for all hosts on the local broadcast domain. Unicast is one-to-one communication, where a single source sends traffic to one specific destination. Anycast is typically associated with sending traffic to the nearest or best member of a group that shares the same address, not to a multicast group address in the 224.0.0.0/4 range.

From a Network+ point of view, this is a basic address-recognition question. Once you recognize that the destination begins with 224 , the answer should immediately point to multicast. Protocols and streaming applications often use multicast when they need efficient delivery to multiple interested hosts without flooding every device. So in this case, the traffic type is clearly multicast .
