Drag and drop the packet types from the left onto the correct descriptions on the right.

Question

Explanation

This question tests your ability to identify and classify the four primary network packet transmission types - unicast, broadcast, multicast, and anycast - by matching each type to its functional description. These are foundational networking concepts frequently tested on CompTIA Network+, CCNA, and similar certifications.

Approach. Match each packet type to its delivery model: Unicast = one source to one specific destination (e.g., a web request); Broadcast = one source to ALL hosts on a subnet (e.g., ARP request, uses 255.255.255.255); Multicast = one source to a subscribed group of receivers (e.g., video streaming, OSPF hellos using 224.x.x.x range); Anycast = one source to the nearest/best single node among a group sharing the same address (used heavily in IPv6 and CDNs/DNS). A fifth type sometimes included is Flood, where a switch sends a frame out all ports except the ingress port when the destination MAC is unknown - this is a switch behavior, not a packet type per se.

Concept tested. Network packet/traffic transmission types: Unicast, Broadcast, Multicast, Anycast - and their delivery scope (one-to-one, one-to-all, one-to-group, one-to-nearest)
