Which network traffic type is sent to all nodes on a network?
Which of the following network traffic types is sent to all nodes on the network?

100% of anonymous learners picked answer B. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The exam tests your ability to distinguish one-to-all broadcast from one-to-group multicast; many candidates confuse multicast with broadcast because both send to multiple receivers, but multicast only reaches subscribed devices.
Broadcast traffic is the network transmission type sent to all nodes on a network segment. Community consensus strongly confirms that unicast, multicast, and anycast do not reach every node, making broadcast the correct answer.
Choosing multicast is the most common mistake: multicast sends to a specific group of subscribed hosts, whereas a broadcast is forwarded to every node on the broadcast domain, regardless of group membership.

Expert Analysis
Why the Answer Is Correct
Broadcast traffic is explicitly defined as one-to-all communication. When a frame or packet is sent to the broadcast address (e.g., MAC FF:FF:FF:FF:FF:FF or IP 255.255.255.255), it is delivered to every node on the same network segment or broadcast domain. This matches the wording of the question exactly.
Community comments confirm this understanding: comment [2] states, 'Broadcast traffic is sent to all nodes on the network. When a device sends a broadcast message, it is delivered to every other device on the same network segment or broadcast domain.' Comment [1] simply and correctly names B. Broadcast.
Why the Other Options Are Wrong
Unicast is one-to-one communication, where a single packet is sent from one source to a single destination host. Anycast is one-to-nearest, delivering to the nearest of a set of receivers. Both obviously fail the 'all nodes' condition.
Multicast is the closest distractor because it reaches multiple hosts, but it only reaches a subscribed group, not all nodes. Only broadcast is destined for every node on the network segment.
Community Comment Notes
No comments in the provided list support any answer other than B; all three useful comments agree on broadcast. The lower-ranked comment [3] also references the concept of a broadcast domain, which is an important qualifier because broadcasts are not typically forwarded across routers.
The key takeaway from the comments is that 'broadcast' is short for 'broadcast domain-wide delivery,' and that is exactly what the question asks.

Exam Strategy
Memorize the four transmission types by their one-to-X mappings: unicast = one-to-one, multicast = one-to-many (group), broadcast = one-to-all, anycast = one-to-nearest. On the exam, if a question says 'sent to all nodes,' always choose broadcast without being tempted by multicast.
