Question

What type of traffic always goes to all devices in a subnet?

Answer 1

There are three types of traffic in an IP network:
1. Unicast -  one-to-one traffic (traffic from one sender to one receiver) 
2. Multicast - one to many traffic (one sender and more receivers) 
3.Broadcast -  every device in the network will receive the packet
So, the broadcast traffic always goes to all devices in a subnet.
