Question

A single switch has 8 hosts directly connected to 8 of its ports, and one additional port connects to an old hub that itself connects 4 more hosts. No router is present anywhere in this network. How many collision domains and broadcast domains exist in total?

Every switch port is its own collision domain, so the 8 directly-connected hosts give 8 separate collision domains the hubs port counts as one more collision domain shared by its 4 hosts hubs do not separate collisions, giving 8 collision domains total. Since there is no router to separate broadcast traffic, the entire network remains a single broadcast domain.
