1

Which of the following topologies required termination?
A. Star
B. Bus
C. Mesh
D. Ring

B. In a bus topology, all computers connected to the network via a main line. The cable had to be terminated at both ends to prevent signal reflection.

2

Star-bus is an example of a ____ topology.
A. transitional
B. system
C. hybrid
D. rampant

C. Star-bus is a hybrid topology because it uses a star physical topology and a bus signal topology.
