Question 5

Which of the following networking topology requires the MOST physical connectons per node?

A.Bus
B.Ring
C.Star
D.Mesh

Answer: D

In the mesh topology, each node is connected to at least three other nodes. This requires more connectons per node than in the ring or bus topology, in which each node is connected to only two other nodes, or the star topology, in which each node is connected to a central hub or switch.
