In which of the following network configurations would
problem resolution be the easiest?
A. Bus
B. Ring
C.Star
D. Mesh
Answer / guest
Answer: C
The star configuration would be the easiest network for
problem resolution. In a star configuration all lines are
connected to the central hub. A problem can occur if the
central hub fails. A bus configuration can be difficult to
troubleshoot since a cable break can be difficult to find.
Ring configurations are also difficult to trouble shoot.
Problems in a mesh configuration are also easy to diagnose,
but not as easy as in a star configuration.
