Regarding a full-mesh network and a partial-mesh network,
what is the most accurate statement?
A. Split Horizon will not work on a full-mesh network
B. A full-mesh network is more expensive because more
routers are used
C. A partial-mesh network is less expensive because less
virtual circuits are used
D. Broadcasts are more plentiful on a partial-mesh network
Answer / guest
Answer: C
A partial-mesh network is less expensive because less
virtual circuits are used. On a full-mesh network, you must
have either a physical or a virtual circuit between all the
nodes. This provides excellent redundancy, but is very costly.
