Two routers named Atlanta and Brevard are connected via their serial interfaces as illustrated, but
they are unable to communicate. The Atlanta router is known to have the correct configuration.

Given the partial configurations, identify the fault on the Brevard router that is causing the lack of
connectivity.

A.
incompatible IP address

B.
insufficient bandwidth

C.
incorrect subnet mask

D.
incompatible encapsulation

E.
link reliability too low

F.
IPCP closed

Explanation:
The correct explanation should be that the Atlanta router is usng HDLC while the Brevard is using
PPP. These need to match on both ends.
