E. run RIP only
Ans A,B &C
An autonomous system is a set of routers and
networks under the same administration. Each router must be
interconnected, run the same routing protocol, and assigned
the same autonomous system number. The network Information
Center (NIC) assigns a unique autonomous system number to
enterprises.
30 A default route is analogous to a _________.
A. default gateway
B. static route
C. dynamic route
D. one-way route
Ans: A
A default route is analogous to a default
gateway. It is used to reduce the length of routing tables
