Which of the following is the primary motivation for using BGP between an Enterprise and its
ISPs?

A.
To influence the choice of best path (best route) for at least some routes

B.
To avoid having to configure static routes

C.
To allow redistribution of BGP routes into the IGP routing protocol

D.
To monitor the size of the Internet BGP table

Explanation:
Although using BGP does avoid some static configuration at the Enterprise and the ISP, the
primary reason to consider using BGP in the Enterprise is to influence and react to Path
Attributes for the purpose of choosing the best patH. Typically, engineers do not redistribute

BGP routes into the IGP due to scalability problems. And although it may be interesting to
monitor the size of the Internet BGP table, it is not a primary motivation for choosing to use
BGP on a router.
