Which of the following answers lists a configuration step that would not be useful for achieving these goals?

An engineer has been told to create an implementation plan to influence the choice of best
BGP route on a single router using the Weight featurE. The sole Enterprise Internetconnected router, Ent1, has neighbor relationships with Routers ISP1 and ISP2, which
reside inside two different ISPs. The goal is to prefer all routes learned from ISP1 over ISP2
using Weight. Which of the following answers lists a configuration step that would not be
useful for achieving these goals? (Choose two.)

A.
Configuring the neighbor weight command on Ent1.

B.
Having the ISPs configure the neighbor route-map out command on ISP1 and ISP2, with
the route map setting weight.

C.
Configuring the set weight command inside a route map on Router Ent1.

D.
Configuring a prefix list to match all class C networks.

Explanation:
Weight, a Cisco-proprietary feature of BGP on Cisco routers, cannot be transmitted in a BGP
Update, so setting Weight on an outbound route map at the ISPs will have no effect. Also,
the goals call for setting Weight for all routes from an ISP to the same number, so creating a
prefix list to match a subset of reachable prefixes, in this case all class C networks, is not

useful. However, two methods of configuring Weight do exist: the neighbor weight command
and configuring an inbound route map with a set weight command in the route map.
