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 Internet - connected router, Ent 1, 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 usefu l for achieving these goals?（）
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.
Router R1 learns two routes with BGP for prefix 200.1.0.0/16. Comparing the two routes, route 1 has a shorter AS_Path Length, smaller MED, the same Weight, and smaller Local PreferencE.

A. Route 1 is the best route.
B. Route 2 is the best route.
C. The routes tie as best, but one will be picked to be placed in the routing table based on tiebreakers .
D. Neither route is considered best.

R1 is currently advertising prefixes 1.0.0.0/8, 2.0.0.0/8, and 3.0.0.0/8 over its eBGP connection to neighbor 2.2.2.2 (R2). An engineer configures a prefix list (fred) on R1 that permits only 2.0.0.0/8 and then enables the filter with the neighbor R2 prefix- list fred out command. Upon exiting configuration mode, the engineer uses some show commands on R1, but no other commands.
Which of the following is true in this case?（）
A. The show ip bgp neighbor 2 .2.2.2 received -routes command lists the three original prefixes.
B. The show ip bgp neighbor 2.2.2.2 advertised - routes command lists the three original prefixes.
C. The show ip bgp neighbor 2.2.2.2 routes command lists the three original prefixes.
D. T he show ip bgp neighbor 2.2.2.2 routes command lists only 2.0.0.0/8.
E. The show ip bgp neighbor 2.2.2.2 advertised - routes command lists only 2.0.0.0/8.

Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a GRE and IPsec tunnel, over the DSL connection, and into the core of an Enterprise network. The branch also allows local hosts to communicate directly with public sites in th e Internet over this same DSL connection.Which of the following answers defines how the branch NAT config avoids performing NAT for the Enterprise directed traffic but does perform NAT for the Internet - directed traffic?（）
