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.
Which of the following three BGP filtering methods enabled with the neighbor command will filter BGP prefixes based on the prefix and prefix length?() A. A neighbor distribute - list out command, referencing a standard ACLB. A neighbor prefix - list out commandC. A neighbor filter - list out commandD. A neighbor distribute - list out command, referencing an extended ACLE. A neighbor route - map out command
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.
Which of the following answers is most true about the BGP Update message?() A. It lists a set of path attributes, along with a list of prefixes that use those PAsB.

A single Update message lists at most a single prefix/lengtH
