Assume all the routes for this prefix have the same attributes.Which three path features would be reasons be for the rou ter to ignore some of the routes and not consider them as candidates for the best path?（）A. paths from an internal BGP (iBGP) neighbor if the local autonomous system (AS) appears in the AS_PATHB. paths for which the NEXT_HOP is inaccess ibleC. paths from an external BGP (eBGP) neighbor if the local autonomous system (AS) appears in the AS_PATHD. paths for which the NEXT_HOP is accessibleE. paths that are marked as synchronized in the show ip bgp outputF. paths that are marked as not synchronized in the show ip bgp output

考题
Which of these best identifies the types of prefixes a router running BGP will advertise to an EBGP peer？ （）A、 prefixes received from any other BGP peer and prefixes locally originated via networkstatements or redistributed to BGPB、 all prefixes in its IP routing tableC、 only prefixes received from EBGP peers and prefixes locally originated via network statements or redistributedD、 only prefixes received from EBGP peers and prefixes received from route reflectorsE、 all prefixes in its routing table except the prefixes received from other EBGP peersF、 all prefixes in its routing table except the prefixes received from other IBGP peers
考题
You have a router running BGP for the MPLS network and OSPF for the local LAN network at the sales office. A route is being learned from the MPLS network that also exists on the OSPF local network. It is important that the router chooses the local LAN route being learned from the downstream switch running OSPF rather than the upstream BGP neighbor. Also， if the local OSPF route goes away， the BGP route needs to be used. What should be configured to make sure that the router will choose the LAN network as the preferred path？（）A、static route needs to be addedB、floating static route needs to be addedC、bgp backdoor commandD、ospf backdoor command
考题
Which two options does Cisco PfR use to control the entrance link selection with inbound optimization？（）A、Prepend extra AS hops to the BGP prefix.B、Advertise more specific BGP prefixes（longer mask）.C、Add（prepend）one or more communities to the prefix that is advertised by BGP.D、Have BGP dampen the prefix.

Router 1 is configured for BGP as dual-homed on the Cisco network. Which three BGP attributes are carried in every BGP update on this router （both IBGP and EBGP）？（）A、originB、router-IDC、AS-pathD、local-preferenceE、next-hop
考题
In which two ways does the BGP graceful capability preserve prefix information during a restart？（）A、The peer router immediately removes the BGP routers that it learned from the restarting router from itsBGP routing tables.B、The router establishes BGP sessions with other routers and relearns the BGP routes from others that are also capable of graceful restart. The restarting router waits to receive updates from the neighboringrouters. When the neighboring routers send end-of-RIB messages to indicate that they are donesending updates，the restarting router starts sending its own updates.C、The peer router sends an end-of-RIB message to the restarting router.D、The restarting router removes any stale prefixes after the timer for stale entries expires.E、The restarting router does not remove any stale prefixes after the timer for stale entries expires.

During BGP configuration on a router that has peered with other BGP speakers, the BGP command aggregate-a ddress 172.32.0.0 255.255.252.0 is issued.
