Which of the following answers is most likely to be true, based on thi s output？（）B 128.107.0.0 [20/10] via 11.11.11.11, 00:02:18A. This router has set the Weight of this route to 10.B. This router‘s BGP table lists this route as an iBGP route.C. This router‘s MED has been set to 10.D. This router‘s BGP table lists an AS_Path length of 10 for this route.
A router is running BGP and receives more than one route for a particular prefix. 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

A router has two paths to reach another network in a different autonomous system. Neither route was generated by the local router and both routes have the same default weight an d local preference values.Which statement is true about how BGP would select the best path?（）A. To influence one route to be preferred, its default local preference value will be changed via the use of the command bgp default local - preference 50B. Th e router will prefer the shortest autonomous system pathC. If the command bgp always - compare - med has been given, then the router will prefer the route with the highest MEDD. The router will prefer the route with the lower MED

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
