Comparing the two routes, route 1 has a shorter AS_Path Length, smaller MED, the same Weight, and smaller Local PreferencE.Which of the following is true about Router R1‘s choice of best path for this prefix?（）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.
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
