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.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.
Router R1 sits inside OSPF area 1. Router R2 redistributes an E1 route into OSPF for prefix 2.2.2.0/24, with external metric 20. Router R22 redistributes an E2 route for the same prefix/length, external metric 10.Under what conditions will R1 choose as it s best route the route through R22?（）A. R1 will always choose the route through R22.B. As long as R1‘s best internal OSPF cost to reach R22 is less than 10.C. As long as R1‘s best internal OSPF cost to reach R22 is less than 20.D. R1 will never choo se the route through R22 if the E1 route through R2 is available.
Refer to the above exhibit. Why is the 140.140.0.0 network not used as the gateway of last resort even though it is configured first?() A.The last default - network statement will always be preferred.B.A route to the 140.140.0.0 network does not exist in the routing table.C.Default - network selection will always prefer the statement with the lowest IP address.D.A router will load balance across multiple default - networks; repeatedly issuing the show ip route command would show the gateway of last resort changing between the two networks.
You have just configured a static default route on router TK1. What is the purpose of a default route?() A. It is a route to be used when the routing protocol fails.B.

It is a route manually configured for a specific remote network for which a routing protocol is not configured.E. It is used to send traffic to a stub network.
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
