Internet access is crucial for the company networ k shown. Internet access is provided by two ISPs. ISP1 is the primary provider a nd ISP2 is the backup provider. The network administrator configures BorderR as the border router so that in normal operations, all Internet traffic goes throug h ISP1. However, if the link to ISP1 fails, then BorderR will automatically forw ard Internet traffic to ISP2. The administrator configures two default routes: B orderR(config)# ip route 0.0.0.0 0.0.0.0 192.168.100.1 200 BorderR(config)# ip r oute 0.0.0.0 0.0.0.0 172.16.1.1 However, when the administrator issued the show ip route command to verify the configuration, only the second default route is i n the routing table. Why is the first default route not showing? The first confi guration command overwrites the second command. The first default route will be installed into the routing table if there is traffic with an IP address that is destined for the 192.168.100.0 network. This is expected because the link to ISP 1 is active. If the link to ISP1 goes down, then the first default route will be installed into the routing table.**** The first default route cannot be install ed into the routing table unless the administrator manually disables the second default route with the no ip route 0.0.0.0 0.0.0.0 172.16.1.1 command. 25 Which command should a network administrator issue to disable default summarization in an EIGRP network? Router(config-router)# null 0 route Router(config-if)# no ip summary-address Router(config-router)# no ip summary-address Router(config-if)# no auto-summary Router(config-router)# no auto-summary**** 26 The headquarters o f a corporation uses static routes to connect to three branch offices. What are two advantages of using static routes for the WAN connections? (Choose two.) Sta tic routes are more secure.**** Static routes converge faster. Static routes hav e higher administrative distances than dynamic routing protocols. The metrics of a static route need adjusting only if the bandwidth of the WAN connection chang es. They are more stable and less susceptible to network changes in the interior gateway protocol.**** 27 What two statements are true regarding EIGRP tables? ( Choose two.) A feasible successor route can be found in the topology table.**** A successor route can only be found in the routing table.
