A. Use ping and the show ip route command to confirm the timers for each default network resets to 0.

B. Load balancing does not occur over default networks; the second route will only be used for failover.

C. Use an extended ping al ong with repeated show ip route commands to confirm the gateway of last resort address toggles back and forth.

Refer to the exhibit. BigBids Incorporated is a worldwide auction provider. The network uses EIGRP as its routing protocol throughout the corporation. The network administrator does not understand the convergence of EIGRP. Using the output of the show ip eigrp topology all - links command, answer the administrator‘s questions.Which three networks is the router at 172.17.10.2 directly connected to?（）

B. 172.17.1.0/24

C. 172.17.2.0/24

D. 172.17.3 .0/25

E. 172.17.3.128/25

A. The default administrative distance has been changed.

B. IS - IS is not enabled.

C. Three physical interfaces are taking part in integrated IS - IS.

D. IS - IS is not redistributing any oth er routing protocols.

E. There are two neighboring routers sending IS - IS routing information.

F. Address summarization is configured.

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.

Refer to the exhibit. A partial routing configuration is shown. Complete the configuration so that only the default - network is redistributed from EIGRP 190 into EIGRP 212. Which ACL statement completes the configuration correctly? （）

A. traffic - share balanced

B. distance

C. maximum- paths

D. default - network

E. variance

Refer to the exhibit. OSPF has been configured on all routers in the network. However, router R1 does not receive a default route to router R2 as in tended. Which configuration change would ensure that R1 would receive a default route from R2? （）

A. Add the area 1 stub command on routers R1.

B. Add the always keyword to the default - information originate configuration command on router R2.

C. Remov e the default information originate configuration command from router R2 and place it on router R1.

A. 1

B. 2

C. 3

D. 4

E. 5

C. Route 6.6.6.0/24 is learned by an IBGP peer.

D. The route 10.10.23.3 is not being advertised to other BGP neighbors.
