單項選擇題 Refer to the exhibit. A Boston company bought th e assets of a New York company and is trying to route traffic between the two data networks using EIGRP. The show command output shows that traffic will not flow between the networks. As a network consultant, you were asked to modify the configuration a nd certify the interoperability of the two networks. For traffic to flow from subnet 172.16.8.0/24 to the 172.16.16.0/24 subnet, which configuration change do you recommend?（）

A. Turn off autosummarization on routers N1 and B1.
B. Add IP summary addre sses to the Internet - pointing interfaces of routers N1 and B1.
C. Turn off autosummarization on routers N2 and B2.
D. Add wildcard masks to the network commands on routers N2 and B2.

2.單項選擇題 Refer to the exhibit.The actual speed of the serial links between R2 and R3 are 256 kb/s and 512k b/s respectively. When configuring EIGRP on routers R2 and R3, the network administrator configured the bandwidth of both serial interfaces to 512 kb/s. What will be the effect?（）

A. EIGRP will overutilize the 512 kb/s link.
B. The interface "delay" value used in the EIGRP metric calculation will be inaccurate on the 256k b/s serial interface.
C. The amount of bandwidth used for EIGRP routing protocol traffic on the 256 kb/s link can become excessive.
D. EIGRP can load balance between the two serial links only if the variance is set to 2 or higher.
E. Unequal cost load balancing will be disabled.

4.單項選擇題 Refer to the exhibit. The Route.com company is running EIGRP between all the r outers. Currently, if one of the LAN links (LAN1 or LAN2) at the headquarters flaps (goes up and down), the HQRTR1 and HQ - RTR2 routers will experience high CPU usage and have a long EIGRP convergence time. As the new network administrator, you are asked to investigate this situation and determine if there is a quick way to resolve this issue. Which is the most important thing that you can quickly verify first to resolve this issue?（）

A. Verify that the bandwidth setting on all WAN links is correct.
B. Verify that the HQ - RTR1 and HQ - RTR2 routers are configured to send only a default route to all the spoke routers.
C. Verify that the HQ - RTR1 and HQ - RTR2 routers are configured for EIGRP Nonstop Forwarding.
D. Verify that all the spoke routers are co nfigured for autosummarization.
E. Verify that all the spoke routers are configured as EIGRP stub.
