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.
