   • AThe LSA lists the router's directly connected links and their cost, which the receiving router uses in its SPF calculation.
   • BThe LSA provides a summary of routes from other areas.
   • CThe LSA lists all routes in the OSPF domain, including external routes.

   An OSPF neighbor relationship is flapping on a Dell PowerSwitch network. The administrator checks the logs and sees that the neighbor state is going up and down. The hello interval is set to 10 seconds and the dead interval to 40 seconds. What is the most likely cause of the flapping?

   • AThe router ID is not configured, so the router cannot maintain a stable adjacency.
   • BThe hello packets are being dropped intermittently due to network congestion or errors.
   • CThe dead interval is too short, causing the router to declare the neighbor down before receiving the next hello.
   • DThe OSPF process ID is different on the two routers.
