01. Refer to the exhibit. What does the “O*E2″ from the “O*E2 0.0.0.0/0 [110/1] via 192.168.1.1, 00:05:34, Serial0/0″ line represent?
- an internal type 2 OSPF route.
- an external OSPF route at least two hops away.
- an external OSPF route from two different sources.
- an external OSPF route that will not increment in cost.
- a default route.
- The route was distributed into OSPF from a type 2 router.
02. Refer to the exhibit. What is the cost of the route to the 10.0.0.0 network?

- All routes for the entire network will be present.
- Directly connected networks that are operational will be in the routing table.
- Because the SPF algorithm has not completed all calculations, no routes will be in the table.
- A summary route for all previously learned routes will automatically appear in the routing table until all LSPs have been received by the router.

- The number 2 is the autonomous system number.
- The number 2 indicates the number of networks advertised by OSPF.
- The number 2 identifies this particular instance of OSPF on this router.
- The number 2 indicates the priority of the OSPF process on this router.
- Router C cannot win a DR election under any circumstances.
- If the link for interface 192.168.1.4 goes down, router B will become the new DR.
- The highest router ID was most likely determined via an OSPF router-id statement or statements.
- If a new router is added with a higher router ID than router D, it will become the DR.

shut down the loop back interface
use the OSPF router-id 192.168.100.1 command
use the clear ip ospf process command
nothing, the router-id of Router1 is already 192.168.100.1
- A FULL adjacency is formed.
- A 2WAY adjacency is formed.
- Router2 will become the DR and Router1 will become the BDR.
- Both routers will become DROTHERS.
