Click the Exhibit button. Referring to the exhibit, which statement is true?
- A. R3 and R4 have an adjacency state of Full.
- B. R1 and R2 are elected as DROTHERs.
- C. R3 has the complete OSPF database.
- D. R4 is elected as the DR.
Answer: C,D
Explanation:
C: In LANs, the election of the designated router takes place when the OSPF network is initially established. When the first OSPF links are active, the routing device with the highest router identifier (defined by the router-id configuration value, which is typically the IP address of the routing device, or the loopback address) is elected the designated router.

- C. Link-state request
- D. Database description
Answer: C

- A. Configure static routes to the tunnel endpoints.
- B. Configure OSPF to not export the tunnel endpoint interface routes.
- C. Configure the physical WAN interfaces on both routers as passive OSPF interfaces.
