Click the Exhibit button.Referring to the exhibit, why are the OSPF routes missing from the routing table for this router?
A.mismatching OSPF interface type with the neighbor
B.MTU mismatch with the neighbor
C.incorrect IP address configured on the interface
D.no Type 4 LSAs in the OSPF database
Answer: A
Question: 3
Click the Exhibit button.
Referring to the exhibit, you are configuring an OSPF network. All OSPF adjacencies come up and stay stable. But neither R1 nor R2 has the prefix 200.200.200.200/32 in its routing table.
What is causing this problem?
A.R2 does not have the export policy for prefix 200.200.200.200/32.
B.R1 does not have routes to network 172.10.1.0/24.
C.R2 is BDR on both network 172.10.1.0/24 and 172.20.1.0/24.
D.The router ID of R1 is the same as the router ID of R3.
Answer: D
Question: 4
Click the Exhibit button.
You are troubleshooting an OSPF adjacency problem between R1 and R2.
Referring to the exhibit, what is causing this OSPF adjacency problem?
A.There is a hello interval mismatch.
B.There is a dead interval mismatch.
C.There is an MTU mismatch.
D.There is an LSA refresh timer mismatch.
Answer: C
Question: 5
Click the Exhibit button.
You notice that there is a problem with the OSPF adjacency between two routers, R1 and R2. The relevant system logs from R1 are shown in the exhibit.What would cause this behavior?
A.R2 was dropping R1's OSPF hello packets.
B.R1 was dropping R2's OSPF hello packets.
C.R1's interface went down and came back up.
D.There is an OSPF hello timer mismatch between the two routers.
