Q35. - (Topic 4) 

Refer to the graphic. 

R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem? (Choose two.) 

A. All of the routers need to be configured for backbone Area 1. 

B. R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3. 

C. A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established. 

D. The hello and dead interval timers are not set to the same values on R1 and R3. 

E. EIGRP is also configured on these routers with a lower administrative distance. 

F. R1 and R3 are configured in different areas. 

Answer: D,F

Q38. - (Topic 7) 

Scenario: 

Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links. 

You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the main office and the routers located in the remote branch offices. 

An OSPF neighbor adjacency is not formed between R3 in the main office and R4 in the Branchl office. What is causing the problem? 

A. There is an area ID mismatch. 

B. There is a Layer 2 issue; an encapsulation mismatch on serial links. 

C. There is an OSPF hello and dead interval mismatch. 

D. The R3 router ID is configured on R4. 

Answer: A 


Q39. - (Topic 5) 

Refer to the exhibit. 

What is the cause of the Syslog output messages? 

A. The EIGRP neighbor on Fa0/1 went down due to a failed link. 

B. The EIGRP neighbor connected to Fa0/1 is participating in a different EIGRP process, causing the adjacency to go down. 

C. A shut command was executed on interface Fa0/1, causing the EIGRP adjacency to go down. 

D. Interface Fa0/1 has become error disabled, causing the EIGRP adjacency to go down.
