Exam 300-135 topic 4 question 1 discussion

Actual exam question from Cisco's 300-135

Question #: 1
Topic #: 4

Scenario:
A customer network engineer has edited their OSPF network configuration and now your customer is experiencing network issues. They have contacted you to resolve the issues and return the network to full functionality.

The OSPF neighbor relationship has been lost between R1 and R3. What is causing this problem?

A. The serial interface in R1 should be taken out of the shutdown state.
B. A neighbor statement needs to be configured in R1 and R3 pointing at each other.
C. The R1 network type should be changed to point-to-multipoint non-broadcast.
D. The hello, dead and wait timers on R1 need to be reconfigured to match the values on R3.

Show Suggested Answer

Suggested Answer: C 🗳️
In order for two OSPF routers to become neighbors, they must have matching network types across the links. In this case, we see that R1 has been configured as non-broadcast and R3 is using point to point non-broadcast.

This can be seen by issuing the "show running-config" command on each router, or the "show ip ospf interface" command:

C is the correct. They ask you what the problem is, not the solution.

B is correct. I make a LAB and I configured R1 to ospf network point-to-multipoint non-broadcast and it does not work. When I configure as neighbor point to each other it works!
