Question 550
During a planned campus-network change at a university faculty building in Boston, operators discover that the same physical link has peers configured for conflicting OSPF area identifiers. The design must preserve teaching tools and shared printers. Which test result most directly confirms the required behavior?
Explanation
Correct Answer
This observation tests the OSPF neighbor prerequisites and states requirement at a university faculty building in Boston. The expected result is that the expected neighbor reaches the required state and the authorized OSPF routes enter the routing table. The necessary correction is to align OSPF participation, area, reachability and neighbor authentication before troubleshooting downstream learned routes; a saved configuration alone would not prove it is working. In this case, the observed fault is that the same physical link has peers configured for conflicting OSPF area identifiers.
Incorrect Answers
At a university faculty building in Boston, this would verify VRF segmentation and routing isolation, not the failure reported in this scenario. The requested closure criterion instead concerns OSPF neighbor prerequisites and states: the expected neighbor reaches the required state and the authorized OSPF routes enter the routing table.
At a university faculty building in Boston, this measures a different network requirement, OSPF path metric and convergence. The case describes that the same physical link has peers configured for conflicting OSPF area identifiers, so accepting this result would leave the primary fault without direct verification.
At a university faculty building in Boston, this would verify Dynamic route filtering and redistribution, not the failure reported in this scenario. The requested closure criterion instead concerns OSPF neighbor prerequisites and states: the expected neighbor reaches the required state and the authorized OSPF routes enter the routing table.
