Question 690
At West Auditorium, traffic uses the slow uplink because OSPF cost is unexpectedly lower there. What observable outcome would prove this repair actually works?
Explanation
Correct Answer
For West Auditorium, the decisive mechanism is OSPF metric selection. OSPF chooses shortest paths based on cumulative advertised link cost. Test traffic uses the intended lowest-cost path and fails over appropriately supplies measurable, case-relevant evidence that the intended behavior actually occurs.
Incorrect Answers
This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost
This is relevant to Static route next hop, where a static route only forwards as intended when its next hop can be resolved In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost
This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost
