Question 130
At Central Hall, a new campus fiber uplink should be preferred but interface costs retain old values. Which configuration change best fits the network requirement and observed behavior?
Explanation
Correct Answer
For Central Hall, the decisive mechanism is OSPF metric selection. OSPF chooses shortest paths based on cumulative advertised link cost. Set intentional OSPF interface cost reflecting primary and backup path design establishes the needed configuration in the case rather than merely measuring a symptom.
Incorrect Answers
This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost
This is relevant to DHCP relay return routing, where dHCP relay requires a valid return path to the relay address and client network In the Central Hall case, Changing that neighboring feature does not implement the missing function. 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 Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost
