Question 190
At a design studio in Berlin, engineers report that an engineer mistakes routing ECMP for a replacement of host first-hop redundancy. The work affects wireless workstations and video conferences. Which test result most directly confirms the required behavior?
Explanation
Correct Answer
This observation tests the First-hop gateway redundancy and failover requirement at a design studio in Berlin. The expected result is that hosts retain the intended gateway identity and route through an available peer when the active first-hop device is lost. The necessary correction is to configure and verify a supported first-hop redundancy mechanism with correct virtual gateway address and ownership; a saved configuration alone would not prove it is working. In this case, the observed fault is that an engineer mistakes routing ECMP for a replacement of host first-hop redundancy.
Incorrect Answers
At a design studio in Berlin, this would verify Multi-chassis LAGs and active paths, not the failure reported in this scenario. The requested closure criterion instead concerns First-hop gateway redundancy and failover: hosts retain the intended gateway identity and route through an available peer when the active first-hop device is lost.
At a design studio in Berlin, the observation may be useful for a separate VSF member roles and stack consistency test, but it does not establish that an engineer mistakes routing ECMP for a replacement of host first-hop redundancy has been resolved. The relevant check is the First-hop gateway redundancy and failover outcome.
At a design studio in Berlin, this measures a different network requirement, VSX inter-switch link and keepalive. The case describes that an engineer mistakes routing ECMP for a replacement of host first-hop redundancy, so accepting this result would leave the primary fault without direct verification.
