Question 230
At a design studio in Berlin, engineers report that an SVI stays down because the associated VLAN lacks any active eligible member port. The work affects wireless workstations and video conferences. Which post-change observation is the strongest acceptance evidence?
Explanation
Correct Answer
This observation tests the SVI gateway and inter-VLAN reachability requirement at a design studio in Berlin. The expected result is that clients in each subnet reach their local gateway and only the authorized inter-VLAN flows succeed. The necessary correction is to create and validate the SVI on the correct VLAN with appropriate IP addressing, routing and permitted cross-VLAN policy; a saved configuration alone would not prove it is working. In this case, the observed fault is that an SVI stays down because the associated VLAN lacks any active eligible member port.
Incorrect Answers
At a design studio in Berlin, this would verify Layer-two edge protection and BPDU controls, not the failure reported in this scenario. The requested closure criterion instead concerns SVI gateway and inter-VLAN reachability: clients in each subnet reach their local gateway and only the authorized inter-VLAN flows succeed.
At a design studio in Berlin, the observation may be useful for a separate Ingress ACL enforcement and least privilege test, but it does not establish that an SVI stays down because the associated VLAN lacks any active eligible member port has been resolved. The relevant check is the SVI gateway and inter-VLAN reachability outcome.
At a design studio in Berlin, this would verify RSTP root election and loop prevention, not the failure reported in this scenario. The requested closure criterion instead concerns SVI gateway and inter-VLAN reachability: clients in each subnet reach their local gateway and only the authorized inter-VLAN flows succeed.
