Restore a resilient Layer 2 access block

Diagnose a broken LACP bundle, correct root placement, and recover an edge port without removing loop protection.

Scenario brief

Elm Row Media replaced ACC-2 overnight. Its dual uplink is not forwarding, VLAN 20 elected the access switch as root, and a conference-room port shut down after someone connected a small unmanaged switch. Preserve redundancy and edge protection.

Approved design

list
  • ›Po10 uses LACP on both physical members at both ends.
  • ›DIST-1 is the intended root bridge for VLAN 20.
  • ›User-facing access ports retain PortFast and BPDU Guard.
  • ›The unmanaged switch on Gi1/0/18 will be physically removed before port recovery.

01
matching

Match each symptom to the evidence-backed diagnosis.

3 pts
Need a hint?

Start with the row and choice that have the most distinctive purpose, then use that pair to narrow the rest.

Show another hint

For each remaining pair, explain the relationship in one sentence before selecting it.

02
command

On DIST-1, enter the global command that makes it the primary Rapid PVST+ root for VLAN 20.

3 pts

Whitespace and capitalization are ignored when grading.

Need a hint?

Break the request into three parts: the action, the target, and the required constraint or verification.

Show another hint

Check the tool and subcommand first, then add only the flags, values, and paths the prompt requires.

03
multi select

Select the THREE valid completion checks or recovery actions.

3 pts
Need a hint?

Evaluate each option independently against the scenario evidence instead of treating the list as one decision.

Show another hint

Choose only options that directly satisfy the prompt; being generally true is not enough.
