Question 720

At West Auditorium, an employee connects a small unmanaged switch that sends BPDUs into an edge access port. What measured or witnessed result should be required before signoff?

  1. Verify the phone uses the voice VLAN while the PC remains in the data VLAN.
  2. Run controlled large-payload tests and confirm reliable path MTU behavior.
  3. Permit a specifically authorized app and block the matching forbidden traffic.
  4. Confirm a test BPDU causes edge protection without disabling authorized trunks.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is BPDU guard edge ports. BPDU guard protects edge ports from becoming transit paths for unauthorized switches.
