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?
Explanation
Correct Answer
For West Auditorium, the decisive mechanism is BPDU guard edge ports. BPDU guard protects edge ports from becoming transit paths for unauthorized switches. Confirm a test BPDU causes edge protection without disabling authorized trunks supplies measurable, case-relevant evidence that the intended behavior actually occurs.
Incorrect Answers
This is relevant to Voice VLAN LLDP-MED, where lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bPDU guard protects edge ports from becoming transit paths for unauthorized switches
This is relevant to End-to-end MTU and frames, where a path's effective MTU is limited by the smallest supported segment and encapsulation overhead In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bPDU guard protects edge ports from becoming transit paths for unauthorized switches
This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the West Auditorium case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is bPDU guard protects edge ports from becoming transit paths for unauthorized switches
