| Question ID 18575 | Refer to the exhibit.
All switches have default bridge priorities, and originate BPDUs with MAC addresses as
indicated. The numbers shown are STP link metrics. Which two ports are forwarding traffic
after STP converges? (Choose two.)
|
| Option A | The port connecting switch SWD with switch SWE
|
| Option B | The port connecting switch SWG with switch SWF
|
| Option C | The port connecting switch SWC with switch SWE
|
| Option D | The port connecting switch SWB with switch SWC
|
| Correct Answer | C,D |
Explanation Explanation: Here, we know SWB to SWC are forwarding because we already identified the blocking port. So for the last correct answer lets consider what must be done to prevent a switch loop between SWC/SWD/SWE. SWE to SWD will be blocked because SWC has a lower MAC address so it wins the forwarding port. And to look at it further, you could try to further understand what would happen with ports on SWG. Would the ports on SWG try to go through SWE or SWF? SWE has the lower MAC address so the port from SWG to SWE would win the forwarding election. Therefore, answer B could never be correct.
