Examine the exhibit.

Which of the following configuration conditions is required for the proper operation of EVPN VPWS 2?

AThe local AC tag ID configured on PE2 must match the local AC tag ID configured on PEI.

BThe remote AC tag ID configured on PE2 must match the remote AC tag ID configured on PE3.

CThe local AC tag ID and the remote AC tag ID configured on PE2 must match.

DThe local AC tag ID configured on PEI must match the local AC tag ID configured on PE3.

Show Suggested Answer

Suggested Answer: A

The local AC tag ID configured on PE2 must match the local AC tag ID configured on PE1. This ensures that the tag IDs are consistent across both ends of the VPWS service.The remote AC tag ID configured on PE2 does not need to match the remote AC tag ID configured on PE3, as long as they are unique within each PE1.

Haha, you guys are really overthinking this. The answer is clearly option D - the local AC tag ID on PE1 needs to match the local AC tag ID on PE3. That's the only way to ensure the proper operation of EVPN VPWS 2, right?

You know, I was thinking the same thing as Jutta. But then I noticed that the question is asking about 'the proper operation of EVPN VPWS 2', not EVPN VPWS in general. So maybe the local and remote AC tag IDs on PE2 need to match, as in option C?

I'm leaning towards option B. The question specifically asks about the 'proper operation of EVPN VPWS 2', and the remote AC tag ID on PE2 matching the remote AC tag ID on PE3 seems like the most relevant configuration condition for that.

Hmm, I'm not too sure about this. I think the correct answer might be option A, where the local AC tag ID on PE2 needs to match the local AC tag ID on PE1. That seems like the most straightforward requirement.

I agree, this is definitely focused on EVPN VPWS configuration. From the diagram, it looks like we need to match the local and remote AC tag IDs across the different PE devices for the proper operation of EVPN VPWS 2.

I think this question is testing our understanding of EVPN VPWS configuration. The key seems to be understanding the relationship between the local and remote AC tag IDs on the different PE devices.
