Actual exam question for Nokia's 4A0-115 exam
Question #: 13
Topic #: 10
[All 4A0-115 Questions]

In the exhibit, an EVI range is configured and the preference-based algorithm is used to elect the designated forwarder (DF) on ESI 1. Which PE is elected as DF for VPLS 10?

Show Suggested Answer Hide 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.

Wait, so we're electing a designated forwarder for a VPLS? Is that like a designated driver for a virtual pub crawl?

Wow, this is a tough one. I feel like I'm playing 'Where's Waldo' trying to figure out which PE is the DF. I'm gonna go with my gut and say C) PE3, but I'm not 100% confident in that answer.

Ha, this question is a real brain-teaser! I bet the exam writers get a kick out of tripping us up with these kinds of technical details. Anyway, I'm going with B) PE2 – it just makes the most sense to me.

I'm a bit confused by the question. What's an EVI range, and how does it relate to the DF election process? I'm going to have to re-read the study materials on this topic.

Based on the exhibit, I think the answer is B) PE2. The preference-based algorithm would elect the PE with the highest priority, which is PE2 according to the configuration shown.

Yes, PE2 has the highest priority in the EVI range configuration, so it makes sense that it would be elected as the DF.
