Discuss Nokia 4A0-115 Exam Topic 10 Question 13

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?

APEI

BPE2

CPE3

DPE4

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.

Just checked, PE2 is definitely the right choice!

Sheron 11 months ago

I thought PE4 had a better EVI score?

Linwood 11 months ago

Wait, are we sure it's not PE3?

Rory 11 months ago

Totally agree, PE2 makes sense here!

Lashawn 12 months ago

PE2 is the DF for VPLS 10.

Makeda 12 months ago

I’m leaning towards PE3, but I really need to double-check how the algorithm works with the EVI ranges.

Theola 1 year ago

I think I recall that the lowest EVI value gets priority, but I could be mixing it up with another concept.

Rodolfo 1 year ago

This question feels similar to one we practiced where we had to determine the DF based on EVI settings. I think PE2 might be the right choice.

Nu 1 year ago

I remember studying the preference-based algorithm, but I'm not entirely sure how it applies to the EVI range in this scenario.

Hannah 1 year ago

I've got a good handle on VPLS and DF election. Based on the information provided in the exhibit, I believe the answer is PE2, as it likely has the highest preference value among the PEs.

Crista 1 year ago

This is a tricky one. I'm not entirely confident in my understanding of the preference-based DF election process. I'll need to carefully read through the question and the exhibit, and maybe even refer to my study materials, to make sure I'm approaching this correctly.

Elliot 1 year ago

Okay, I think I've got this. The question states that the preference-based algorithm is used to elect the DF on ESI 1. So I'll need to look at the preferences of the PEs and determine which one has the highest preference and is therefore elected as the DF for VPLS 10.

Jennie 1 year ago

Hmm, I'm a bit unsure about this one. The exhibit shows an EVI range configuration, but I'm not sure how that relates to the DF election process. I'll need to review my notes on VPLS and preference-based DF election.

Lisha 1 year ago

This looks like a straightforward VPLS question. I'll need to carefully analyze the information provided in the exhibit to determine which PE is elected as the DF.

Helga 1 year ago

This seems pretty straightforward. I think the answer is B - First decision that matches.

Marquetta 1 year ago

This seems like a straightforward question about the reasons for choosing a scrip dividend. I'll need to carefully consider the options and think about the company's situation.

Nana 1 year ago

Okay, the key seems to be ensuring there's enough available space in the right locations. I'm thinking options C and E are the way to go here.

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

Lai 1 year ago

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.

Maira 1 year ago

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.

Malcom 1 year ago

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.

Diane 1 year ago

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.

PE2 stands out as the designated forwarder for VPLS 10.

Theodora 1 year ago

↳ replying to Diane

PE2 is definitely the right choice based on the exhibit.

Yaeko 1 year ago

↳ replying to Diane

That's correct, PE2 is the designated forwarder based on the configuration provided in the exhibit.

Dortha 1 year ago

↳ replying to Diane

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

Dana 1 year ago

That makes sense, PE2 has the highest priority in the configuration.

Sabrina 1 year ago

I agree, the preference-based algorithm would choose PE2 as the designated forwarder for VPLS 10.

I'm not sure, but I think PE4 might be the one elected as DF.

I believe it's PE2 because of the preference-based algorithm.
