Nokia 4A0-105 Exam - Topic 5 Question 84 Discussion

Actual exam question for Nokia's 4A0-105 exam

Question #: 84
Topic #: 5

Click on the exhibit below.

Assuming there is a full mesh of mesh-SDPs between the PEs within each metro network and a spoke-SDP between PE-C of Metro A and PE-B of Metro B. how is traffic forwarded from PE-A in Metro A to PE-D of Metro B? Select the most accurate statement.

AAn LSP must be configured between PE-A and PE-D for this traffic to be forwarded.

BA VPLS FDB lookup is done at PE-A of Metro A only

CAn SDP must be configured between PE-A of Metro A and PE-D of Metro D for this traffic to be forwarded

DA VPLS FDB lookup is done at PE-A and PE-C of Metro A and PE-B of Metro B

C sounds wrong too, no SDP needed between those PEs.

B is too limited, it doesn't cover the whole path.

Wait, are we sure about that? Seems a bit complicated.

Definitely not A, you don't need an LSP for that.

I think option D is correct. VPLS FDB lookup happens at all those PEs.

I recall that for traffic to be forwarded correctly, the FDB lookup needs to happen at both ends, so I lean towards option D as well.

I'm a bit uncertain about the need for an LSP. I thought traffic could be forwarded without one if the right SDP is in place.

This question feels familiar; I practiced something similar where we had to determine how traffic flows between different PEs. I think option D might be correct.

I think I remember that VPLS FDB lookups happen at multiple points, but I'm not sure if it's just at PE-A or also at PE-C and PE-B.

I'm a bit confused by the different network elements and their configurations mentioned in this question. I'll need to review the information carefully and try to visualize the network topology to determine the most accurate statement.

Okay, let's see. With the full mesh of mesh-SDPs within each metro network and the spoke-SDP between PE-C and PE-B, I believe the traffic will be forwarded using a VPLS FDB lookup at multiple PEs. I'll double-check my understanding before selecting an answer.

Hmm, this question seems a bit tricky. I'll need to think through the full mesh of mesh-SDPs and the spoke-SDP to determine the correct forwarding behavior.

I think I have a good understanding of how traffic is forwarded in this scenario, but I'll need to carefully read through the details to make sure I select the most accurate statement.

I'm pretty confident about this one. I think the answer is D - they are Turing complete and deterministic in nature.

Okay, I've got this. Performance Based Contracting is all about aligning the vendor's incentives with the client's desired outcomes. So the answer has to be D - it manages the interaction between the two parties.

No problem, I've got this. Key Flexfields have multiple code combinations, and the segments usually contain meaningful information. I'm confident I can nail this question.

I can't recall if we covered these exact scenarios. The idea of the recording server being unavailable makes sense, but it also seems like it could just be a misconfigured trust setup.

D definitely sounds like the correct answer. Forwarding decisions in a VPLS are all about those FDB lookups, like a well-choreographed dance between the PEs. It's like a networking version of the Macarena, but with less hip-shaking and more CLI commands.

I'm going with option D. The question mentions a full mesh and a spoke-SDP, so it's gotta be a VPLS setup. And if you ask me, the FDB lookup is the spice of life when it comes to these networking exams!

Hmm, I was a bit confused at first, but I think D is the way to go. Gotta love those VPLS FDB lookups, am I right? It's like a virtual maze, but with less Minotaurs and more Alcatel-Lucent equipment.

I think the correct answer is D. A VPLS FDB lookup is done at PE-A, PE-C, and PE-B to forward the traffic from PE-A to PE-D. The full mesh of mesh-SDPs and spoke-SDP configuration implies a VPLS setup, and the traffic would need to be looked up in the FDB at multiple PEs.
