Nokia 4A0-105 Exam - Topic 7 Question 83 Discussion

Click on the exhibit below.In the following diagram, traffic ingressing on SAP 1/2/3:1 will be passed to the layer-2 DPI device for inspection based on a filter policy applied to the ingress of the SAP. What feature should be enabled on SAP 1/2/1:100 and SAP 1/2/2:100 to ensure that incorrect information is not populated in the FDB of VPLS 1?
D) The SAPs connected to the DPI should be configured with the 'discard-unknown' feature to limit MAC learning on the port
A) Learning should be disabled on both SAPs connected to the DPI device to prevent FDB instability
B) A MAC filter should be applied to both SAPs connected to the DPI to limit MAC learning on the port
C) An IP filter should be applied to both SAPs connected to the DPI to prevent FDB instability

Not sure about that, seems risky to disable learning completely.

I’m leaning towards the MAC filter option, but I’m a bit confused about whether an IP filter could also work in this scenario.

I feel like using the 'discard-unknown' feature was mentioned in our study materials, but I can't recall the exact context.

I think we practiced a similar question where applying a MAC filter helped limit learning. That might be relevant for this one too.

I remember something about disabling learning to avoid FDB issues, but I'm not sure if that's the best approach here.

The question mentions a filter policy on the ingress of the SAP, so maybe we need to apply a specific type of filter to the other SAPs to prevent FDB issues.

I think the answer is to disable learning on the SAPs connected to the DPI device, but I'm not 100% certain that's the right approach.

Okay, let me think this through. The traffic is ingressing on SAP 1/2/3:1 and going to a DPI device, so we need to prevent incorrect information from populating the FDB of VPLS 1.

Okay, let me see here. I know TMMi provides a framework for test process improvement, but I can't quite recall the details about the maturity levels and architecture. I'll have to read through the options closely.

Hmm, I'm a little unsure about the difference between "Professional and consultant services" and "Transportation term contracts." I'll need to review my notes to make sure I understand the precise definitions.

I'm torn between B and D. Both seem to address the issue of MAC learning, but D seems more specific to the task at hand. Maybe I should just roll a dice and hope for the best!

I think the correct answer is D. Enabling the 'discard-unknown' feature on the SAPs connected to the DPI device will prevent unknown MAC addresses from being learned and added to the FDB, which helps maintain FDB stability.
