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

Learning should definitely be disabled on those SAPs.

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.

Hmm, I'm leaning towards the "discard-unknown" feature, but I want to double-check that against the other options to make sure I'm not missing something.

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!

A seems like a reasonable option, but disabling learning completely might be a bit overkill. D sounds like a more targeted approach to the problem.

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.
