Wow, this question really separates the network engineers from the network ninjas. If you can't figure this one out, you might as well just become a professional couch surfer.

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!

Yeah, I agree. B is more about limiting MAC addresses in general, while D is focused on preventing incorrect information in the FDB.

I think D is the better option here. It specifically mentions limiting MAC learning on the port.

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.

But wouldn't disabling learning on the SAPs prevent FDB instability?

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.
