Surprised that 'discard-unknown' isn't the first choice!

I think a MAC filter is a better option here.

Learning should definitely be disabled on those SAPs.

I think the 'discard-unknown' feature might be the right choice since it limits MAC learning, but I need to double-check my notes on that.

I’m a bit confused about whether an IP filter would actually help with FDB issues. I thought it was more about MAC addresses in this context.

This question feels similar to the practice ones we did about MAC learning and filters. I think applying a MAC filter could be a good option.

I remember we discussed how disabling learning on SAPs can help prevent FDB instability, but I'm not entirely sure if that's the best approach here.

Hmm, I'm not sure about Android - does Alibaba Cloud even have tools for that OS?

Okay, let me think this through. ActivcMatrix BusincssWorks is a business-focused platform, so the default HTTP server is likely a popular open-source option. I'll go with TOMCAT, option B.
