I agree with B, it's clear that learning is disabled.

C is misleading, remote MACs shouldn't be added either.

Wait, so new remote MACs can still be added? That seems odd!

I think A could be a possibility if the limit isn't reached.

I vaguely recall that disabling learning affects how MAC addresses are handled, but I can't remember if it stops local addresses while allowing remote ones. I need to think this through more.

I’m a bit confused about the difference between local and remote MAC addresses in this context. I feel like I might have seen something like option C in a different scenario.

I think option B sounds right because once learning is disabled, new source MACs shouldn't be entered at all. It feels similar to a practice question we did last week.

I remember something about the "disable-learning" command preventing new MAC addresses from being added, but I'm not sure if it applies to local or remote addresses.

The image shows a Facebook Page, so I'm guessing the main value is promoting your Facebook Page.

I'm unsure about option B; it sounds plausible, but I thought HINs were supposed to help reduce liability.

Hmm, I'm a bit unsure about this one. I know we need to disable Apple Pay for Spain, but I'm not sure which module would handle that specific configuration. I'll have to think it through step-by-step.

Okay, I think I've got a handle on this. I'll need to calculate the daily cash flow, the annual cost of short-term funds, and then compare the total annual costs for each proposal.
