I’m a bit confused about the other options. I know content filtering is more for managing web content, not really for restricting inbound traffic like this question asks.

I feel like I've seen a similar question before, and it was about using an ACL to restrict traffic. So I think A is definitely the right choice.

I'm not entirely sure, but I remember something about port security being more about controlling devices on the network rather than filtering traffic from the internet.

I think the best option here is A, the ACL on the edge firewall. It seems like the most direct way to control inbound traffic.

Okay, I've got this. An ACL on the edge firewall is definitely the way to go. That will let me specifically permit HTTPS traffic while denying everything else. Shouldn't be too hard to set up.

Hmm, I'm a little unsure about this one. I know ACLs can be used for traffic filtering, but I'm not sure if that's the best approach here. Maybe I should also consider the other options like content filtering or URL filtering.

This looks like a pretty straightforward firewall configuration question. I'd start by thinking about how to set up an ACL on the edge firewall to only allow HTTPS traffic to the company website.

Port security on an access switch? Seriously? That's like using a spoon to shovel snow. Firewall ACL all the way, baby!
