Wait, can it really stop legitimate MAC addresses too?

I don't think it affects Network Access Control systems directly, so I would lean towards option B as the correct answer.

I feel like I saw a practice question that mentioned legitimate MAC addresses being blocked, but I can't recall if that's what port security does.

I think option B sounds right because we talked about how port security can help mitigate DoS attacks by blocking those spoofed addresses.

I remember studying that port security is mainly about preventing unauthorized devices from connecting, but I'm not sure if it specifically stops spoofed MAC addresses.

I'm a little confused by the wording of the question. Does "enabling port security" mean that it's already enabled, or that you're enabling it for the first time? I want to make sure I understand the context before I answer.

Okay, I think I've got this. Port security is a security feature that restricts access to a port based on the MAC address of the connected device. So it would prevent spoofed MAC addresses from being used to cause a denial of service, which is option B.

Hmm, I'm a bit unsure about this one. I know port security has something to do with MAC addresses, but I'm not sure if it's specifically for preventing spoofed addresses or just any kind of MAC address-related issues. I'll have to think about this one a bit more.

This one seems pretty straightforward. Port security is designed to prevent MAC address spoofing, so I'm going to go with option B.

This is a good one. Port security is all about controlling access to ports and preventing unauthorized access, so option B seems like the correct answer here. I'm pretty confident in that.

The scope document seems like the obvious choice here. It defines the boundaries and parameters for the product development, so that should provide the best guidance.
