Which of the following protects against unauthorized access to confidential information via encryption and works at the network layer?

Show Suggested Answer Hide Answer
Suggested Answer: D

works at the network layer.

IPSec provides machine-level authentication as well as data encryption. It is used for VPN connections that use the L2TP protocol. It secures

both data and password.

Answer option B is incorrect. NAT also works at the network layer, but it does not provide encryption for data.

Really? I always thought NAT was more about IP address management.

Nope, firewalls mainly filter traffic, not encrypt it.

Wait, I thought firewalls handled encryption too?

IPSec is the right answer! It encrypts data at the network layer.

I feel like I've seen a question like this before, and IPSec was definitely mentioned in the context of securing data.

NAT is more about translating addresses, not really about encryption, so I don't think that's the answer.

I remember studying firewalls, but they don't specifically encrypt data, right? So I guess that's not it.

I think IPSec is the right answer since it deals with encryption at the network layer, but I'm not completely sure.

This seems pretty straightforward. I think the key is understanding the Microsoft 365 pricing model, which is likely based on the number of user licenses required.

This seems like a straightforward DHCP security question. I think the answer is to set a trusted interface for the DHCP server, which will help rate-limit the traffic and ensure legitimate requests aren't dropped.

Hmm, this looks like a configuration question. I'll need to carefully read through the options and think about the correct commands to assign the IP address to the interface.

I'm feeling pretty confident about this one. The shipping exception mentioned in option A is likely the culprit, so I'd start there and try to resolve any issues with the shipping process.
