When using link encryption, packets have to be decrypted at each hop and encrypted again.
Information staying encrypted from one end of its journey to the other is a characteristic of end-to-end encryption, not link encryption.
Link Encryption vs. End-to-End Encryption
Link encryption encrypts the entire packet, including headers and trailers, and has to be decrypted at each hop.
End-to-end encryption does not encrypt the IP Protocol headers, and therefore does not need to be decrypted at each hop.

I thought link encryption only covered the payload, not the headers.

Headers and routing data are also encrypted, right?

Wait, does it really keep info encrypted all the way?

Link encryption does encrypt all data along the path.

I’m leaning towards option B being false, as I thought link encryption only protects data in transit, not necessarily against all types of attacks.

I feel like option D could be tricky since it mentions user information and headers, but I can't recall if those are always encrypted in link encryption.

I think link encryption encrypts everything along the path, but I'm not sure if it includes headers and routing data.

I remember practicing a question about link encryption, and I think option C might be the false one because it suggests end-to-end encryption.

Determining the metrics beforehand is key to avoid bias. Gotta keep the test objective and scientific!

I feel like I've seen a question like this before where it emphasized the importance of documentation. Maybe that's why issuing a written warning is the right move?

This is a good test of our understanding of virtual teams. I feel pretty confident I can identify the main advantages, so I'll carefully review the options and select the ones that apply.
