SSH is more for secure shell, not really a block cipher.

Wait, isn't DES considered weak nowadays?

I think RC4 is not a block cipher though.

SSH uses encryption, but I don’t recall if it specifically uses a symmetric block cipher. I guess I need to focus on the options given.

PGP is more about public key encryption, so I don't think that would work here either. I feel like I need to double-check the definitions.

I remember practicing with similar questions, and I think RC4 is a stream cipher, so it wouldn't fit the block cipher requirement.

I think DES might be the right choice since it's a symmetric key block cipher, but I'm not entirely sure if it's still considered secure enough for modern use.

Ugh, I'm not sure about this one. I know NTFS has some special file types, but I can't quite recall the details. I'll have to make an educated guess.

I'm leaning towards the evaluation of litigation since it often impacts financial statements, but I have some doubts.

I think marking with DSCP CS6 for management is a safe bet. It seems familiar from practice questions, especially when discussing critical traffic prioritization.
