Suggested Answer: D

Integrity

https://en.wikipedia.org/wiki/Cryptographic_hash_function#Verifying_the_integrity_of_messages_and_files

An important application of secure hashes is verification of message integrity. Comparing message digests (hash digests over the message) calculated before, and after, transmission can determine whether any changes have been made to the message or file.

Nope, it's all about integrity, not confidentiality.

I feel like confidentiality isn't really covered by hashes, but I can't recall if availability is affected by them either.

I'm a bit confused; I thought hashes could also relate to authentication, but maybe that's just for digital signatures?

I remember practicing a question like this, and I think the answer was definitely integrity since hashes ensure data hasn't been altered.

I think hashes are mainly used for integrity, but I'm not completely sure if they also help with authentication.

Okay, I think I've got this. RTO is the acceptable amount of time to restore operations, and RPO is the acceptable amount of data that can be lost. I'll apply that knowledge to the options.

Hmm, I'm not entirely sure about this one. I'll need to think it through step-by-step to make sure I understand the full implications of deleting a user in this context.

Removing testers seems like a bad idea. We need all hands on deck, right? I recall a similar question where teamwork was emphasized.
