I think the birthday paradox is less relevant here, though.

The processing speed will brute force algorithms for sure!

Wait, can they really solve the discrete logarithm problem? Sounds too good to be true.

Quantum computers can factor large integers in polynomial time, right?

I definitely recall that quantum computers could brute force algorithms, but I think the real threat is their ability to factor large integers efficiently.

I feel like the birthday paradox was mentioned in class, but I don’t think it’s the main reason RSA is at risk from quantum computing.

I’m not entirely sure, but I think it has to do with solving the discrete logarithm problem? That sounds familiar from our practice questions.

I remember something about how quantum computers can factor large integers much faster than classical computers, which is a big deal for RSA.

Quantum computers can solve the birthday paradox, but I don't think that's the main reason they threaten RSA. I'm leaning towards option D, as I've heard that they can factor large integers much faster than classical computers.

The processing speed of quantum computers could potentially brute force RSA algorithms, but I think the real threat is their ability to solve the discrete logarithm problem, which is the foundation of RSA. Option B seems like the best answer.

Hmm, I'm a bit unsure about this one. I know quantum computing is a threat to RSA, but I'm not sure of the exact reason. I'll have to think this through carefully.

I'm pretty confident that the answer is D. Quantum computers can factor large integers in polynomial time, which would break the RSA encryption algorithm.

This is straightforward. The question is asking about the broader security program, not a specific control. The answer has to be information access management, which covers all those security best practices. B is the right choice.

This looks like a straightforward question about cloud access control. I'll eliminate the options that don't seem to fit and then select the best answer.

I'm a little confused by this question. Deduplication seems like it might be relevant, but I'm not sure how that would help the admin accomplish the task in the shortest amount of time. I'll have to review the concepts a bit more before answering.

Hmm, I'm not sure about that. Wouldn't a crash cart be a more reliable way to physically access the server and troubleshoot the issue?

I'm a little confused by the wording of the options. Do they all describe valid failover behaviors, or is there a clear "best" answer here? I'll need to re-read this carefully to make sure I understand the differences between the choices.
