Wait, are we sure about that? Central stores can be risky.

I think B is the right answer. Central identity stores can be a bottleneck.

Brokered Authentication? Sounds like a fancy term for a single point of failure. No thanks!

D. None of the above. This question is way too confusing.

I'm not sure about the increased dependency on a central token. Seems risky.

I’m leaning towards D, None of the above, but I can't recall the specifics that would support that choice.

I feel like we covered a question similar to this in practice, and it had to do with distributed tokens. Could it be A?

I'm not entirely sure, but I remember something about Direct Authentication and how it relates to identity stores. Maybe it's B?

I think the answer might be C, Brokered Authentication, because it sounds familiar from our discussions on token management.

I'm pretty sure the pattern they're talking about is Data Origin Authentication. That one uses distributed tokens instead of a central identity store. But I can't recall if that actually eliminates the need for anything - I'll have to think this through more carefully.

Okay, I remember learning about the Brokered Authentication pattern in class. I think that's the one they're referring to here. The key is understanding how it centralizes token management to avoid multiple identity stores, but can create a single point of failure. I'll go with option C.

Hmm, this seems like a tricky one. I'm going to need to think through the different authentication patterns we covered and how they impact things like tokens, identity stores, and single points of failure. Let me jot down a few key points before selecting an answer.

I think I know the pattern they're referring to, but I'm not totally sure about the details of how it works and what the tradeoffs are. I'll need to review my notes on authentication patterns before I can feel confident answering this.
