Each bucket having a unique hash? That sounds a bit off.

Hot buckets not using bloom filters makes sense.

Wait, false negatives too? I thought they only did false positives.

I’m a bit confused about the hashing algorithms for each bucket; I thought they could share the same one for their bloom filters.

I practiced a question similar to this, and I recall that bloom filters only use binary values, not trinary ones.

I think hot buckets might not use bloom filters because they change frequently, but I need to double-check that.

I remember bloom filters can definitely return false positives, but I’m not sure about false negatives.

The unique hashing algorithm for each bucket sounds like an important detail to remember. I'll make sure I understand how that works for bloom filters.

Wait, I'm confused about the part with the "hot buckets" - I'm not sure what that's referring to in the context of bloom filters. I'll have to re-read the question.

Okay, I remember learning about bloom filters in class. I think the key is understanding that they can have false positives, but not false negatives.

False positives, huh? Sounds like a good way to get some extra credit on the exam!

C seems like the right answer. Each bucket using a unique hashing algorithm makes sense for bloom filters.

I thought the bloom filter contained only binary values, 0 and 1. Interesting to learn about the trinary option D.

A) Hot buckets have no bloom filters as their contents are always changing.
CH

I believe option C is incorrect. Each bucket does not use a unique hashing algorithm for its bloom filter.

Option B is correct. Bloom filters can return false positives, but never false negatives.
GE

That's true. Bloom filters are designed to minimize false negatives.
BE

I agree with Elli. Bloom filters are probabilistic data structures that can have false positives or false negatives.
