I’m a bit confused; I thought unbuffered queries were mainly about performance, but I’m not sure which options apply here.

I feel like unbuffered queries are supposed to use less memory, but I can't recall if they actually return all data faster.

I think unbuffered queries might return the first data faster, but I'm not entirely sure about the memory usage part.

I remember practicing a question like this, and I think unbuffered queries do help free up connections faster for other scripts.

This question seems a bit tricky, but I think I can work through it. Let me carefully read through the options and think about the flow of Instant Message and Presence delivery.

Okay, let's see here. Ambiguous requirements, poor design, and incorrect translation of design into code all seem like potential causes of defects. I wonder what the "signed off requirements" option could be referring to?

A and D, eh? Looks like the exam gods want us to choose between 'fast and furious' or 'slow and steady'. Gotta love those database dilemmas!

A and D, huh? Sounds like a classic case of trading speed for memory. I wonder if they have a query that's both fast and efficient - the holy grail of database queries!

Wait, if it frees the connection faster, doesn't that mean it also returns all the data faster? I'm so confused now. Maybe I'll just guess and hope for the best.

I always thought unbuffered queries were faster overall, not just for the first bit. But I guess B is out then. Hmm, I'll go with A and C.

I agree with Simona, option A makes sense because it doesn't wait to fetch all data before returning.

A and D seem like the correct answers. An unbuffered query doesn't wait to load all the data before returning it, which means you get the first bit faster and use less memory. Perfect for when you just need the top result.
