I'm pretty sure B and C are the correct answers here. Sharding is all about scaling out your database, so low write ops and read-heavy workloads don't really need that kind of heavy-duty solution.

Haha, I bet the exam writers were trying to trick us with these options. 'Very high write operations' and 'very large working set'? Sounds like a job for sharding if you ask me!

Wait, what? Sharding is not the correct option for low write operations? That's a head-scratcher. I guess I need to review my sharding fundamentals again.

I agree with Sena. Plus, D is a read-intensive collection, and sharding is a great option for that use case. Gotta love those MongoDB tricks!

But what about when the working set is expected to grow very large in size? Wouldn't sharding still be beneficial in that scenario?

Hmm, I think B and C are the correct answers here. Sharding is meant to handle high write operations and growing data sets, so those scenarios wouldn't be a good fit for sharding.
