I'm not so sure about D, can someone explain?

B and C are where sharding shines, for sure.

Wait, isn't sharding supposed to help with large datasets?

Totally agree, D makes sense too!

A is definitely not a good reason for sharding.

I agree with Justine about A, but I also feel like D makes sense since sharding might complicate things for read-heavy scenarios.

I’m a bit confused about C. If the working set grows large, wouldn’t sharding help? I need to think this through more.

I remember practicing a question where sharding was not recommended for read-intensive collections, so I feel like D could be a correct answer too.

I think sharding isn't necessary when write operations are low, so maybe A? But I'm not entirely sure.

Okay, I've got a strategy here. I'll think about the pros and cons of sharding in each of these situations and try to determine which ones would not benefit from it.

Hmm, this is a tricky one. I'm not entirely sure about the details of when sharding is appropriate, but I'll try to reason through the scenarios and make my best guess.

The key seems to be identifying the characteristics of the collection that would make sharding not the right choice. I'll need to carefully consider the options and think about the trade-offs.

This question is asking about when sharding is not the correct option. I think I need to focus on understanding the different scenarios and how they relate to the decision to shard or not.

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.
