Wait, so we can't change the shard key at all? That seems odd.

I believe sharding is enabled at the database level, but I need to double-check if that’s the same for all databases.

I’m pretty sure a sharded environment can still sort documents, but I might be mixing it up with how queries work across shards.

I remember something about shard keys being unchangeable once set up, so I’m leaning towards option B.

I think sharding creates an index automatically, but I’m not entirely sure if that’s always the case.

I'm not entirely sure about D - is sharding really enabled at the database level? I'll need to review my notes on the sharding architecture.

A seems like the most straightforward answer. Creating a shard key automatically creates an index, that makes sense to me.

I'm a bit confused on the sorting functionality part. Does that mean we can't sort data in a sharded environment? I'll have to double-check that.

Okay, I've got this. I'm pretty sure the answer is B - we can't change the shard key once it's set up.

Hmm, I'm a bit unsure about this one. The question doesn't provide a lot of context, and I could see arguments for both B2B and B2C. I'll need to think it through carefully before answering.
