Wait, is it really a capped collection for the oplog?

I practiced a similar question about replica sets, and I think A and C are the ones I would go with, but I'm still a bit confused about B.

I definitely remember that operations on the primary are logged in the oplog, so I think option C is definitely true.

I feel like option B might be true, but I can't recall if clients always read from the nearest member or if there's a setting for that.

I think option A is correct because I remember reading about how replica sets work in MongoDB, but I'm not entirely sure if it applies to all configurations.

Replication can be a tricky topic, but I've practiced a lot of questions like this. I'm going to read through the options carefully and eliminate any that don't sound right.

Hmm, I'm a little unsure about this. I know the market-based method looks at external factors, but I can't quite remember if it's primarily about the nature and level of work or the internal value. I'll have to think this through carefully.

Option B sounds right to me. Isn't that how MongoDB is designed to work, to read from the nearest member by default?

Hmm, I don't know about option B. Isn't that just a default setting that can be changed? Maybe it's not always true.

I think A and C are both true. The replica set members can replicate from each other, and the oplog is where the primary stores the operations.
