Sharding helps with scaling, but replication is what keeps it up and running!

Wait, are we sure about that? I thought write concern played a bigger role.

I feel like I’ve seen a similar question before, and I’m pretty sure replication is the right answer for ensuring fault tolerance in MongoDB.

I think MongoDB uses replication for high availability, but I'm not entirely sure if sharding plays a role too.

Ugh, I'm not feeling too great about this one. Sharding, indexing, and write concern all seem like they could be related to high availability in some way. I'll have to think this through carefully.

I'm pretty confident that the answer is Replication. MongoDB uses replica sets to provide redundancy and failover, which is key for high availability.
JO

Hmm, this seems like a tricky one. I'm not entirely sure, but I think it might be Replication. That's the first thing that comes to mind when they mention high availability and fault tolerance.

Okay, I've got this. The answer is Replication. MongoDB's replica sets ensure that data is replicated across multiple nodes, so if one node goes down, the others can take over. That's the core of their high availability strategy.

This seems like a pretty standard question about accessing updates. I'd recommend carefully reviewing the options and eliminating the ones that don't seem quite right. The answer is probably A or E.

Replication all the way! I heard MongoDB can even replicate data across different cloud providers. How cool is that?
ME

Replication, of course! Gotta love how MongoDB makes it so easy to set up and manage replica sets.
KA
Katina
