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.

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.
