How do you enable consistency levels in Cosmos DB?

Short answer: Cosmos DB supports Strong, Bounded Staleness, Session, Consistent Prefix, Eventual. Set consistency when creating CosmosClient: var clientOptions = new CosmosClientOptions

Example code

{ ConsistencyLevel = ConsistencyLevel.Session }; var cosmosClient = new CosmosClient(endpointUri, primaryKey, clientOptions);

Real-world example (ShopNest)

ShopNest on Azure typically uses App Service + SQL Database + Blob Storage + Application Insights for monitoring.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
