A healthcare system uses Azure Cosmos DB for NoSQL to store patient records. The system needs to react to updates in patient records by sending notifications to a third-party API. The team implements a change feed processor. They notice that some changes are processed multiple times, causing duplicate notifications. They want to ensure that each change is processed exactly once. Which approach should they take?

Use a lease container with a lower lease expiration time.

Use an idempotent notification endpoint that can handle duplicate messages.

Disable the change feed processor and use a trigger instead.

Use a second change feed processor to process the same changes.

Which action is most likely to reduce Request Unit (RU) consumption for a query in Azure Cosmos DB?

Adding a filter to the WHERE clause to reduce the result set

Switching to a different consistency level

Increasing the provisioned throughput of the container

A multinational company has an Azure Cosmos DB for NoSQL account configured with multiple write regions and Eventual consistency. A developer is writing a .NET application that needs to read data from the nearest region. The application uses the CosmosClient with the `ApplicationRegion` property set. The team wants to ensure that reads are served from the nearest region and that the application can fail over if a region becomes unavailable. Which additional configuration should the developer apply?

Set the `MaxRetryAttemptsOnRateLimitedRequests` property to a higher value.

Set the `ConsistencyLevel` property to Strong.

Set the `ApplicationPreferredRegions` property to a list of regions in priority order.

Set the `ConnectionMode` property to Direct.
