You have a container named container1 in an Azure Cosmos DB Core (SQL) API account. You need to provide a user named User1 with the ability to insert items into container1 by using role-based access control (RBAC). The solution must use the principle of least privilege. Which roles should you assign to User1? 

You need to implement a solution to meet the product catalog requirements. What should you do to implement the conflict resolution policy.

You are having an Azure Cosmos DB Core (SQL) API account named account2 that has a container containing 100 GB of data.

In the container, you run the below-given query:

While running the query, you see the below metrics::

Here are some statements regarding the scenario:

Statement 1: The query uses an index.

Statement 2: The query performs a cross-partition query.

Statement 3: Recreating the container with the partition key set to /categoryId will improve the performance of the query.

Which of the above statements are true?

An Azure Cosmos DB Core (SQL) API account has a container that stores telemetry data from IoT devices. The container utilizes telemetryId as the partition key and has a throughput of 1000 RU/s (request units per second). Data is submitted by approx 5000 IoT devices by using the same telemetryId value every 5 minutes.

You have an app that does analytics on the data and reads telemetry data frequently for a single IoT device to have the trend analysis.

The below figure demonstrates the sample of a document in the container:

What would you do for reducing the number of RUs consumed by the analytics app?
