You have an Azure Cosmos DB for NoSQL container named Container1 that has a provisioned throughput of 1.000 request units per second (RU/s). Container1 is queried by using an app named App1.

Users of App1 report that several times a day, they receive the following error message: "HTTP error code 429." You need to improve the reliability of App1 without affecting the performance of the app. What are two ways to improve the reliability? Each correct answer presents a complete solution.
