You have an application named App1 that uses the Azure Cosmos DB SDK and performs a point read on the same set of items in container1 every minute.

You need to minimize the consumption of the request units (RUs) associated to the reads by App1. What should you do?

Select an option, then click Submit answer.

  • ○

    In account1, change the default consistency level to bounded staleness.
  • ○

    In App1, change the consistency level of read requests to consistent prefix.
  • ○

    In account1, provision a dedicated gateway and integrated cache
  • ○

    In App1, modify the connection policy settings.
