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?

In App1, modify the connection policy settings

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

In account1, provision a dedicated gateway and integrated cache

// explanation

BFD with a 300 ms interval × multiplier 3 = 900 ms detection, well under one second. Combined with a redundant Direct Connect at a different DX location, BGP withdrawal handles the cutover cleanly.
