Exam DP-420 topic 1 question 31 discussion

Answer 1: 5000 RU/s. You get this by dividing 30000 RU/s by 6 physical partitions. Answer 2: 60000 RU/s. The highest RU/s you can scale to without triggering Azure Cosmos DB to split partitions is equal to Current number of physical partitions * 10,000 RU/s. https://learn.microsoft.com/en-us/azure/cosmos-db/scaling-provisioned-throughput-best-practices#step-2-calculate-the-default-maximum-throughput

In an Azure Cosmos DB Core (SQL) API account, each partition supports throughput of up to 10,000 request units per second (RU/s). The container can scale to a maximum throughput of 30,000 RU/s without requiring a partition split. This is because the maximum RU/s per physical partition in Azure Cosmos DB is 10,000, and since the container is set to a manual throughput of 30,000 RU/s, it can be accommodated within three physical partitions, each handling 10,000 RU/s. Therefore, each partition supports up to 10,000 RU/s, and the container can scale up to 30,000 RU/s without a partition split.

https://learn.microsoft.com/en-us/azure/cosmos-db/scaling-provisioned-throughput-best-practices There's an example there. Answer 1: 5000 RU/s - throughput is evenly distributed between the 6 physical partitions Answer 2: That's a tricky one. Since it's manual, it will not go beyond 30.000 RU/s. But I think they mean how high you can possibly scale it to, and that would be 60.000, because each partition maximum can use 10.000

The correct answer should be 5000 RU/s and 60000 RU/s

How can you know there are 6 physical partitions?

5000 RU/s 10000 RU/s
