Just cleared the Azure Cosmos DB exam! Pass4Success practice questions were a huge help. There was a tricky question on integrating an Azure Cosmos DB solution with Azure Functions. I wasn't sure about the best way to trigger a function from a Cosmos DB change feed, but I still made it through.

My exam experience for the Microsoft Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB was successful, thanks to Pass4Success practice questions. I found the topic of implementing data access by using the Azure Cosmos DB SQL language to be particularly challenging. One question that I remember from the exam was about optimizing data access performance using the SQL language in Azure Cosmos DB. Despite some uncertainty, I was able to pass the exam.
