This question evaluates your knowledge of Azure Cosmos DB — a core concept tested in Microsoft Certified: Azure Fundamentals (AZ-900). Understanding Azure Cosmos DB is essential for designing scalable, secure, and cost-effective cloud architectures. Mastery of this topic will help you answer scenario-based questions confidently on exam day.
Your application generates millions of clickstream events per second. You need a service to ingest and buffer this data in real-time before processing it. Which service fits this need?
Which Azure Cosmos DB API should you use if your application is currently using a document database model and you want to migrate with minimal code changes?
Your application needs a globally distributed database that provides guaranteed single-digit millisecond latency at the 99th percentile. Which service is designed for this?
Which consistency level in Azure Cosmos DB provides the highest level of consistency but the highest latency and lowest availability?
Which consistency level is the default for a new Azure Cosmos DB account and offers a balance between performance and consistency that is ideal for most applications?
