Question 2mediummultiple choice
Full question →You are developing a .NET Core application that stores session state data. The data is infrequently updated but must be read quickly for every user request. You need a serverless, globally distributed storage solution with low latency reads. Which Azure storage solution should you use?
Question 3mediummultiple choice
Full question →You are developing an application that writes logs to Azure Blob Storage. Each log entry is small (less than 1 KB) and you need to store millions of entries per day. You want to minimize storage costs and maximize write throughput. Which blob type should you use?
Question 4easymultiple choice
Full question →You are developing a solution that needs to run a background task every 10 minutes to clean up temporary files in Azure Blob Storage. You want to use Azure Functions with the Consumption Plan to minimize cost. Which trigger type should you use?
Question 5easymultiple choice
Full question →You are developing a solution that requires multiple Azure virtual machines to access the same set of files concurrently. The files are updated frequently and must be accessible with low latency. You need to choose a shared storage solution that integrates with Microsoft Entra ID (Microsoft Entra ID) for authentication. Which Azure storage solution should you use?
Question 6mediummultiple choice
Full question →You are developing an IoT solution that stores device metadata (device ID, location, firmware version, last seen timestamp) in Azure Table Storage. Each device has a unique DeviceId and a Timestamp. You need to design the PartitionKey and RowKey to optimize query performance for the following query: Retrieve all firmware versions for devices in a specific city that were last seen within the last 24 hours. The query must be efficient (partition scan minimized). Which key design is most appropriate?
Question 7easymultiple choice
Full question →You are developing a solution that stores large media files in Azure Blob Storage. Users access these files frequently for the first 30 days, then rarely afterwards. To optimize costs, you need to automatically move blobs to a cooler tier after 30 days of creation. Which Azure feature should you use?
Question 8mediummultiple choice
Full question →You develop an Azure Functions app that processes images triggered by blob uploads. You need to ensure the function can process images in parallel and handle high upload volumes without missing events. Which trigger and plan combination is recommended?
Question 9easymultiple choice
Full question →You are developing an application that stores user-uploaded profile pictures in Azure Blob Storage. Users frequently access these pictures for the first 7 days after upload, then rarely. To minimize costs, you need to automatically delete pictures that are older than 30 days. Which Azure Storage feature should you use to achieve this?
Question 10mediummultiple choice
Full question →You are developing a worker role that processes events from an Azure Event Hub. The worker runs on multiple virtual machines to ensure high availability. Each partition of the Event Hub should be processed by only one instance at a time, and events from the same partition must be processed in order. You need to manage partition leasing and checkpointing efficiently. Which Azure SDK class should you use?
Question 11mediummultiple choice
Full question →A developer is implementing least-privilege storage access. The application runs on Azure App Service and must avoid stored credentials. Which design should be used?
Question 12mediummultiple choice
Full question →A developer is implementing least-privilege storage access. The application runs on Azure App Service and must avoid stored credentials. Which design should be used? The design must avoid adding custom operational scripts.
Question 13mediummultiple choice
Full question →You are developing a C# application that stores sensitive documents in Azure Blob Storage. The application needs to generate a time-limited shared access signature (SAS) that allows a client to only read and list blobs in a specific container. The SAS must be valid for exactly 1 hour from the current time. Which code snippet correctly creates the SAS? (Assume the BlobServiceClient and BlobContainerClient are properly initialized.)
Question 14easymultiple choice
Full question →You are developing a solution that needs to perform a multi-step workflow. The workflow involves calling several third-party APIs, and some steps may require waiting for a human approval via email. The workflow may run for hours. You want to use Azure Functions to implement this orchestration. Which Azure Functions feature should you use?
Question 15easymultiple choice
Full question →You are developing an application that writes log entries to Azure Blob Storage. Each log entry is approximately 500 bytes, and you expect to generate millions of entries per day. The logs are rarely read, and when they are read, you need to retrieve ranges of logs sequentially. Which blob type should you use to minimize storage costs and maximize write throughput?
Question 16mediummultiple choice
Full question →You are developing an Azure Function that reads secrets from Azure Key Vault. The function must not use any static credentials in configuration files. You need to authenticate to Key Vault using the function's own identity. Which Azure service feature should you enable?
Question 17hardmultiple choice
Full question →You are developing an Azure Function that runs on a Consumption Plan. The function calls an external API that enforces a rate limit of 10 requests per second. When the function scales out to multiple instances, you must ensure the rate limit is not exceeded. Which pattern should you implement?
Question 18mediummultiple choice
Full question →You develop a serverless application using Azure Functions. The function must process images uploaded to a blob container. You need to ensure the function runs only when a new blob is created, and that it scales out automatically for high upload volumes. Which trigger and hosting plan combination should you use?
Question 19hardmultiple choice
Full question →You develop a C# application that stores sensitive documents in Azure Blob Storage. You need to generate a time-limited shared access signature (SAS) that allows a client to only read and list blobs in a specific container. The SAS must be valid for exactly 1 hour from the current time. Which code snippet correctly creates the SAS? (Assume BlobServiceClient and BlobContainerClient are properly initialized.)
Watch out for
Common Develop For Azure Storage exam traps
- ▸IaaS gives you infrastructure control; SaaS gives you only the application.
- ▸Hybrid cloud combines on-premises and public cloud — not two public clouds.
- ▸Cloud does not automatically mean cheaper or more secure.
- ▸Management responsibility shifts with each service model (IaaS → PaaS → SaaS).
