20+ practice questions focused on Develop Azure compute solutions — one of the most tested topics on the Microsoft Azure Developer Associate AZ-204 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Develop Azure compute solutions PracticeYou are implementing an Azure Durable Functions application that processes orders. The function must call three external APIs (payment gateway, inventory system, and shipping calculator) in parallel, then aggregate the results once all three have completed. Which Durable Functions pattern should you use?
Explanation: The Fan-out/Fan-in pattern is designed exactly for this scenario: it triggers multiple function tasks in parallel (fan-out) and then aggregates their results once all complete (fan-in). In Durable Functions, this is implemented using `CallActivityAsync` in a loop with `Task.WhenAll` to wait for all parallel activities to finish, allowing the orchestrator to collect and process the combined results.
A company uses Azure Functions with a consumption plan. The function processes messages from a queue. During peak hours, the function takes longer to execute, and some messages are processed twice. What is the most likely cause?
Explanation: In Azure Functions with a consumption plan, the queue message visibility timeout determines how long a message is invisible to other consumers after being dequeued. If the function's processing time exceeds this visibility timeout, the message becomes visible again and can be picked up by another function instance, leading to duplicate processing. This is the most likely cause of messages being processed twice during peak hours when execution times increase.
You are deploying a Node.js application to Azure Web Apps for Containers. The application needs to read configuration settings from Azure App Configuration. What is the recommended method to securely connect the app to the configuration store?
Explanation: Option C is correct because using a managed identity allows the Node.js application running in Azure Web Apps for Containers to authenticate to Azure App Configuration without storing any secrets. Managed identities provide an automatically managed service principal in Azure AD, enabling secure, code-free access to the configuration store via Azure AD authentication, which is the recommended approach for production workloads.
You are implementing an order processing system using Azure Durable Functions. The function must send notifications to multiple channels (email, SMS, push) in parallel and wait for all to complete before sending a confirmation. Which Durable Functions feature should you utilize?
Explanation: The fan-out/fan-in pattern in Durable Functions allows you to invoke multiple activity functions in parallel (fan-out) and then wait for all of them to complete (fan-in) using `Task.WhenAll`. This is exactly what is needed to send notifications to email, SMS, and push simultaneously and then proceed only after all have finished, making option A correct.
You are deploying a sensitive configuration to Azure Container Instances. The configuration must be encrypted at rest and not visible in the container logs. What should you use?
Explanation: Azure Key Vault with managed identity and secret volumes is the correct choice because it allows you to mount secrets as files into the container without exposing them in environment variables or logs. The secrets are encrypted at rest in Key Vault and are only accessible via a managed identity assigned to the container group, ensuring the configuration remains secure and invisible in container logs.
