You are developing an Azure Function app that processes messages from an Azure Storage Queue. The function must scale automatically based on the number of messages in the queue. Which hosting plan should you use?

You are developing a containerized application that needs to run on Azure. The application consists of multiple containers that must be deployed together and share the same lifecycle. The solution must be serverless and automatically scale based on HTTP requests. Which Azure service should you use?

Your company has an Azure App Service web application that experiences performance issues during peak hours. You need to implement a solution that automatically adds more instances when CPU usage exceeds 70% for 5 minutes and removes instances when CPU drops below 30%. What should you configure?

You are developing an Azure Function using the .NET isolated worker model. The function needs to read configuration values from Azure App Configuration and cache them for 5 minutes to minimize calls. Which approach should you implement?

A serverless application uses Azure Functions with a Service Bus Queue trigger. During testing, you notice that messages are being processed multiple times even though they should only be processed once. What is the most likely cause?

You need to store 500 GB of unstructured data that will be accessed frequently for the first 30 days, then rarely accessed afterward. The solution must minimize costs. Which Azure Storage solution should you implement?

Your application needs to store JSON documents with complex queries including filtering, sorting, and aggregation. The solution must support automatic indexing and provide low-latency access. Which Azure storage service should you use?

You are implementing optimistic concurrency control for updating blobs in Azure Storage. The application reads a blob, modifies it, and writes it back. You need to ensure the blob hasn't been modified by another process between read and write operations. What should you implement?

Your web application needs to authenticate users and access Azure Storage on their behalf. The application is registered in Azure AD. Which authentication flow should you implement to securely access storage without storing credentials?

You need to secure sensitive configuration values like database connection strings for an Azure App Service application. The solution must support automatic rotation and centralized management. What should you use?

Your Azure Function needs to access an Azure SQL Database. You want to eliminate credential management and use the function's identity for authentication. What should you configure?

You are implementing API authentication for a REST API hosted in Azure App Service. The API will be consumed by multiple trusted partner applications. Each partner needs to have different rate limits and access permissions. What authentication mechanism should you use?

Your production Azure App Service application is experiencing slow response times. You need to identify which external dependencies are causing delays. What should you configure?

You need to implement distributed tracing across multiple microservices deployed in Azure. The solution must correlate requests across service boundaries and provide end-to-end transaction visibility. What should you implement?

An Azure Function is processing messages from a queue, but some messages are causing the function to fail repeatedly. You need to ensure failed messages are moved to a separate location after 5 failed attempts to prevent blocking other messages. What should you configure?

You are building a microservices application where Service A needs to call Service B synchronously. Both services are deployed as Azure Functions. You need to implement reliable communication that handles transient failures. What pattern should you implement?

Your application needs to react to blob upload events in Azure Storage and process them immediately. The solution must support at-least-once delivery and handle multiple event subscribers. Which Azure service should you use?

You are implementing a message-based architecture where messages must be processed exactly once and in the order they are sent. Multiple consumers will process different types of messages. Which Azure messaging service and configuration should you use?

Your application needs to implement a publish-subscribe pattern where multiple independent services subscribe to specific message types. Messages must be delivered to all active subscribers. Which Azure service should you use?

You are developing an API Management policy that needs to cache responses based on query string parameters for 1 hour, but only for GET requests with a specific API key. The cache should be separate for each unique combination of parameters. What policy configuration should you use?
