Microsoft Certified: Azure Developer Associate Practice Exam 2025: Latest Questions

You are deploying an Azure Function that should run whenever a new blob is created in a specific container. You want to minimize custom code and configuration. Which trigger should you use?

You need to store application secrets (API keys and connection strings) centrally and retrieve them at runtime from an Azure App Service without storing secrets in code or configuration files. What should you use?

You are implementing a message-based integration between two services. Messages must be processed at least once and in the order they were sent within a session. Which Azure Service Bus feature should you use?

A web app needs to cache frequently accessed reference data to reduce load on a backend API and improve response times. You want a managed, distributed cache service. What should you use?

You are deploying a containerized ASP.NET Core API to Azure. You need simple container deployment with built-in HTTPS, scaling options, and minimal infrastructure management. Which compute option should you choose?

An Azure Function processes items from an Azure Storage queue. Occasionally, processing fails due to transient errors. You want failed messages to be retried automatically and then moved aside for later inspection after repeated failures. What should you implement?

You need to allow clients to upload blobs directly to a container without exposing the storage account key. Access must be time-limited and restricted to write-only. What should you use?

Your application uses Azure Cosmos DB and you need to optimize query performance and cost. You frequently query items by a single property (e.g., /customerId) and need efficient point reads and queries at scale. What should you do?

Your App Service must call an Azure SQL Database. Company policy forbids storing any credentials or connection strings containing passwords. The solution must use Azure AD and be manageable with least privilege. What should you implement?

A microservice calls an external REST API that enforces rate limits and occasionally returns transient 429 and 503 responses. You need a resilient approach that retries safely, uses exponential backoff, and avoids overwhelming the external service. What should you use?

You are developing an Azure Function that processes a message from an Azure Storage queue. The function occasionally fails due to a transient downstream API error. You need the message to be retried automatically without writing custom retry logic. What should you configure?

A web API uses Azure Key Vault to retrieve a certificate at startup. You must avoid storing any secrets in code or configuration files. What is the recommended authentication approach?

You need to store user-uploaded images in Azure Blob Storage so that clients can upload directly from a browser without exposing the storage account key. What should you provide to the client?

Your API uses Azure Cosmos DB (Core/SQL). You are receiving 429 (Request Rate Too Large) responses during traffic spikes. You want to minimize failed requests and latency without increasing the provisioned throughput. What should you do in the client code?

You are building an event-driven solution. Multiple downstream systems must react to the same event, and each system needs to receive its own copy of the event. You also need filtering and routing based on event type. Which Azure service best fits this requirement?

A Function App processes orders. You need to ensure that processing is not lost, supports duplicate detection, and guarantees ordered delivery per customer. Which messaging option should you choose?

You deploy an ASP.NET Core API to Azure App Service. The API must call a third-party service using a client certificate stored in Azure Key Vault. You need to avoid downloading the certificate to disk. What is the best approach?

Your team needs to troubleshoot intermittent failures in a distributed system consisting of an App Service API calling an Azure Function and then writing to Cosmos DB. You want end-to-end correlation across these components with minimal code changes. What should you implement?

You are designing a solution where multiple microservices publish domain events. A separate analytics service must consume all events, while other services consume only a subset. The solution must support at-least-once delivery and allow replay of events for a new consumer. Which service is the best fit?

You are implementing an Azure Durable Functions orchestrator that calls an activity to charge a customer. During a retry, the activity executes twice and causes a double charge. You must prevent duplicate side effects while keeping the orchestration reliable. What should you do?

You are building an Azure Function that processes messages from an Azure Service Bus queue. During a traffic spike, processing slows and the queue length grows. You want the function to automatically scale out based on queue backlog with minimal configuration. What should you use?

A web app must store user-uploaded images in Azure Blob Storage. The images must not be publicly accessible. The app should grant clients time-limited upload permission directly to Blob Storage without routing file bytes through the web server. What should you use?

An app uses Azure Key Vault to retrieve secrets. You want the app to authenticate to Key Vault without storing credentials in code or configuration, and you want Azure to handle credential rotation automatically. What should you use?

You are troubleshooting an intermittent failure across multiple microservices. You need to correlate a single end-user request as it flows through an API app, an Azure Function, and an Azure Service Bus-triggered worker. Which approach should you implement to enable end-to-end correlation in Application Insights?

Your API must call an external third-party REST service that enforces a strict rate limit. During bursts, calls return HTTP 429 responses. You need a resilient approach that reduces failures and avoids overwhelming the service while keeping latency reasonable. What should you implement?
