20+ practice questions focused on Connect to and consume Azure services and third-party services — 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 Connect to and consume Azure services and third-party services PracticeYou are building an API that needs to send notifications to multiple subscribers. Each subscriber has a different callback URL, and you need to ensure each notification is sent exactly once and retried on failure. Which Azure service should you use?
Explanation: Azure Service Bus is the correct choice because it supports exactly-once delivery through duplicate detection and can fan out notifications to multiple subscribers using topics and subscriptions. It also provides built-in retry logic on failures. While Event Grid offers at-least-once delivery, only Service Bus can guarantee exactly-once when properly configured.
Your company uses Azure Logic Apps to automate workflows. A workflow must call an external REST API that requires an API key in the header. You need to securely store the API key and reference it in the Logic App without exposing it in the workflow definition. What should you do?
Explanation: Azure Key Vault provides a secure, centralized store for secrets like API keys, and the Logic App Key Vault connector retrieves the key at runtime without exposing it in the workflow definition. This approach ensures the secret is never stored in plain text within the Logic App's JSON definition or source control, aligning with Azure security best practices for managed identities and access policies.
You are building an Azure Logic App that needs to call an external HTTP API secured with OAuth 2.0 Client Credentials flow. The client ID and client secret are stored in Azure Key Vault. You need to obtain an access token and include it in the Authorization header of each request. Which combination of actions should you use within the Logic App?
Explanation: The HTTP action in Azure Logic Apps natively supports the OAuth 2.0 authentication type, which can directly handle the Client Credentials flow. By setting the client secret parameter to a secure reference (e.g., `@Microsoft.KeyVault(SecretUri=...)`) pointing to the secret stored in Azure Key Vault, you avoid exposing credentials in the workflow definition. The Logic Apps runtime automatically retrieves the secret from Key Vault, obtains an access token from the token endpoint, and includes it in the Authorization header of each request without requiring custom token management.
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?
Explanation: The EventProcessorHost (EPH) class is designed specifically for scenarios requiring distributed processing of Event Hub partitions across multiple instances. It manages partition leasing to ensure each partition is processed by only one instance at a time, handles checkpointing to track progress, and guarantees ordered processing within a partition. This makes it the correct choice for high-availability worker roles that must avoid duplicate processing and maintain event order.
A function consumes messages from Azure Service Bus. Which two settings help handle transient failures safely?
Explanation: Configuring max delivery count with a dead-letter queue is correct because it allows the function to handle transient failures safely by automatically moving messages that exceed the maximum number of delivery attempts to a dead-letter queue. This prevents infinite retries and ensures that problematic messages are isolated for manual inspection, while the function can continue processing other messages without blocking. The max delivery count setting in Azure Service Bus controls how many times a message is delivered before being dead-lettered, which is essential for managing transient failures without losing data.
