AZ-204 Certification Practice Question #78

Question

You are developing a microservices-based application that uses Azure Container Apps. The application consists of several containerized services that handle tasks, such as processing orders, managing inventory, and generating reports. You deploy a new revision of the processing orders app.

Processing orders must be triggered by a web request and must always be available based on incoming web requests.

You need to validate that the replica is ready to handle incoming requests.

What should you implement?

Accepted Answer

A readiness probe is used in Azure Container Apps to determine if a replica is ready to handle incoming network traffic. Since the containerized service "processing orders" is triggered by web requests and must be available to process them, the health check should be done over HTTP (validating that the application layer is ready to respond to web traffic). Therefore, an HTTP readiness probe is the correct choice, while liveness probes (which trigger container restarts) and startup probes (which only check initial startup phase) do not fit the requirement.
