AZ-204: Developing Solutions for Microsoft Azure

By Microsoft · Browse Mode
About the Exam

An exam for Azure developers who participate in all phases of application development and have about two years of programming experience. It covers Azure compute, storage, security, monitoring, troubleshooting, and connecting to Azure and third-party services, with emphasis on SDKs, APIs, authentication, functions, web apps, and containers. Passing demonstrates that you can build and maintain end-to-end solutions on Microsoft Azure and is the exam for the Microsoft Certified: Azure Developer Associate credential. Microsoft says the exam is scheduled to retire on July 31, 2026.

QuestionQ1

Connect to and consume Azure services and third-party services

You need to deploy a new version of the LabelMaker application to ACR.

Which three actions should you perform, in sequence?

Drag & Drop
Explanation

A Dockerfile builds the application image. Before an image can be pushed to Azure Container Registry, it must be tagged with the registry login server and repository path; after authentication, Docker can push that tagged image. A separate build-number alias is optional and is not necessary for this sequence.

QuestionQ2

Develop Azure compute solutions

You deploy an Azure Container Apps app and turn off ingress on the container app.

Users report that they can’t access the container app. You investigate and find that the app has scaled to 0 instances.

You need to resolve the issue with the container app.

Solution: Turn on ingress, create a custom scale rule, and apply that rule to the container app.

Does this solution meet the goal?

Explanation

Azure Container Apps requires either ingress, a minimum replica count, or a custom scale rule to avoid an app with disabled ingress becoming unable to start after scaling to zero. Enabling ingress permits users to reach the app, while the custom scale rule supplies a scaling trigger that can activate replicas. Scaling in Azure Container Apps | Microsoft Learn

QuestionQ3

Develop Azure compute solutions

You deploy an Azure Container Apps app and turn off ingress on the container app.

Users report that they can’t access the container app. You investigate and find that the app has scaled to 0 instances.

You need to resolve the issue with the container app.

Solution: Turn on ingress and set the container app's minimum replica count to 1.

Does this solution meet the goal?

Explanation

Azure Container Apps requires ingress to expose an app to incoming traffic. A minimum replica setting of 1 keeps at least one revision replica running instead of allowing the app to scale to zero, restoring availability for users.

QuestionQ4

Develop Azure compute solutions

You deploy an Azure Container Apps app and turn off ingress on the container app.

Users report that they can’t access the container app. You investigate and find that the app has scaled to 0 instances.

You need to resolve the issue with the container app.

Solution: Turn on ingress, create an HTTP scale rule, and apply that rule to the container app.

Does this solution meet the goal?

Explanation

Azure Container Apps with ingress disabled can scale to zero and have no HTTP-based way to start again. Enabling ingress makes the app reachable for HTTP traffic, while an HTTP scale rule uses incoming request concurrency to scale the app out from zero. Scaling in Azure Container Apps

QuestionQ5

Develop Azure compute solutions

You deploy an Azure Container Apps app and turn off ingress on the container app.

Users report that they can’t access the container app. You investigate and find that the app has scaled to 0 instances.

You need to resolve the issue with the container app.

Solution: Enable ingress, create a TCP scale rule, and apply that rule to the container app.

Does this solution meet the goal?

Explanation

Enabling ingress makes the container app reachable, and a TCP scaling rule can trigger replicas from incoming TCP connections even when the revision has scaled to zero. Azure Container Apps documents TCP scaling with minReplicas set to 0 and ingress configured for TCP traffic.
