AZ-204 Quality Control & Assurance 5

Question 1

Which Azure DevOps work item type is most appropriate for tracking a defect found during QA testing?

Accepted Answer

Bug

Answer

The 'Bug' work item type is designed to capture defects, including reproduction steps, expected vs actual behavior, and priority, making it the standard QA tracking artifact.

Question 2

You are implementing chaos engineering for an Azure-hosted microservice. Which Azure service provides built-in fault injection experiments such as CPU pressure and network latency?

Accepted Answer

Azure Chaos Studio

Answer

Azure Chaos Studio lets you define experiments that inject faults—CPU stress, network delay, pod failures—into Azure resources to validate application resilience.

Question 3

In an Azure Pipelines YAML file, what is the correct way to publish test results so they appear in the pipeline summary?

Accepted Answer

Use the 'PublishTestResults' task with the appropriate resultFormat and searchFolder

Answer

The PublishTestResults task parses test result files (JUnit, NUnit, VSTest, etc.) and displays pass/fail counts, duration, and failure details in the pipeline UI.

Question 4

A team discovers that their Azure Function app silently swallows exceptions and returns HTTP 200 even on errors. Which Application Insights configuration helps detect this anti-pattern?

Accepted Answer

Create an alert on the 'exceptions/count' metric and review the Failures blade for logged exceptions

Answer

Tracking 'exceptions/count' in Application Insights and reviewing the Failures blade surfaces unhandled or explicitly logged exceptions even when the HTTP status code is 200.

Question 5

When using Azure Key Vault references in App Service application settings, which quality check should be part of the deployment pipeline to catch misconfigured secret URIs?

Accepted Answer

Run 'az webapp config appsettings list' and verify each @Microsoft.KeyVault() reference resolves successfully

Answer

Listing and resolving Key Vault references after deployment confirms that the Managed Identity has correct access and the secret URI is valid, catching misconfiguration before it reaches users.
