Question 1

Which tool integrated with Azure Pipelines performs static application security testing (SAST) by scanning source code for vulnerabilities?

Accepted Answer

Microsoft Security DevOps (MSDO) / Defender for DevOps

Answer

Microsoft Security DevOps (part of Defender for DevOps) runs SAST tools like Bandit, ESLint, and Credential Scanner within Azure Pipelines to surface code-level security issues.

Question 2

What is the effect of enabling 'batch' mode on an Azure Pipelines CI trigger?

Accepted Answer

Waits for the current run to finish before starting a new run with all accumulated commits

Answer

With batch: true, if a run is in progress when new commits arrive, the pipeline queues one more run that includes all commits pushed since the current run started, rather than queuing one per commit.

Question 3

A .NET project uses a private NuGet feed hosted in Azure Artifacts. What task should be added to a CI pipeline to authenticate before restoring packages?

Accepted Answer

NuGetAuthenticate

Answer

The NuGetAuthenticate task configures NuGet credential providers so that subsequent restore commands can access private Azure Artifacts feeds without manual credential setup.

Question 4

In Azure Pipelines YAML, what is the purpose of the 'resources.pipelines' block?

Accepted Answer

Declares another pipeline whose artifacts or triggers this pipeline can consume

Answer

The resources.pipelines block lets a pipeline reference artifacts from—and optionally trigger on completions of—another Azure Pipeline.

Question 5

What does 'flaky test' mean, and how should a CI pipeline handle it?

Accepted Answer

A test that passes and fails non-deterministically; it should be quarantined and tracked separately

Answer

Flaky tests produce inconsistent results across identical runs due to timing, environment, or external dependencies, and should be quarantined to prevent false CI failures while being investigated.
