AZ-400 Development Processes & Continuous Integration 2

Question 1

A team wants to enforce that no code is merged into the main branch without at least two reviewers approving the pull request. Where in Azure DevOps is this configured?

Accepted Answer

Branch policies in Azure Repos

Answer

Branch policies in Azure Repos allow you to require a minimum number of reviewers before a pull request can be completed.

Question 2

Which Azure Pipelines feature allows you to define reusable pipeline logic that can be called from multiple pipelines?

Accepted Answer

Templates

Answer

Templates in Azure Pipelines enable you to define reusable steps, jobs, or stages that can be referenced across multiple pipeline definitions.

Question 3

A developer commits code that breaks a shared library used by five downstream services. What CI practice would catch this regression earliest?

Accepted Answer

Multi-repo pipeline triggers that build dependents on library changes

Answer

Multi-repo pipeline triggers automatically build and test downstream services whenever the shared library is updated, catching regressions immediately.

Question 4

What is the primary purpose of a 'quality gate' in a CI pipeline?

Accepted Answer

To enforce minimum quality thresholds before allowing progression

Answer

Quality gates enforce defined thresholds (e.g., code coverage, test pass rate) and block pipeline progression if the code does not meet them.

Question 5

You need to run integration tests that require a SQL Server database in your Azure Pipeline. What is the recommended approach?

Accepted Answer

Use service containers in the pipeline YAML to spin up a SQL Server container per build

Answer

Service containers in Azure Pipelines spin up Docker-based dependencies like SQL Server for the duration of the job, providing isolation per build.
