Mastering CI/CD: Essential Interview Questions Quiz Quiz

1. Fundamental CI/CD Knowledge

   Which statement best describes the main goal of Continuous Integration (CI) in software development?

   1. A process for automatically testing and merging code changes frequently to detect issues early.
   2. A method for manually checking code for errors after deployment is complete.
   3. The practice of compiling code only when new features are requested.
   4. A way to store backups of source code in separate locations.
   5. An approach to design user interfaces before backend logic is written.

2. Understanding Pipelines

   If a CI/CD pipeline fails at the 'test' stage, what is the most appropriate immediate action for the development team?

   1. Review the test results and fix the failing tests before proceeding.
   2. Ignore the failure and continue to deploy to production.
   3. Rollback all previous successful builds.
   4. Skip testing for the current project and move on.
   5. Delete the pipeline configuration file completely.

3. Deployments in CI/CD

   In the context of CI/CD, what is meant by 'continuous deployment'?

   1. Automatically releasing every change that passes automated tests directly to production.
   2. Deploying applications once a year on a fixed schedule.
   3. Manually approving each deployment before it reaches the customers.
   4. Limiting deployments to development environments only.
   5. Updating documentation after each code release manually.

4. Benefits of Automation

   Why is automation important in a CI/CD pipeline, for example, when running security scans on new code?

   1. Automation ensures consistency and reduces human error during repetitive tasks.
   2. Automation increases manual review effort and delays project delivery.
   3. Automated pipelines cannot detect any security issues.
   4. Automation is only necessary for testing user interfaces.
   5. It is better to avoid automation as it complicates version control.

5. Version Control and CI/CD

   How does version control support the CI/CD process when multiple developers work on the same project?

   1. By allowing teams to collaborate, track changes, and resolve code conflicts efficiently.
   2. By preventing developers from creating feature branches.
   3. By forcing all changes to be deployed without review.
   4. By removing the ability to roll back faulty deployments.
   5. By discarding all previous versions of the project.
