1. What type of configuration file does an AI tool typically analyze when refactoring a CI pipeline?

   1. Python source code files
   2. Shell script collections
   3. JSON-formatted database schemas
   4. YAML-based pipeline definitions

2. Which of the following is a task that AI performs well when assisting with CI pipeline refactoring?

   1. Identifying duplicate stages across multiple jobs in the pipeline
   2. Estimating the cloud infrastructure cost of running the pipeline
   3. Calculating the revenue impact of pipeline failures
   4. Determining which test combinations are required by legal compliance

3. What is a matrix build in CI/CD terminology?

   1. A build that uses a mathematical library for calculations
   2. A single job that runs the same steps across multiple configuration combinations
   3. A build that only runs on weekends
   4. A pipeline that compiles code into matrix format

4. Why might a team choose to keep removed matrix combinations as nightly runs instead of completely eliminating them?

   1. They may catch rare regressions that only occur under specific conditions
   2. Nightly runs are faster than regular CI jobs
   3. Teams want to intentionally slow down their feedback loop
   4. Nightly runs are required by all CI/CD platforms

5. What information is AI unable to know when proposing matrix combination reductions?

   1. Which combinations are mandated by external compliance requirements
   2. Which operating systems are currently supported
   3. How many developers have contributed to the repository
   4. What programming language version is being used

6. What type of historical data would be most useful for AI to propose effective matrix reductions?

   1. Historical pass rates for each matrix combination
   2. Git branch naming conventions
   3. Code review comment trends
   4. Developer commit frequency statistics

7. When AI drafts a refactored pipeline, what additional artifact does it typically provide for review?

   1. A requirements.txt file
   2. A diff showing before and after changes
   3. A compiled binary file
   4. A visual flowchart diagram

8. What does the term 'runtime' refer to in the context of CI pipeline optimization?

   1. The execution time of the entire pipeline from start to finish
   2. The time developers spend writing code
   3. The lifetime of the CI/CD platform
   4. The time a developer waits for code review

9. What risk exists when removing matrix combinations based on historical data alone?

   1. A rare regression might no longer be caught
   2. The CI platform will shut down
   3. The pipeline will run too quickly
   4. Developers will receive too much feedback

10. What does 'pipeline refactoring' mean in CI/CD contexts?

    1. Restructuring the CI pipeline configuration without changing its behavior
    2. Deploying the pipeline to production
    3. Manually running pipeline jobs
    4. Rewriting the application code being tested

11. Without what specific data type can AI NOT accurately predict changes in CI runner costs?

    1. Cloud provider billing data
    2. Developer productivity metrics
    3. Git commit timestamps
    4. Historical weather data

12. What is a 'redundant CI job' in a pipeline?

    1. A job that fails intentionally
    2. A job that duplicates work already done by another job
    3. A job that runs only on the main branch
    4. A job that deploys to production

13. What is the primary goal of consolidating CI jobs?

    1. To delete all test cases
    2. To reduce pipeline runtime while maintaining test coverage
    3. To increase the number of jobs in the pipeline
    4. To make the pipeline more complex

14. What is a 'nightly run' in CI/CD?

    1. A pipeline execution that runs automatically once per day, typically on the main branch
    2. A job that only runs on developer workstations
    3. A job that runs only when developers work late
    4. An urgent hotfix pipeline

15. Which external requirement might mandate specific matrix combinations that AI cannot infer?

    1. Industry compliance regulations
    2. The text editor being used
    3. The version control system's features
    4. The programming language's standard library
