JNCIA-DevOps Junos Automation Stack And DevOps Concepts Practice Question
A DevOps engineer is designing a CI/CD pipeline for validating Junos configuration changes prior to deployment. Which THREE actions are typically performed during the automated CI pipeline 'test' or 'validate' stage? (Choose THREE)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Performing dry-run validation checks against staging or virtual Junos instances (vSRX)
CI validation stages typically run linting checks, static syntax validation against Junos schemas, and unit testing of templates or automation code before deployment staging.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Performing dry-run validation checks against staging or virtual Junos instances (vSRX)
Why this is correct
Testing against virtual instances (vSRX) validates behavior against real Junos parsing logic.
- ✗
Immediately rebooting the production core routing engine to apply all updates
Why it's wrong here
Rebooting production devices arbitrarily during CI test phases causes outages and is not a CI validation task.
- ✓
Running automated linters and style checks on Python automation scripts and Jinja2 templates
Why this is correct
Linters (like flake8 or yamllint) verify code quality and style compliance in scripts and templates.
- ✓
Executing static syntax and semantic validation of candidate configurations against device schemas
Why this is correct
Syntax and schema validation ensures configurations are free of typos and invalid Junos hierarchy.
- ✗
Manually logging into physical CLI consoles to troubleshoot cabling
Why it's wrong here
Manual physical troubleshooting is a reactive operational task, not part of an automated CI pipeline.
