200-901 Practice Question: In a CI/CD pipeline for a network automation…
In a CI/CD pipeline for a network automation project, which stage is responsible for validating the syntax of YAML configuration files?
⚠ Common exam trap
Cisco often tests the distinction between static analysis (Lint) and dynamic verification (Test), so candidates may confuse syntax validation with functional testing and incorrectly select Test.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Lint
The Lint stage in a CI/CD pipeline is specifically designed to perform static analysis on code and configuration files, including YAML syntax validation. For network automation projects, tools like yamllint or ansible-lint check for indentation errors, missing colons, or invalid data types before the configuration is applied to network devices. This ensures that only syntactically correct YAML files proceed to later stages, preventing deployment failures.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy
Why it's wrong here
Deploy stage pushes code to production, syntax should be verified earlier.
- ✓
Lint
Why this is correct
Linting checks for syntax errors and coding standards in configuration files.
- ✗
Test
Why it's wrong here
Test stage runs functional or integration tests, not syntax checking.
- ✗
Build
Why it's wrong here
Build stage compiles source code, not for syntax validation of YAML.
