200-901 Infrastructure and Automation Practice Question
Which THREE are common best practices for implementing CI/CD in network automation?
⚠ Common exam trap
Cisco often tests the distinction between 'automation' and 'CI/CD best practices'—candidates may confuse manual testing (Option A) as a safety net, but the exam expects you to recognize that CI/CD relies on automated testing, not manual steps.

Correct answer & explanation
✓
Use version control for all automation scripts and playbooks
Version control (e.g., Git) is a fundamental CI/CD best practice: it tracks changes, enables rollbacks, and supports collaboration on automation scripts and playbooks. Without version control, you lose auditability and the ability to reliably reproduce network states, which violates the principle of infrastructure as code.
