200-901 Practice Question: A company uses a CI/CD pipeline to deploy network…
A company uses a CI/CD pipeline to deploy network configurations. The pipeline includes a stage that runs automated tests against a simulated network environment. Which testing strategy does this represent?
⚠ Common exam trap
Cisco often tests the distinction between integration testing and unit testing by describing a scenario that involves multiple components interacting, leading candidates to mistakenly choose unit testing because they focus on the word 'automated tests' rather than the environment (simulated network) that implies multi-device interaction.

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
✓
Integration testing
Running automated tests against a simulated network environment validates how multiple network components (e.g., routers, switches, firewalls) interact as a whole. This is integration testing, which focuses on detecting interface and communication failures between integrated units, not on individual components or end-to-end system behavior. In a CI/CD pipeline for network configurations, this stage ensures that the combined changes work together before deployment to production.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Regression testing
Why it's wrong here
Regression testing ensures that new changes do not adversely affect existing functionality, but the scenario is about testing in a simulated environment before deployment.
- ✗
Unit testing
Why it's wrong here
Unit testing tests individual functions or modules, not integrated configurations in a simulated environment.
- ✓
Integration testing
Why this is correct
Integration testing validates the interaction between components in a simulated or staging environment.
- ✗
Smoke testing
Why it's wrong here
Smoke testing is a preliminary test to check basic functionality, not a full test against a simulated environment.
