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
✓
Trunk-based development where developers merge small, frequent changes into a central main branch that drives automated pipelines.
GitFlow and trunk-based development describe common branching models; trunk-based development or short-lived feature branches with continuous integration are standard for modern DevOps.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Creating a separate permanent branch for every physical router in the network and never merging them.
Why it's wrong here
This creates unmaintainable branch drift and violates DRY (Don't Repeat Yourself) principles.
- ✗
Locking the master branch for 12 months while developing a single monolithic configuration update offline.
Why it's wrong here
This is waterfall methodology, contrary to CI/CD and DevOps.
- ✗
Using tag-based releases exclusively without utilizing any version control branches.
Why it's wrong here
Tags point to specific commits on branches; they do not replace branch management.
- ✓
Trunk-based development where developers merge small, frequent changes into a central main branch that drives automated pipelines.
Why this is correct
Correct. Trunk-based development facilitates continuous integration and automated testing.
