Quick Answer
The answer is Git, as it is a distributed version control system specifically designed to track changes in source code and configuration files, making it the correct tool for version controlling network configurations. Unlike configuration management tools like Ansible or Puppet, which focus on automation and state enforcement, Git provides commit history, branching, and rollback capabilities that are essential for managing iterative changes to network device configs. On the Cisco DevNet Associate 200-901 exam, this question tests your understanding of Git’s role in a DevOps workflow, often appearing in scenarios where the team needs to audit or revert configuration changes. A common trap is confusing Git with configuration management tools—remember that Git is for version control, not for pushing configs to devices. Memory tip: Git tracks history, not hardware.
This 200-901 practice question tests your understanding of infrastructure and automation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A DevOps team wants to version control their network configurations. Which tool should they use?
Puppet
Why wrong: Puppet is a configuration management tool, not primarily for version control.
Jenkins
Why wrong: Jenkins is a CI/CD tool.
Git
Git is the standard for version control.
Docker
Why wrong: Docker is for containerization.

Correct answer & explanation
Git
Git is a distributed version control system that tracks changes in source code and configuration files, making it the ideal tool for version controlling network configurations. Unlike configuration management tools, Git provides commit history, branching, and rollback capabilities specifically designed for version control.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Puppet
Why it's wrong here
Puppet is a configuration management tool, not primarily for version control.
Jenkins
Why it's wrong here
Jenkins is a CI/CD tool.
Git
Why this is correct
Git is the standard for version control.

Docker
Why it's wrong here
Docker is for containerization.
Common exam traps
Cisco often tests the distinction between version control tools (Git) and configuration management tools (Puppet, Ansible) or CI/CD tools (Jenkins), leading candidates to confuse the purpose of each tool in the DevOps pipeline.
Detailed technical explanation
Git uses a directed acyclic graph (DAG) of commits, each identified by a SHA-1 hash, to ensure integrity of version history. When versioning network configurations, teams can leverage Git's branching strategy to manage changes across different environments (e.g., staging vs. production) and use hooks to trigger validation or deployment pipelines. Real-world scenarios include storing router configurations as text files in a Git repository and using git diff to review changes before applying them.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
