20+ practice questions focused on Infrastructure and Automation — one of the most tested topics on the Cisco DevNet Associate 200-901 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Infrastructure and Automation PracticeAn engineer needs to automate the deployment of a new VLAN across multiple switches. Which tool is best suited for this task?
Explanation: Ansible is the correct tool because it is an agentless automation platform that uses SSH to push configuration changes, such as VLAN deployment, to network devices. It allows engineers to define the desired state of VLANs in YAML playbooks and apply them consistently across multiple switches without manual intervention.
A DevOps team wants to version control their network configurations. Which tool should they use?
Explanation: 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.
During an automation script run, a network device returns HTTP 429. What does this indicate?
Explanation: HTTP 429 (Too Many Requests) indicates the client has sent too many requests in a given amount of time, triggering rate limiting on the server. In network automation, devices like routers or switches enforce rate limits to prevent resource exhaustion, often based on RFC 6585. This is common when automation scripts exceed API call thresholds, requiring retry logic with exponential backoff.
A network automation engineer is writing a Python script to configure multiple devices. Which library is most appropriate for SSH-based interactions?
Explanation: Netmiko is a Python library built on top of Paramiko that simplifies SSH connections to network devices. It provides high-level methods for sending commands, handling prompts, and managing device interactions, making it the most appropriate choice for automating configuration tasks across multiple devices.
In a CI/CD pipeline for network changes, which practice best ensures that a configuration push does not disrupt production traffic?
Explanation: Canary deployment is the correct practice because it gradually introduces the configuration change to a small subset of devices or traffic before full rollout. This allows monitoring for adverse effects and automatic rollback if issues arise, minimizing the risk of production disruption. In a CI/CD pipeline for network changes, this approach aligns with incremental validation and risk mitigation.

Practice all Infrastructure and Automation questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Infrastructure and Automation. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Infrastructure and Automation questions on the 200-901 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Infrastructure and Automation is tested as part of the Cisco DevNet Associate 200-901 blueprint. Practicing with targeted Infrastructure and Automation questions ensures you can handle any format or difficulty that appears.
