Certification Overview
This exam tests your ability to develop applications using REST APIs and RESTCONF to interact with Cisco platforms (Meraki, DNA Center, ACI), automate network operations with Ansible and Python, implement infrastructure-as-code patterns, and secure API-driven deployments in containerized environments.
What This Certification Proves
The DEVCOR certification validates your ability to develop applications that interact with Cisco platforms and APIs, combining network automation with software development practices. This credential proves you can design, build, and deploy applications using REST APIs, infrastructure-as-code tools, and Cisco's ecosystem (Meraki, DNA Center, etc.), making you qualified for modern NetDevOps and cloud-native roles.
Who Should Take This Exam
Software developers transitioning to network automation, network engineers moving into DevOps/automation roles, IT professionals with 1-3 years of experience, and anyone building applications that consume Cisco APIs or orchestrate network infrastructure.

350-901-Specific Tips
- Prioritize Python hands-on labs—questions focus on practical API integration, not just theory. Build scripts to interact with Meraki and RESTCONF APIs.
- Understand HTTP fundamentals deeply: status codes, methods (GET/POST/PUT/DELETE), headers, and authentication mechanisms are tested across multiple domain areas.
- Practice Docker and container basics—containerization is a key topic, and understanding app deployment in containers is essential.
- Set up a lab environment with Cisco Meraki sandbox or DevNet Always-On labs to test REST API calls and RESTCONF operations in real scenarios.
- Study both Ansible playbooks and Python SDK approaches for network automation—the exam covers multiple tools for infrastructure-as-code.
- Review API security patterns: OAuth, API keys, certificate-based auth, and secure credential handling in automation scripts.
- Work through the 67 practice questions strategically—with 2.4 average difficulty, focus on understanding WHY answers are correct, not just memorizing.
