The Cisco 350-901 DEVCOR (Developing Applications Using Cisco Core Platforms and APIs) is a core exam under Cisco DevNet Professional.
It offers different development paths for various audiences:
- If you’re an IT beginner:
- Starting with development or network automation, DEVCOR provides a clear, structured direction to learn skills needed in real-world scenarios, such as APIs, automation, and deployment.
- If you’re a certified professional (e.g., CCNA or network engineer):
- Taking this exam can broaden your skill set, moving from pure network operations to a combination of “code + automation + deployment + security,” making you more competitive in the job market.
- If you’re an IT professional transitioning:
- For those previously in operations, networking, or system support looking to shift to DevOps, automation, or software development roles, DEVCOR is an ideal milestone.
Latest Changes (v1.0 → v2.0 AUTOCOR) and Their Impact on Preparation
Cisco officially announced that starting from February 3, 2026, the 350-901 DEVCOR exam will be updated to v2.0 and renamed 350-901 AUTOCOR (Designing, Deploying, and Managing Network Automation Systems).
Impacts include:
Certain topics in the current DEVCOR may be modified, removed, or newly added (for example, new content related to automation system management).
Study resources for DEVCOR (practice questions, sample tests, official guides) may become outdated by then, so it is important to verify whether they align with AUTOCOR.
If you plan to take the exam before 2026, focus on mastering the DEVCOR v1.0 topics , Exam structure and core topics; if your exam date is after 2026 or close to it, it is recommended to also review the new AUTOCOR blueprint.
Practical Experience and Study Stories
My 6-Week Study Plan:
- Week 1: Review Cisco exam blueprint, write summary notes, and set up the lab environment (Python, Postman, Docker, Ansible).
- Week 2: Focus on Software Development & APIs. Build a small project (API call → handle response → debug errors).
- Week 3: Practice Platform & Security (Docker deployment + simple CI/CD pipeline + basic API security).
- Week 4: Concentrate on Automation (write Ansible playbooks, try simple Terraform/CLI scripts).
- Week 5: Use Leads4Pass Exam Dumps (https://www.leads4pass.com/350-901.html) for intensive practice, create an error log, and review weak areas.
- Week 6: Take full mock exams (Leads4Pass VCE timed 120-minute simulation), focus on reviewing mistakes, keep the last 1–2 days relaxed.
