Cisco 350-901 is the 120-minute, $400 core exam for what is now the CCNP Automation credential. The exam was renamed from DEVCOR to AUTOCOR effective February 3, 2026 (the CCNP DevNet Professional track was rebranded to CCNP Automation on the same date), but the underlying blueprint of five domains weighted at 20% each is unchanged. It tests Python, REST and OAuth2 APIs, Cisco platforms (Webex, Meraki, Intersight, UCS, Catalyst Center, Firepower, AppDynamics), CI/CD and security with Docker/Kubernetes, and infrastructure automation with RESTCONF, gNMI, Ansible, Terraform, and Cisco IOx. Cisco does not publish a fixed passing score or pass rate.

Frequently Asked Questions
What is the Cisco 350-901 DEVCOR/AUTOCOR exam?
Cisco 350-901 is the 120-minute core exam for the CCNP Automation credential (formerly CCNP DevNet Professional). It validates skills in software development and design, REST and OAuth2 APIs, Cisco platforms, application deployment and security, and infrastructure automation. The exam costs $400 USD and is delivered by Pearson VUE.
Why is the 350-901 exam now called AUTOCOR instead of DEVCOR?
Effective February 3, 2026, Cisco rebranded the CCNP DevNet Professional track to CCNP Automation, and the 350-901 core exam was renamed from DEVCOR (Developing Applications using Cisco Core Platforms and APIs) to AUTOCOR with the same five-domain blueprint and the same 20% per-domain weights. Existing study materials labeled DEVCOR remain valid for 350-901 preparation; only the track name and exam acronym changed.
How many questions are on Cisco 350-901, and what is the passing score?
Cisco 350-901 typically delivers 90 to 110 multiple-choice, multiple-response, drag-and-drop, and simulation items in 120 minutes. Cisco does not publish a fixed passing score for the exam, and Cisco does not publish pass rates.
How much does the Cisco 350-901 exam cost?
The Cisco 350-901 exam costs $400 USD per attempt, plus applicable taxes. It is administered by Pearson VUE either at a testing center or via online proctored delivery.
What topics does the 350-901 cover?
350-901 covers five evenly weighted (20% each) domains: Software Development and Design (Python, microservices, twelve-factor, Git, semver), Using APIs (REST, rate limits, OAuth2 with PKCE), Cisco Platforms (Webex, Meraki, Intersight, UCS, Catalyst Center, Firepower, AppDynamics), Application Deployment and Security (Docker, Kubernetes, CI/CD, OWASP), and Infrastructure and Automation (RESTCONF, gNMI/gNOI, Ansible, Terraform, IOx).
What is the prerequisite to take 350-901?
Cisco does not impose a formal prerequisite for 350-901, but recommends 3 to 5 years of software-development experience and working familiarity with Cisco platforms and APIs. Most candidates also pair the core exam with a concentration exam such as 300-435 ENAUTO to complete the CCNP Automation credential.
How long is the Cisco 350-901 certification valid?
Cisco professional-level certifications are valid for 3 years. Recertify by earning a higher-level certification, passing the current core exam, completing Cisco Continuing Education credits, or a combination of these activities before the expiration date.
