CISCO DevNet Test

Before automation can be applied, a solid grasp of networking concepts is required. This area covers IP addressing, subnetting, routing, switching, VLANs, ACLs, NAT, DNS, and the OSI model—all through the lens of programmability. It ensures that candidates understand what they're automating and why, providing the context necessary to apply APIs and scripts to real-world networking tasks. This foundational skill prevents automation errors caused by misunderstanding how networks operate at the protocol level.

At the heart of DevNet lies API proficiency. This skill area teaches how to consume RESTful APIs, understand HTTP methods (GET, POST, PUT, DELETE), and interpret status codes. It also covers authentication mechanisms like OAuth2 and token-based access. APIs are the bridge between software and network infrastructure, allowing for automation, integration, and remote control of Cisco platforms. Mastery here ensures that candidates can confidently interact with APIs to manage network services programmatically and efficiently.

Security is critical in every programmable interface and automation workflow. This skill teaches candidates how to secure APIs and network access using authentication protocols (OAuth2, tokens), HTTPS, and role-based access. It also includes Cisco tools like ISE, Umbrella, and Firepower. Understanding how to automate securely—and how to avoid exposing sensitive credentials—is key to implementing trustworthy solutions. DevNet professionals must design automations that meet both functionality and compliance/security standards.

This skill focuses on integrating DevNet workflows into DevOps methodologies. It covers Git version control, Jenkins pipelines, testing frameworks (e.g., PyATS), and concepts like Continuous Integration and Continuous Deployment (CI/CD). Candidates gain insight into how network configurations and application deployments can be automated, tested, and delivered reliably. Emphasizing collaboration between development and operations, this skill helps break down silos and ensures that automation fits into broader organizational processes for faster innovation and reduced risk.

This skill area focuses on essential programming knowledge—primarily in Python—and basic software design principles like modular coding, version control (Git), and data serialization formats (JSON, YAML). Understanding these fundamentals is critical for developing automation scripts, interacting with APIs, and managing programmable infrastructure. Candidates also learn about control structures, data types, and best practices for maintainable code. This knowledge empowers network engineers to move beyond manual CLI tasks and into scripted, scalable network operations.

This skill covers hands-on familiarity with key Cisco platforms such as DNA Center, Meraki Dashboard, Webex APIs, and tools like PyATS, Genie, and DevNet Sandboxes. Understanding how to leverage Cisco's programmable interfaces and testing tools is essential for practical automation workflows. Candidates learn to navigate and utilize platform-specific APIs, making them capable of automating policy, security, telemetry, and more. This skill bridges theoretical knowledge with platform-specific execution—a core strength of DevNet-certified professionals.

Focused on DevOps-aligned workflows, this skill area explores how applications and infrastructure can be deployed and maintained automatically using tools like Docker, Ansible, and CI/CD pipelines. Candidates gain an understanding of concepts like containers, Infrastructure as Code (IaC), environment consistency, and automated testing. This is critical in hybrid environments where consistent provisioning and updates are required across distributed systems, allowing for faster releases and reduced configuration drift in networking and infrastructure.

This skill builds on the fundamentals by teaching model-driven configuration using YANG, RESTCONF, and NETCONF. It also explores telemetry, abstraction, and automation workflows. Candidates learn how to replace repetitive CLI-based management with scalable, consistent, and version-controlled automation scripts. This skill is central to DevNet's mission, enabling more agile network operations, reducing human error, and improving network visibility and compliance through programmable interactions.

Automated networks must be observable. This skill covers how to collect logs, analyze telemetry, and troubleshoot issues using APIs and tools like DNA Assurance, SNMP, syslog, and model-driven telemetry. Candidates learn how to detect anomalies, verify configurations, and implement alerting mechanisms. This ensures proactive problem resolution and closed-loop automation, essential for modern, self-healing infrastructure. Effective monitoring reduces downtime, boosts reliability, and supports continuous improvement cycles in DevOps environments.
