Cisco 300-635 DCNAUTO Exam Objectives Breakdown
To pass, you must dominate these five core domains. Each requires a mix of theoretical knowledge and hands-on "code-level" understanding.
-
Network Automation Foundation (15%): This domain covers the "language" of automation. You must understand how to interact with REST APIs, parse data formats like JSON and YAML, and utilize Python libraries for network interactions.
-
Infrastructure as Code (25%): This is the heart of modern DevOps. You will be tested on your ability to use Ansible playbooks and Terraform providers to define your data center state. Understanding GitOps workflows and CI/CD pipelines is essential here.
-
Network Element Programmability (25%): Here, the focus shifts to specific platforms. You’ll need to demonstrate how to automate Cisco NX-OS using NETCONF/RESTCONF and how to manipulate the Cisco ACI object model via the APIC.
-
Operations (25%): Automation isn't just about Day 0 setup; it’s about Day 2 operations. This section covers Model-Driven Telemetry, troubleshooting automated scripts, and using Nexus Dashboard for proactive monitoring.
-
AI in Automation (10%): Reflecting the 2026 landscape, this domain tests your knowledge of how AI models assist in predictive analytics and automated incident response within the Cisco ecosystem.
Real-World Applications of DCNAUTO Skills
-
Provisioning: Deploying hundreds of VLANs across a leaf-spine fabric in seconds.
-
Compliance: Automatically auditing configurations against security baselines.
-
Scaling: Using AI-driven insights to trigger infrastructure expansion during peak loads.
