Cisco 300-635 Exam Questions

Free Cisco 300-635 Exam Questions and Detailed Explanations

The Cisco 300-635 DCNAUTO exam validates your ability to automate, orchestrate, and program Cisco data center networking environments using modern automation technologies and infrastructure-as-code practices. This certification exam is designed for professionals pursuing the Cisco Certified DevNet Professional, Cisco Certified Automation Specialist – Data Center Automation and Programmability, and Cisco Certified Network Professional Data Center certifications. Candidates preparing for this exam are expected to understand network programmability, infrastructure automation, orchestration workflows, and AI-driven operations across Cisco data center platforms.

Unlike traditional networking exams that focus mainly on manual configuration tasks, the 300-635 exam emphasizes automation, programmability, controller-based networking, and scalable operational workflows. Candidates must demonstrate the ability to work with APIs, YANG models, GitOps workflows, automation frameworks, and Cisco technologies such as Cisco ACI, Cisco Nexus Dashboard, Cisco NX-OS, and Cisco Nexus Hyperfabric. The exam measures both theoretical understanding and practical implementation skills that align with real-world enterprise automation environments.

Cisco 300-635 DCNAUTO Official Exam Topics

The following domains are based on the official Cisco exam blueprint for Automating Cisco Data Center Networking Solutions (300-635 DCNAUTO).

1.0 Network Automation Foundation

This section focuses on the foundational concepts required for automating Cisco data center environments. Candidates must understand OpenConfig, IETF, and native YANG models along with modern network programmability protocols such as NETCONF, gNMI, gRPC, and gNOI. The exam also tests your ability to work with Cisco ACI network-centric mode concepts including bridge domains, EPGs, contracts, and VRFs.

You are expected to understand the role of DPUs in data center switching environments and know how to construct gRPC payloads from YANG modules using tools such as YANG Suite and pyang. Cisco places strong emphasis on understanding how modern programmable interfaces interact with automation workflows in enterprise-scale data centers.

2.0 Infrastructure as Code (IaC)

Infrastructure as Code represents one of the most important areas of the updated DCNAUTO exam. Candidates must understand GitOps methodologies, infrastructure automation principles, and modern configuration management workflows. The exam validates your ability to build reusable and scalable network automation templates using Jinja2 features such as loops, filters, conditionals, and output modifiers.

This domain also covers automation using Python, Ansible, Terraform, and CI/CD methodologies within data center environments. You must understand how infrastructure provisioning, validation, and deployment pipelines are integrated into automated operational models. Cisco increasingly focuses on repeatable and version-controlled automation practices that reduce operational risk in enterprise infrastructures.

3.0 Network Element Programmability

This domain evaluates your ability to automate and manage Cisco data center platforms using APIs and programmable interfaces. Candidates are expected to interact with Cisco NX-OS, Cisco ACI, and Nexus Dashboard APIs while understanding authentication methods, API response handling, and operational automation workflows.

You should know how to retrieve operational data, automate device configurations, and validate infrastructure states programmatically. Cisco also tests your understanding of structured data formats such as JSON and XML and their role in automation systems. This section heavily focuses on real-world automation use cases rather than simple theoretical memorization.

4.0 Operations and AI in Automation

The Operations and AI section reflects Cisco’s growing emphasis on intelligent automation and AI-assisted infrastructure operations. Candidates must understand automation-driven operational workflows, monitoring systems, event-driven automation, and AI-powered operational visibility.

This domain covers telemetry collection, operational analytics, infrastructure validation, and the use of intelligent automation systems to improve efficiency and reliability within modern data center environments. Cisco expects professionals to understand how AI and automation technologies integrate into modern enterprise networking operations to support predictive analysis and self-healing infrastructure models.

Understanding the 300-635 Exam Structure

The Cisco 300-635 exam includes a combination of theoretical and scenario-driven questions designed to evaluate practical implementation knowledge. Most questions focus on real operational environments where candidates must determine the best automation approach based on technical requirements and infrastructure constraints.

Multiple-Choice Questions

These questions evaluate your understanding of APIs, programmability protocols, automation frameworks, infrastructure-as-code concepts, and Cisco automation technologies. Candidates must understand terminology, operational behavior, and workflow integration rather than relying on memorization alone.

Scenario-Based Questions

Scenario-based items present realistic enterprise data center situations involving automation challenges, controller-based architectures, or operational troubleshooting tasks. These questions test analytical thinking and your ability to apply automation concepts to production environments.

Matching and Drag-and-Drop Questions

These questions measure your ability to associate technologies with their operational functions. You may be required to match YANG models with protocols, APIs with automation tasks, or automation tools with deployment workflows.

Effective Preparation Strategy for Cisco 300-635

Preparing for the 300-635 exam requires both conceptual understanding and practical automation experience. Candidates who combine theory study with hands-on practice generally perform significantly better on scenario-driven questions.

Start by building a strong understanding of automation foundations including REST APIs, JSON, YANG models, Git workflows, and programmable networking protocols. Once you are comfortable with these fundamentals, move toward Cisco-specific technologies such as Cisco ACI, Cisco NX-OS automation, and Nexus Dashboard integrations.

Hands-on practice is extremely important for this certification. Working with Python scripts, API calls, automation templates, and orchestration tools helps reinforce concepts that frequently appear in practical exam scenarios. Candidates should also practice interpreting API responses and troubleshooting automation workflows within simulated environments.

A structured weekly study plan helps ensure balanced preparation across all official domains. Spend additional time on Infrastructure as Code and Network Automation Foundation topics because these areas contain substantial conceptual depth and operational relevance.
