Cisco Certified Network Associate (CCNA) and Cisco Certified Network Professional (CCNP): Mastering Network Automation and Programmability Study Guide
As networks grow in complexity, the need for efficient management and scalability has driven the adoption of network automation and programmability. Cisco has embraced this shift, incorporating automation concepts into its Cisco Certified Network Associate (CCNA) and Cisco Certified Network Professional (CCNP) certifications. These credentials now emphasize not only traditional networking skills but also the tools and methodologies required to automate and program modern networks.
In this study guide, we’ll explore how network automation and programmability are integrated into the CCNA and CCNP certifications, the skills you’ll need to master these concepts, and their importance in shaping the future of networking.
The Role of Automation and Programmability in Modern Networking
Network automation and programmability are about reducing manual configurations and enabling dynamic, scalable, and efficient network management. This involves using tools, scripts, and protocols to automate repetitive tasks like device provisioning, configuration updates, and monitoring.
Key Benefits of Network Automation
- Increased Efficiency: Reduces time spent on manual tasks.
- Consistency: Minimizes human errors in configurations.
- Scalability: Facilitates managing large-scale networks.
- Agility: Enables faster deployment of services and changes.
CCNA and Network Automation
The CCNA certification introduces foundational concepts of network automation and programmability, ensuring that candidates are equipped with the basics of managing modern networks.
Key Topics in CCNA Related to Automation
Automation Basics:

Command-Line Automation:
- Introduction to Python for scripting basic automation tasks.
- Using CLI-based tools to interact with network devices programmatically.
The goal at the CCNA level is to provide a solid understanding of how automation complements traditional networking, preparing candidates for more advanced concepts in CCNP.
CCNP and Advanced Network Automation
The CCNP certification delves deeper into the principles of network automation and programmability, offering specialized knowledge tailored to advanced network management.
Core Concepts of Automation in CCNP
Model-Driven Programmability:
- Using YANG models to structure device configurations.
- Leveraging NETCONF and RESTCONF protocols for device management.
Advanced Python Scripting:
- Writing Python scripts to automate complex network tasks.
- Interacting with APIs and parsing JSON/XML outputs.
Cisco SD-WAN Automation:
- Automating WAN configurations with Cisco’s SD-WAN solutions.
- Monitoring and managing WAN connections programmatically.
Network Orchestration Tools:
- Familiarity with tools like Ansible and Puppet for automating configuration management.
- Implementing playbooks to standardize network deployments.
Telemetry and Monitoring:
- Collecting real-time network data using streaming telemetry.
- Analyzing and visualizing data with tools like Grafana and Kibana.
Building Automation and Programmability Skills
Mastering automation and programmability requires a combination of theoretical knowledge and practical experience. Cisco integrates these concepts into its CCNA and CCNP certifications to align with industry demands, emphasizing hands-on proficiency.
Foundational Skills to Develop
Scripting Knowledge:
- Python is the most widely used language for network automation. Understanding loops, conditionals, and API interactions is crucial.
API Mastery:
- RESTful APIs allow seamless integration with network devices and services. Learning how to make API calls and handle responses is essential.
Understanding Data Formats:
- JSON and XML are standard data formats used in network automation. Proficiency in parsing and manipulating these formats is vital.
Automation Frameworks:
- Tools like Ansible and Terraform simplify large-scale network deployments. Familiarity with these frameworks boosts efficiency.
Version Control:
- Git is essential for managing configuration changes and collaborating with teams. Understanding repositories and versioning workflows is key.
The Importance of Network Automation and Programmability
With the rise of software-defined networking (SDN) and intent-based networking (IBN), network professionals must adapt to a paradigm where automation and programmability are the norm.
How Automation Shapes the Future of Networking
- Reduced Complexity: Automation abstracts complex network configurations, making them easier to manage.
- Faster Innovation: Programmable networks adapt quickly to changing business requirements.
- Enhanced Security: Automated compliance checks and vulnerability assessments reduce security risks.
- Cost Savings: Streamlined operations and reduced human errors translate to significant cost benefits.
