DEVASC v1.0 - Developing Applications and Automating Workflows using Cisco Core Platforms

The Developing Applications and Automating Workflows Using Cisco Core Platforms (DEVASC) v1.0 course helps you prepare for Cisco DevNet Associate certification and for associate-level network automation engineer roles. You will learn how to implement basic network applications using Cisco platforms as a base, and how to implement automation workflows across the network, security, collaboration, and computing infrastructure. The course gives you hands-on experience solving real-world problems using Cisco Application Programming Interfaces (APIs) and modern development tools. This course helps you prepare to take the 200-901 DevNet Associate (DEVASC) exam.

After taking this course, you should be able to:

• Describe the importance of APIs and the use of version control tools in modern software development
• Describe common processes and practices used in software development
• Describe options for organizing and constructing modular software
• Describe HTTP concepts and how they apply to network-based APIs
• Apply Representational State Transfer (REST) concepts to the integration with HTTP-based APIs
• Describe Cisco platforms and their capabilities
• Describe programmability features of different Cisco platforms
• Describe basic networking concepts and interpret simple network topology
• Describe the interaction of applications with the network and tools used for troubleshooting issues
• Apply concepts of model-driven programmability to automate common tasks with Python scripts
• Identify common application deployment models and components in the development pipeline
• Describe common security concerns and types of tests, and utilize containerization for local development
• Utilize tools to automate infrastructure through scripting and model-driven programmability

This class includes lecture sections and self-study sections. In instructor-led classes, lectures are delivered in real-time, either in person or via video conferencing. In e-learning courses, the lectures are on recorded videos. In both versions, you will need to review self-study sections on your own before taking the certification exam.
