DEVASC: Developing Applications and Automating Workflows Using Cisco Core Platforms

The Developing Applications and Automating Workflows Using Cisco Core Platforms (DEVASC) 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 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 will help you:

• Take advantage of the network when you implement applications to fulfill business needs
• Gain a foundation in the essentials of applications, automation, and Cisco platforms
• Prepare for the 200-901 DevNet Associate (DEVASC), which earns Cisco Certified DevNet Associate certification

What's Included

• Official Cisco courseware
• Remote lab access

Course Objectives
