What you’ll learn in this course.

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 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. By passing this exam, you earn Cisco Certified DevNet Associate certification. The 200-901 DEVASC exam goes live on February 24, 2020

Course duration

Instructor-led training: 5 days in the classroom and 3 days of self-study

How you’ll benefit

This course will help you:

• Take advantage of the network when you implement applications to fulfill business needs
