Developing Applications and Automating Workflows Using Cisco Core Platforms v1.0

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
• Gain a foundation in the essentials of applications, automation, and Cisco platforms
