Certification & Exam

One training course, one exam
Achieving Cisco Certified DevNet Associate certification proves your skills in developing and maintaining applications built on Cisco platforms. To earn DevNet Associate certification, you pass one exam that covers the fundamentals of software development and design for Cisco platforms

The DevNet Associate Exam v1.0 (DEVASC 200-901) exam is a 120-minute exam associated with the Cisco Certified DevNet Associate certification. This exam tests a candidate’s knowledge of software development and design including understanding and using APIs, Cisco platforms and development, application development and security, and infrastructure and automation. The course, Developing Applications and Automating Workflows Using Cisco Core Platforms, helps candidates to prepare for this exam.

The following topics are general guidelines for the content likely to be included on the exam. However, other related topics may also appear on any specific delivery of the exam. To better reflect the contents of the exam and for clarity purposes, the guidelines below may change at any time without notice.
