About Course

 
Duration: 5 days

*Instructor-led Classroom Training &
*Instructor-led Online / Hybrid Training

The DevNet certification program is the first of its kind at Cisco and validates the skills of software developers, DevOps engineers, automation specialists and other software professionals. The program certifies new key technical competencies for a new breed of IT professionals and empowers organizations to harness the potential of applications, automation and infrastructure for the network, IoT, DevOps and the cloud.

Certification requires an exam that tests your knowledge of software development and design, including:

  • Understanding and using APIs
  • Cisco platforms and development
  • Application development and security
  • Infrastructure and automation
