Achieving Cisco Certified DevNet Expert certification validates your expert knowledge and proficiency in network automation, programmability, and secure automation tools.
To earn Cisco Certified DevNet Expert certification, you pass two exams: a qualifying exam that covers core software and automation development and design for Cisco platforms as well as a hands-on lab exam that covers software-driven network automation solutions through the entire network lifecycle, from designing and deploying to operating and optimizing.
Steps To CCIE DevNet Certification
To earn CCIE DevtNet, you pass two exams: a qualifying exam and hands-on lab exam:
Step 1: For Qualifying exam, pass the below recommended training and exam:
Developing Applications using Cisco Core Platforms and APIs (350-901 DEVCOR)
Step 2: Pass the Lab exam:
DevNet Expert-level lab (8-hour lab)
