JN0-423: The New Juniper Automation and DevOps Specialist Exam
Juniper Networks confirmed that the JN0-422 Automation and DevOps Specialist exam retired on Oct. 5, 2025. The very next day, JN0-423, or the new Juniper Automation and DevOps Specialist exam, took its place.
Juniper Automation is all about using Juniper Networks’ tools to streamline how networks are built and managed. It helps engineers cut down on repetitive tasks, improve consistency from initial planning through day-to-day operations, and deliver a more reliable experience for customers.
Why the Change?
Certifications don’t stay the same forever. DevOps has moved quickly, and the JN0-422 exam is simply out of date. Tools like Python, Ansible, and Salt are now standard in day-to-day work. Juniper reflects those changes with the launch of JNO-423.
What to Expect with the New JN0-423
The JN0-423 exam won’t throw everything out. It builds on the same foundation, but the emphasis changes. You can expect the following:
Python scripting and Juniper’s PyEZ
Ansible for playbooks and workflows
Salt for configuration management
More content around CI/CD pipelines and orchestration
If you are already working toward JN0-422, don’t think your study time was wasted. Much of what you’ve learned will still be relevant. JN0-423 simply updates the exam to match current industry practice.
Skills You’ll Need for the New JNO-423
Candidates should be comfortable with:
Writing and troubleshooting Python code
Automating Junos devices with PyEZ
Using Ansible for network automation
Applying Salt in practice
Understanding DevOps workflows and CI/CD pipelines
Hands-on practice is important. This isn’t just about knowing commands; it’s about using them in real-world environments.
Why This Juniper Automation Exam Update Matters
Networking and DevOps have become tightly connected. Employers want engineers who can automate tasks, manage infrastructure at scale, and plug into DevOps processes. Certifications like JN0-423 show you have those skills.
By moving forward with JN0-423, Juniper is keeping the JNCIS-DevOps certification current and valuable in the market.
Planning Your Next Step
The retirement of the old Juniper Automation and DevOps Specialist exam and the launch of JN0-423 is a normal update, not a surprise. This certification remains a solid move for building networking and DevOps careers.
