For IT leaders

What IT leaders need to know before assigning this course

Manual Juniper network operations create change risk, slow deployments, and make it harder for teams to standardize how infrastructure is managed. This 5-hour, 6-minute JNCIS-DevOps course is a focused assignment for network engineers, network automation engineers, and infrastructure specialists who already work in the Junos ecosystem and need specialist-level automation skills tied to the JN0-423 exam.

IT Directors and Team Leads can use it to move experienced practitioners from ad hoc device management toward repeatable automation practices. The course covers Junos automation architecture, streaming telemetry with gRPC/gNMI, Ansible fundamentals and Junos-focused Ansible workflows, more complex playbook creation, and data models. For change management, assign it to engineers responsible for network operations standards before asking them to modify production automation. CBT Nuggets Playlists can sequence this with prerequisite Junos training, while Team Reporting helps Training Managers track completion across the assigned team.

Team Impact

How this training helps your team succeed

IT teams complete this training to improve consistency in Juniper automation work and reduce reliance on manual, device-by-device operations. The course maps to practical scenarios network teams face when standardizing Junos automation and telemetry.

  • Standardize Junos automation decisions: Teams learn the Junos automation architecture so engineers share a common model for how automation fits into network operations.
  • Improve operational visibility: Streaming telemetry with gRPC/gNMI helps teams understand modern approaches to collecting network data.
  • Build repeatable automation workflows: Ansible fundamentals, architecture, and advanced Junos usage support more consistent configuration and operational tasks.
  • Prepare for scalable automation design: Complex playbooks and data models help teams move beyond one-off scripts toward reusable automation patterns.

Frequently Asked Questions

Are DevOps and Automation basically the same thing?

Not exactly, no. Automation is the practical act of using tools like Ansible, Python, PyEZ, and Nornir to handle repeatable network tasks (e.g., pushing configs, validating changes, collecting telemetry, or managing inventory). DevOps is the larger operational approach to work: building repeatable processes, testing changes safely, improving collaboration, and making infrastructure easier to scale over time. In a Junos environment, automation is often how the work gets done, while DevOps is how the team thinks about doing it reliably. This course, and the JNCIS-DevOps cert, is useful because it teaches both the tools and the operational mindset in a real networking context.

Can I learn DevOps in 3 months?

You can definitely build a strong DevOps and network automation foundation in 3 months, especially if you already have solid networking experience. What matters is learning the right progression: first understand how your devices and configs are structured, then move into automation workflows with tools like Ansible, Python, inventory management, and validation. For Junos professionals, this course is especially relevant because it focuses on how automation works in real networks. Three months is realistic for learning the concepts and building hands-on confidence. Becoming good at production automation takes longer, but a few months is enough to become effective and start automating the parts of your environment that don’t need to stay manual.

Which is harder, JNCIA-DevOps or Cisco CCNP Automation?

It depends on your background. JNCIA-DevOps focuses on automation in Junos environments using tools like Python, PyEZ, and basic APIs, so it's more approachable if you're already comfortable with Juniper devices. Cisco CCNP Automation, on the other hand, spans multiple domains, and often feels harder because it covers a broader mix of APIs, automation, and software development concepts. JNCIA-DevOps builds on top of existing networking experience, while the DevNet shifts focus toward a developer mindset. Neither is easy, but JNCIA-DevOps will feel more focused and practical for Juniper network engineers.

What does JNCIS stand for?

JNCIS stands for Juniper Networks Certified Internet Specialist. It’s Juniper’s specialist-level certification tier, sitting above JNCIA (associate) and below JNCIP (professional) and JNCIE (expert) levels. At the specialist level, the expectation is that you already understand Junos fundamentals and real-world networking operations, and now you’re building deeper expertise in a focused area. In the case of JNCIS-DevOps, that focus is on network automation and scalable operations. This course prepares you to use tools like Ansible, PyEZ, Python, Nornir, telemetry, and YANG models on Junos devices and networks, and to take the JNCIS-DevOps exam (JN0-423). In practical career terms, that signals you’re moving beyond manual administration into automation-driven network engineering.

What is the difference between JNCIA DevOps and Cisco Automation certifications?

The biggest difference is depth and ecosystem focus. JNCIA-DevOps is the entry point into Juniper automation, covering the basics of PyEZ, Python, APIs, and Junos workflows. This JNCIS-DevOps course is the next step and goes much deeper into Ansible, Nornir, telemetry, YANG, and large-scale automation. Cisco CCNA/CCNP Automation is broader across Cisco’s ecosystem and often leans more into APIs, programmability, and cross-platform integrations beyond just networking. If your environment is Junos-heavy, the Juniper path will probably feel more useful because it maps to real operational tasks on Juniper devices. CCNA/CCNP Automation is excellent too, but it’s broader and often less tied to one network operating model.
