JNCIA-DevOps study guide
JNCIA-DevOps · Work through your exam, one topic at a time.
The JNCIA-DevOps credential is listed in our catalog as the Juniper Networks Certified Associate DevOps certification, an associate-level qualification aimed at network engineers who are moving from manual device administration toward programmatic, repeatable workflows. It is intended for people who already understand basic Junos configuration and now want to demonstrate that they can automate, template, and integrate network operations using code, version control, and APIs. Because the official certification page could not be retrieved on 2026-11-06 (the URL returned an HTTP 404 error page), we cannot state the exam length, question count, passing score, fee, delivery format, retake rules, or validity period, and the domain weights shown on this page are an unverified placeholder. Treat every numeric detail as unconfirmed until an authoritative Juniper or HPE certification source is available, and verify before booking. The JNCIA-DevOps study guide has 5 sections and about 1,725 words.
01Automation and Scripting
The Automation and Scripting domain checks whether you can read, write, and reason about small automation programs and the data they exchange. Expect Python fundamentals, JSON/YAML/XML handling, Jinja2 templating, and Junos-specific automation with PyEZ, SLAX, and XSLT.
324 words, about 2 min02DevOps Culture and Practices
This domain tests the vocabulary and behaviors that make automation sustainable: CALMS, feedback loops, version control, collaboration, and blameless learning. Questions often probe the difference between a toolchain and an operating culture.
350 words, about 2 min03Infrastructure as Code and Configuration Management
This domain tests declarative desired-state management, idempotency, drift, and Junos configuration semantics. You must know how tools such as Ansible and templates enforce a documented state rather than ad hoc CLI edits.
372 words, about 2 min04Continuous Integration and Continuous Delivery
This domain tests pipeline design, automated validation, deployment strategies, and rollback. Network pipelines must validate configuration before it reaches production devices.
352 words, about 2 min05Network Automation with Junos and APIs
This domain tests how to programmatically read and change Junos state using NETCONF, REST, XML, YANG, and telemetry interfaces. Junos supports NETCONF over SSH (default TCP 830), the Junos XML API, and a REST API over HTTP/HTTPS.
