JNCIA DevOps Certification
The JNCIA-DevOps (Juniper Networks Certified Internet Associate – Automation and DevOps) is an associate-level certification in Juniper Networks’ Certification Program[1][2]. It validates the holder’s expertise in using scripting tools and languages to automate devices and networks that operate with the Juniper Network Junos operating system.
Key aspects of the JNCIA-DevOps certification include:
- It is designed for entry-level admin and networking professionals with at least one year’s experience and a basic understanding of Junos automation tools and best practices.
- The certification exam (JN0-221) is a 90-minute test consisting of 65 multiple-choice questions.
- It covers topics such as DevOps concepts, automation tools, and their application to Juniper devices and solutions.
- The certification is valid for three years and can be recertified by passing any JNCIA exam or a specialist-level exam.
- It serves as a prerequisite for the specialist-level JNCIS-DevOps certification.
The JNCIA-DevOps is valuable for professionals looking to validate their skills in Juniper Networks automation and DevOps practices, whether they work for end-user enterprises or service/integration firms.

This focus on user-friendly solutions and technological advancements has made Juniper a preferred choice for enterprises and service providers seeking robust, scalable, and future-proof networking solutions.
Juniper Devops Online Course
There are a few places to learn the JNCIA DevOps curriculum. Juniper have a course, Udemy have a few, CBT Nuggets have one but I think it might be a bit out of date now?
What is NetConf?
NETCONF (Network Configuration Protocol) is a network management protocol that provides mechanisms for configuring and managing network devices in an efficient and standardized way. It is defined by the IETF (Internet Engineering Task Force) in RFC 6241 and operates over a reliable transport protocol, such as SSH, to enable secure and consistent management of devices like routers, switches, firewalls, and other network equipment. NETCONF allows network administrators to automate configuration tasks, monitor network status, and manage resources with a clear set of operations, such as retrieving data, changing configurations, and committing or rolling back changes.
NETCONF is designed to be extensible, allowing it to support various device types and configurations. It uses XML as the encoding format for both the configuration data and the messages exchanged between the network management system (NMS) and the devices. By using devops principles and providing capabilities like transaction-based changes, rollback, and configuration validation, NETCONF ensures that network configurations can be modified with minimal risk of disruption. This makes it an essential tool for automating network management in complex, large-scale environments where consistency and error-free configuration are critical. Additionally, NETCONF often works alongside other technologies like YANG (Yet Another Next Generation) to define the data models used for configuration, making it more versatile and adaptable to evolving network needs.
