About Juniper Automation and DevOps, Associate (JNCIA-DevOps) certification

Recommended Course: Introduction to Junos Platform Automation and DevOps (IJAUTI)

Introduction to Junos Platform Automation and DevOps (IJAUTI) is a fundamental course that’s related to the aforementioned JN0-221 exam. It is suitable for all individuals willing to strengthen their skills and ability to configure or monitor devices featuring the Junos OS. As part of the basic training prerequisites, candidates enrolling in this program must first satisfy the following requirements:

  • Have basic knowledge of computer networking concepts
  • Be proficient with the TCP/IP protocol suite and the OSI model

When it comes to the course content, this 3-day program will help candidates establish a strong mastery of automation concepts and gain the skills needed to work with DevOps automation tools, technologies, and protocols. Through this training, learners will get vital hands-on experience with the languages and tools commonly associated with automating the Junos OS platform within a DevOps environment.

Also, this course will focus on vital Python concepts, PyEZ, REST API, and Ansible, as well as their roles when automating Junos. Like many Juniper study options, the content of this training is well distributed to give candidates a clear overview of what they will be covering every day. Day one starts with the introduction including an outline of the Junos OS, DevOps, and the Junos automation stack. Here, candidates should understand the benefits of DevOps, traffic processing, basic configuration tasks, and interface types, among other topics.

Then, students will learn the details of XPath and XML, XML API and NETCONF, and JSON along with YAML. This stage also introduces candidates to Python and Ansible. It should be stated that the second module of your Juniper JN0-221 exam training has intense requirements, combining online sessions in the form of a series of lectures with vital hands-on labs.

Lastly, the instructors will focus their attention on two major topics. They will introduce the Junos PyEZ and then will conclude with the Junos REST API. Again, you will get some practical skills in these areas by completing the tasks in lab environments. You may want to visit the Juniper official training page to find out more details about this course before registering for your JN0-221 exam.
