Juniper Networks Junos Essentials: Networking Fundamentals from Skillsoft

Online, Self-Paced

Configuring Junos OS devices requires a thorough understanding of networking fundamentals, and this course is a primer in that understanding. It covers the fundamentals of networking, including the OSI network model, the routing and switching functions, and data-link and IP addressing. This course is one of a series of Skillsoft courses that cover the objectives for Juniper Networks exam JN0-102. This exam completes the requirement for the certification Juniper Networks Certified Associate - Junos (JNCIA-Junos).
