JNCIA-Junos: configuration and operations

Objectives and progression

Initial course with seven lessons and 33 original decisions in fictional APS and IT-project contexts. Internal assessment of 19 decisions in 45 minutes. J-Web, software architecture, authorized credential recovery, RPF, and configuration labs need further depth. JN0-106 effective since 2026-04-06 with Junos OS 21.2 as the published exam baseline. Since 2026-09-15 the program is named HPE Networking Certification Program. This preparation is independent.

Audience: Networking, APS, and technical coordination professionals beginning Junos operations.

Prerequisites: IP and networking basics, command reading, and an isolated practice lab. No prior certification is required.
