Exam-day tips

  • Know which automation tool talks to which Junos interface (NETCONF, REST, CLI).
  • Be able to read short PyEZ and Ansible snippets and predict the result.
  • Know YAML syntax rules (indentation, lists vs dictionaries) precisely.
  • Understand the difference between XML RPCs for operational commands and configuration loading.
  • Juniper does not publish the passing score or objective weights, so cover every listed objective rather than gambling on a few.
