Exam-day tips

  • Use JN0-352-era materials; JN0-351 resources may miss updated blueprint content.
  • Know Junos route preference values and how BGP path selection works on Junos.
  • Be able to interpret show spanning-tree and show ospf neighbor output.
  • High-availability features (GRES, NSR, ISSU) are commonly confused; know what each protects.
  • Juniper does not publish the passing score or objective weights, so cover every listed objective rather than gambling on a few.
