  • Know how high-availability features map to design goals.
  • Understand trade-offs between Layer 2 and Layer 3 campus designs.
  • Expect security design questions on segmentation and zone placement.
  • Juniper does not publish the passing score or objective weights, so cover every listed objective rather than gambling on a few.
