Exam-day tips

  • Design questions favor answers that meet business, cost and resiliency constraints together.
  • Know cloud interconnect options (VPN vs dedicated circuits) and their trade-offs.
  • Expect performance-based diagrams where you place components or fix routing.
  • There is no scaled score; prepare evenly across all four domains.
  • Use the 165 minutes; there is enough time to analyze long exhibits.
