Study Strategy
Allocate time by domain weight: Domain 4 at 30% deserves the most attention. Domains 2, 3, and 5 at 20% each are equally weighted. Domain 1 at 10% requires the least time.
Focus on Google Cloud content: Multiple sources identify Google Cloud integration as the most challenging area, since it is newer and less widely deployed (Zaballa).
Think in scenarios: This is a Professional-level exam. Questions test architectural decision-making, not just recall. Understand trade-offs: VPN vs. FastConnect, Autonomous DB vs. Exadata, Azure onboarding vs. Google Cloud onboarding.
Hands-on practice: Use OCI Free Tier to explore VCN networking, DRG configuration, and Identity Domains.
