OCI 1Z0-1072-25 exam guide covering tenancy design, networking, resilience, cost, and service placement decisions.
1Z0-1072-25 is an architecture-and-placement exam. Strong answers usually come from putting the right control or service at the right layer rather than just picking the most powerful option.
Compartment: A logical boundary used to organize, isolate, and govern OCI resources.
Gateway: An OCI networking attachment that gives a VCN path to another network scope such as the internet or Oracle services.
What this guide emphasizes
tenancy, IAM, and compartment strategy
VCN design, subnet placement, routing, and edge decisions
compute, storage, database, and load-balancing selection
high availability, backup, observability, and architectural tradeoffs
What strong answers usually do
decide first whether the problem is identity, network, service-selection, or resilience
separate compartment and IAM scope from network-control scope
place public edge and private tiers deliberately instead of mixing responsibilities
choose the simplest architecture that still satisfies exposure, resilience, and recovery requirements
