What is Oracle-recommended best practice during implementation when creating an FDI instance on the OCI console?

• A. Create separate compartments for each FDI instance type. For example, a compartment for the test FDI instance and another for the production FDI instance.
• B. Create separate compartments for each environment (test and production).
• C. Use compartments only by region.
• D. Do not use compartments.

Answer: (B)

Compartments are a governance boundary in OCI that lets you control access, policies, and budgeting for groups of resources. The best practice when implementing an FDI instance is to create separate compartments for each environment, such as test and production. This separation enables you to apply different IAM policies, budgets, monitoring, and audit trails to each environment, so changes in one environment won’t affect the other. It also makes it easier to assign the right teams to the right environment and to track costs and compliance per environment.

Using compartments by environment supports proper isolation and risk management. Creating compartments by instance type or by region isn’t the intended way to enforce environment-level governance, and skipping compartments removes essential control and visibility.
