Which service can be used in OCI to automate the creation of interconnect-related infrastructure?

Question breakdown

Tests

Automate multicloud interconnect infrastructure with IaC

Difficulty

Easy

Key idea: OCI Resource Manager is the managed Terraform service that provisions networking components such as DRGs, FastConnect virtual circuits and route tables repeatably.

How to reach the answer

1. The clue is 'automate the creation' of infrastructure, which signals infrastructure as code.
2. Identify the OCI service that runs Terraform as a managed service: Resource Manager.
3. Confirm it can create interconnect pieces (DRG, VCN attachments, FastConnect, routing, security rules).
4. Eliminate services with unrelated purposes (API management, interactive shell, secrets).

Each option

• AIncorrect. API Gateway publishes and secures APIs and does not provision network infrastructure.
• BCorrect. Resource Manager runs Terraform stacks that create and manage interconnect resources consistently.
• CIncorrect. Cloud Shell is an interactive browser terminal; you could run scripts there, but it is not an automation service.
• DIncorrect. Vault stores keys and secrets, not infrastructure definitions.

Common trap: Cloud Shell includes Terraform and the CLI, so it can seem like an automation tool, but it is only a manual workspace without state management or job orchestration.

In practice: Architects build Resource Manager stacks that stand up DRGs and FastConnect or Azure/GCP interconnect circuits identically across dev, test and prod.

Remember: Automating OCI infrastructure means Resource Manager (managed Terraform).
