Which components are a part of the OCI Identity and Access Management service?

Detailed Answer in Step-by-Step Solution: Objective: Identify IAM components in OCI. Understand IAM: Manages access via policies, groups, etc. Evaluate Options: A: Policies—Core IAM component—correct. B: Subnets—Networking, not IAM. C: Instances—Compute, not IAM. D: VCN—Networking, not IAM. Reasoning: Only A is an IAM element—others are resources. Conclusion: A is correct. OCI documentation states: “IAM includes components like policies (A), groups, and compartments to control resource access.” B, C, and D are infrastructure, not IAM—only A fits per OCI’s IAM framework. : Oracle Cloud Infrastructure IAM Documentation, "IAM Components".
