You are designing an OCI VCN for a new application with the following requirements: The application servers in a private subnet must be able to…

Requirements: Outbound internet access, no inbound exposure, and private OCIR access.
Option A: Internet Gateway allows inbound traffic, violating the no-exposure rule—incorrect.
Option B: NAT Gateway enables outbound-only internet access, but Internet Gateway adds inbound exposure—incorrect.
Option C: NAT Gateway provides outbound internet access without inbound exposure; Service Gateway enables private OCIR access—correct.
Option D: DRG is for external networks, not internet/OCIR access; Internet Gateway exposes servers—incorrect. Conclusion: Option C satisfies all requirements. Oracle states: "Use a NAT Gateway for outbound internet access from private subnets without inbound connectivity. Use a Service Gateway for private access to OCI services like OCIR." This supports Option C.
