An inference service searches sensitive documents.
Do not expose data directly to the public network.
Choose two designs.
Hint 1: Focus on the requirement Separate inference, retrieval, and data networks, then control outbound paths and keep identity and encryption as independent layers.
Hint 2: Key terms Review network segmentation and egress control.
Network segmentationDividing workloads or data layers into separate network boundaries and paths.
Egress controlRestricting traffic leaving a workload by destination, port, protocol, or route.
ReachabilityThe network paths through which one component can connect to another.
Security groupA stateful virtual firewall controlling allowed traffic for network interfaces. × Incorrect Separate inference, retrieval, and storage paths and review security groups, egress controls, network logs, encryption, and IAM together.
Detailed explanation A Incorrect Network isolation makes IAM and encryption unnecessary
Defense in depth remains required.
B Incorrect Expose inference to the internet with every port open
The attack surface expands.
C Correct Review security groups, egress, network logs, encryption, and IAM
Multiple boundaries are audited.
D Correct Separate inference, retrieval, and storage into necessary subnets and endpoints
Unneeded reachability is reduced.
