Required transport sessions reach healthy targets through stable regional load-balancer entry addresses. That result supports Network Load Balancer TCP UDP and static addresses but does not establish the requested networking outcome here. Instead verify: Clients authenticate the intended public endpoint and regulated traffic remains encrypted on the backend segment where required. Scenario: A compliance review discovers that the ALB terminates TLS but forwards plaintext HTTP to backends over a network segment required to be encrypted.

Configure VPC Traffic Mirroring with a supported source ENI and destination for packet-oriented analysis when detailed headers are required. This choice relates to VPC Traffic Mirroring packet-level design, not the complementary response and evidence pair for the case. Prefer: Use VPC Flow Logs at the appropriate VPC, subnet or network-interface scope to summarize connection metadata and distinguish ACCEPT/REJECT results. Confirm with: Inspect logging attachment scope, aggregation interval, source and destination fields, action, log status and delivery destination. Scenario: A central operations team cannot diagnose a rejected database connection because Flow Logs were enabled on another subnet instead of the affected ENI.

Inspect metric dimensions, statistic, evaluation windows, missing-data treatment, alarm actions and correlated service health.

Scenario: A public platform routes api.example.com and shop.example.com to different backend pools but was provisioned with a layer-four listener lacking host-based rules.

Inspect and enforce approved VPC egress or transit traffic with AWS Network Firewall stateful and stateless rule groups and appropriate route insertion. That approach addresses AWS Network Firewall stateful egress filtering instead of the principal requirement here. Deploying a firewall policy alone does not force packet paths through its endpoints; route tables and stateless/stateful processing order matter. The better fit for this scenario is: Build appropriately scoped custom VPC Flow Log records including relevant packet and interface fields to correlate network policy enforcement. Scenario: Analysts cannot distinguish original packets from a transformed flow because their custom format omits packet source and destination fields.

Use supported CloudWatch Logs metric filters, alarms and event processing to alert on network policy violations with sufficient context and tuning. That approach addresses CloudWatch log metric filters and cross-source alert correlation instead of the principal requirement here. A filter matching one API event is not a packet firewall; log processing and alert signals must be tested against actual source logs and missing-data behavior. The better fit for this scenario is: Build appropriately scoped custom VPC Flow Log records including relevant packet and interface fields to correlate network policy enforcement. Scenario: Analysts cannot distinguish original packets from a transformed flow because their custom format omits packet source and destination fields.

Use supported VPC endpoint policies, identity policies and SG restrictions to govern access to AWS services without unrestricted internet traversal. That approach addresses Endpoint policies and least-privilege private egress instead of the principal requirement here. An endpoint policy complements IAM and resource-based policies; an endpoint existing does not grant every caller access to every AWS API action. The better fit for this scenario is: Build appropriately scoped custom VPC Flow Log records including relevant packet and interface fields to correlate network policy enforcement. Scenario: Analysts cannot distinguish original packets from a transformed flow because their custom format omits packet source and destination fields.

Scenario: An engineer sees REJECT records for outbound HTTPS from an instance and needs to distinguish subnet ACL policy from an absent application response.

Separate viewer cache-key dimensions from values forwarded to origins, and include only request values that change the actual representation. This choice relates to CloudFront cache key and origin request policies, not the complementary response and evidence pair for the case. Prefer: Use AWS Global Accelerator static anycast IPs with regional endpoint groups when global clients require managed network routing and fast endpoint failover.

This choice relates to Private hosted zones and VPC associations, not the complementary response and evidence pair for the case. Prefer: Use AWS Global Accelerator static anycast IPs with regional endpoint groups when global clients require managed network routing and fast endpoint failover. Confirm with: Inspect listener ports, endpoint weights, health status, client path, AWS edge entry and endpoint-group traffic dials.
