End-to-end confidentiality requires securing both client-to-ALB and ALB-to-target legs when policy demands. In this situation, DNS name resolution is not a transport security control and cannot guarantee TLS use. The proposed change does not ensure hTTP access is denied and supported HTTPS requests receive validated content.

Certificate validity does not itself prevent negotiation of legacy TLS versions or cipher suites. In this situation, DNS name resolution is not a transport security control and cannot guarantee TLS use. The proposed change does not ensure hTTP access is denied and supported HTTPS requests receive validated content.

Load-balancer TLS termination could change where mutual authentication occurs. In this situation, DNS name resolution is not a transport security control and cannot guarantee TLS use. The proposed change does not ensure hTTP access is denied and supported HTTPS requests receive validated content.

CDN access logs can distinguish edge-visible request patterns from only origin server events. It does not directly achieve the required result: the delivered flow records include the selected extended fields and support flag-based filtering. The constraint is that default flow formats may omit the extra context needed to distinguish transport behavior.

Mirroring supports packet-level inspection, unlike flow logs that summarize connection metadata. In this situation, default flow formats may omit the extra context needed to distinguish transport behavior. The proposed change does not ensure the delivered flow records include the selected extended fields and support flag-based filtering.

Alarm state depends on time-window evaluation and missing-data policy, not merely one isolated datapoint. The needed control instead targets VPC Flow Logs custom format supports additional record fields for richer flow analysis; it succeeds when the delivered flow records include the selected extended fields and support flag-based filtering.

Managing many peer connections can outweigh TGW operating costs at high network scale. It does not directly achieve the required result: the vendor reaches the API privately but cannot route to unrelated provider hosts. The constraint is that service-level private connectivity avoids exposing unrelated provider address ranges to consumers.

Target discovery must follow workload life cycle to avoid forwarding to stopped or obsolete tasks. The needed control instead targets privateLink service endpoints can limit network exposure to the published provider service; it succeeds when the vendor reaches the API privately but cannot route to unrelated provider hosts.

High-performance fabric semantics differ from ordinary TCP service traffic or generic additional ENIs. That adjustment does not address the controlling condition: service-level private connectivity avoids exposing unrelated provider address ranges to consumers. Verify the vendor reaches the API privately but cannot route to unrelated provider hosts.

TCP flow routing and HTTP path matching are separate service capabilities. The decisive technical distinction is gateway Load Balancer endpoints can provide cross-VPC appliance connectivity when route tables are configured symmetrically; an endpoint alone does not alter routing; both forward and return paths must traverse the inspection architecture.

A conventional bare TCP listener is not interchangeable with the GENEVE appliance data path. The reported evidence instead concerns gateway Load Balancer endpoints can provide cross-VPC appliance connectivity when route tables are configured symmetrically: an endpoint alone does not alter routing; both forward and return paths must traverse the inspection architecture.

Internal scheme and security-group rules jointly prevent direct public listener exposure. That property alone cannot account for the reported symptom; an endpoint alone does not alter routing; both forward and return paths must traverse the inspection architecture.

Configuration-based path analysis can identify blockers without requiring production application packet capture. The needed control instead targets VPC Traffic Mirroring can copy selected packet traffic to supported network inspection targets; it succeeds when the analyzer receives expected packet copies for the scoped interface and filters.

Alarm state depends on time-window evaluation and missing-data policy, not merely one isolated datapoint. The needed control instead targets VPC Traffic Mirroring can copy selected packet traffic to supported network inspection targets; it succeeds when the analyzer receives expected packet copies for the scoped interface and filters.

Default flow formats may omit the extra context needed to distinguish transport behavior. In this situation, mirroring supports packet-level inspection, unlike flow logs that summarize connection metadata. The proposed change does not ensure the analyzer receives expected packet copies for the scoped interface and filters.

Layer-seven WAF scope cannot act as a stateful inter-VPC TCP firewall for non-HTTP traffic. The reported evidence instead concerns stateful firewalls in a transit architecture require symmetric paths through the correct inspection endpoints: asymmetric routing sends the reverse packets through missing firewall state or around inspection controls.

Packets not sent to the stateful engine cannot be filtered by its configured stateful rules. The reported evidence instead concerns stateful firewalls in a transit architecture require symmetric paths through the correct inspection endpoints: asymmetric routing sends the reverse packets through missing firewall state or around inspection controls.

Simply creating an endpoint does not redirect network packets onto the appliance data path. The decisive technical distinction is stateful firewalls in a transit architecture require symmetric paths through the correct inspection endpoints; asymmetric routing sends the reverse packets through missing firewall state or around inspection controls.

IaC syntax validity does not establish compliance with organizational network policy. In this situation, high-level constructs can create network defaults that differ from a specific compliance design if inputs are vague. The proposed change does not ensure synthesized subnets use only the planned gateway and NAT paths without unauthorized public routes.

An IaC dependency graph cannot create a missing external identifier from an arbitrary string. That adjustment does not address the controlling condition: high-level constructs can create network defaults that differ from a specific compliance design if inputs are vague. Verify synthesized subnets use only the planned gateway and NAT paths without unauthorized public routes.

Subnets and network interface IDs are scoped to a VPC and Region, not globally interchangeable. In this situation, high-level constructs can create network defaults that differ from a specific compliance design if inputs are vague. The proposed change does not ensure synthesized subnets use only the planned gateway and NAT paths without unauthorized public routes.

Mutual TLS verifies client certificate identity separately from the listener's server certificate. The decisive technical distinction is IPsec protects a network tunnel but does not replace application-layer TLS identity verification; network peer authentication cannot independently prove that a particular HTTPS hostname is the intended app server.

Load-balancer TLS termination could change where mutual authentication occurs. The reported evidence instead concerns IPsec protects a network tunnel but does not replace application-layer TLS identity verification: network peer authentication cannot independently prove that a particular HTTPS hostname is the intended app server.

HTTPS transport encryption does not establish server identity when its certificate is invalid or expired. For the stated conditions, network peer authentication cannot independently prove that a particular HTTPS hostname is the intended app server. The more specific mechanism is IPsec protects a network tunnel but does not replace application-layer TLS identity verification.

Split-horizon configuration can intentionally prevent public answers from leaking into an internal namespace. For the stated conditions, an internal name pointing at a public resource does not remove public network exposure. The more specific mechanism is DNS alias records influence name resolution but do not change the load balancer's network-facing scheme.

Private zone visibility follows VPC associations rather than AWS organization membership alone. The decisive technical distinction is DNS alias records influence name resolution but do not change the load balancer's network-facing scheme; an internal name pointing at a public resource does not remove public network exposure.

A reachable resolver can correctly answer NXDOMAIN when no matching record exists. The reported evidence instead concerns DNS alias records influence name resolution but do not change the load balancer's network-facing scheme: an internal name pointing at a public resource does not remove public network exposure.

Private circuit establishment alone does not provision vendor encryption or control-plane overlays. The decisive technical distinction is a public VIF uses publicly advertised AWS prefixes, not VPC private-IP routing semantics; interface class determines the reachable addressing domain rather than its physical circuit speed.

Tunnel health alone does not create a routing advertisement for an omitted customer network. The reported evidence instead concerns a public VIF uses publicly advertised AWS prefixes, not VPC private-IP routing semantics: interface class determines the reachable addressing domain rather than its physical circuit speed.

An active VIF and BGP session do not automatically override VPC subnet forwarding decisions. For the stated conditions, interface class determines the reachable addressing domain rather than its physical circuit speed. The more specific mechanism is a public VIF uses publicly advertised AWS prefixes, not VPC private-IP routing semantics.

Signing a hosted zone alone does not establish validation if the parent delegation lacks the needed DS chain. For the stated conditions, geolocation routing is a location-matching policy, not a latency-measurement algorithm. The more specific mechanism is Route 53 geolocation routing can choose a record by a client's resolved geographic location.

VPC DNS does not automatically forward an arbitrary private namespace to on-premises without a rule. The decisive technical distinction is Route 53 geolocation routing can choose a record by a client's resolved geographic location; geolocation routing is a location-matching policy, not a latency-measurement algorithm.

Simple routing alone does not make Route 53 suppress failed records based on application health. That property alone cannot account for the reported symptom; geolocation routing is a location-matching policy, not a latency-measurement algorithm.
