Mutual TLS verifies client certificate identity separately from the listener's server certificate. That adjustment does not address the controlling condition: NLB TLS termination is different from a TCP listener passing encrypted data through to targets. Verify client TLS negotiates at the NLB listener with the expected certificate.

End-to-end confidentiality requires securing both client-to-ALB and ALB-to-target legs when policy demands. That adjustment does not address the controlling condition: NLB TLS termination is different from a TCP listener passing encrypted data through to targets. Verify client TLS negotiates at the NLB listener with the expected certificate.

Load-balancer TLS termination could change where mutual authentication occurs. That adjustment does not address the controlling condition: NLB TLS termination is different from a TCP listener passing encrypted data through to targets. Verify client TLS negotiates at the NLB listener with the expected certificate.

A management-plane audit trail attributes configuration changes, unlike aggregated data-plane flow records. The reported evidence instead concerns cloudWatch metric filters and alarms can turn matching log records into thresholded metrics: flow logs need aggregation into a metric before CloudWatch can evaluate counts as an alarm condition.

Network-flow metadata can indicate volume and routing context without revealing encrypted payload contents. The reported evidence instead concerns cloudWatch metric filters and alarms can turn matching log records into thresholded metrics: flow logs need aggregation into a metric before CloudWatch can evaluate counts as an alarm condition.

Observation mode supports tuning before blocking production requests. The reported evidence instead concerns cloudWatch metric filters and alarms can turn matching log records into thresholded metrics: flow logs need aggregation into a metric before CloudWatch can evaluate counts as an alarm condition.

Network-flow metadata can indicate volume and routing context without revealing encrypted payload contents. For the stated conditions, packet mirroring provides payload visibility where allowed, while flow logs provide summarized metadata. The more specific mechanism is traffic Mirroring can copy supported network packet streams for deep security inspection.

Configuration history provides a time series of supported resource states beyond the current console view. The decisive technical distinction is traffic Mirroring can copy supported network packet streams for deep security inspection; packet mirroring provides payload visibility where allowed, while flow logs provide summarized metadata.

An organization policy cannot be assumed effective without checking each targeted resource's compliance state. The decisive technical distinction is traffic Mirroring can copy supported network packet streams for deep security inspection; packet mirroring provides payload visibility where allowed, while flow logs provide summarized metadata.

Rate limits mitigate high-volume application requests based on request attributes, not just TCP handshake state. It does not directly achieve the required result: only instances carrying the approved source security group can reach the database listener. The constraint is that group references bind access to associated workload identities rather than static IP lists.

A broad earlier deny can supersede a later allow despite permissive security groups. It does not directly achieve the required result: only instances carrying the approved source security group can reach the database listener. The constraint is that group references bind access to associated workload identities rather than static IP lists.

Endpoint private addressing does not automatically enforce least-privilege client access. In this situation, group references bind access to associated workload identities rather than static IP lists. The proposed change does not ensure only instances carrying the approved source security group can reach the database listener.

A broad transit route need not divert packets matching a more-specific valid local route. The reported evidence instead concerns a matching Transit Gateway blackhole route drops packets rather than forwarding to an alternate less-specific route: the most specific matching blackhole takes precedence over a broader valid route.

Local VPC propagation into a TGW does not automatically propagate onward over inter-region peering. For the stated conditions, the most specific matching blackhole takes precedence over a broader valid route. The more specific mechanism is a matching Transit Gateway blackhole route drops packets rather than forwarding to an alternate less-specific route.

Peering routes do not permit arbitrary traversal through another VPC's internet or VPN gateway. The decisive technical distinction is a matching Transit Gateway blackhole route drops packets rather than forwarding to an alternate less-specific route; the most specific matching blackhole takes precedence over a broader valid route.

A private DNS record invisible to ACM's validation resolvers cannot prove public domain control. That property alone cannot account for the reported symptom; a signed child zone alone does not prove authenticity to validators without the parent trust chain.

HTTPS transport encryption does not establish server identity when its certificate is invalid or expired. For the stated conditions, a signed child zone alone does not prove authenticity to validators without the parent trust chain. The more specific mechanism is DNSSEC validation depends on parent DS material corresponding to the zone's signing key.

Forwarding alone transports DNS answers and does not guarantee cryptographic integrity validation. For the stated conditions, a signed child zone alone does not prove authenticity to validators without the parent trust chain. The more specific mechanism is DNSSEC validation depends on parent DS material corresponding to the zone's signing key.

A backup tunnel's presence does not guarantee traffic will switch unless routing reacts appropriately. The decisive technical distinction is physical Direct Connect line rate and interface capacity constrain achievable throughput; BGP routes do not increase the actual physical capacity of an undersized circuit.

The virtual interface type determines whether connectivity targets private VPC addresses or public AWS endpoints. That property alone cannot account for the reported symptom; BGP routes do not increase the actual physical capacity of an undersized circuit.

Public VIF traffic uses public AWS addresses even when the physical transport is dedicated. The decisive technical distinction is physical Direct Connect line rate and interface capacity constrain achievable throughput; BGP routes do not increase the actual physical capacity of an undersized circuit.

The load balancer's status can differ from the response produced or not produced by a backend target. It does not directly achieve the required result: network path checks pass while the separate application test identifies the actual service fault. The constraint is that a permitted virtual network path can coexist with a crashed application or failed TLS handshake.

A log disposition identifies a blocked flow but not the precise rule or network layer responsible. The needed control instead targets configuration-based network reachability does not establish application health or protocol correctness end to end; it succeeds when network path checks pass while the separate application test identifies the actual service fault.

Mirroring supports packet-level inspection, unlike flow logs that summarize connection metadata. In this situation, a permitted virtual network path can coexist with a crashed application or failed TLS handshake. The proposed change does not ensure network path checks pass while the separate application test identifies the actual service fault.

Default flow formats may omit the extra context needed to distinguish transport behavior. In this situation, large outliers may have little effect on the mean but violate strict tail-latency service goals. The proposed change does not ensure the p99 graph exposes the spike and allows correlation with affected transactions.

Delayed batched logging does not prove requests are absent from the CDN. The needed control instead targets metric percentiles expose tail latency that an arithmetic mean can mask; it succeeds when the p99 graph exposes the spike and allows correlation with affected transactions.

CDN access logs can distinguish edge-visible request patterns from only origin server events. In this situation, large outliers may have little effect on the mean but violate strict tail-latency service goals. The proposed change does not ensure the p99 graph exposes the spike and allows correlation with affected transactions.

An attachment can have a different associated routing view from where its CIDR propagates. The reported evidence instead concerns cloud WAN attachment policy mapping determines segment membership and allowed routing relationships: connectivity is driven by policy evaluation, not merely existence of a physical or logical attachment.

An attached TGW does not automatically redirect packets that a VPC subnet table sends elsewhere. The decisive technical distinction is cloud WAN attachment policy mapping determines segment membership and allowed routing relationships; connectivity is driven by policy evaluation, not merely existence of a physical or logical attachment.

Peering creates a potential network path while security policy must separately permit service ports. The decisive technical distinction is cloud WAN attachment policy mapping determines segment membership and allowed routing relationships; connectivity is driven by policy evaluation, not merely existence of a physical or logical attachment.

Availability-zone placement can change recurring traffic charges even within a Region. For the stated conditions, centralization simplifies topology but may cost more for bulk traffic than appropriate local paths. The more specific mechanism is Transit Gateway data-processing charges can materially affect high-volume hub-and-spoke designs.

Keeping outbound traffic in the same AZ can reduce cross-zone forwarding and improve failure isolation. That property alone cannot account for the reported symptom; centralization simplifies topology but may cost more for bulk traffic than appropriate local paths.

Central segment policy can simplify management at scale compared with many unrelated regional route tables. That property alone cannot account for the reported symptom; centralization simplifies topology but may cost more for bulk traffic than appropriate local paths.
