Endpoint private addressing does not automatically enforce least-privilege client access. For the stated conditions, removing ingress permissions alone does not stop instances initiating outbound connections. The more specific mechanism is security group egress and ingress permissions are configured independently for new flows.

A successful inbound rule does not automatically authorize reply packets under a stateless ACL. The reported evidence instead concerns security group egress and ingress permissions are configured independently for new flows: removing ingress permissions alone does not stop instances initiating outbound connections.

A broad earlier deny can supersede a later allow despite permissive security groups. The reported evidence instead concerns security group egress and ingress permissions are configured independently for new flows: removing ingress permissions alone does not stop instances initiating outbound connections.

Owning the Transit Gateway does not automatically grant authority to attach another account's Direct Connect gateway. It does not directly achieve the required result: the corporate router learns the full intended VPC CIDR after correcting the filter. The constraint is that vGW allowed-prefix filters cannot force unsupported more-specific VPC routes to appear in BGP.

The virtual interface type determines whether connectivity targets private VPC addresses or public AWS endpoints. It does not directly achieve the required result: the corporate router learns the full intended VPC CIDR after correcting the filter. The constraint is that vGW allowed-prefix filters cannot force unsupported more-specific VPC routes to appear in BGP.

Dedicated connectivity avoids relying exclusively on public internet paths but does not inherently encrypt payloads. The needed control instead targets for virtual private gateway associations, allowed prefixes filter VPC CIDRs and cannot advertise an unmatched narrower CIDR; it succeeds when the corporate router learns the full intended VPC CIDR after correcting the filter.

A healthy NLB can still direct clients to overloaded targets when the target fleet is undersized. The needed control instead targets subnet available IP address capacity constrains the launch of network interfaces for new instances; it succeeds when the ASG launches required capacity in subnets with adequate assignable addresses.

Keeping outbound traffic in the same AZ can reduce cross-zone forwarding and improve failure isolation. In this situation, EC2 scaling cannot allocate ENIs when the chosen subnets have no free addresses. The proposed change does not ensure the ASG launches required capacity in subnets with adequate assignable addresses.

Target discovery must follow workload life cycle to avoid forwarding to stopped or obsolete tasks. That adjustment does not address the controlling condition: EC2 scaling cannot allocate ENIs when the chosen subnets have no free addresses. Verify the ASG launches required capacity in subnets with adequate assignable addresses.

A private S3 origin prevents viewers bypassing edge controls through an unrestricted bucket endpoint. It does not directly achieve the required result: missing image requests show the approved fallback with expected status and cache behavior. The constraint is that origin error statuses can be mapped to viewer-facing responses without modifying the origin application.

Changing an origin file does not automatically replace copies already cached at edge locations. It does not directly achieve the required result: missing image requests show the approved fallback with expected status and cache behavior. The constraint is that origin error statuses can be mapped to viewer-facing responses without modifying the origin application.

The front-end static IPs remain stable even when the backend Regional endpoint set changes. It does not directly achieve the required result: missing image requests show the approved fallback with expected status and cache behavior. The constraint is that origin error statuses can be mapped to viewer-facing responses without modifying the origin application.

Instance running state is distinct from the health check HTTP response required by the target group. It does not directly achieve the required result: backend logs show the expected original client IP after the verified configuration. The constraint is that the source identity visible to a target can differ based on transport and load-balancing configuration.

Dynamic container networking requires registration of actual reachable task addresses instead of fixed node identities. In this situation, the source identity visible to a target can differ based on transport and load-balancing configuration. The proposed change does not ensure backend logs show the expected original client IP after the verified configuration.

Layer-seven request properties are available to an ALB but not to a pure layer-four listener. In this situation, the source identity visible to a target can differ based on transport and load-balancing configuration. The proposed change does not ensure backend logs show the expected original client IP after the verified configuration.

Static copied gateway IDs can drift after replacement, causing invalid routes. It does not directly achieve the required result: each test VPC receives the correct validated tags and noncompliant cases are flagged. The constraint is that event-driven code can enforce organizational metadata conventions without granting unrestricted administrator access.

One organization's manual copy/paste cannot maintain consistent revisions as account counts grow. The needed control instead targets lambda functions can run event-driven validation logic with scoped IAM permissions; it succeeds when each test VPC receives the correct validated tags and noncompliant cases are flagged.

Event-driven notifications observe resource modifications instead of waiting for scheduled inventory scans. In this situation, event-driven code can enforce organizational metadata conventions without granting unrestricted administrator access. The proposed change does not ensure each test VPC receives the correct validated tags and noncompliant cases are flagged.

A BGP route to a network does not grant permission through intermediate stateful firewalls. The decisive technical distinction is IPsec encapsulation reduces effective MTU, so path MTU discovery and fragmentation policy affect hybrid traffic; oversized packets can be dropped when the effective encrypted path cannot carry their size.

Tunnel health alone does not create a routing advertisement for an omitted customer network. For the stated conditions, oversized packets can be dropped when the effective encrypted path cannot carry their size. The more specific mechanism is IPsec encapsulation reduces effective MTU, so path MTU discovery and fragmentation policy affect hybrid traffic.

An active VIF and BGP session do not automatically override VPC subnet forwarding decisions. The decisive technical distinction is IPsec encapsulation reduces effective MTU, so path MTU discovery and fragmentation policy affect hybrid traffic; oversized packets can be dropped when the effective encrypted path cannot carry their size.

A signed child zone alone does not prove authenticity to validators without the parent trust chain. That property alone cannot account for the reported symptom; forwarding alone transports DNS answers and does not guarantee cryptographic integrity validation.

A stale DS pointer can invalidate an otherwise correctly served new signing key. The reported evidence instead concerns resolver DNSSEC validation can detect invalid signed responses when enabled for eligible VPCs: forwarding alone transports DNS answers and does not guarantee cryptographic integrity validation.

A private DNS record invisible to ACM's validation resolvers cannot prove public domain control. The reported evidence instead concerns resolver DNSSEC validation can detect invalid signed responses when enabled for eligible VPCs: forwarding alone transports DNS answers and does not guarantee cryptographic integrity validation.

No BGP propagation exists to fill missing route entries in a static-only configuration. It does not directly achieve the required result: corporate BGP prefixes appear in the table used by the application attachment. The constraint is that a healthy VPN tunnel does not automatically install every required prefix into every TGW routing domain.

Overbroad BGP originations can redirect corporate traffic beyond intended AWS destinations. It does not directly achieve the required result: corporate BGP prefixes appear in the table used by the application attachment. The constraint is that a healthy VPN tunnel does not automatically install every required prefix into every TGW routing domain.

Gateway attachments are route targets; incorrect associations can blackhole return flows despite healthy tunnels. It does not directly achieve the required result: corporate BGP prefixes appear in the table used by the application attachment. The constraint is that a healthy VPN tunnel does not automatically install every required prefix into every TGW routing domain.

A valid network route cannot compensate for missing administrative permission to manage the shared resource. It does not directly achieve the required result: path analysis shows the replacement attachment carrying the intended traffic. The constraint is that a route-table entry is not proof the next-hop attachment remains operational.

A route marked blackhole cannot carry IPv4 outbound traffic regardless of instance state. The needed control instead targets tGW static routes can become unusable when their referenced attachment no longer exists; it succeeds when path analysis shows the replacement attachment carrying the intended traffic.

Peer connection state does not automatically propagate remote VPC CIDR changes. In this situation, a route-table entry is not proof the next-hop attachment remains operational. The proposed change does not ensure path analysis shows the replacement attachment carrying the intended traffic.

Full network peering requires nonoverlapping CIDRs, while service endpoints abstract the provider's internal addresses. The reported evidence instead concerns VPC peering is nontransitive and cannot use one peer as a router to another peer: an intermediary peering link does not forward packets between two separately peered VPCs.

Mesh peering grows rapidly in connection and route-management complexity compared with centralized transit routing. That property alone cannot account for the reported symptom; an intermediary peering link does not forward packets between two separately peered VPCs.

TGW peering does not automatically propagate all local routes between peer gateways. That property alone cannot account for the reported symptom; an intermediary peering link does not forward packets between two separately peered VPCs.
