Inbound endpoint existence does not grant resolution of private zones absent from its resolver view. The needed control instead targets an AAAA DNS record publishes an IPv6 address independently of an IPv4 A record; it succeeds when iPv6 client DNS queries receive supported AAAA responses and can connect successfully.

VPC Resolver may use associated private records while public internet resolvers use the public delegation. The needed control instead targets an AAAA DNS record publishes an IPv6 address independently of an IPv4 A record; it succeeds when iPv6 client DNS queries receive supported AAAA responses and can connect successfully.

Inbound endpoints bring permitted DNS queries into the VPC resolver, unlike outbound endpoints sending them out. The needed control instead targets an AAAA DNS record publishes an IPv6 address independently of an IPv4 A record; it succeeds when iPv6 client DNS queries receive supported AAAA responses and can connect successfully.

Security groups lack explicit deny rules while NACL rule-order processing can enforce a scoped subnet deny. It does not directly achieve the required result: only approved application instances can reach the database while other VPC instances cannot. The constraint is that subnet membership alone is weaker identity than authorized workload security-group membership.

Endpoint private addressing does not automatically enforce least-privilege client access. That adjustment does not address the controlling condition: subnet membership alone is weaker identity than authorized workload security-group membership. Verify only approved application instances can reach the database while other VPC instances cannot.

A broad earlier deny can supersede a later allow despite permissive security groups. The needed control instead targets security-group referencing can grant access to only explicitly authorized application groups; it succeeds when only approved application instances can reach the database while other VPC instances cannot.

Connecting attachments to the same Transit Gateway does not by itself permit every attachment to reach every other. It does not directly achieve the required result: private flows follow the explicit narrower route while other traffic follows the default. The constraint is that a default route to a transit hub need not override longer-prefix routes for internal networks.

A route propagated into one TGW table may be invisible to another attachment using a different table. The needed control instead targets VPC route selection uses the most specific matching destination before broader defaults; it succeeds when private flows follow the explicit narrower route while other traffic follows the default.

Resource ownership and spoke VPC ownership can remain separate while attachments are governed centrally. That adjustment does not address the controlling condition: a default route to a transit hub need not override longer-prefix routes for internal networks. Verify private flows follow the explicit narrower route while other traffic follows the default.

Endpoint private addressing does not automatically enforce least-privilege client access. It does not directly achieve the required result: sSH from the bastion works while random internet clients are blocked. The constraint is that using a workload group as source narrows administrative access compared with internet-wide permission.

Private routing to a service is not an authorization grant to every bucket in that service. It does not directly achieve the required result: sSH from the bastion works while random internet clients are blocked. The constraint is that using a workload group as source narrows administrative access compared with internet-wide permission.

Security groups lack explicit deny rules while NACL rule-order processing can enforce a scoped subnet deny. It does not directly achieve the required result: sSH from the bastion works while random internet clients are blocked. The constraint is that using a workload group as source narrows administrative access compared with internet-wide permission.

Weights control relative DNS record selection rather than counting individual HTTP requests or user sessions. The needed control instead targets Route 53 Resolver inbound endpoints receive external recursive queries for VPC-associated private names; it succeeds when corporate clients obtain the expected private VPC record without exposing the zone publicly.

VPC Resolver may use associated private records while public internet resolvers use the public delegation. In this situation, inbound endpoints bring permitted DNS queries into the VPC resolver, unlike outbound endpoints sending them out. The proposed change does not ensure corporate clients obtain the expected private VPC record without exposing the zone publicly.

Publishing a private hosted zone alone does not expose its records to every VPC in an organization. In this situation, inbound endpoints bring permitted DNS queries into the VPC resolver, unlike outbound endpoints sending them out. The proposed change does not ensure corporate clients obtain the expected private VPC record without exposing the zone publicly.

Automated compliance logic can itself create broad security exposure if the execution role is overprivileged. It does not directly achieve the required result: conflicting CIDR configurations are rejected before stacks attempt VPC creation. The constraint is that infrastructure-as-code tools do not infer cross-environment address plans from arbitrary parameters.

A reusable CDK app can deploy to different accounts unless the target is controlled. In this situation, infrastructure-as-code tools do not infer cross-environment address plans from arbitrary parameters. The proposed change does not ensure conflicting CIDR configurations are rejected before stacks attempt VPC creation.

A deployed template cannot guarantee continued agreement after direct console mutations. The needed control instead targets infrastructure deployment validation should check CIDR plan overlap before creating network resources; it succeeds when conflicting CIDR configurations are rejected before stacks attempt VPC creation.

An IaC deployment does not continuously prevent later manual console mutations. For the stated conditions, continuous configuration assessment complements packet monitoring by measuring deployed control state. The more specific mechanism is AWS Config can evaluate security-group configuration against a required policy rule.

A project policy written in documentation does not automatically create log resources. The decisive technical distinction is AWS Config can evaluate security-group configuration against a required policy rule; continuous configuration assessment complements packet monitoring by measuring deployed control state.

Configuration history provides a time series of supported resource states beyond the current console view. The decisive technical distinction is AWS Config can evaluate security-group configuration against a required policy rule; continuous configuration assessment complements packet monitoring by measuring deployed control state.

Creating a rule on a shared outbound endpoint does not cause every VPC to use it automatically. That property alone cannot account for the reported symptom; publicly visible hosted-zone NS addresses do not expose the private record namespace on the internet.

Inbound and outbound endpoint directions describe where queries enter or leave the VPC DNS service. The reported evidence instead concerns private hosted zone data is resolved through VPC Resolver context, not direct public authoritative nameserver queries: publicly visible hosted-zone NS addresses do not expose the private record namespace on the internet.

An association and rule cannot deliver queries when the endpoint subnet lacks a valid packet path. That property alone cannot account for the reported symptom; publicly visible hosted-zone NS addresses do not expose the private record namespace on the internet.

Full network peering requires nonoverlapping CIDRs, while service endpoints abstract the provider's internal addresses. That adjustment does not address the controlling condition: a routed peer cannot distinguish duplicate destination CIDRs in separate VPCs. Verify the chosen architecture enables only the approved reachability without ambiguous overlapping routes.

PrivateLink service access is narrower than full VPC peering and can work across overlapping address spaces. That adjustment does not address the controlling condition: a routed peer cannot distinguish duplicate destination CIDRs in separate VPCs. Verify the chosen architecture enables only the approved reachability without ambiguous overlapping routes.

Resource ownership and spoke VPC ownership can remain separate while attachments are governed centrally. The needed control instead targets VPC peering does not support overlapping VPC IPv4 CIDR blocks for direct routed peering; it succeeds when the chosen architecture enables only the approved reachability without ambiguous overlapping routes.

Central policy can coordinate multi-region connectivity at a higher level than one regional Transit Gateway route table. The decisive technical distinction is privateLink endpoint services support consumer acceptance and allowed-principal restrictions; publishing an endpoint service does not inherently authorize arbitrary accounts to establish private access.

An intermediary peering link does not forward packets between two separately peered VPCs. That property alone cannot account for the reported symptom; publishing an endpoint service does not inherently authorize arbitrary accounts to establish private access.

A route propagated into one TGW table may be invisible to another attachment using a different table. For the stated conditions, publishing an endpoint service does not inherently authorize arbitrary accounts to establish private access. The more specific mechanism is privateLink endpoint services support consumer acceptance and allowed-principal restrictions.

Endpoint private addressing does not automatically enforce least-privilege client access. For the stated conditions, using a workload group as source narrows administrative access compared with internet-wide permission. The more specific mechanism is source security-group references can restrict management ingress to designated hosts.

Private routing to a service is not an authorization grant to every bucket in that service. The decisive technical distinction is source security-group references can restrict management ingress to designated hosts; using a workload group as source narrows administrative access compared with internet-wide permission.

Security groups lack explicit deny rules while NACL rule-order processing can enforce a scoped subnet deny. The reported evidence instead concerns source security-group references can restrict management ingress to designated hosts: using a workload group as source narrows administrative access compared with internet-wide permission.
