The option belongs to a different failure mechanism: There is no network-level DDoS mitigation design for exposed public IP resources. That situation exhibits: The internet edge is overwhelmed by volumetric traffic despite healthy application code. For the stated case, the remedy is: Configure Azure Private Endpoint for the storage subresource and integrate matching private DNS resolution.

That safeguard manages another risk: Private DNS zone link/forwarding architecture does not cover all consuming networks. Its scenario is: Only VMs in the hub resolve private link records while spoke applications resolve public addresses. The present recurring risk is: Private endpoint connectivity and private DNS configuration are incomplete. The proper ongoing control is: Recheck private DNS zone links and endpoint approvals when adding spokes.

The option belongs to a different failure mechanism: Service endpoints secure source traffic to the service's public endpoint rather than creating a private endpoint. That situation exhibits: The database still exposes a public endpoint when only a VNet service endpoint rule is applied. For the stated case, the remedy is: Configure Azure Private Endpoint for the storage subresource and integrate matching private DNS resolution.

This choice mitigates an alternative scenario, where: Apps lose storage connectivity after the account public endpoint is disabled. The underlying issue there is: Private endpoint connectivity and private DNS configuration are incomplete. Here the root issue is: Service endpoints secure source traffic to the service's public endpoint rather than creating a private endpoint. Choose the corresponding action: Select a supported Private Link/private endpoint design when the requirement is private IP connectivity and public endpoint closure.

The option belongs to a different failure mechanism: Network policies are tied to individual addresses rather than logical application group membership. That situation exhibits: An NSG contains hundreds of brittle manually maintained per-IP server rules. For the stated case, the remedy is: Select a supported Private Link/private endpoint design when the requirement is private IP connectivity and public endpoint closure.

That design instead addresses another observed condition: Only VMs in the hub resolve private link records while spoke applications resolve public addresses. Its technical cause is: Private DNS zone link/forwarding architecture does not cover all consuming networks. The current workload exhibits: The database still exposes a public endpoint when only a VNet service endpoint rule is applied. Its targeted remedy is: Select a supported Private Link/private endpoint design when the requirement is private IP connectivity and public endpoint closure.

This check validates a different workload: Resolve the blob FQDN to a private IP and access the account from the approved VNet while public access is restricted. Its associated design is: Configure Azure Private Endpoint for the storage subresource and integrate matching private DNS resolution. The required acceptance test here is: Validate SQL server private name resolution and connectivity from an approved subnet with public network access disabled.

The alternative test targets: Use Azure Private DNS zones with proper VNet links and Azure DNS Private Resolver or supported forwarders. The scenario's actual proposed remedy is: Select a supported Private Link/private endpoint design when the requirement is private IP connectivity and public endpoint closure. Verify that one by: Validate SQL server private name resolution and connectivity from an approved subnet with public network access disabled.

This check validates a different workload: Move a test VM NIC into the database ASG and verify corresponding NSG flow enforcement. Its associated design is: Use Application Security Groups in compatible NSG rules for dynamically grouped VM NICs where supported. The required acceptance test here is: Validate SQL server private name resolution and connectivity from an approved subnet with public network access disabled.

The proposed diagnosis fits another scenario: Private endpoint connectivity and private DNS configuration are incomplete. It would typically be reflected by: Apps lose storage connectivity after the account public endpoint is disabled. The current evidence instead supports: Service endpoints secure source traffic to the service's public endpoint rather than creating a private endpoint.

The alternative weakness is: Private DNS zone link/forwarding architecture does not cover all consuming networks. Its associated failure is: Only VMs in the hub resolve private link records while spoke applications resolve public addresses. Neither explains the present observation: The database still exposes a public endpoint when only a VNet service endpoint rule is applied. The direct cause here is: Service endpoints secure source traffic to the service's public endpoint rather than creating a private endpoint.

This cause would explain a different symptom: An NSG contains hundreds of brittle manually maintained per-IP server rules. The mechanism for that event is: Network policies are tied to individual addresses rather than logical application group membership. Here the stated symptom is: The database still exposes a public endpoint when only a VNet service endpoint rule is applied. Its cause is: Service endpoints secure source traffic to the service's public endpoint rather than creating a private endpoint.

That safeguard manages another risk: Network policies are tied to individual addresses rather than logical application group membership. Its scenario is: An NSG contains hundreds of brittle manually maintained per-IP server rules. The present recurring risk is: Service endpoints secure source traffic to the service's public endpoint rather than creating a private endpoint. The proper ongoing control is: Document when Private Link versus service endpoint is appropriate for each PaaS resource.

This is a reasonable safeguard for a different fault: Only VMs in the hub resolve private link records while spoke applications resolve public addresses. That different mechanism is: Private DNS zone link/forwarding architecture does not cover all consuming networks. The original incident here instead arises from: Service endpoints secure source traffic to the service's public endpoint rather than creating a private endpoint. The directly relevant safeguard is: Document when Private Link versus service endpoint is appropriate for each PaaS resource.

Here the root issue is: Private DNS zone link/forwarding architecture does not cover all consuming networks. Choose the corresponding action: Use Azure Private DNS zones with proper VNet links and Azure DNS Private Resolver or supported forwarders.

The option belongs to a different failure mechanism: VNet peering does not create arbitrary transitive route propagation by itself. That situation exhibits: Spoke A cannot reach Spoke B despite both VNets having healthy peering to Hub. For the stated case, the remedy is: Use Azure Private DNS zones with proper VNet links and Azure DNS Private Resolver or supported forwarders.

That design instead addresses another observed condition: The database still exposes a public endpoint when only a VNet service endpoint rule is applied. Its technical cause is: Service endpoints secure source traffic to the service's public endpoint rather than creating a private endpoint. The current workload exhibits: Only VMs in the hub resolve private link records while spoke applications resolve public addresses. Its targeted remedy is: Use Azure Private DNS zones with proper VNet links and Azure DNS Private Resolver or supported forwarders.

That observation pertains to a separate failure: Spoke A cannot reach Spoke B despite both VNets having healthy peering to Hub. Its cause is: VNet peering does not create arbitrary transitive route propagation by itself. It does not confirm the result of this design. The direct proof would be: Resolve a private endpoint FQDN from a spoke and an on-prem client and verify the intended private address.

The option belongs to a different failure mechanism: No global Layer 7 edge routing and acceleration architecture is deployed. That situation exhibits: Users in distant regions have high latency and no automatic cross-region web failover. For the stated case, the remedy is: Use Azure Application Gateway v2 with an appropriate listener, path map, certificate and backend health probes.

That design instead addresses another observed condition: A single-region service address remains in DNS despite the secondary service being healthy. Its technical cause is: No DNS-level endpoint monitoring and failover policy exists. The current workload exhibits: One generic L4 listener cannot route image versus payment URL paths to separate services. Its targeted remedy is: Use Azure Application Gateway v2 with an appropriate listener, path map, certificate and backend health probes.

This choice mitigates an alternative scenario, where: Operations manually update dozens of static route tables after every NVA prefix change. The underlying issue there is: No managed dynamic route exchange is configured for the hub appliances. Here the root issue is: A transport load balancer was selected for HTTP-specific routing requirements. Choose the corresponding action: Use Azure Application Gateway v2 with an appropriate listener, path map, certificate and backend health probes.

This check validates a different workload: Disable one origin and verify users in multiple locations reach a healthy origin through the edge. Its associated design is: Use Azure Front Door with compatible origins and route/health policies for worldwide web clients. The required acceptance test here is: Request two paths and verify they reach the intended pools while unhealthy backends are avoided.

That observation pertains to a separate failure: A single-region service address remains in DNS despite the secondary service being healthy. Its cause is: No DNS-level endpoint monitoring and failover policy exists. It does not confirm the result of this design. The direct proof would be: Request two paths and verify they reach the intended pools while unhealthy backends are avoided.

The alternative test targets: Use Azure Route Server with supported BGP peers and routing topology when compatible with required gateway/NVA features. The scenario's actual proposed remedy is: Use Azure Application Gateway v2 with an appropriate listener, path map, certificate and backend health probes. Verify that one by: Request two paths and verify they reach the intended pools while unhealthy backends are avoided.
