The new gateway public endpoint establishes both tunnels and the old one is retired might confirm another remediation, for instance when a migration moves a customer gateway to a new public IP address but the Site-to-Site VPN attachment still references the old address. This question instead requires demonstrating that both tunnel BGP peers reach Established and exchange approved prefixes. The alternative would not validate the selected network fix.

Approved public endpoint traffic follows the expected Direct Connect public routing path might confirm another remediation, for instance when a company needs public AWS service API access across a Direct Connect public VIF but has not advertised eligible public prefixes. This question instead requires demonstrating that both tunnel BGP peers reach Established and exchange approved prefixes. The alternative would not validate the selected network fix.

Tunnel counters rise for intended traffic and end-to-end probes succeed might confirm another remediation, for instance when an on-premises firewall permits IPSec negotiation but blocks encapsulated user traffic after tunnel setup. This question instead requires demonstrating that both tunnel BGP peers reach Established and exchange approved prefixes. The alternative would not validate the selected network fix.

Measure path MTU and adjust MSS or tunnel configuration for encapsulation overhead would address a different scenario, such as when a cloud-hosted service is reachable over VPN but larger TLS messages time out despite small pings succeeding.

Configure supported VPC Traffic Mirroring with scoped capture filters to a protected target would address a different scenario, such as when an internal review needs proof that the same TCP conversation was observed at an inspection point during a suspected incident. The present issue requires inspect or enable CloudTrail coverage for supported Resolver API operations because the network path and control point are different; the alternative does not directly meet this requirement.

Enable suitable AWS Config recording and network-related compliance evaluations would address a different scenario, such as when an auditor asks for evidence that prohibited network routes are detected if changed outside IaC. The present issue requires inspect or enable CloudTrail coverage for supported Resolver API operations because the network path and control point are different; the alternative does not directly meet this requirement.

Permitted initiated sessions return successfully without unrelated new inbound access might confirm another remediation, for instance when a network engineer opens all ephemeral ports inbound in a security group believing return packets require explicit permits.

An attempt to use the bypass next hop fails while approved proxy traffic works might confirm another remediation, for instance when a company routes all outbound traffic through a transparent proxy but direct routes to the NAT gateway remain available. This question instead requires demonstrating that necessary destinations remain reachable while disallowed test egress is denied. The alternative would not validate the selected network fix.

Public DNS follows delegation chain name-server records rather than the zone console selected by users explains a different case, for example when a public delegated subdomain has been created in Route 53 but the registrar still delegates only to the old name servers. In the current topology, the deciding factor is that resolver query logs provide query-name and source-related metadata for VPC DNS activity; this choice therefore does not explain the specified remedy.

PrivateLink DNS must map the desired service name to reachable consumer endpoint ENI addresses explains a different case, for example when an internal API is exposed by PrivateLink but consumers resolve its hostname to a public ALB. In the current topology, the deciding factor is that resolver query logs provide query-name and source-related metadata for VPC DNS activity; this choice therefore does not explain the specified remedy.

Weighted records influence proportions of DNS responses, not guaranteed individual HTTP requests explains a different case, for example when a global service migration needs only ten percent of DNS answers to direct to a canary regional endpoint.
