A Direct Connect gateway can connect eligible transit virtual interfaces to TGWs across supported Regions, avoiding a separate VIF per individual VPC; that still would not establish the requested outcome: encrypt eligible physical DX frames.

LAG combines supported same-speed physical connections under one logical construct; individual BGP flow hashing and circuit health still affect realized traffic distribution; the scenario instead needs an action that will encrypt eligible physical DX frames.

A private DX connection supplies dedicated network connectivity but does not inherently guarantee end-to-end payload encryption for all services; overlay encryption must be deliberately deployed when needed; it changes a different aspect of the architecture rather than fulfilling the need to encrypt eligible physical DX frames.

ALB mutual TLS verification can consult configured CRLs in its trust store; relying only on an unchanged CA certificate would continue accepting a nonexpired certificate unless revocation is enforced; the scenario instead needs an action that will serve distinct HTTPS certificates by hostname.

ALB can initiate HTTPS connections to backend targets, protecting the load-balancer-to-target segment; this is distinct from configuring a viewer-side HTTPS listener; those conditions do not produce the required result: serve distinct HTTPS certificates by hostname.

ALB security policies govern the protocols and ciphers accepted by its TLS listener; rotating the certificate alone does not disable old protocol versions; the operational gap would remain because the question requires a way to serve distinct HTTPS certificates by hostname.

ALB mutual authentication can verify client certificates for inbound HTTPS sessions while preserving the ability to apply application-layer listener rules; those conditions do not produce the required result: reject revoked TLS client certificates.

ALB security policies govern the protocols and ciphers accepted by its TLS listener; rotating the certificate alone does not disable old protocol versions; the operational gap would remain because the question requires a way to reject revoked TLS client certificates.

Server Name Indication lets the load balancer choose the appropriate configured certificate for the requested hostname without requiring one public IP per certificate; it is not the action that directly makes the system reject revoked TLS client certificates.

The ALERT action records matching traffic for inspection but does not itself reject the associated TCP session or return an active refusal. It therefore cannot meet a requirement for explicit connection rejection.

PASS permits matching flows through the firewall rather than rejecting or dropping them. This is the opposite of an explicit refusal and does not signal rejection to the initiating client.

DNSSEC validation checks authenticity of DNS data and does not provide packet-level TCP reset behavior for arbitrary firewall flows.

Viewer protocol rules protect the first hop, while the custom-origin protocol policy controls encryption between CloudFront and the ALB; the origin must serve a certificate valid for the requested origin name; the operational gap would remain because the question requires a way to permit CloudFront access to KMS-encrypted S3 objects.

Signed cookies let CloudFront authorize a viewer to access a set of protected files based on policy and signature, appropriate when a session fetches multiple related objects; it is not the action that directly makes the system permit CloudFront access to KMS-encrypted S3 objects.

S3 website endpoints are custom HTTP origins and do not support OAC; the regional REST endpoint can accept CloudFront-signed origin requests while public S3 access remains blocked; that still would not establish the requested outcome: permit CloudFront access to KMS-encrypted S3 objects.

Viewer protocol rules protect the first hop, while the custom-origin protocol policy controls encryption between CloudFront and the ALB; the origin must serve a certificate valid for the requested origin name; that still would not establish the requested outcome: repair invalid TLS identity at a CDN custom origin.

Imported certificates are managed by the owner for renewal and re-import, unlike eligible ACM-issued certificates whose automated renewal conditions may be satisfied; the scenario instead needs an action that will repair invalid TLS identity at a CDN custom origin.

ACM Private CA provides private trust roots for internal certificates, unlike public ACM certificates that require public domain validation and publicly trusted naming; those conditions do not produce the required result: repair invalid TLS identity at a CDN custom origin.

VPC Flow Logs and Network Firewall logging can both be enabled; collecting one does not require disabling the other.

Logging configuration does not change a policy's configured strict versus action order into another rule-evaluation mode.

S3 gateway endpoints change S3 traffic routing and have no general effect on alert generation by stateful firewall default actions.

IKE authentication depends on matching configured credentials and compatible proposals; reachability to the outside addresses does not prove those credentials agree; the scenario instead needs an action that will rotate IPsec authentication credentials safely.

The inside addresses identify separate point-to-point BGP interfaces and must not collide; reusing the same inside tunnel CIDR makes distinct neighbor and forwarding contexts ambiguous; those conditions do not produce the required result: rotate IPsec authentication credentials safely.

IPsec tunnel establishment authenticates the encrypted underlay; dynamic route exchange requires a separate BGP session with the correct neighbors and ASN over the tunnel interfaces; it changes a different aspect of the architecture rather than fulfilling the need to rotate IPsec authentication credentials safely.

ALB mutual authentication can verify client certificates for inbound HTTPS sessions while preserving the ability to apply application-layer listener rules; those conditions do not produce the required result: encrypt ALB-to-EC2 traffic.

Slow start gradually increases traffic sent to a newly healthy target during its configured warm-up interval, limiting sudden load as the replacement becomes ready; the operational gap would remain because the question requires a way to encrypt ALB-to-EC2 traffic.

The deregistration delay sets how long a deregistering target can continue draining existing requests before being fully removed from service; it is not the action that directly makes the system encrypt ALB-to-EC2 traffic.

ALB mutual TLS verification can consult configured CRLs in its trust store; relying only on an unchanged CA certificate would continue accepting a nonexpired certificate unless revocation is enforced; it changes a different aspect of the architecture rather than fulfilling the need to enforce a modern minimum TLS version.

ALB mutual authentication can verify client certificates for inbound HTTPS sessions while preserving the ability to apply application-layer listener rules; it is not the action that directly makes the system enforce a modern minimum TLS version.

Server Name Indication lets the load balancer choose the appropriate configured certificate for the requested hostname without requiring one public IP per certificate; that still would not establish the requested outcome: enforce a modern minimum TLS version.

CloudFront validates HTTPS connections to custom origins, so an expired or mismatched certificate can prevent origin negotiation and lead to a 502 even when viewer-side TLS works; the operational gap would remain because the question requires a way to manage expiry of imported load balancer certificates.

CloudFront custom viewer certificates managed by ACM are sourced from us-east-1 even if the distribution's origins and application workloads run elsewhere; it is not the action that directly makes the system manage expiry of imported load balancer certificates.

ACM Private CA provides private trust roots for internal certificates, unlike public ACM certificates that require public domain validation and publicly trusted naming; that still would not establish the requested outcome: manage expiry of imported load balancer certificates.
