When Amazon Route 53 determines an endpoint is unhealthy based on a failure threshold (e.g., via health checks), it terminates the connection attempt to that endpoint and routes traffic to a healthy alternative, if available. This behavior ensures high availability using routing policies like failover or latency-based routing. The WGU Cloud Deployment and Operations Study Guide (Section 3.1, Route 53 Health Checks) states, "Route 53 stops routing traffic to an unhealthy endpoint by terminating connection attempts once the health check failure threshold is exceeded, redirecting to a healthy resource." Options A, C, and D are not direct actions taken by Route 53 in this scenario.

The Reachability Analyzer in AWS VPC should be used to troubleshoot connectivity issues from on-premises computers to EC2 instances, especially when a network security group (NSG) is suspected. It analyzes the network path and identifies blocked traffic due to NSG rules or route tables. The WGU Cloud Deployment and Operations Study Guide (Section 3.2, VPC Troubleshooting) states, "Reachability Analyzer helps diagnose connectivity issues by simulating traffic paths, identifying if an NSG rule (e.g., blocked port) or route table is causing the problem from on-premises to EC2 public IPs." Flow Logs provide data but not analysis, PrivateLink is for private connections, and Traffic Mirroring is for monitoring.

AWS Client VPN is used to provide remote workers with secure access to AWS resources by establishing a VPN connection to the VPC, ensuring encrypted access to private networks. The WGU Cloud Deployment and Operations Study Guide (Section 3.2, Client VPN) states, "Client VPN enables secure remote access to AWS resources within a VPC, using mutual authentication and encryption to protect data for remote workers." Transit Gateway manages inter-VPC routing, Network Firewall filters traffic, and NAT instances handle outbound internet access, none of which are designed for remote worker access.
