Question

A company's existing AWS environment contains public application servers that run on Amazon EC2 instances. The application servers run in a VPC subnet. Each server is associated with an Elastic IP address. The company has a new requirement for firewall inspection of all traffic from the internet before the traffic reaches any EC2 instances. A security engineer has deployed and configured a Gateway Load Balancer (GLB) in a standalone VPC with a fleet of third-party firewalls. How should a network engineer update the environment to ensure that the traffic travels across the fleet of firewalls?

Options

  • ADeploy a transit gateway. Attach a GLB endpoint to the transit gateway. Attach the application
  • BUpdate the application subnet route table to have a default route to the GLOn the standalone
  • CProvision a GLB endpoint in the application VPC in a new subnet. Create a gateway route table
  • DInstruct the security engineer to move the GLB into the application VPC. Create a gateway route
