  • ○

    By definition, HTTP is a connection orientated protocol and therefore utilises TCP

  • ○

    By definition, HTTP is a connection-less oriented protocol and therefore utilises UDP

  • ○

Question 15

A space exploration company owns a series of telescopes that capture a large number of images and data of the night sky. The images and data are processed on an application hosted on AWS Fargate in a target group assigned to an Application Load Balancer (ALB). The application is made available through the address https://space.example.com.

Scientists require another custom-built application hosted on several Amazon EC2 instances within an Auto Scaling group. This application will be made available from the address https:// space.example.com/meteor. The company needs a solution that can automatically scale from a small number of requests overnight to a large number of requests for a future meteor shower.

What is the MOST operationally efficient solution that meets these requirements?

Select an option, then click Submit answer.

  • ○

    Update the existing target group with the new EC2 instances. Update the application’s ALB by adding a listener rule that redirects /meteor to the newly added EC2 instances.
  • ○

    Create a new target group. Configure the Auto Scaling group of the EC2 instances to use the target group. Update the ALB by adding a listener rule that redirects /meteor to the new target group.
  • ○

    Create a Network Load Balancer (NLB). Configure the NLB to listen on two ports. Configure a target group for one port to deliver all IP traffic to the Auto Scaling group to process the custom images. Configure a target group for the second port to deliver all IP traffic to Fargate. Use path-based routing in the ALB to route traffic for the URL prefix /meteor to the first target group. Route all other paths to the second target group.
  • ○

    Place the ALB behind an Amazon CloudFront distribution. Create a Lambda@Edge function that parses the request URI and adds the path-pattern header with the IP addresses of the EC2 instances to any request for /meteor. Add a listener rule to the ALB that looks for the HTTP header and uses the IP addresses of the EC2 instances to forward the traffic.
