Topic 1 Question 34
A company is deploying an application. The application is implemented in a series of containers in an Amazon Elastic Container Service (Amazon ECS) cluster. The company will use the Fargate launch type for its tasks. The containers will run workloads that require connectivity initiated over an SSL connection. Traffic must be able to flow to the application from other AWS accounts over private connectivity. The application must scale in a manageable way as more consumers use the application. Which solution will meet these requirements?
- Choose a Gateway Load Balancer (GLB) as the type of load balancer for the ECS service. Create a lifecycle hook to add new tasks to the target group from Amazon ECS as required to handle scaling. Specify the GLB in the service definition. Create a VPC peer for external AWS accounts. Update the route tables so that the AWS accounts can reach the GLB.
- Choose an Application Load Balancer (ALB) as the type of load balancer for the ECS service. Create path-based routing rules to allow the application to target the containers that are registered in the target group. Specify the ALB in the service definition. Create a VPC endpoint service for the ALB Share the VPC endpoint service with other AWS accounts.

- Choose a Network Load Balancer (NLB) as the type of load balancer for the ECS service. Specify the NLB in the service definition. Create a VPC endpoint service for the NLB. Share the VPC endpoint service with other AWS accounts.

- Path based routing is not required here. Requirement is "Traffic must be able to flow to the application from other AWS accounts over private connectivity. " - which is a case for PrivateLink. It is option D)

  Correct answer is: D B - You cannot create a service endpoint for an ALB Endpoint services require either a Network Load Balancer or a Gateway Load Balancer. The load balancer receives requests from service consumers and routes them to your service. https://docs.aws.amazon.com/vpc/latest/privatelink/create-endpoint-service.html You can have the ALB behind the NLB but not directly as a service endpoint

  No reason to use ALB, SSL != HTTPS, while SSL does not strictly require HTTP, it is typically used in conjunction with HTTP to create HTTPS but it isn't required.
