QUESTION: 49 Exam Topic: 1 Exam Pool A

A Security Engineer for a large company is managing a data processing application used by 1,500 subsidiary companies. The parent and subsidiary companies all use IAM. The application uses TCP port 443 and runs on Amazon EC2 behind a Network Load Balancer (NLB). For compliance reasons, the application should only be accessible to the subsidiaries and should not be available on the public internet. To meet the compliance requirements for restricted access, the Engineer has received the public and private CIDR block ranges for each subsidiary

What solution should the Engineer use to implement the appropriate access restrictions for the application?

Create a NACL to allow access on TCP port 443 from the 1;500 subsidiary CIDR block ranges. Associate the NACL to both the NLB and EC2 instances
Create an IAM security group to allow access on TCP port 443 from the 1,500 subsidiary CIDR block ranges. Associate the security group to the NL Create a second security group for EC2 instances with access on TCP port 443 from the NLB security group.
Create an IAM PrivateLink endpoint service in the parent company account attached to the NLB. Create an IAM security group for the instances to allow access on TCP port 443 from the IAM PrivateLink endpoint. Use IAM PrivateLink interface endpoints in the 1,500 subsidiary IAM accounts to connect to the data processing application.
Create an IAM security group to allow access on TCP port 443 from the 1,500 subsidiary CIDR block ranges. Associate the security group with EC2 instances.
