A company operates a public application that utilizes an Application Load Balancer (ALB) with a target group consisting of Amazon EC2 instances. To safeguard the application from web request security vulnerabilities and ensure end-to-end encryption for all traffic, what solution should be implemented?
A
Configure a Network Load Balancer (NLB) that has a target group of the existing EC2 instances. Configure TLS connections to terminate on the EC2 instances that use a public certificate. Configure an AWS WAF web ACL. Associate the web ACL with the NLB.
B
Configure TLS connections to terminate at the ALB that uses a public certificate. Configure AWS Certificate Manager (ACM) certificates for the communication between the ALB and the EC2 instances. Configure an AWS WAF web ACL. Associate the web ACL with the ALB.
C
Configure a Network Load Balancer (NLB) that has a target group of the existing EC2 instances. Configure TLS connections to terminate at the EC2 instances by creating a TLS listener. Configure self-signed certificates on the EC2 instances for the communication between the NLB and the EC2 instances. Configure an AWS WAF web ACL. Associate the web ACL with the NLB.
D
Configure a third-party certificate on the EC2 instances for the communication between the ALB and the EC2 instances. Import the third-party certificate into AWS Certificate Manager (ACM). Associate the imported certificate with the ALB. Configure TLS connections to terminate at the ALB. Configure an AWS WAF web ACL. Associate the web ACL with the ALB.
