  But why is port 443 necessary?

• 2

  Port 443 is the TCP port for HTTPS which a secured or encrypted version of HTTP. To enable the ALB handle HTTPS traffic having a listener on port 443 is necessary.

• Chose D1

  The correct answer is D. Add an IPv6 CIDR block to the VPC and subnets for the ALB. Create a listener on port 443. and specify the dualstack IP address type on the ALB. Create a target group, and add the EC2 instances as targets. Associate the target group with the ALB.
