Amazon Web Services SAA-C03 Question Answer

A company hosts a web application in a VPC on AWS. A public Application Load Balancer (ALB) forwards connections from the internet to an Auto Scaling group of Amazon EC2 instances. The Auto Scaling group runs in private subnets across four Availability Zones.

The company stores data in an Amazon S3 bucket in the same Region. The EC2 instances use NAT gateways in each Availability Zone for outbound internet connectivity.

The company wants to optimize costs for its AWS architecture.

Which solution will meet this requirement?

Reconfigure the Auto Scaling group and the ALB to use two Availability Zones instead of four. Do not change the desired count or scaling metrics for the Auto Scaling group to maintain application availability.

Create a new, smaller VPC that still has sufficient IP address availability to run the application. Redeploy the application stack in the new VPC. Delete the existing VPC and its resources.

Deploy an S3 gateway endpoint to the VPC. Configure the EC2 instances to access the S3 bucket through the S3 gateway endpoint.

Deploy an S3 interface endpoint to the VPC. Configure the EC2 instances to access the S3 bucket through the S3 interface endpoint.
