A Web Application Runs on Amazon EC2 Instances with Public

question 910

Multiple Choice

A web application runs on Amazon EC2 instances with public IPs assigned behind an Application Load Balancer. The instances run in an Auto Scaling group across multiple Availability Zones. The application stores data in an Amazon RDS Multi-AZ DB instance. The Application Load Balancer, EC2 instances, and RDS DB instance all run in separate sets of subnets. The EC2 instances can communicate with the DB instance, but cannot connect with external services. What is the MOST likely solution?

• A) Assign a public IP address to the database server and restart the database engine.
• B) Create and attach an Internet gateway to the VPC. Create a route table for the EC2 instance's subnets that sends Internet traffic to the gateway.
• C) Create and attach a virtual private gateway to the VPC. Create a route table for the EC2 instances' subnets that sends Internet traffic to the gateway.
• D) Create a VPC peering connection to a VPC that has an Internet gateway attached. Create a route table for the EC2 instances' subnets that sends Internet traffic to the peered VPC.
