A company uses an Application Load Balancer (ALB) to provide access to a multi-tenant web application for 25 customers.

The company creates a unique hostname for each customer to use to access the application. Hostnames use the format customer-name.example.com.

Each customer has a dedicated group of Amazon EC2 instances that run their own version of the web application. When a customer visits customer-name.example.com, the ALB should route the request to the correct group of EC2 instances. The company requires a highly available solution that is easy to maintain. Which solution meets these requirements at the LOWEST cost?

A.
Create one ALB for all customers. Create a listener rule that includes an HTTP header condition to match the URL. Add aforward action to route the request to the customer target group. Use Amazon Route 53 to create an alias recordfor eachcustomer-name.example.com hostname that points to the ALB.
