Question #: 138
Topic #: 14

A company uses an Amazon EC2 instance to handle requests for a public web application. The application routes traffic to multiple application pages by using URL paths.

The company begins to experience large surges of traffic at unpredictable times. The traffic surges cause the web application to experience issues and to occasionally become unavailable.

The company needs to make the web application more scalable to handle sudden increases in traffic.

Which solution will meet this requirement?


A.

Create an Amazon Machine Image (AMI) of the web application instance. Use the AMI to create an Auto Scaling group of EC2 instances that has a minimum capacity of two. Create an Application Load Balancer. Set the Auto Scaling group as the target group.


B.

Create a Docker image of the application. Use Amazon Elastic Container Service (Amazon ECS) to create an Auto Scaling ECS cluster. Enable managed scaling. Create a Network Load Balancer. Set the ECS cluster as the target group.


C.

Create an Amazon Machine Image (AMI) of the web application instance. Use the AMI to create two more web application instances in separate Availability Zones. Update the website DNS record to refer to all three instances.


D.

Create an Application Load Balancer (ALB). Set the web application instance as the target. Create an Amazon CloudWatch alarm based on ALB traffic metrics. Configure the alert to activate when traffic spikes.
