Topic 1 Question 171
A company has a memory-intensive application that runs on a fleet of Amazon EC2 instances behind an Elastic Load Balancer (ELB). The instances run in an Auto Scaling group. A SysOps administrator must ensure that the application can scale based on the number of users that connect to the application.
Which solution will meet these requirements?
Create a scaling policy that will scale the application based on the ActiveConnectionCount Amazon CloudWatch metric that is generated from the ELB.
Create a scaling policy that will scale the application based on the mem_used Amazon CloudWatch metric that is generated from the ELB.
Create a scheduled scaling policy to increase the number of EC2 instances in the Auto Scaling group to support additional connections.
Create and deploy a script on the ELB to expose the number of connected users as a custom Amazon CloudWatch metric. Create a scaling policy that uses the metric.
