[All AWS Certified SysOps Administrator - Associate Questions]

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?

  • A. Create a scaling policy that will scale the application based on the ActiveConnectionCount Amazon CloudWatch metric that is generated from the ELB.
  • B. Create a scaling policy that will scale the application based on the mem_used Amazon CloudWatch metric that is generated from the ELB.
  • C. Create a scheduled scaling policy to increase the number of EC2 instances in the Auto Scaling group to support additional connections.
  • D. 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.

Selected Answer: A
Option A is the correct choice: A. Create a scaling policy that will scale the application based on the ActiveConnectionCount CloudWatch metric: The ActiveConnectionCount metric is a measure of the current number of open connections to the ELB. Scaling based on this metric allows the Auto Scaling group to adjust the number of instances based on the demand reflected in the number of active connections.

the key is to publish a CloudWatch metric that tracks active connections, and configure Auto Scaling scaling policies based on that metric to dynamically scale the EC2 fleet behind the ELB as the load changes. Ans: A
