Exam AWS Certified SysOps Administrator - Associate topic 1 question 92 discussion

Exam question from Amazon's AWS Certified SysOps Administrator - Associate
Question #: 92
Topic #: 1
[All AWS Certified SysOps Administrator - Associate Questions]

A company runs a stateless application that is hosted on an Amazon EC2 instance. Users are reporting performance issues. A SysOps administrator reviews the
Amazon CloudWatch metrics for the application and notices that the instance's CPU utilization frequently reaches 90% during business hours.
What is the MOST operationally efficient solution that will improve the application's responsiveness?

  • A. Configure CloudWatch logging on the EC2 instance. Configure a CloudWatch alarm for CPU utilization to alert the SysOps administrator when CPU utilization goes above 90%.
  • B. Configure an AWS Client VPN connection to allow the application users to connect directly to the EC2 instance private IP address to reduce latency.
  • C. Create an Auto Scaling group, and assign it to an Application Load Balancer. Configure a target tracking scaling policy that is based on the average CPU utilization of the Auto Scaling group.
  • D. Create a CloudWatch alarm that activates when the EC2 instance's CPU utilization goes above 80%. Configure the alarm to invoke an AWS Lambda function that vertically scales the instance.
