AWS Certified Cloud Practitioner — Question 883

A company deployed an application on an Amazon EC2 instance. The application ran as expected for 6 months in the past week, users have reported latency issues. A system administrator found that the CPU utilization was at 100% during business hours. The company wants a scalable solution to meet demand.
Which AWS service or feature should the company use to handle the load for its application during periods of high demand?

Answer options

• A. Auto Scaling groups
• B. AWS Global Accelerator
• C. Amazon Route 53
• D. An Elastic IP address

Correct answer: A

Explanation

Auto Scaling groups allow the application to automatically scale the number of Amazon EC2 instances up or down based on defined conditions, such as high CPU utilization, to handle increased traffic during peak hours. In contrast, AWS Global Accelerator and Amazon Route 53 are routing and networking services that do not add compute capacity to handle high CPU loads. An Elastic IP address simply provides a static IPv4 address and does not offer any scaling capabilities.
