AWS Certified Cloud Practitioner (CLF-C02) — Question 703

A company wants a solution that will automatically adjust the number of Amazon EC2 instances that are being used based on the current load.

Which AWS offering will meet these requirements?

Answer options

• A. Dedicated Hosts
• B. Placement groups
• C. Auto Scaling groups
• D. Reserved Instances

Correct answer: C

Amazon EC2 Auto Scaling groups automatically adjust the number of EC2 instances to maintain performance and handle load spikes or drops. Dedicated Hosts and Reserved Instances are tenancy and purchasing options, respectively, while placement groups control the physical layout of instances but do not scale them.
