Content Domain 3: Cloud Technology and Services

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?

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

Amazon EC2 Auto Scaling groups automatically launch or terminate instances based on demand or defined scaling policies, keeping the number of running instances aligned with current load. Dedicated Hosts and Reserved Instances are billing and hardware-allocation options, and placement groups only control how instances are physically arranged, none of which adjust instance count automatically.
