Content Domain 3: Cloud Technology and Services

A company wants to rightsize its Amazon EC2 instances.

Which configuration change will meet this requirement with the LEAST operational overhead?

  • A Add EC2 instances in another Availability Zone.
  • B Change the size and type of the EC2 instances based on utilization.
  • C Convert the payment method from On-Demand to Savings Plans.
  • D Reprovision the EC2 instances with a larger instance type.
Explanation

Rightsizing means matching EC2 instance size and type to actual utilization patterns, which can be done directly through instance modification without re-architecting anything. Adding instances in another AZ addresses availability, not sizing; switching to Savings Plans changes the pricing model but not the instance configuration; and simply moving to a larger type without utilization data is the opposite of rightsizing.
