AWS Certified Cloud Practitioner — Question 522

A company needs to reserve a certain amount of Amazon EC2 compute resources in a specific Availability Zone within an AWS Region.

Which purchasing option should the company use to meet this requirement?

Answer options

• A. EC2 Instance Savings Plans
• B. Compute Savings Plans
• C. Regional Reserved Instances
• D. Zonal Reserved Instances

Correct answer: D

Explanation

Zonal Reserved Instances provide a capacity reservation specifically in the chosen Availability Zone, guaranteeing that the EC2 resources will be available when needed. Regional Reserved Instances and Savings Plans (both Compute and EC2 Instance Savings Plans) provide pricing discounts but do not offer a capacity reservation in a specific Availability Zone.
