AWS Certified SysOps Administrator – Associate (legacy) — Question 363

A user is trying to create an EBS volume with the highest PIOPS supported by EBS. What is the minimum size of EBS required to have the maximum IOPS?

Answer options

• A. 124
• B. 150
• C. 134
• D. 128

Correct answer: C

Explanation

To achieve the maximum Provisioned IOPS (PIOPS) on an EBS volume, AWS enforces a specific ratio of IOPS to volume size (GiB). Based on the maximum IOPS-to-GiB provisioning limits for these storage types, a minimum volume size of 134 GiB is required to unlock the absolute maximum supported IOPS. Smaller sizes will be capped at a lower maximum IOPS due to these strict scaling ratios.
