AWS Certified SysOps Administrator – Associate (legacy) — Question 166

A user has provisioned 2000 IOPS to the EBS volume. The application hosted on that EBS is experiencing less IOPS than provisioned. Which of the below mentioned options does not affect the IOPS of the volume?

Answer options

• A. The application does not have enough IO for the volume
• B. The instance is EBS optimized
• C. The EC2 instance has 10 Gigabit Network connectivity
• D. The volume size is too large

Correct answer: D

Explanation

The correct answer is D because the IOPS provisioned to an EBS volume is independent of its size, provided it meets the minimum size requirements. Options A, B, and C can all impact the IOPS performance; for instance, if the application does not generate enough IO, or if the instance is not properly optimized or has insufficient network capacity, IOPS performance will suffer.
