AWS Certified Solutions Architect – Professional — Question 204

What is the average queue length recommended by AWS to achieve a lower latency for the 200 PIOPS EBS volume?

Answer options

• A. 5
• B. 1
• C. 2
• D. 4

Correct answer: B

Explanation

AWS recommends an average queue length of 1 for optimal latency with a 200 PIOPS EBS volume. Higher queue lengths, such as 2, 4, or 5, can lead to increased latency as they introduce more requests waiting to be processed, which can overwhelm the IOPS limits of the volume.
