gp2 Volume IOPS Calculation — 3 IOPS per GiB | AWS SAP on AWS Specialty Explained

This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

An SAP administrator runs the command shown in the exhibit. The volume is attached to an EC2 instance. The administrator plans to increase the volume size to 1000 GiB. After resizing, the volume type remains gp2. What is the expected baseline IOPS for the resized volume?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

3000 IOPS

Option C is correct because gp2 volumes have a baseline IOPS of 3 IOPS per GiB, up to a maximum of 16,000 IOPS. For a 1000 GiB gp2 volume, the calculation is 1000 × 3 = 3000 IOPS, which is below the 16,000 IOPS cap, so the expected baseline IOPS is exactly 3000.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • 4500 IOPS

    Why it's wrong here

    Incorrect calculation.

  • 16,000 IOPS

    Why it's wrong here

    That is the maximum burst IOPS, not baseline.

  • 3000 IOPS

    Why this is correct

    Baseline IOPS = 3 * 1000 = 3000.

    Related concept

    Read the scenario before looking for a memorised answer.

  • 1500 IOPS

    Why it's wrong here

    That was the previous IOPS for 500 GiB.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse the gp2 baseline IOPS calculation (3 IOPS/GiB) with the gp3 baseline (3000 IOPS fixed for any size) or mistakenly apply the 16,000 IOPS cap as a default value for all gp2 volumes, rather than recognizing it as a maximum that only applies at larger sizes.

Detailed technical explanation

How to think about this question

The gp2 volume type uses a credit-based burst model where baseline IOPS is calculated at 3 IOPS per GiB, and volumes smaller than 1000 GiB can burst to 3000 IOPS using accumulated I/O credits. For volumes larger than 1000 GiB, the baseline IOPS itself exceeds 3000, so the burst mechanism is no longer needed; the 16,000 IOPS cap is a hard limit on the baseline calculation, not a burst ceiling. In real-world SAP workloads, understanding this distinction is critical because a 1000 GiB gp2 volume provides a consistent 3000 IOPS without relying on burst credits, which is important for predictable performance.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
