- A
Change the volume type to gp3 and adjust the IOPS and throughput settings.
gp3 provides baseline performance without burst credits.
- B
Increase the size of the gp2 volumes to increase the baseline IOPS.
Why wrong: Increasing size increases baseline IOPS but still uses burst credits; gp3 is a better solution.
- C
Move the data to instance store volumes for better performance.
Why wrong: Instance store is ephemeral and not suitable for persistent SAP data.
- D
Change the volume type to io1 and provision high IOPS.
Why wrong: io1 is expensive and overprovisioned; gp3 offers a cost-effective solution.

EBS gp2 Burst Credits Depletion — Upgrade to gp3 for SAP | 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 notices that the SAP application server performance degrades during peak hours. The application servers are running on EC2 instances with gp2 EBS volumes. The administrator suspects the EBS volumes are experiencing burst bucket depletion. Which action should the administrator take to improve performance?
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
✓
Change the volume type to gp3 and adjust the IOPS and throughput settings.
The gp2 volume type uses a credit-based burst model where performance degrades once the burst bucket is depleted, especially under sustained high I/O. Changing to gp3 provides a baseline performance that does not rely on burst credits, and you can independently provision higher IOPS and throughput without increasing storage size, directly addressing the performance degradation during peak hours.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume increasing gp2 volume size (Option B) is the only way to improve baseline IOPS, overlooking that gp3 provides a simpler, more cost-effective solution that directly addresses burst bucket depletion without requiring storage resizing.
Detailed technical explanation
How to think about this question
gp2 volumes accumulate burst credits at a rate of 3 IOPS per GB (up to a maximum of 16,000 IOPS for volumes over 1,000 GB), and once the credit balance is exhausted, throughput drops to the baseline IOPS. gp3 volumes offer a baseline of 3,000 IOPS and 125 MB/s regardless of volume size, with the ability to provision up to 16,000 IOPS and 1,000 MB/s independently, making them ideal for workloads like SAP that experience sustained I/O spikes. In real-world scenarios, SAP application servers often require consistent I/O for database logs and data files, and gp3 eliminates the unpredictable performance cliff associated with burst bucket depletion.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
