- A
Increase the volume size of the EBS volumes to increase the baseline IOPS.
Increasing volume size directly increases the baseline IOPS for gp3 volumes or allows higher provisioned IOPS for io2 volumes, resolving the IOPS limit issue.
- B
Switch from Provisioned IOPS SSD (io2) to General Purpose SSD (gp3) volumes.
Why wrong: Switching to gp3 may not provide sufficient IOPS for the workload if the burst credits are exhausted; gp3 baseline IOPS can be increased but requires a larger volume size.
- C
Enable EBS optimization on the EC2 instances.
Why wrong: EBS optimization is already enabled for current generation instances; enabling it does not increase the IOPS limits of the EBS volumes.
- D
Reduce the number of concurrent connections to the SAP HANA database.
Why wrong: Reducing concurrent connections does not address the IOPS limit of the EBS volumes; the issue is with the storage performance, not the database connections.
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company is running an SAP application on an SAP HANA database in a multi-AZ deployment on AWS. The operations team notices that the system is experiencing high latency during peak hours. Upon investigation, they find that the EBS volumes attached to the HANA instances are frequently exceeding the provisioned IOPS limit. Which of the following is the MOST effective action to resolve this issue?
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
Increase the volume size of the EBS volumes to increase the baseline IOPS.
Option B is correct because increasing the volume size also increases the baseline IOPS for gp3 volumes or allows higher provisioned IOPS for io2 volumes, directly addressing the IOPS limit. Option A is wrong because switching to General Purpose SSD (gp3) can provide higher IOPS at lower cost but does not guarantee the needed IOPS if the burst credits are exhausted. Option C is wrong because reducing the number of concurrent connections does not address the IOPS limit of the EBS volumes. Option D is wrong because enabling EBS optimization is already enabled for current generation instances and does not increase IOPS limits.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Increase the volume size of the EBS volumes to increase the baseline IOPS.
Why this is correct
Increasing volume size directly increases the baseline IOPS for gp3 volumes or allows higher provisioned IOPS for io2 volumes, resolving the IOPS limit issue.

- ✗
Switch from Provisioned IOPS SSD (io2) to General Purpose SSD (gp3) volumes.
Why it's wrong here
Switching to gp3 may not provide sufficient IOPS for the workload if the burst credits are exhausted; gp3 baseline IOPS can be increased but requires a larger volume size.
- ✗
Enable EBS optimization on the EC2 instances.
Why it's wrong here
EBS optimization is already enabled for current generation instances; enabling it does not increase the IOPS limits of the EBS volumes.
- ✗
Reduce the number of concurrent connections to the SAP HANA database.
Why it's wrong here
Reducing concurrent connections does not address the IOPS limit of the EBS volumes; the issue is with the storage performance, not the database connections.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
