The correct answer is to enable Max I/O throughput mode on the EFS file system. This choice directly addresses the root cause: the BurstCreditBalance is near zero because the General Purpose mode’s burst model relies on accumulated credits, which are exhausted under sustained high demand from large SAP BusinessObjects reports. By switching to Max I/O, the file system gains a higher throughput baseline that scales with the 500 GB size, eliminating the dependency on burst credits and providing more consistent performance for the shared repository and output files. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of EFS throughput mode tuning for SAP BOBJ workloads, where the common trap is to assume increasing storage size or provisioning throughput is required first. Remember: when burst credits are depleted, Max I/O is the simplest operational fix for throughput-bound, large-file workloads. A helpful memory tip is “Max I/O for Max Throughput”—if your credits are zero, go Max I/O.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 runs SAP BusinessObjects on AWS using multiple EC2 instances. The system uses a shared file system (EFS) for the repository and output files. Recently, users have reported that generating large reports takes much longer than usual. The SAP administrator checks the EFS metrics in CloudWatch and sees that the BurstCreditBalance is consistently near zero. The EFS file system is in General Purpose mode with default throughput settings. The current size of the file system is 500 GB. What should the administrator do to improve performance?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Max I/O throughput mode on the EFS file system.
Option B is correct because enabling Max I/O throughput mode increases the throughput baseline for larger file systems, providing more consistent performance. Option A is wrong because increasing EFS size does not directly improve burst credits; the burst model depends on size. Option C is wrong because using Provisioned Throughput would incur costs but may be appropriate; however, Max I/O is a better first step for a system that has exhausted burst credits. Option D is wrong because transitioning to EFS One Zone does not improve throughput performance.
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.
✗
Migrate the EFS file system to EFS One Zone for better performance.
Why it's wrong here
One Zone does not improve throughput.
✓
Enable Max I/O throughput mode on the EFS file system.
Why this is correct
Max I/O provides higher throughput at scale.
Related concept
Read the scenario before looking for a memorised answer.
✗
Switch to Provisioned Throughput mode and set a higher value.
Why it's wrong here
Provisioned Throughput is an option but Max I/O is simpler and often sufficient.
✗
Increase the size of the EFS file system by adding more data to it.
Why it's wrong here
Size increase does not directly increase burst credits.

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.
