The answer is to enable EFS performance mode with Max I/O. This configuration directly addresses SAP transport directory EFS performance degradation by scaling the file system horizontally across multiple servers, which dramatically increases throughput and IOPS for high-demand workloads. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how SAP transport operations generate parallel I/O patterns that overwhelm the default General Purpose mode, making Max I/O the correct choice when performance issues arise. A common trap is confusing Max I/O with Provisioned Throughput—while both boost performance, Max I/O is specifically designed for unpredictable, bursty workloads like transport directories, whereas Provisioned Throughput is for consistent throughput needs. Remember the mnemonic: “Transport traffic takes Max I/O—General Purpose is too slow.”
PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 NetWeaver on AWS. The system uses a shared file system for transport files via Amazon EFS. Recently, the transport directory performance has degraded. Which configuration change is most likely to improve the I/O performance for the transport directory?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable EFS performance mode with Max I/O.
The correct answer is A because enabling EFS Max I/O performance mode provides higher throughput and IOPS for workloads with high I/O demands, such as SAP transport directories. Max I/O mode scales horizontally by distributing file data across multiple servers, which improves performance for parallel access patterns common in SAP transport operations.
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.
✓
Enable EFS performance mode with Max I/O.
Why this is correct
Max I/O mode optimizes for high throughput and large file operations.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Migrate the transport directory to an Amazon EBS volume.
Why it's wrong here
EBS is not a shared file system; transport directory must be shared across multiple servers.
✗
Use Amazon S3 with a mount point.
Why it's wrong here
S3 is not a POSIX-compliant file system suitable for SAP transports.
✗
Use EFS with Bursting Throughput mode.
Why it's wrong here
Bursting mode may not provide sustained performance for transport operations.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume Bursting Throughput mode (Option D) is sufficient for all EFS workloads, but they overlook that SAP transport directories require sustained high I/O that can exhaust burst credits, making Max I/O mode the better choice for consistent performance.
Detailed technical explanation
How to think about this question
EFS Max I/O mode uses a distributed data plane that spreads file metadata and data across multiple servers, enabling higher aggregate throughput and IOPS compared to General Purpose mode. In SAP NetWeaver, the transport directory (typically /usr/sap/trans) is accessed by multiple application servers for importing and exporting transport requests, creating a workload that benefits from parallel I/O. Under the hood, Max I/O mode sacrifices strong consistency for higher performance, which is acceptable for transport files that are not frequently modified concurrently.

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

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.
