The answer is an Amazon EFS file system. This is the correct choice because EFS provides a fully managed, scalable Network File System (NFS) that can be mounted concurrently by multiple EC2 instances, which is essential for the SAP transport directory shared across the ASCS instance and other SAP nodes. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this tests your understanding that SAP’s transport directory requires a POSIX-compliant, multi-attach shared file system—something block storage like EBS volumes cannot offer, as they can only be attached to a single instance at a time. A common trap is selecting an additional EBS volume, but remember that EBS is single-instance block storage, not a shared file system. For a quick memory tip: think “EFS for shared SAP files” and recall that the “S” in EFS stands for “shared” to distinguish it from EBS’s single-attach limitation.
PAS-C01 Migration Practice Question
This PAS-C01 practice question tests your understanding of migration. 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 migrating SAP applications to AWS and uses the CloudFormation template snippet shown in the exhibit. The SAP ASCS instance requires a shared file system for the transport directory. However, the template does not create any shared storage. Which AWS resource should be added to the template to provide a shared file system?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon EFS file system
Amazon EFS provides a scalable shared file system that can be used for SAP transport directory. Option A (Additional EBS volume) is block storage that cannot be shared across instances. Option B (Amazon S3 bucket) is object storage. Option C (Instance Store) is ephemeral.
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
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 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.
