This PAS-C01 practice question tests your understanding of migration. 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 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?

A
Amazon EFS file system
Provides shared file system for multiple instances.
B
Instance Store
Why wrong: Ephemeral storage, not shared.
C
Additional Amazon EBS volume
Why wrong: EBS volumes cannot be attached to multiple instances.
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 mounted across multiple EC2 instances, making it suitable for the SAP transport directory. Option C (Additional EBS volume) is block storage that can only be attached to a single instance, not shared. Option D (Amazon S3 bucket) is object storage, not a file system. Option B (Instance Store) is ephemeral and not shared.
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.
