SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 a legacy on-premises application to AWS. The application requires a shared file system that can be mounted by multiple EC2 instances concurrently, with strong consistency and low-latency access. Which AWS storage solution should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon EFS
Option B is correct because Amazon EFS provides a fully managed NFS file system that can be mounted by multiple EC2 instances concurrently with strong consistency. Option A is wrong because EBS volumes can only be attached to one instance at a time. Option C is wrong because S3 is object storage, not a file system. Option D is wrong because Storage Gateway file gateway provides file access to S3 but adds latency and consistency trade-offs.
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.
✗
AWS Storage Gateway File Gateway
Why it's wrong here
File Gateway provides file access to S3 but adds latency and is not a native shared file system.
✓
Amazon EFS
Why this is correct
EFS provides a fully managed, scalable NFS file system that can be mounted by many instances with strong consistency.
Related concept
Read the scenario before looking for a memorised answer.
✗
Amazon EBS with multi-attach enabled
Why it's wrong here
EBS multi-attach is limited to a few instances and is not a shared file system.
✗
Amazon S3
Why it's wrong here
S3 is object storage, not a file system, and does not support file locking or low-latency access.
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.
