- A
Amazon S3 with AWS Direct Connect
Why wrong: Direct Connect provides a private network path to S3 but S3 still requires HTTP API access — it doesn't present itself as a Windows file share.
- B
AWS Storage Gateway File Gateway (SMB)
Storage Gateway File Gateway presents S3 as an SMB file share that Windows clients can map as a network drive — transparently storing files in S3 while providing native Windows file system access.
- C
Amazon FSx for Windows File Server
Why wrong: FSx for Windows is a fully managed Windows file server in AWS — employees would need network connectivity to the FSx server, and files would live in FSx (backed by Windows Server), not directly in S3.
- D
Amazon EFS with SMB protocol
Why wrong: Amazon EFS uses NFS protocol (not SMB) and is designed for Linux clients — not Windows SMB file sharing.
Quick Answer
The answer is AWS Storage Gateway File Gateway with SMB support. This service is correct because it enables on-premises employees to mount S3 buckets as Windows file shares using standard drive mapping, allowing them to access S3 objects via Windows file system operations without migrating their existing workflows. The File Gateway caches frequently accessed data locally for low-latency performance while storing the primary data persistently in S3, bridging the gap between on-premises file servers and cloud object storage. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of hybrid storage services and how they solve real-world migration challenges; a common trap is confusing File Gateway with AWS Transfer Family or Direct Connect, which handle different protocols or connectivity layers. Remember the memory tip: “File Gateway = File share over SMB” — think of the SMB protocol as the key that lets Windows map S3 like a network drive.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. 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 wants to allow their on-premises employees to access S3 objects using Windows file system operations (drive mapping) without migrating their workflows. Which AWS service provides this capability?

Correct answer & explanation
AWS Storage Gateway File Gateway (SMB)
AWS Storage Gateway File Gateway with SMB (Server Message Block) support allows on-premises employees to mount S3 buckets as Windows file shares using standard drive mapping. This enables access to S3 objects via Windows file system operations without migrating existing workflows, as the gateway caches frequently accessed data locally while storing the primary data in S3.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon S3 with AWS Direct Connect
Why it's wrong here
Direct Connect provides a private network path to S3 but S3 still requires HTTP API access — it doesn't present itself as a Windows file share.
- ✓
AWS Storage Gateway File Gateway (SMB)
Why this is correct
Storage Gateway File Gateway presents S3 as an SMB file share that Windows clients can map as a network drive — transparently storing files in S3 while providing native Windows file system access.

Amazon FSx for Windows File Server
Why it's wrong here
FSx for Windows is a fully managed Windows file server in AWS — employees would need network connectivity to the FSx server, and files would live in FSx (backed by Windows Server), not directly in S3.
- ✗
Amazon EFS with SMB protocol
Why it's wrong here
Amazon EFS uses NFS protocol (not SMB) and is designed for Linux clients — not Windows SMB file sharing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse FSx for Windows File Server (a native Windows file system) with Storage Gateway File Gateway (which bridges S3 to SMB), or assume Direct Connect alone can expose S3 as a file system, but neither provides the SMB-to-S3 translation required for drive mapping.
Detailed technical explanation
How to think about this question
File Gateway uses the SMB protocol (versions 2.0, 2.1, and 3.0) to present S3 buckets as network shares, with local cache (up to 32 TB per gateway) for low-latency access. Under the hood, it translates SMB operations into S3 API calls (e.g., PUT, GET, DELETE) and supports features like Windows ACLs, file locking, and read-after-write consistency. A real-world scenario is a media production company that needs to edit video files stored in S3 from Windows workstations without changing their existing file-based workflows.
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.
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
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.
