- A
AWS Storage Gateway File Gateway
This service is designed exactly for this use case: it provides a local VM that caches frequently accessed files on premises, presents SMB/NFS shares to applications, and stores the primary data in Amazon S3. It offers low-latency access through the cache and is managed from the AWS Management Console.
- B
Amazon FSx for Windows File Server
Why wrong: FSx for Windows File Server is a fully managed native Windows file server running in AWS. While it supports SMB protocol, it does not include an on-premises caching component. Access from on-premises requires a network connection (VPN or Direct Connect) with no local cache, which would introduce latency and recurring egress costs for every file operation.
- C
AWS DataSync
Why wrong: AWS DataSync is designed for large-scale data transfers from on-premises to AWS (or vice versa) over the internet or Direct Connect. It can copy the initial 10 TB to S3 efficiently, but it does not provide ongoing low-latency file access with local caching. After the transfer is complete, DataSync is not used for daily read/write operations.
- D
Amazon S3 with AWS Direct Connect
Why wrong: While Direct Connect provides a dedicated, high-bandwidth network connection from on-premises to AWS, there is no local cache. Each file read/write would require a round trip over the Direct Connect link to S3, resulting in latencies that typically exceed 5 milliseconds for small I/O operations. Additionally, all data movements incur egress charges, and the solution does not provide a standard SMB file share interface.
Quick Answer
The answer is AWS Storage Gateway File Gateway, which is the correct choice because it provides a hybrid cloud storage service that maintains an on-premises cache of recently accessed data for low-latency access to Amazon S3, targeting sub-5 millisecond response times for cached files. This service supports standard SMB file-sharing protocols, integrates seamlessly with S3 for durable and scalable storage, and is fully manageable through the AWS Management Console, meeting all the requirements for minimizing egress costs while keeping frequently used files local. On the AWS Certified Cloud Practitioner CLF-C02 exam, this scenario tests your understanding of hybrid cloud storage patterns and the specific role of File Gateway in bridging on-premises environments with AWS cloud storage. A common trap is confusing File Gateway with Volume Gateway or Tape Gateway, but remember: File Gateway is for file-based access with SMB/NFS and a local cache, while the others serve block or tape workloads. Memory tip: “File Gateway = Files + Local Cache + S3.”
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. A key principle to apply: file Gateway provides SMB/NFS shares to on-premises applications.. 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 a legacy on-premises file server that stores 10 TB of shared documents used by a team of 50 employees. The company wants to migrate this data to Amazon S3 to benefit from durable, scalable storage. However, the team requires low-latency access to frequently used files (less than 5 milliseconds latency) because the application reads and writes files multiple times per second. The company also wants to maintain a local cache of recently accessed files on premises to reduce latency and minimize egress costs. The entire solution should be managed through the AWS Management Console and support standard file-sharing protocols like SMB. Which AWS service should the company use to meet these requirements?

Correct answer & explanation
AWS Storage Gateway File Gateway
AWS Storage Gateway File Gateway is the correct choice because it provides a hybrid cloud storage service that enables low-latency, on-premises access to frequently used files by maintaining a local cache of recently accessed data. It supports the SMB protocol for standard file sharing, integrates with Amazon S3 for durable, scalable storage, and can be managed through the AWS Management Console. The local cache reduces both latency (targeting sub-5 ms for cached data) and egress costs by serving reads from the on-premises cache instead of fetching from S3.
Key principle: File Gateway provides SMB/NFS shares to on-premises applications.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Storage Gateway File Gateway with Amazon FSx for Windows File Server, assuming both provide on-premises caching, but FSx is a cloud-only service without a local cache, making it unsuitable for sub-5 ms latency requirements from on-premises clients.
Detailed technical explanation
How to think about this question
Under the hood, AWS Storage Gateway File Gateway uses a local VM or hardware appliance that caches recently accessed file data on-premises, serving reads from the cache with sub-millisecond latency while asynchronously uploading data to S3. The gateway supports SMB protocol versions 2.0 and 3.0, and it uses a write-back cache to minimize write latency; however, writes are acknowledged locally before being committed to S3, which can introduce a small risk of data loss if the gateway fails before upload completes. In real-world scenarios, this architecture is ideal for workloads like media editing or collaborative document sharing where low latency is critical but data durability is ensured through eventual consistency with S3.
KKey Concepts to Remember
- File Gateway provides SMB/NFS shares to on-premises applications.
- It caches frequently accessed data locally for low-latency access.
- Primary data is stored durably and scalably in Amazon S3.
- Managed via the AWS Management Console.
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
File Gateway provides SMB/NFS shares to on-premises applications.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
