SAP-C02 Question 78
Single answerA company is migrating its on-premises application to AWS. The application requires a shared file system that supports hundreds of concurrent connections, low latency, and the ability to scale storage capacity dynamically as needed. Additionally, the company requires encryption for data at rest and in transit. Which AWS service would best meet these requirements?
- A
Amazon EBS (Elastic Block Store)
- B
Amazon S3 (Simple Storage Service)
- C
Amazon EFS (Elastic File System)
- D
AWS Storage Gateway
Show answer and explanation
Correct answer: C
Explanation
Amazon EFS is the best choice for applications that need a scalable, shared file system with low latency and support for hundreds of concurrent connections. It also provides encryption for data at rest and in transit, making it suitable for secure workloads. Other options, such as Amazon EBS and S3, do not meet the requirements for a shared file system, and AWS Storage Gateway serves a different use case.
- A. Incorrect.
Amazon EBS is a block storage service optimized for single instance usage, not for shared file systems. It does not support hundreds of concurrent connections.
- B. Incorrect.
Amazon S3 is an object storage service, not a file system. It is not designed for use cases requiring shared file systems or low-latency access.
- C. Correct.
Amazon EFS is a fully managed, scalable file storage system that supports hundreds or thousands of concurrent connections, provides low latency, and supports encryption for both data at rest and in transit. This option meets all the requirements.
- D. Incorrect.
AWS Storage Gateway is primarily designed for hybrid cloud storage use cases, such as extending on-premises storage to AWS. It does not provide the required shared file system capabilities or dynamic scalability.
