AWS Certified Cloud Practitioner (CLF-C02) — Question 212

A company wants to query its server logs to gain insights about its customers’ experiences.

Which AWS service will store this data MOST cost-effectively?

Answer options

• A. Amazon Aurora
• B. Amazon Elastic File System (Amazon EFS)
• C. Amazon Elastic Block Store (Amazon EBS)
• D. Amazon S3

Correct answer: D

Explanation

Amazon S3 is the most cost-effective option for storing large volumes of data, such as server logs, due to its low storage costs and scalability. The other options, like Amazon Aurora, EFS, and EBS, are designed for different use cases involving databases or block storage, making them less economical for simple log storage.
