SAP-C02 Question 309
Single answerA media company is building a data lake architecture on AWS to store and process large volumes of unstructured data such as videos, images, and logs. The company wants a cost-effective storage solution that allows them to query the data directly using analytics services like Amazon Athena, while also ensuring high durability and scalability. Which AWS storage solution should the company use to meet these requirements?
- A
Amazon S3 Standard
- B
Amazon EBS (Elastic Block Store)
- C
Amazon EFS (Elastic File System)
- D
Amazon Glacier Deep Archive
Show answer and explanation
Correct answer: A
Explanation
Amazon S3 Standard is the best choice for building a data lake on AWS. It provides cost-effective, scalable, and durable object storage and integrates directly with services like Amazon Athena for querying data without requiring additional data movement. Other options like Amazon EBS, EFS, and Glacier Deep Archive are either not optimized for unstructured data storage or unsuitable for analytics use cases.
- A. Correct.
Amazon S3 Standard is the ideal solution for a data lake as it provides highly durable, scalable, and cost-effective object storage. It integrates seamlessly with analytics services like Amazon Athena, allowing direct querying of data.
- B. Incorrect.
Amazon EBS is a block storage solution designed for use with EC2 instances. It is not suitable for a data lake, as it is not optimized for unstructured data storage or direct querying by analytics services.
- C. Incorrect.
Amazon EFS is a file storage service for use with Linux-based workloads. While it offers scalability, it is more expensive compared to Amazon S3 for storing large volumes of unstructured data and is not optimized for data lake use cases.
- D. Incorrect.
Amazon Glacier Deep Archive is a low-cost storage class designed for long-term archival data. It is not suitable for frequent access or analytics use cases, as data retrieval times can take hours.
