AWS Certified Solutions Architect – Associate (SAA-C02) — Question 296

A company receives 10 TB of instrumentation data each day from several machines located at a single factory. The data consists of JSON files stored on a storage area network (SAN) in an on-premises data center located within the factory. The company wants to send this data to Amazon S3 where it can be accessed by several additional systems that provide critical near-real-lime analytics. A secure transfer is important because the data is considered sensitive.
Which solution offers the MOST reliable data transfer?

Answer options

• A. AWS DataSync over public internet
• B. AWS DataSync over AWS Direct Connect
• C. AWS Database Migration Service (AWS DMS) over public internet
• D. AWS Database Migration Service (AWS DMS) over AWS Direct Connect

Correct answer: B

Explanation

AWS DataSync is the ideal service for transferring large volumes of unstructured file data, such as JSON files on a SAN, directly to Amazon S3, whereas AWS Database Migration Service (AWS DMS) is designed for database migrations. Furthermore, using AWS Direct Connect provides a dedicated, secure, and highly reliable network connection for transferring 10 TB of daily sensitive data, making it superior to the public internet.
