AWS Certified Solutions Architect – Associate (SAA-C03) — Question 102

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-time 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

The correct answer is B, as AWS DataSync over AWS Direct Connect provides a dedicated, secure, and high-bandwidth connection that ensures reliable data transfer. Option A is less secure since it uses the public internet, which may introduce latency and potential data breaches. Options C and D involve AWS DMS, which is not the best fit for transferring large volumes of instrumentation data compared to DataSync.
