Q50 — AWS SAA-C03 Ch.1

Question 50 of 65 | ← Chapter 1

Q50. 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?

Correct Answer: B. AWS DataSync over AWS Direct Connect

Explanation

To ensure the most reliable and secure data transfer of the sensitive JSON files from an on-premises data center to Amazon S3, the best solution is option B: AWS DataSync over AWS Direct Connect. Here's why this solution is the most reliable and secure: 1. AWS DataSync: AWS DataSync is a data transfer service specifically designed for securely transferring large amounts of data between on-premises storage and AWS services. It provides optimized network utilization, data integrity checks, and automatic error recovery, ensuring reliable and efficient data transfer. 2. AWS Direct Connect: AWS Direct Connect establishes a dedicated network connection between the on-premises data center and the AWS infrastructure. This connection bypasses the public internet, providing a more reliable, low-latency, and secure data transfer path. By combining AWS DataSync with AWS Direct Connect, the company benefits from the following: - Reliability: AWS DataSync ensures the reliable transfer of large amounts of data by using built-in error recovery mechanisms. It validates data integrity during transfer and automatically retries failed transfers, ensuring that the entire dataset is successfully transferred to Amazon S3. - Security: AWS Direct Connect provides a dedicated and private network connection between the on-premises data center and AWS, avoiding data exposure to the public internet. This enhances the security and confidentiality of the sensitive JSON files during transfer. Option A suggests using AWS DataSync over the public internet. While DataSync is reliable on its own, transferring sensitive data over the public internet introduces potential security risks and may be subject to network congestion or interruptions. Option C suggests using AWS Database Migration Service (AWS DMS) over the public internet. However, AWS DMS is primarily designed for database migration and replication, not for transferring large volumes of files. It may not provide the same level of reliability and efficiency as AWS DataSync. Option D suggests using AWS Database Migration Service (AWS DMS) over AWS Direct Connect. Similar to option C, AWS DMS is not the optimal choice for transferring large amounts of non-database files. AWS DataSync is better suited for this purpose, offering more robust data transfer capabilities.
