Exam Question Walkthrough: Secure File Transfer with AWS
Explore a sample AWS SAA-C03 exam question on secure file transfer, understand why the answer is AWS DataSync, and avoid common traps.
A common decision that trips many candidates is choosing the right service for secure file transfers. Understanding AWS services and their specific use cases is crucial for success.
The question
A large enterprise is looking to implement a secure method for transferring files between its on-premises data center and AWS. They require encryption and a way to guarantee data integrity. Which AWS service should they use?
- A. AWS DataSync
- B. AWS Transfer Family
- C. Amazon S3 with Transfer Acceleration
- D. AWS Snowball
Think before you scroll
Before making a choice, consider the requirements: secure transfer, encryption, and data integrity. Each option has different strengths and weaknesses related to these needs.
The answer
The correct option is A. AWS DataSync. AWS DataSync is specifically designed for efficient and secure data transfer between on-premises storage and AWS. It provides encryption in transit and at rest, as well as data integrity verification, making it the best fit for this scenario.
Why the other options lose
- B. AWS Transfer Family: This service is designed primarily for SFTP and FTP transfers. While it offers secure file transfer capabilities, it is not optimized for bulk data transfer like DataSync. Thus, it does not meet the enterprise's needs for secure bulk transfers.
- C. Amazon S3 with Transfer Acceleration: This service focuses on speeding up uploads and downloads to S3 but lacks built-in encryption and integrity guarantees for secure file transfers. It is not tailored for the specific security requirements outlined in the question.
- D. AWS Snowball: Snowball is a physical data transport solution for large-scale data migrations. It is not intended for regular secure file transfers and is better suited for moving vast amounts of data into AWS, making it an impractical choice for this situation.
The concept behind it
The principle at play here is selecting the right AWS service based on specific requirements. For secure file transfers, AWS DataSync is designed with encryption and integrity in mind, making it a go-to solution for enterprises needing to transfer data securely.
Exam trap to remember
Always match the service capabilities to the specific requirements. Look for keywords like "encryption" and "data integrity" to guide your selection.
