Community Insight

The question tests knowledge of AWS migration tools, specifically identifying DataSync as the correct solution for moving data between AWS storage services, distinct from Direct Connect or S3.

AWS DataSync is the service designed to migrate data between AWS storage services and on-premises locations. This page establishes that DataSync automates and accelerates data transfer tasks across these environments.

Learners often confuse AWS DataSync with Amazon S3, which is a storage service itself rather than a migration tool. Others may mistakenly select AWS Direct Connect, which provides network connectivity but does not handle the data movement logic.

Expert Analysis

Why the Answer Is Correct

AWS DataSync is explicitly designed to automate data transfer between on-premises storage and AWS storage services (such as Amazon S3, Amazon EFS, and Amazon FSx). It handles the complexities of data movement, including optimization, scheduling, and security, making it the correct choice for migrating data between AWS storage services.

Why the Other Options Are Wrong

Amazon S3 (Option D) is an object storage service, not a tool for migrating data. AWS Direct Connect (Option B) provides dedicated network connections but does not perform the actual data migration. AWS Lake Formation (Option C) is used for setting up secure data lakes, not for general data migration between storage services.

Community Comment Notes

Community comments confirm that AWS DataSync supports transferring data between AWS storage services. One user noted that DataSync works in three cases, including transferring data between AWS storage services, aligning with the official documentation.

Exam Strategy

When asked about data migration between AWS services, look for AWS DataSync. Remember that Direct Connect is for networking, while services like S3 are storage targets, not migration tools.

Frequently Asked Questions

Why isn't Amazon S3 the correct answer?

S3 is a storage service, not a migration tool. DataSync moves data TO and FROM S3.

Does DataSync work only for on-premises?

No, DataSync also transfers data between different AWS storage services like S3 and EFS.
