Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Database Migration Service (DMS): Migrates databases to AWS with minimal downtime
Why this is correct
AWS DMS is designed for migrating databases to AWS while minimizing downtime, supporting both homogeneous and heterogeneous migrations.
AWS Snowball: Transfers large datasets via physical devices
Why this is correct
AWS Snowball uses physical storage devices to transfer large amounts of data to/from AWS, bypassing slow or unreliable networks.
AWS DataSync: Automates and accelerates online data transfer to/from AWS storage
Why this is correct
AWS DataSync automates and accelerates moving data between on-premises storage and AWS storage services like S3 or EFS.
AWS Database Migration Service (DMS): Transfers large datasets via physical devices
Why it's wrong here
Incorrect — AWS DMS is for database migration, not physical device transfer; AWS Snowball handles physical data transfer.
AWS Snowball: Migrates databases to AWS with minimal downtime
Why it's wrong here
Incorrect — AWS Snowball is for bulk data transfer via devices, not for live database migration; AWS DMS is the correct tool.
AWS DataSync: Converts database schema to target platform
Why it's wrong here
Incorrect — AWS DataSync is for data transfer, not schema conversion; the AWS Schema Conversion Tool (SCT) handles schema conversion.
