Community Votes
100% of anonymous learners picked answer A. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The question tests the specific function of discovery tools versus migration or storage connectors, with the trap being confusion between inventory collection and data transfer.
AWS Application Discovery Service is the correct tool for gathering usage and configuration data from on-premises servers during migration planning.
Learners often select AWS Database Migration Service (DMS) because it handles databases, but DMS is for active migration, not initial assessment and data gathering.

Expert Analysis
Why the Answer Is Correct
AWS Application Discovery Service is explicitly designed to help customers plan migration projects by collecting information about their on-premises data centers. It gathers server dependency mapping, hardware specifications, and utilization metrics, which are essential for sizing and strategy before actual migration begins.Why the Other Options Are Wrong
AWS DataSync is a data transfer service optimized for moving large datasets over long distances, not for discovering server configurations. AWS Storage Gateway connects on-premises applications to cloud storage for backup and archiving, serving as a hybrid storage solution rather than a discovery tool. AWS Database Migration Service (DMS) is used to migrate database schemas and data, requiring existing knowledge of the source environment rather than helping to gather it.Community Comment Notes
The community consensus strongly supports option A, with commenters noting that Application Discovery Service collects 'usage and configuration data' necessary for migration planning. As user alokdixit2006 noted, this service helps 'plan your migration... by collecting usage and configuration data,' confirming its role in the assessment phase.Official Reference
Exam Strategy
Differentiate between services used for 'assessment/planning' (Discovery Service) versus those used for 'execution/migration' (DMS, DataSync). Always look for keywords like 'gather information', 'assess', or 'plan' to identify discovery tasks.
Frequently Asked Questions
Can I use AWS DataSync to discover my on-premises servers?
No. DataSync moves data; it does not inventory or assess server configurations and dependencies.
Is Application Discovery Service free?
Yes, the agent and server components are free, though you pay for any EC2 instances used to run the discovery appliance.
