A company plans to migrate to the AWS Cloud. The company wants to gather information about its on-premises data center. Which AWS service should the company use to meet these requirements?

Question

Options

• AAWS Application Discovery Service
• BAWS DataSync
• CAWS Storage Gateway
• DAWS Database Migration Service (AWS DMS)

• A

• B
  2% (1)
• C
  2% (1)
• D
  4% (2)

Explanation

AWS Application Discovery Service is correct because it's specifically designed to help organizations plan cloud migrations by collecting and presenting data about their on-premises servers, including configuration, usage, and behavior - exactly what's needed before a migration.

• B (DataSync) is wrong - it's a data transfer service for moving data between on-premises storage and AWS, not for discovery or inventory.
• C (Storage Gateway) is wrong - it's a hybrid storage service that extends on-premises storage into AWS, not a discovery tool.
• D (DMS) is wrong - it migrates databases to AWS; it doesn't gather general information about a data center environment.

Memory tip: Think of it this way - before you can move anything (DataSync, DMS) or connect anything (Storage Gateway), you need to discover what you have. "Discovery" is in the name for a reason: Application Discovery Service = pre-migration inventory.
