Which AWS service helps you inventory on-prem workloads and dependencies before migration?

• A. AWS Migration Hub
• B. Amazon S3
• C. AWS Application Discovery Service.
• D. AWS Config

Answer: (C)

Planning a migration starts with a complete picture of what sits on premises and how those pieces depend on one another. AWS Application Discovery Service is built for that purpose: it automatically inventories on-premises servers, tells you what applications are running, and maps the dependencies between components. This gives you the data you need to plan migration waves, estimate interdependencies, and decide where each workload should land in AWS.

Migration Hub is about centralizing the progress of migrations across multiple tools, not about discovering or inventorying on-premises environments. AWS Config tracks configurations and changes of AWS resources, not on-prem workloads. Amazon S3 is a storage service and doesn’t perform discovery or dependency mapping.
