Question #885
A company is migrating its on-premises infrastructure to AWS. The environment includes a mix of Windows and Linux servers, both virtualized and bare-metal, along with various database types. The company lacks a comprehensive inventory and needs to analyze application dependencies and network traffic patterns to optimize resource allocation during migration. A solutions architect must gather this data to create an effective migration strategy. Which approach addresses these requirements?
Use AWS Migration Evaluator to collect environment data. Deploy the AWS Application Discovery Service Agentless Collector to aggregate server details and generate a Migration Evaluator report.
Use AWS Migration Hub and install AWS Application Discovery Agents on all servers. Configure the Migration Hub Strategy Recommendations collector to analyze dependencies and produce a rightsizing report.
Run the AWS Application Discovery Service Agentless Collector on-premises and integrate it with AWS Migration Hub. Use AWS Application Migration Service to group resources and generate a Strategy Recommendations report.
Import the on-premises server inventory into AWS Migration Hub using the import tool. Execute Migration Hub Strategy Recommendations to create a migration plan based on the imported data.
Explanation
Answer B is correct because:
1. AWS Application Discovery Agents collect comprehensive system configuration, performance data, and network dependencies by running directly on servers (both Windows and Linux). This addresses the lack of inventory and dependency analysis.
2. AWS Migration Hub aggregates this data and uses Strategy Recommendations to generate rightsizing reports, ensuring optimal resource allocation during migration.
Other options are incorrect because:
- A relies on an agentless collector, which may miss application-level dependencies.
- C uses the agentless collector and Application Migration Service, which focuses on server migration rather than dependency analysis.
- D assumes an existing inventory (which the company lacks) and skips dependency mapping.
Key Points: Use agent-based discovery for detailed dependency analysis; Migration Hub + Strategy Recommendations enable rightsizing and migration planning.
Answer
The correct answer is: B
