Which AWS service tracks application migration progress in one place?
Short answer
D AWS Migration Hub provides a single location to plan and track the progress of each application migration.
Question
Key Takeaways
The question tests whether you can separate the migration tracking/planning plane (Migration Hub) from discovery (ADS) and execution (MGN) — the trap is option B, which merely contains the word "migration".
AWS Migration Hub is the service that provides a single location to plan, track, and visualize the status of each application migration to AWS. This page confirms why option D is correct and how it differs from Application Discovery Service, Application Migration Service, and Service Catalog.
Common mistake: Picking AWS Application Migration Service (B) because its name contains "migration" and it does the actual rehosting — but the question asks which service provides a single location to track migration progress, which is Migration Hub, not the service that performs the replication.
Expert Analysis
Why the Answer Is Correct
AWS Migration Hub is described by AWS as the single place to discover existing servers, plan migrations, and track the status of each application migration. That wording maps exactly onto the question's phrase "single location to track the progress of application migrations." Migration Hub aggregates data from AWS Application Discovery Service and receives status updates from migration tools such as AWS Application Migration Service and AWS Database Migration Service, then presents per-application progress in one dashboard. Because the question is about visibility and progress tracking across a migration portfolio, not about performing the migration itself, Migration Hub is the only option that fits. The community vote record (D: 100) and every comment agree with this reading.
Why the Other Options Are Wrong
AWS Application Discovery Service (A) is the agentless/agent-based collector that inventories on-premises servers, dependencies, and utilization data; it feeds Migration Hub but does not itself track migration progress. AWS Application Migration Service (B) is the lift-and-shift engine that replicates and cuts over source servers to AWS — it executes migrations rather than reporting portfolio-level status. AWS Service Catalog (C) lets organizations curate and provision approved IT products into portfolios for end users, so it has no migration tracking function at all; the word "Catalog" alongside a portfolio concept is the distractor here. Only Migration Hub answers the "single location" requirement in the question stem.
Community Comment Notes
Consensus in the comment thread is unanimous for D, and the referenced material is the official Migration Hub user guide. One learner pasted the AWS definition itself, describing how Migration Hub "provides a single place to discover your existing servers, plan migrations, and track the status of each application migration." As alokdixit2006 put it, Migration Hub helps "plan, execute, and track migrations to AWS (single place)," and red_panda simply concluded "D is correct." BShelat and another commenter both cited the whatishub documentation page, while BigMF pointed to the AWS Migration Hub features page. No commenter defended A, B, or C.

Exam Strategy
Memorize the migration trio by verb: Application Discovery Service = discover/inventory, Application Migration Service (MGN) = move/replicate servers, Migration Hub = plan and track the whole portfolio in one place. When a stem contains "single location," "track," or "status of each application," the answer is Migration Hub.
