Question 85 of 100 | ← Chapter 16

Q1285. A company that has on-premises data centers in several locations wants to migrate its workloads to AWS. The company currently runs custom applications on various operating systems by using various hypervisors on hundreds of virtual machines(VMs). Some of the applications include relational databases.A solutions architect needs to assess the existing workloads and infrastructure to plan the migration to AWS. The solutions architect must track the progress of the migration.Which solution will meet these requirements in the MOST operationally-efficient way?

Correct Answer: C. Install AWS Application Discovery Service to collect details about the VMs. Use AWS Migration Hub to track the progress of the application migrations across multiple AWS services.

Explanation

The correct solution must efficiently assess existing workloads (VMs, applications, databases) and track migration progress in a multi-location, multi-hypervisor environment with minimal operational overhead.Let's evaluate each option:Correct Answer: C. Install AWS Application Discovery Service to collect details about the VMs. Use AWS Migration Hub to track the progress of the application migrations across multiple AWS services.Why Option C is Best:Comprehensive Workload Assessment:AWS Application Discovery Service (ADS) automatically collects detailed inventory data (e.g., OS, configurations, dependencies, performance metrics) from hundreds of VMs across multiple hypervisors (VMware, Hyper-V, etc.) and on-premises locations.No manual scripting required (unlike Option D).Centralized Migration Tracking:AWS Migration Hub provides a single dashboard to track migration progress across multiple AWS migration tools (e.g., AWS SMS, AWS DMS, AWS Server Migration Service, or custom scripts).Ideal for large-scale migrations (hundreds of VMs).Scalable & Operationally Efficient:ADS agents can be deployed once to collect data continuously. Migration Hub integrates with all major AWS migration services, reducing manual tracking efforts.Why Other Options Fail:A. Install AWS Application Discovery Service to collect details about the VMs. Use AWS Database Migration Service (AWS DMS) to migrate the databases.Partial Solution:While ADS is correct for assessment, AWS DMS only handles database migration--it does not track application migration progress (missing requirement).No centralized tracking for non-database workloads.B. Install AWS Application Migration Service to collect details about the existing workloads. Use AWS Database Migration Service (AWS DMS) to migrate the databases.Incorrect Assessment Tool:AWS Application Migration Service (AWS MGN) is for rehosting (lift-and-shift) migrations, not assessment.No inventory collection capability (unlike ADS).AWS DMS again fails to track migration progress.D. Use the AWS Migration Hub API to create a script that runs from a centralized server to programmatically collect all data from on-premises servers. Use AWS Application Migration Service to track migration progress.Unnecessarily Complex & Error-Prone:Manual scripting (via Migration Hub API) is time-consuming and error-prone for hundreds of VMs. AWS MGN does not track migration progress--it only performs rehosting. Migration Hub is better used directly (not via custom scripts) for tracking.Key Comparison:RequirementOption COther OptionsAssesses VMs across multiple hypervisors/locations(AWS Application Discovery Service) (B: AWS MGN for migration, not assessment; D: Manual scripting)Tracks migration progress centrally(AWS Migration Hub) (A: No tracking; B: No tracking; D: Incorrect tracking tool)Operationally efficient (minimal manual effort)(Automated discovery + built-in tracking) (D: Requires scripting; A/B: Partial solutions)Supports database + application migrations(ADS + Migration Hub work with all migration tools) (A/B: DMS only for databases; D: MGN only for rehosting)Conclusion:Option C is the only solution that:Automatically assesses VMs (ADS) across multiple hypervisors/locations. Tracks migration progress centrally (Migration Hub) for all workloads.Avoids manual scripting or partial tools (unlike A/B/D).Final Answer: C
