Select existing workloads and processes for potential migration. Determine the optimal migration approach for existing workloads.

Short answer

A Install the AWS Application Discovery Agent on each VM, then view dependencies and download the Quick Insights report from Migration Hub.

Question

A company plans to migrate many VMs from an on-premises environment to AWS. The company requires an initial assessment of the on-premises environment before the migration, a visualization of the dependencies between applications that run on the VMs, and a report that provides an assessment of the on-premises environment. To get this information, the company has initiated a Migration Evaluator assessment request. The company has the ability to install collector software in its on-premises environment without any constraints Which solution will provide the company with the required information with the LEAST operational overhead?
  1. Install the AWS Application Discovery Agent on each on-premises VM. After the data collection period ends, use AWS Migration Hub to view the application dependencies. Download the Quick insights assessment report from Migration Hub. Correct Answer
  2. Install the Migration Evaluator Collector on each on-premises VM. After the data collection period ends, use Migration Evaluator to view the application dependencies. Download and export the discovered server list from Migration Evaluator. Upload the list to Amazon QuickSight When the QuickSight report is generated, download the Quick Insights assessment report.
  3. Setup the AWS Application Discovery Service Agentless Collector in the on-premises environment. After the data collection period ends, use AWS Migration Hub to view the application dependencies. Export the discovered server list from Application Discovery Service. Upload the list to Migration Evaluator. When the Migration Evaluator report is generated, download the Quick Insights assessment.
  4. Set up the Migration Evaluator Collector in the on-premises environment. Install the AWS Application Discovery Agent on each VM. After the data collection period ends, use AWS Migration Hub to view the application dependencies. Download the Quick Insights assessment report from Migration Evaluator.

Key Takeaways

The Application Discovery Agent installed on each VM feeds data straight into Migration Hub, where the dependency visualization and the Quick Insights report are available directly, so no export, re-upload, or QuickSight report generation step is needed.

The company needs an on-premises assessment, a visualization of application dependencies running on its VMs, and an assessment report, and it has already requested a Migration Evaluator assessment. It can install collector software without constraint and wants the least operational overhead.

Common mistake: Assuming the Agentless Collector path is simpler because it needs no agent on every VM. That option still requires exporting the discovered server list from Application Discovery Service, uploading it to Migration Evaluator, and waiting for a new report, which is more steps than reading the report directly from Migration Hub.

Expert Analysis

Why the Answer Is Correct

The AWS Application Discovery Agent is installed on each on-premises VM and reports system configuration, performance, and TCP network connections to Application Discovery Service. Those results surface in AWS Migration Hub, which is where application dependencies are viewed and where the Quick Insights assessment report is downloaded directly. Because the data flows automatically into Migration Hub, the whole path is install-then-read, which is the lowest operational overhead of the options.

Why the Other Options Are Wrong

B: Exporting the discovered server list, uploading it to Amazon QuickSight, and waiting for a Quick Insights report adds a manual export, an external analytics tool, and a second rendering step. C: The Agentless Collector is useful for VMware environments but requires exporting the server list from Application Discovery Service and uploading it to Migration Evaluator before a report can be produced, and it does not gather the full range of per-VM dependency data. D: Running both the Migration Evaluator Collector and the Discovery Agent duplicates collection effort for the same assessment, which is the opposite of least operational overhead.

Community Comment Notes

The community voted 65 to 29 for A over C, and the top-voted comment pointed out that option C adds an export and upload step on top of the agentless collector, plus that the agentless collector will not gather data for all dependencies. One dissenting comment preferred the Migration Evaluator Collector for cost planning, but the question asks for dependency visualization and a report, which is what Migration Hub provides directly.

    Option C is not the least operation overhead. it requires Application Discovery agentless Collector + Export & Upload of the report. also, Discovery agentless will not gather data for all dependencies.
  2. 5ehjry6sktukliyliuliykutjhy 👍 8 Answered C
    For VMs use agentless unless you need to track network

    "To get this information, the company has initiated a Migration Evaluator assessment request. The company has the ability to install collector software in its on-premises environment without any constraints", so I understand from the question that the next step would be installing the AWS Application Discovery Agent on each on-premises VM, so for me the answer is A.
  4. zapper1234 👍 4
    B is the correct answer becuase you would use migration evaluater

    "AGENT-BASED discovery can be performed by deploying the AWS Application Discovery Agent on each of your VMs and physical servers. The agent installer is available for Windows and Linux operating systems. It collects static configuration data, detailed time-series system-performance information, INBOUND AND OUTBOUND NETWORK CONNECTIONS, and processes that are running."

    The question clearly states, "The company has the ability to install collector software in its on-premises environment without any constraints"
  2. toma 👍 2
    it should be A, as you can see on this link: https://aws.amazon.com/migration-evaluator/ agentless collector should be used, it is simple.
  3. 0b43291 👍 1 Answered A
    Option A is the answer with the least operational overhead because it leverages the AWS Application Discovery Agent, which can be installed on each on-premises VM to collect configuration data, performance metrics, and application dependencies. AWS Migration Hub integrates with Application Discovery Service, providing a centralized view of discovered servers, dependencies, and migration status. Migration Hub allows visualizing application dependencies and provides the Quick Insights assessment report, fulfilling all requirements. By using a single agent and Migration Hub's built-in capabilities, Option A minimizes operational overhead and provides a streamlined solution for the required information.

    This solution requires minimal operational overhead as it only involves installing a small agent (AWS Application Discovery Agent) on each VM, which can be done without disrupting the environment. The AWS Application Discovery Service is an agentless collector that can discover resources in your organization without requiring any configuration or agent installation. However, in this case, the company has already initiated a Migration Evaluator assessment request and can use the built-in capabilities of Migration Hub to collect information about their on-premises environment.

    The solution that provides the company with the required information with the least operational overhead is B: Install the Migration Evaluator Collector on each on-premises VM. This method allows for efficient data collection, enabling the use of Migration Evaluator to visualize application dependencies and download the Quick Insights assessment report easily. This approach minimizes complexity compared to options that require multiple software installations or data transfers between services, thus reducing operational overhead significantly

    The Migration Evaluator Collector is better for high-level assessment and cost planning, while the Application Discovery Agentless Collector is suited for detailed dependency analysis between applications and VMs.

    They have the capability of accepting installs on their VM so I will go with A. It can not be the agent less because there is no mention that they can not allow installs on their VMs

    Option C is correct. https://aws.amazon.com/about-aws/whats-new/2024/11/network-connections-aws-application-discovery-service-agentless-collector/?nc1=h_ls
  9. asquared16 👍 1 Answered C
    the key word here is "many" VMs, hence C.
  10. 5ehjry6sktukliyliuliykutjhy 👍 1
    Option C: Use Agentless for VMs
  11. Danm86 👍 1
    I think option A is correct
