Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 487 discussion

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.

For VMs use agentless unless you need to track network

D. 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. ✅ Fulfills the Migration Evaluator requirement (assessment and Quick Insights). ✅ Fulfills the dependency mapping requirement (via Application Discovery Agent). ✅ Uses Migration Hub to visualize dependencies. ✅ Provides a Quick Insights assessment report, as the question requires. ✅ Minimal operational overhead, since you're allowed to install software freely

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.

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

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

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.

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.

I think option A is correct

"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"

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

the key word here is "many" VMs, hence C.

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.

Option C: Use Agentless for VMs

"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.

B is the correct answer becuase you would use migration evaluater
