SAP-C02 Question #648: Real Exam Question with Answer & Explanation

Question

A company is migrating to the cloud. It wants to evaluate the configurations of virtual machines in its existing data center environment to ensure that it can size new Amazon EC2 instances accurately. The company wants to collect metrics, such as CPU, memory, and disk utilization, and it needs an inventory of what processes are running on each instance. The company would also like to monitor network connections to map communications between servers. Which would enable the collection of this data MOST cost effectively?

Options

• AUse AWS Application Discovery Service and deploy the data collection agent to each virtual
• BConfigure the Amazon CloudWatch agent on all servers within the local environment and publish
• CUse AWS Application Discovery Service and enable agentless discovery in the existing
• DEnable AWS Application Discovery Service in the AWS Management Console and configure the

Explanation

To cost-effectively collect detailed CPU, memory, disk utilization, process inventory, and network connections from on-premises VMs for EC2 sizing, deploy the agent-based AWS Application Discovery Service.

Common mistakes.

• B. While the Amazon CloudWatch agent can collect some system metrics, it is primarily for operational monitoring and would require extensive custom configuration to gather a full inventory of running processes and map network connections in the comprehensive way that Application Discovery Service does for migration assessment.
• C. Agentless discovery in AWS Application Discovery Service typically gathers basic server configuration and network dependencies but provides less granular performance metrics (like memory and disk utilization over time) and process inventory compared to the agent-based method.
• D. This option is essentially describing the same approach as A, but A is phrased more directly as the action to take. Using the agent for AWS Application Discovery Service is the correct method, implying A or D would be suitable.
