CLF-C02 Practice Question 41: Migration Business Case

AWS Certified Cloud Practitioner (CLF-C02) · Test 5 · question 1 of 10

Cloud Conceptsmedium

Before approving a migration of about 800 on-premises servers, a company's CFO wants a data-driven business case. It must compare what the company spends on its current infrastructure with projected AWS costs, based on how much those servers are actually used today. Which AWS offering is designed to produce this?

Show answer and explanation

Answer:

B. Migration Evaluator

Migration Evaluator is built to create a data-driven business case for moving to AWS. It discovers the current environment (for example with an agentless collector deployed on premises), measures how servers are provisioned and actually used, and projects a right-sized AWS target state and its cost. That total cost of ownership comparison is what the CFO is asking for, and because it uses real utilization rather than guesses, over-provisioned servers are not simply copied into the cloud estimate.

Option A, AWS Application Migration Service, carries out a lift-and-shift migration of servers into Amazon EC2. It is used *after* the decision to migrate, not to justify it. Option C, AWS Cost Explorer, analyzes spend and usage that has already happened in an AWS account, so it has nothing to say about on-premises servers that have not moved yet. Option D, the AWS Well-Architected Tool, reviews a workload against architectural best practices. It does not model migration costs.
