Which AWS service will meet this requirement?
A. AWS Migration Hub
B. AWS Database Migration Service (AWS DMS)
C. Migration Evaluator
D. AWS Application Migration Service
Show Answer

Which AWS service or feature should the company use to meet these requirements?
A. Cost allocation tags
B. AWS Organizations
C. AWS Security Hub
