D & E A Not correct, database need to be migrated to RDS, not to EC2 B - AWS Server Migration Service is a significant enhancement of EC2 VM Import. The AWS Server Migration Service provides automated, live incremental server replication and AWS Console support. For customers using EC2 VM Import for migration, we recommend using AWS Server Migration Service. C- Lease amount of downtime will not work D- is correct SMS for application server E - Is correct. DMS for data base

The question says EACH server has 500TB of attached storage. Maximum storage for RDS SQL Server is 16TB. RDS cannot be part of the solution.

Product Update: As of March 31, 2022, AWS will discontinue AWS Server Migration Service (AWS SMS). You can initiate new migration jobs using AWS SMS until January 1, 2022. Please complete your active migration projects using AWS SMS by March 31, 2022. Going forward, we recommend AWS Application Migration Service (AWS MGN) as the primary migration service for lift-and-shift migrations.
