SAP-C02Domain 4: Accelerate Workload Migration and ModernizationMigration & ModernizationmediumSingle choice
200 on-premises Windows and Linux servers need lift-and-shift migration to EC2 with minimal downtime and continuous replication. Which service is purpose-built for server rehosting?
A.AWS Database Migration Service
DMS migrates databases, not whole servers.
B.AWS Application Migration Service (MGN)
Server rehosting = MGN. Correct.
C.AWS DataSync
DataSync transfers files — doesn't capture OS/app stacks.
D.AWS Snowball
Snowball is offline data transfer — not live replication.
Why this answer
MGN is the block-level replication service for rehosting servers (lift-and-shift) — continuous replication, short cutover windows, test instances. DMS = databases; DataSync = file/object data; Snowball = offline bulk transfer.
