Question Overview

Selecting the two correct combinations of a migration, backup, or DR service and its role.

Requirements to satisfy
  • 1「migration, backup, or disaster recovery service and its role」Correctly map the roles of DMS / SCT / Backup / DRS
Per-option explanation
ACorrect

AWS DMS - migrates a database to AWS with minimal downtime.

Correct. AWS DMS (AWS Database Migration Service) is a managed service that migrates a database to AWS with minimal downtime while keeping the source database running.

BIncorrect

AWS Backup - converts schemas between different database engines.

Schema conversion between different engines is the role of AWS SCT.

AWS Backup is a centralized backup management service, so the description is wrong and this is incorrect.

CCorrect

AWS Backup - centrally manages backups of multiple services by policy.

Correct. AWS Backup centrally automates and manages backups of multiple services based on policy.

DIncorrect

AWS DMS - ships physical devices to transfer large volumes of data.

Offline transfer by loading data onto physical devices and shipping them is the role of AWS Snow Family.

AWS DMS is a service that migrates databases by replicating them over the network, so the combination is wrong and this is incorrect.

EIncorrect

AWS SCT - continuously replicates and synchronizes data during the migration.

Continuous data replication and synchronization during the migration is the role of AWS DMS.

AWS SCT (AWS Schema Conversion Tool) is a tool that converts schemas and code between different engines and is not a service that keeps moving the data itself, so it is incorrect. The division of SCT (conversion) plus DMS (migration) is the standard.

Key Takeaway

Mapping: DMS = database migration / SCT = schema conversion (heterogeneous) / AWS Backup = centralized backup of multiple services / Elastic Disaster Recovery = recovery during a disaster. Distinguish migration (DMS/SCT), protection (Backup), and recovery (DRS).
