Exam MB-300 topic 1 question 28 discussion

Use the processing group options to either import or export data. For import, you first import the data to a staging table, where you can clean or transform the data as you require. You should validate that the data appears accurate, and that the reference data is mapped correctly. You then migrate the data from the staging table to the target table. You should validate that the entity appears accurate in the target table. For export, you also move the data from the source to a staging table, where you can clean or transform the data as you require. https://learn.microsoft.com/en-us/dynamicsax-2012/appuser-itpro/data-import-export-framework-user-guide-dixf-dmf#architecture

The Data Import/Export Framework creates a staging table for each entity in the Microsoft Dynamics AX database where the target table resides. Data that is being migrated is first moved to the staging table. There, you can verify the data, and perform any cleanup or conversion that is required. You can then move the data to the target table or export it. -https://docs.microsoft.com/en-us/dynamicsax-2012/appuser-itpro/data-import-export-framework-user-guide-dixf-dmf#architecture

Correct, that’s what the tool does

Correct Answer is D

Correct Answer is D because it is about Data Import/Export Framework (DIXF) not DMT.

I think it is C https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/migration-upgrade/data-migration-tool "You can use the Microsoft Dynamics AX 2009 Data migration tool (DMT) to migrate your data from AX 2009 to Finance and Operations. Using the DMT is the only supported upgrade path from AX 2009. The DMT helps you find and fill gaps between the table schemas for each version, as well as helping you move your data."
