What should the Architect do to achieve this goal?

Get Cloud Consulting needs to integrate two different systems with customer records into the Salesforce Account object. So that no duplicate records are created in Salesforce, Master Data Management will be used.

An Architect needs to determine which system is the system of record on a field level.

What should the Architect do to achieve this goal?
A . Master Data Management systems determine system of record, and the Architect doesn’t have to think about what data is controlled by what system.
B . Key stakeholders should review any fields that share the same purpose between systems to see how they will be used in Salesforce.
C . The database schema for each external system should be reviewed, and fields with different names should always be separate fields in Salesforce.
D . Any field that is an input field in either external system will be overwritten by the last record integrated and can never have a system of record.

Answer: C
