Question #: 78
Topic #: 4

An App Builder is loading the data into salesforce. To link the new records back to the legacy system, a field will be used to track the legacy ID on the account object. For future data loads this ID will be used when upserting records. Which field attribute should be selected? Choose 2 answers

AUnique

BRequired

CExternal ID

DText (encrypted)

Show Suggested Answer

Suggested Answer: A, C

The field attribute that should be selected are Unique and External ID. Unique means that the field will not allow duplicate values. External ID means that the field can be used as a foreign key for data imports and upserts. Option B is incorrect because Required means that the field must have a value and cannot be left blank, which is not necessary for this requirement. Option D is incorrect because Text (encrypted) means that the field will store sensitive data in an encrypted format, which is not necessary for this requirement.

I think we might need to use the External ID for linking the legacy system, but I'm not entirely sure about the second option.
