Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A custom field marked as External ID and Unique
Why this is correct
Correct. An External ID field allows external systems to upsert records referencing their own legacy keys.
- ✗
A standard Auto-Number field
Why it's wrong here
Incorrect. Auto-number fields are generated by Salesforce and cannot be populated with external system keys.
- ✗
A cross-object formula field
Why it's wrong here
Incorrect. Formula fields are read-only and cannot be used as target keys for data upserts.
- ✗
A master-detail relationship field
Why it's wrong here
Incorrect. Master-detail fields establish parent-child object ownership, not external integration key matching.
