Salesforce Certified Platform App Builder — Question 69

What is true about external lookup relationship fields? (Choose all that apply.)

Answer options

• A. Lookup filters are available for external lookup relationship fields.
• B. Cascade-delete isn't available for external object relationships.
• C. Only objects that have a custom field with the External ID and Unique attributes are available as parent objects in indirect lookup relationships.
• D. All of the above.

Correct answer: B, C

Explanation

Option B is correct because cascade-delete is not applicable to external object relationships, as they are designed to maintain data integrity across different systems. Option C is also correct, as indirect lookup relationships specifically require parent objects to have a custom field marked as both External ID and Unique. Option A is incorrect because lookup filters are not supported in external lookup relationship fields.
