Salesforce Platform Developer I (legacy) — Question 249

What are two uses for External IDs? (Choose two.)

Answer options

• A. To create relationships between records imported from an external system.
• B. To create a record in a development environment with the same Salesforce ID as in another environment
• C. To identify the sObject type in Salesforce
• D. To prevent an import from creating duplicate records using Upsert

Correct answer: A, D

Explanation

The correct answers, A and D, highlight that External IDs facilitate the creation of relationships between externally imported records and help avoid duplicate entries during data imports with Upsert. Options B and C are incorrect because B does not represent a primary function of External IDs, and C refers to identifying sObject types, which is unrelated to the purpose of External IDs.
