Salesforce Certified Platform Developer II — Question 4

A company uses an external system to manage its custom account territory assignments. Every quarter, millions of Accounts may be updated in Salesforce with new Owners when the territory assignments are completed in the external system.
What is the optimal way to update the Accounts from the external system?

Answer options

• A. Bulk API
• B. SOAP API
• C. Apex REST Web Service
• D. Composite REST API

Correct answer: A

Explanation

The Bulk API is specifically designed for handling large volumes of records efficiently, making it the optimal choice for updating millions of Accounts. The SOAP API and Apex REST Web Service are better suited for smaller transactions and may not perform well with such high data volumes. The Composite REST API is intended for combining multiple API calls but does not cater to bulk updates effectively.
