Salesforce Platform Developer Practice Exam

Which statement ensures that a Salesforce application can scale effectively for multiple users?

1. Implement custom user sessions.

2. Utilize sharing settings effectively.

3. Optimize SOQL queries to retrieve maximum records.

4. Design for bulk operations within Apex.

The correct answer is: Design for bulk operations within Apex.

Designing for bulk operations within Apex is crucial for scaling a Salesforce application effectively for multiple users. When an application is designed with bulk processing in mind, it can handle large volumes of data and multiple transactions simultaneously without degrading performance. This is particularly important in a multi-tenant environment like Salesforce where resources are shared among numerous users. Apex provides specific features that enable developers to process records in bulk, such as trigger patterns that operate on collections of records instead of executing one record at a time. By using bulk processing techniques, developers can minimize resource consumption, adhere to governor limits, and provide a more responsive and efficient experience for users, regardless of the number of users accessing the application at any given time. This approach allows the application to remain performant as the number of users and transactions increases, which is essential for maintaining a smooth experience in a scalable way.
