8. How does Salesforce ensure data security, and what are profiles and roles used for?

   • Answer: Salesforce ensures data security through profiles and roles. Profiles control access to objects, fields, and records, while roles define who can see or edit records based on hierarchy levels.

9. Describe the role of governor limits in Salesforce.

   • Answer: Governor limits are runtime limits enforced by the Apex runtime engine to ensure efficient processing of data. They prevent resource-intensive code from monopolizing shared resources.

10. What is the significance of the Master-Detail relationship in Salesforce?

    • Answer: The Master-Detail relationship in Salesforce signifies a strong parent-child relationship between two objects. It impacts record access, deletion behavior, and the roll-up summary field.

Medium Salesforce Developer Interview Questions:

11. Explain the concept of Salesforce governor limits and give examples.

    • Answer: Salesforce governor limits are runtime limits to ensure efficient resource usage. Examples include the maximum number of SOQL queries, the total number of records retrieved, and the number of CPU seconds consumed.

12. Describe the use of the @future annotation in Apex.

    • Answer: The @future annotation in Apex designates a method to run asynchronously at a later time when Salesforce resources are available. It is commonly used for long-running processes or external callouts.

13. What is the role of the Schema Builder in Salesforce?

14. Explain the difference between a trigger and a workflow rule in Salesforce.

    • Answer: A trigger is a piece of Apex code that executes before or after a record is inserted, updated, or deleted. In contrast, a workflow rule is a declarative tool used for automated standard internal procedures to save time across the platform.

15. How can you optimize the performance of a Visualforce page in Salesforce?

    • Answer: Performance optimization for Visualforce pages includes minimizing the use of SOQL queries, using lazy loading for components, and reducing the use of complex logic in controllers.

16. Discuss the benefits of using the Salesforce Lightning Component Framework.

    • Answer: The Salesforce Lightning Component Framework provides benefits such as improved performance, reusability of components, and a responsive design for building modern user interfaces in Salesforce.

17. Explain the concept of a trigger handler in Apex.

    • Answer: A trigger handler in Apex is a design pattern used to modularize and organize trigger code. It separates trigger logic from business logic, making code more maintainable and scalable.

18. What is a Batch Apex class, and when would you use it?

    • Answer: A Batch Apex class in Salesforce is used
      

      to process large sets of data asynchronously, dividing the data into smaller batches for efficient processing. It is beneficial for scenarios where the standard governor limits for synchronous processing are exceeded.

    • 19. How does Salesforce1 enhance the mobile experience for users?
