Salesforce Sandbox is a copy of your Production org used for development and testing. Production is the live environment where real data is stored and transactions occur.
8. How do you handle governor limits in Salesforce?
Governor limits are resource usage limits in Salesforce. To handle them, optimize code, use asynchronous processing, and implement batch processing for large data sets.
9. Explain the purpose of SOQL and SOSL in Salesforce.
SOQL (Salesforce Object Query Language) is used to retrieve data from Salesforce objects. SOSL (Salesforce Object Search Language) is used to perform text searches.
10. What is the significance of the Salesforce AppExchange?

11. Describe the differences between a custom object and a standard object in Salesforce.
Standard objects are provided by Salesforce (e.g., Account, Contact), while custom objects are created by users to store specific data unique to their organization.
12. How do you secure data in Salesforce?
Data security in Salesforce is achieved through profiles, roles, permission sets, and sharing rules. Record-level security is managed using organization-wide defaults and sharing settings.
13. Explain the purpose of a Visualforce page in Salesforce.
Visualforce pages allow developers to create custom user interfaces using a combination of HTML, JavaScript, and Apex. They can be embedded within Salesforce or run as standalone web pages.

In Apex, exceptions are handled using try-catch blocks. You can catch specific exceptions and implement error handling logic.
16. Explain the difference between a role and a profile in Salesforce.
A role defines a user’s position in the hierarchy, determining access to records. A profile defines what a user can do within Salesforce, including object and field-level permissions.
