Section 1: Salesforce Fundamentals (Beginner Level)

For those starting with Salesforce, understanding the basics is key to building a strong foundation.

1. What is Salesforce?

Salesforce is a cloud-based customer relationship management (CRM) platform that provides tools to manage customer data, sales processes, and customer service. It's designed to help businesses improve their marketing, sales, and customer service efforts.

2. What are the different types of clouds in Salesforce?

Sales Cloud: Manages sales and customer relationships.
Service Cloud: Focuses on customer support and service.
Marketing Cloud: Helps manage marketing campaigns and customer journeys.
Commerce Cloud: Facilitates e-commerce solutions.
Community Cloud: Connects users with various business communities.
Analytics Cloud: Provides business intelligence and analytics.
IoT Cloud: Manages Internet of Things (IoT) data.

3. What are objects in Salesforce?

Objects are database tables that store data in Salesforce. They come in two types:
Standard Objects: Predefined by Salesforce (e.g., Account, Contact, Opportunity).
Custom Objects: Created by users to meet specific business needs.

4. What is a record in Salesforce?

A record is a single instance of an object, similar to a row in a database table. For example, an individual Account record contains information about a specific account.

Section 2: Salesforce Administration (Intermediate Level)

As a Salesforce Admin, you'll be managing user access, security, and configuring the platform to meet organizational needs.

5. What is a profile in Salesforce?

A profile defines the permissions and access rights of a user. It determines what users can see and do within Salesforce, such as record types, fields, and page layouts.

6. What is a role in Salesforce?

A role in Salesforce determines the level of visibility a user has into an organization's data. It is primarily used for record-level access, and users in higher roles have access to the records owned by users in lower roles.

7. What is the difference between a profile and a permission set?

Profile: A profile is a user’s main access control point, providing access to objects, fields, and apps.
Permission Set: Permission sets are used to grant additional permissions to users without changing their profile.

8. How does Salesforce handle data security?

Salesforce provides several layers of security:
Object-level Security: Managed through profiles to control access to objects.
Field-level Security: Controls access to specific fields.
Record-level Security: Managed using sharing rules and roles to control access to records.
Organization-level Security: Defines access to the overall Salesforce organization.

9. What are workflow rules in Salesforce?

Workflow rules automate standard internal procedures and processes. They can trigger actions like sending emails, updating fields, or creating tasks when certain conditions are met.

Section 3: Salesforce Development (Advanced Level)

If you're aiming for a Salesforce Developer role, mastering the development tools and techniques is essential.

10. What is Apex in Salesforce?

Apex is Salesforce's proprietary programming language, similar to Java, used to execute flow and transaction control statements on the Salesforce platform’s server-side.

11. What are triggers in Salesforce?

Triggers are pieces of Apex code that execute before or after a record is inserted, updated, deleted, or undeleted. They allow developers to automate actions based on changes in Salesforce data.

12. What is Visualforce in Salesforce?

Visualforce is a framework used to build custom user interfaces in Salesforce. It is often used in conjunction with Apex to create dynamic pages that interact with Salesforce data.

13. What is a Lightning Component in Salesforce?

Lightning Components are modular and reusable units of code used in the Lightning Experience interface. They offer a more dynamic and interactive user experience compared to Visualforce pages.

14. What is SOQL (Salesforce Object Query Language)?

SOQL is a query language used to retrieve data from Salesforce’s relational database. It is similar to SQL but is tailored to Salesforce's structure.

15. What is SOSL (Salesforce Object Search Language)?

SOSL is used to search for text, email, or phone number data across multiple objects in Salesforce. It’s a useful tool when you're unsure where a particular piece of information resides.

Section 4: Salesforce Architecture and Integration (Expert Level)

For experienced candidates, understanding Salesforce architecture and integration options will be crucial to solving complex challenges.

16. What is Salesforce’s multitenant architecture?

Salesforce operates on a multitenant architecture, which means that multiple customers share the same infrastructure and resources. However, each customer’s data is securely isolated.

17. What are Governor Limits in Salesforce?

Salesforce enforces governor limits to ensure that no single organization can monopolize shared resources. These limits govern how many records you can process in a transaction, how much data you can query, etc.

18. What is Salesforce’s data model?

Salesforce’s data model is based on objects and fields, much like a relational database. It allows developers to create custom objects and fields, manage relationships, and store data effectively.

19. What is the difference between a Full Sandbox and a Developer Sandbox?

Full Sandbox: A replica of your entire Salesforce production environment, including all data, configuration, and customization.
Developer Sandbox: A smaller version of the Salesforce environment used for testing and development without real data.

20. How do you integrate Salesforce with external systems?

Salesforce supports several integration options:
REST API: Allows for integration with external systems over HTTP.
SOAP API: A more traditional web service API for integration.
Outbound Messages: Send messages to external systems when specific conditions are met.
Platform Events: Used for real-time event-based integration.
Middleware Tools: Tools like MuleSoft and Jitterbit for complex integrations.

Section 5: Salesforce Advanced Features and Best Practices

These questions address the advanced features and best practices that you should be familiar with when working with Salesforce.

21. What is a Flow in Salesforce?

Flow is a powerful automation tool in Salesforce that allows you to create guided visual processes for users, as well as automate business processes.

22. What is the purpose of the AppExchange?

The AppExchange is Salesforce's marketplace where users can find and install third-party applications and components that extend Salesforce’s functionality.

23. How can you optimize performance in Salesforce?

Optimize SOQL queries: Use selective filters and avoid querying unnecessary fields.
Use indexes: Create custom indexes on frequently queried fields.
Avoid recursive triggers: Limit trigger recursion to prevent performance degradation.

24. What is a Custom Metadata Type?

Custom Metadata Types are similar to custom objects but are used to store metadata. This data is deployable and can be used to configure applications in a reusable manner.

25. What is the difference between “Before” and “After” triggers?

Before Triggers: Used for validating and modifying record values before they are saved to the database.
After Triggers: Used when you want to perform actions after the record is committed to the database (e.g., sending email notifications).
