2. Salesforce Administration<\/h2>\n

Q: What is a custom object in Salesforce, and how do you create one?<\/h3>\n

A: A custom object is a database table that allows you to store company-specific information that doesn’t fit into the standard objects. To create a custom object:<\/p>\n

Go to Setup<\/li>\n
In the Object Manager, click “Create” > “Custom Object”<\/li>\n
Fill in the required fields (Label, Plural Label, Object Name)<\/li>\n
Choose the desired options (e.g., Allow Reports, Allow Activities)<\/li>\n

Click “Save”<\/li>\n<\/ol>\n

Q: Explain the difference between Workflow Rules and Process Builder.<\/h3>\n

A: Both Workflow Rules and Process Builder are automation tools in Salesforce, but they have some key differences:<\/p>\n

Complexity: Workflow Rules are simpler and easier to set up, while Process Builder offers more complex, multi-step processes<\/li>\n
Actions: Workflow Rules are limited to field updates, email alerts, tasks, and outbound messages. Process Builder can do all of these plus create records, submit for approval, and more<\/li>\n
Triggers: Workflow Rules can only trigger on record creation or update. Process Builder can also trigger when a record is deleted or when a platform event occurs<\/li>\n

Evaluation Criteria: Process Builder offers more flexibility in defining when a process should run<\/li>\n<\/ul>\n

Q: What is a roll-up summary field, and when would you use it?<\/h3>\n

A: A roll-up summary field is a field type that automatically calculates values from related child records. It’s used in master-detail relationships to display aggregate information on the parent record. Common use cases include:<\/p>\n

Summing the total amount of all related opportunities on an account<\/li>\n
Counting the number of contacts associated with an account<\/li>\n

Finding the maximum or minimum value among child records<\/li>\n<\/ul>\n

3. Salesforce Development<\/h2>\n

Q: What is Apex, and how does it differ from other programming languages?<\/h3>\n

A: Apex is Salesforce’s proprietary programming language used for customizing and extending Salesforce functionality. Key characteristics of Apex include:<\/p>\n

Strongly typed, object-oriented language<\/li>\n
Syntax similar to Java<\/li>\n
Designed to work with Salesforce data and features<\/li>\n
Includes built-in support for DML (Data Manipulation Language) operations<\/li>\n

Runs in a multi-tenant environment, so it has governor limits to ensure fair resource usage<\/li>\n<\/ul>\n

Q: Explain the concept of Governor Limits in Salesforce.<\/h3>\n

A: Governor Limits are restrictions imposed by Salesforce to ensure that resources are shared fairly in the multi-tenant environment. These limits prevent any single Apex transaction from monopolizing shared resources. Some examples of Governor Limits include:<\/p>\n

Maximum number of SOQL queries per transaction: 100<\/li>\n
Maximum number of DML statements per transaction: 150<\/li>\n
Maximum CPU time per transaction: 10,000 milliseconds<\/li>\n

Maximum heap size: 6 MB<\/li>\n<\/ul>\n

Q: What is a trigger in Salesforce, and what are the different types?<\/h3>\n

A: A trigger is Apex code that executes before or after specific data manipulation language (DML) events occur, such as insertions, updates, or deletions of Salesforce records. Types of triggers include:<\/p>\n

Before Insert<\/li>\n
After Insert<\/li>\n
Before Update<\/li>\n
After Update<\/li>\n
Before Delete<\/li>\n
After Delete<\/li>\n

After Undelete<\/li>\n<\/ul>\n

4. Apex Programming<\/h2>\n

Q: Write a simple Apex trigger that updates a custom field on the Account object when a related Opportunity is closed won.<\/h3>\n

A: Here’s an example of an Apex trigger that updates a custom field “Latest_Closed_Won_Date__c” on the Account object when a related Opportunity is closed won:<\/p>\n

trigger UpdateAccountOnOpportunityClosedWon on Opportunity (after update) {\n    Set<Id> accountIds = new Set<Id>();\n    \n    for (Opportunity opp : Trigger.new) {\n        Opportunity oldOpp = Trigger.oldMap.get(opp.Id);\n        if (opp.IsWon && !oldOpp.IsWon && opp.AccountId != null) {\n            accountIds.add(opp.AccountId);\n        }\n    }\n    \n    if (!accountIds.isEmpty()) {\n        List<Account> accountsToUpdate = new List<Account>();\n        for (Id accId : accountIds) {\n            accountsToUpdate.add(new Account(\n                Id = accId,\n                Latest_Closed_Won_Date__c = Date.today()\n            ));\n        }\n        update accountsToUpdate;\n    }\n}<\/code><\/pre>\nQ: Explain the difference between SOQL and SOSL.<\/h3>\nA: SOQL (Salesforce Object Query Language) and SOSL (Salesforce Object Search Language) are both used to retrieve data from Salesforce, but they have different purposes:<\/p>\n
\nSOQL:\n\nUsed for retrieving records from a single object or related objects<\/li>\n
Similar to SQL, but designed for Salesforce data structure<\/li>\n
Can use relationships to query related objects<\/li>\n

Examples: Web-to-Lead, Email-to-Case, REST API, SOAP API<\/li>\n
Use cases: Importing data from external sources, creating records from web forms<\/li>\n<\/ul>\n<\/li>\n<\/ul>\nQ: What are Connected Apps in Salesforce?<\/h3>\nA: Connected Apps are applications that integrate with Salesforce using APIs. They allow external applications to authenticate with Salesforce and access Salesforce data. Key aspects of Connected Apps include:<\/p>\n
\nOAuth 2.0 authentication<\/li>\n
Single Sign-On (SSO) capabilities<\/li>\n
Mobile app integration<\/li>\n
API access control<\/li>\n
Custom attributes for sharing user data<\/li>\n<\/ul>\n7. Security and Sharing<\/h2>\n
Q: Explain the difference between Profiles and Permission Sets in Salesforce.<\/h3>\nA: Profiles and Permission Sets are both used to control user access in Salesforce, but they have some key differences:<\/p>\n
\nProfiles:\n\nEvery user must have exactly one profile<\/li>\n
Provide a baseline of permissions for users<\/li>\n
Control object permissions, field-level security, and app visibility<\/li>\n
Can be used to control login hours and IP restrictions<\/li>\n<\/ul>\n<\/li>\n
Permission Sets:\n\nUsers can have multiple permission sets<\/li>\n
Used to grant additional permissions beyond what’s in a user’s profile<\/li>\n
More flexible and easier to maintain than profiles<\/li>\n
Can be assigned temporarily for specific tasks or projects<\/li>\n<\/ul>\n<\/li>\n<\/ul>\nQ: What is Role Hierarchy in Salesforce, and how does it affect record sharing?<\/h3>\nA: Role Hierarchy in Salesforce is a tree-like structure that represents the organizational hierarchy of a company. It affects record sharing in the following ways:<\/p>\n
\nUsers higher in the hierarchy can access records owned by users below them<\/li>\n
Sharing rules can be based on roles or role hierarchies<\/li>\n
It allows for automatic upward sharing of records<\/li>\n
It doesn’t automatically grant edit access; that’s controlled by sharing settings<\/li>\n<\/ul>\nQ: Describe the different types of sharing rules in Salesforce.<\/h3>\nA: Salesforce offers several types of sharing rules to control record access:<\/p>\n
\nOwner-Based Sharing Rules: Share records based on the record owner’s role, territory, or public group<\/li>\n
Criteria-Based Sharing Rules: Share records that meet specific field criteria<\/li>\n
Guest User Sharing Rules: Control record access for unauthenticated guest users in communities<\/li>\n
Manual Sharing: Allows record owners to share individual records with specific users or groups<\/li>\n
Apex Managed Sharing: Programmatically control sharing using Apex code<\/li>\n<\/ol>\n8. Scenario-Based Questions<\/h2>\n
Q: A client wants to automatically create a follow-up task whenever a high-value opportunity is closed. How would you implement this?<\/h3>\nA: To implement this requirement, you could use one of the following approaches:<\/p>\n
\nProcess Builder:\n\nCreate a new Process on the Opportunity object<\/li>\n
Set the process to trigger when a record is created or edited<\/li>\n
Add criteria to check if the opportunity is closed and meets the high-value threshold<\/li>\n
Add an action to create a new Task record with the required details<\/li>\n<\/ul>\n<\/li>\n
Apex Trigger:\n\nCreate a trigger on the Opportunity object<\/li>\n
In the trigger, check if the opportunity is being closed and meets the high-value criteria<\/li>\n
If conditions are met, create a new Task record and insert it<\/li>\n<\/ul>\n<\/li>\n<\/ol>\nQ: Your organization wants to track the total value of all closed-won opportunities for each account in the current fiscal year. How would you approach this?<\/h3>\nA: To implement this requirement, you could:<\/p>\n
\nCreate a custom field on the Account object (e.g., “Total_Closed_Won_This_FY__c”)<\/li>\n
Use a Roll-Up Summary field if the relationship between Account and Opportunity is Master-Detail<\/li>\n
If using a Lookup relationship, create an Apex trigger on the Opportunity object:\n\nTrigger should fire on insert, update, and delete of Opportunities<\/li>\n
Query all closed-won Opportunities for the related Account in the current fiscal year<\/li>\n
Sum the values and update the custom field on the Account<\/li>\n<\/ul>\n<\/li>\n
Optionally, create a scheduled Apex job to recalculate the values periodically to ensure accuracy<\/li>\n<\/ol>\nQ: A sales team wants to be notified when a lead hasn’t been contacted in 30 days. How would you implement this automation?<\/h3>\nA: To implement this automation, you could use the following approach:<\/p>\n
\nCreate a custom Date field on the Lead object to track the last contact date<\/li>\n
Use Process Builder or Flow to update this field whenever a task or event related to the lead is completed<\/li>\n
Create a scheduled Apex class that runs daily to:\n\nQuery for Leads where the last contact date is more than 30 days ago<\/li>\n
Send an email notification to the Lead owner or a specified group<\/li>\n
