Qns : Intoduction
Qns: 1 Can We Restrict Access Using Permission Set?
Answer 1: Yes, permission sets are primarily used to grant additional access, not restrict it. To restrict access, you would use profiles, sharing rules, or field-level security, as permissions in Salesforce are additive in nature.
Qns: When Did You Last Use Permission Sets and for What Purpose?
Answer 2: The last use of permission sets was to provide specific users access to a new custom object in Salesforce without altering their existing profiles. This ensured the security model remained intact while providing flexibility in access control.
Qns: What is Muting for Permission Sets?
Answer 3: Muting permission sets is a feature in Permission Set Groups that allows administrators to disable certain permissions within the group, offering fine-grained control over permissions without needing to recreate or modify individual permission sets.
Qns: Worked on CRM Dashboards?
Answer 4: Yes, I have worked on CRM dashboards to provide actionable insights into key metrics like sales performance, pipeline status, and customer trends by integrating custom reports and real-time data visualization.
Qns: How Can We Retrieve CRM Dashboards?
Answer 5: CRM dashboards can be retrieved using Metadata API, Workbench, or Salesforce CLI. Example:
bashCopy codesfdx force:source:retrieve -m Dashboard:Dashboard_Name
Qns: What Are the Ways in LWC for Child-to-Parent and Parent-to-Child Communications?

Qns: Tell Me Some Differences Between Aura & LWC
Answer 8:
| Aspect | Aura | LWC |
|---|---|---|
| Framework | Built on Aura Framework | Uses Web Standards (HTML/JS) |
| Performance | Slower, uses Shadow DOM | Faster, uses Native DOM |
| Reusability | Less reusable components | Highly reusable components |
Qns: What Can We Do With Aura and Not in LWC?
Answer 9: Aura supports two-way data binding and enables features like LockerService, which is stricter compared to LWC. It also supports dynamic component creation, which LWC does not natively allow.
Qns: When Does Wire Method Get Called in LWC Lifecycle?
Answer 10: The wire method is invoked when:
- The component is loaded.
- Any reactive property specified in the wire adapter changes.
Qns: Why Do We Use Get and Set in LWC?
Answer 11: Getters (get) and setters (set) are used for:
- Calculating values dynamically for templates.
- Tracking changes to a property and executing logic when the value changes.
Qns: What is String Mutation in LWC?
Answer 12: String mutation refers to dynamically changing string values, often tracked for reactive rendering. Example: Appending text to a variable and updating the DOM in real-time.
Qns: What Are the Advantages of Using Wire Method?
Answer 13:
- Declarative and reactive data fetching.
- Automatic updates when the data source changes.
- Improved performance by leveraging cache where applicable.
Qns: How Does the Wire Method Detect Data Changes?
Answer 14: The wire method listens to changes in the underlying data source or updates to any reactive properties used in the method.
Qns: Open Notepad and Write Code for Showing Related Contacts and Opportunity of Account Object
Answer 15:
Approach: Use getRelatedListRecords wire adapter in LWC.
import { LightningElement, wire } from 'lwc';
import { getRelatedListRecords } from 'lightning/uiRelatedListApi';
export default class RelatedContactsOpportunities extends LightningElement {
contacts = [];
opportunities = [];
@wire(getRelatedListRecords, {
parentRecordId: '001XXXXXXXXXXXXXXX', // Replace with Account Id
relatedListId: 'Contacts',
fields: ['Contact.Name', 'Contact.Email']
})
wiredContacts({ data }) {
if (data) {
this.contacts = data.records;
}
}
@wire(getRelatedListRecords, {
parentRecordId: '001XXXXXXXXXXXXXXX',
relatedListId: 'Opportunities',
fields: ['Opportunity.Name', 'Opportunity.Amount']
})
wiredOpportunities({ data }) {
if (data) {
this.opportunities = data.records;
}
}
}
Qns: How Can I Display N Number of Records Without Pagination?
Answer 16: Use an infinite scroll with a load more button or event to fetch more data dynamically and append it to the list.
Qns: Can We Control Field Label Security in Apex? How?
Answer 17: No, field label security cannot be controlled in Apex. However, you can enforce field-level access using the stripInaccessible method to filter out fields the user does not have access to.
Qns: What Are Wrapper Classes? Can You Write Sample Code?
Answer 18: A wrapper class is a custom data structure that groups related objects or data for easier handling in Apex.
Sample Code:
public class AccountWrapper {
public Account acc { get; set; }
public Boolean isSelected { get; set; }
public AccountWrapper(Account a, Boolean selected) {
this.acc = a;
this.isSelected = selected;
}
}

meeting.Status__c = 'Cancelled';
