Account Trigger:

Apex triggers allow for complex logic to retrieve and update theTimezonefield based onPostalCodeToTimezone__c.

Fast Field Updates Record-Triggered Flow:

A record-triggered flow in Fast Field Updates mode can fetch the necessary data fromPostalCodeToTimezone__cand update the Account.

Why Not Other Options?

A. Quick actions: Used for user interface updates, not for automation based on edits.

B. Approval process: Not relevant to dynamic field updates.

WhyWITH SECURITY_ENFORCED?

Ensures field-level security and sharing rules are enforced in SOQL queries.

Prevents unauthorized records or fields from being accessed or displayed.

Why Not Other Options?

B and C:with sharingandinherited sharingenforce record-level access but do not handle field-level security.

D:without sharingignores sharing rules, which would display all records regardless of user permissions.

The code snippet in question creates and inserts an account namedMyAccountand then initializes a loop to add additional accounts.

The loop runs fromx = 1and continues adding accounts untilx < 10.

Since the conditionx++is post-increment, the loop runs exactly 10 times, creating and adding 10 new accounts to thenewAccountslist.

At the end, theinsertDML statement persists these 10 new accounts, along with the already existing account (MyAccount).

Total accounts in the org:

Existing accounts = 5

New accounts added = 10

Total = 15

Salesforce Apex Developer Guide

Salesforce SOQL & SOSL Reference

The Lightning component cannot directly perform SOQL queries.

An Apex class annotated with@AuraEnabledprovides server-side logic that can execute the SOQL query and return the data to the Lightning component.

Apex AuraEnabled Methods

75% Code Coverage (A):To deploy Apex code to production, Salesforce requires at least 75% of the code to be covered by tests across the organization.

Comprehensive and Detailed Explanation From Exact Extract:

In Lightning Web Components, to cache the results of Apex methods on the client side, the Apex method should be annotated with @AuraEnabled(cacheable=true). This enables the Lightning Data Service to cache the method's response, improving performance by reducing server calls.

Advantages of Lightning Web Components (LWC):

A. Rich component ecosystem:

LWCs have a modern, rich component library designed for modular and reusable development.

D. Self-contained and reusable units:

LWCs are designed to be modular, reusable, and self-contained, reducing duplication and enhancing maintainability.

Why Not Other Options?

B. Log capturing via Debug Logs Setup page: This is unrelated to LWC and is a debugging feature.

C. Built-in standard and custom set controllers: Relevant to Visualforce, not LWCs.

To override the Account's standard Edit button in Lightning Experience, a Lightning action can be created and associated with the object. This action can include custom logic or a Lightning component.

Validation Rule Violations:

Salesforce automatically throws exceptions for validation rule violations during DML operations.

<apex:messages>is used to display these errors to the user.

Why Not Other Options?

A: Controller attributes alone cannot handle validation messages.

B: A try/catch block does not address validation rule violations effectively.

D:Database.upsert()method is not related to validation error handling.

To notify the parent component when the child component’sNextbutton is clicked, the child component can dispatch a custom event. The parent component listens to this event and handles navigation accordingly.
