質問 # 123
A developer created a child Lightning web component nested inside a parent Lightning web component. The parent component needs to pass a string value to the child component.
In which two ways can this be accomplished?
Choose 2 answers
正解：A、B
解説：
In Lightning Web Components (LWC), communication between parent and child components can be achieved in several ways.
Option A: The parent component can use a public property to pass the data to the child component.
Correct Method.
The child component can declare a public property using the @api decorator.
The parent component can then pass data to the child component via this property in the template.
Example:
Child Component (childComponent.js):
import { LightningElement, api } from 'lwc';
export default class ChildComponent extends LightningElement {
@api
myProperty;
}
Parent Component Template (parentComponent.html):
<template>
<c-child-component my-property={parentValue}></c-child-component>
</template>
The child component can expose a public method using the @api decorator.
The parent can call this method using a DOM query selector.
Example:
Child Component (childComponent.js):
import { LightningElement, api } from 'lwc';
export default class ChildComponent extends LightningElement {
@api
myMethod(value) {
// handle the value
}
}
Parent Component (parentComponent.js):
import { LightningElement } from 'lwc';
export default class ParentComponent extends LightningElement {
handleButtonClick() {
const childComponent = this.template.querySelector('c-child-component'); childComponent.myMethod('some value');
}
}
Custom events in LWC are used for child-to-parent communication.
The child component can dispatch events to communicate with the parent.
Events do not flow from parent to child in LWC.
Using an Apex controller to pass data between parent and child components is unnecessary and inefficient.
Apex controllers are used for server-side data operations, not component communication.
Reference:
Passing Data to Child Components
Option B: The parent component can invoke a public method in the child component.
Correct Method.
Calling Methods on Child Components
Options Not Suitable:
Option C: The parent component can use a custom event to pass the data to the child component.
Incorrect for Parent-to-Child Communication.
Communicating with Events
Option D: The parent component can use the Apex controller class to send data to the child component.
Not Appropriate.
Calling Apex Methods
Conclusion:
The parent component can pass a string value to the child component using Option A (public property) and Option B (public method).
These are the standard and recommended ways for parent-to-child communication in LWC.
質問 # 124
Which annotation should a developer use on an Apex method to make it available to be wired to a property in a Lightning web component?
正解：D
解説：
Answer A A is correct. Lightning Web Components use modern web standards with Salesforce-specific modules, decorators, base components, and Lightning Data Service integration. Parent components pass data down through public properties or public methods, while children communicate upward with custom events.
Apex methods imported from @salesforce/apex must be annotated correctly and wired methods must be cacheable. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint. For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Lightning Web Components Developer Guide, Lightning Component Reference, Aura Components Developer Guide, and Visualforce Developer Guide. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.
質問 # 125
A developer must create a Lightning component that allows users to input Contact record information to create a Contact record, including a Salary c custom field.
What should the developer use, along with a lightning-record-edit-form, so that Salary__c field functions as a currency input and is only viewable and editable by users that have the correct field level permissions on Salary _c?
正解：B
解説：
* The requirement specifies that the Salary__c field should function as a currency input and honor field- level security.
* The lightning-input-field component (Option C) automatically respects field-level permissions set in Salesforce and ensures the Salary__c field is editable and viewable only by authorized users.
* Other options do not guarantee compliance with field-level security:
* Option A: <lightning-input-currency> does not enforce field-level security.
* Option B: <lightning-formatted-number> is read-only and cannot be used for editing.
* Option D: <lightning-input> requires custom logic for enforcing security.

* Lightning Web Components Documentation
* Field-Level Security Best Practices
質問 # 126
When a user edits the Postal Code on an Account, a custom Account text field named "Timezone" must be updated based on the values in a PostalCodeToTimezone__c custom object.
Which two automation tools can be used to implement this feature? Choose 2 answers
正解：A、C
解説：
* Account Trigger:
* Apex triggers allow for complex logic to retrieve and update the Timezone field based on PostalCodeToTimezone__c.
* Fast Field Updates Record-Triggered Flow:
* A record-triggered flow in Fast Field Updates mode can fetch the necessary data from PostalCodeToTimezone__c and 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.
* Record-Triggered Flow: https://help.salesforce.com/s/articleView?id=sf.flow_build_trigger.htm References:
