Which three Considerations must the developer implement to make the method available within the Lightning web component? Choose 3 answer
A. The method must specify the (cacheable-trun) attribute
B. The method must specify the (continuation-true) attribute
C. The method must be annotaled with true Invocablemethod annolation
D. The method cannot mutate the result set retrieved from the database.
E. The method must be annotated with the AureEnabled annolation
Explanation:
- @AuraEnabled is required to expose an Apex method to Lightning Web Components (LWC). Without it, the method cannot be accessed from LWC.
- cacheable=true is necessary if the method is used with the @wire decorator in LWC, allowing efficient data retrieval and caching.
- The method cannot mutate the result set retrieved from the database because cacheable=true requires the method to be read-only, meaning it cannot modify data.
What are two benefits of using External IDs? Choose 2 answers
A. An External ID field can be used Co reference an ID from another external system.
B. An External ID can be a formula field to help create a unique key from two fields in Salesforce.
C. An External ID can be used with Salesforce Mobile to make external data visible.
D. An External ID is indexed and can improve the performance of SOQl quenes.
Explanation:
- External IDs help integrate Salesforce with external systems by allowing records to be referenced using an identifier from another system rather than the Salesforce record ID.
- External IDs are indexed, which improves query performance when searching for records using SOQL.
Which two sfdx commands can be used to add testing data to a Developer sandbox?
A. Forced: data:bulk:upsert
B. Forced: data: object :upsert
C. Forced: data: tree: upsert
D. Forced: data:async:upsert
Explanation:
force:data:bulk:upsert (A)
Bulk upserts data from a CSV file into a Developer sandbox.
Ideal for large datasets (uses Bulk API for efficiency).
force:data:tree:import (C)
Imports hierarchical data (e.g., parent-child records) from a JSON file.
Maintains relationships between records during insertion.
Universal Container(UC) wants to lower its shipping cost while making the shipping process more efficient. The Distribution Officer advises UC to implement global addresses to allow multiple Accounts to share a default pickup address. The Developer is tasked to create the supporting object and relationship for this business requirement and uses the Setup Menu to create a custom object called "Global Address". Which field should the developer ad to create the most efficient model that supports the business need?
A. Add a Master-Detail field on the Account object to the Global Address object
B. Add a Master-Detail field on the Global Address object to the Account object.
C. Add a Lookup field on the Account object to the Global Address object.
D. Add a Lookup field on the Global Address object to the Account object
Explanation:
- A Lookup relationship is the best choice when multiple Accounts need to reference a single Global Address.
- This allows many Accounts to share the same default pickup address, ensuring efficiency in shipping operations.
- A Master-Detail relationship would not be ideal because it enforces strict ownership and deletion dependencies, which are unnecessary for this use case.
- The Lookup field should be placed on the Account object, linking it to the Global Address object, so each Account can reference a shared address.
A developer has a Visualforce page and custom controller to save Account records. The developer wants to display any validation rule violation to the user. How can the developer make sure that validation rule violations are displayed?
A. Add cuatom controller attributes to display the message.
B. Include
C. Use a try/catch with a custom exception class.
D. Perform the DML using the Database.upsert() method.
Explanation:
- When using a custom controller, validation rule errors do not automatically display like they do with standard controllers.
- To ensure validation errors appear on the Visualforce page, the developer should use Database.upsert() instead of DML operations like insert or update.
- The Database.upsert() method returns a Database.SaveResult object, which allows the developer to capture errors and display them using ApexPages.addMessages().
Universal Containers wants to ensure that all new leads created in the system have a valid email address. They have already created a validation rule to enforce this requirement, but want to add an additional layer of validation using automation. What would be the best solution for this requirement?
A. Submit a REST API Callojt with a JSON payload and validate the f elds on a third patty system
B. Use an Approval Process to enforce tne completion of a valid email address using an outbound message action.
C. Use a before-save Apex trigger on the Lead object to validate the email address and display an error message If it Is invalid
D. Use a custom Lightning web component to make a callout to validate the fields on a third party system.
Explanation:
- A before-save Apex trigger is the most efficient way to enforce additional validation beyond standard validation rules.
- It allows the developer to check the email format using regular expressions or other logic before the record is committed to the database.
- If the email is invalid, the trigger can prevent the record from being saved and display an error message to the user.
trigger LeadTrigger on Lead (before insert, before update) {
for (Lead l : Trigger.new) {
if (l.Email != null && !Pattern.matches('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,}$',
l.Email.toUpperCase())) {
l.Email.addError('Please enter a valid email address.');
}
}
}
Which Lightning code segment should be written to declare dependencies on a Lightning component, c:accountList, that is used in a Visualforce page?
A. Option A
B. Option B
C. Option C
D. Option D
Explanation:
Purpose: To use a Lightning component (c:accountList) in a Visualforce page, you must declare it in a Lightning Out dependency app.
Key Requirements:
extends="ltng:outApp": Required to enable Lightning components in Visualforce.
access="GLOBAL": Ensures the app is accessible to Visualforce.
Cloud kicks has a multi-screen flow that its call center agents use when handling inbound service desk calls. At one of the steps in the flow, the agents should be presented with a list of order numbers and dates that are retrieved from an external order management system in real time and displayed on the screen. What should a developer use to satisfy this requirement?
A. An Apex controller
B. An Apex REST class
C. An outbound message
D. An invocable method
Explanation:
- Since the order numbers and dates need to be retrieved in real time from an external system, an Apex REST class is the best approach.
- Apex REST classes allow Salesforce to make callouts to external APIs, fetching data dynamically when needed.
- The retrieved data can then be displayed in the multi-screen flow, ensuring agents see the most up-to-date information.
If apex code executes inside the execute() method of an Apex class when implementing the Batchable interface, which statement are true regarding governor limits? Choose 2 answers
A. The Apex governor limits might be higher due to the asynchronous nature of the transaction.
B. The apex governor limits are reset for each iteration of the execute() method.
C. The Apex governor limits are relaxed while calling the constructor of the Apex class.
D. The Apex governor limits cannot be exceeded due to the asynchronous nature of the transaction,
Explanation:
- A. Higher governor limits for asynchronous transactions: Batch Apex runs asynchronously, and Salesforce provides higher governor limits for asynchronous processes compared to synchronous ones. For example, the number of SOQL queries allowed is 200 instead of 100, and the heap size limit is 12 MB instead of 6 MB.
- B. Governor limits reset per batch execution: Each batch execution starts with a fresh set of governor limits, meaning that limits like SOQL queries, DML statements, and CPU time are reset for each batch iteration.
A developer created these three Rollup Summary fields in the custom object, Project_ct,
The developer is asked to create a new field that shows the ratio between rejected and approved timesheets for a given project.
Which should the developer use to Implement the business requirement in order to minimize maintenance overhead?
A. Record-triggered Flow
B. Formula field
C. Apex Trigger
D. Process Builder
Explanation:
Minimal Maintenance Overhead:
A formula field dynamically calculates the ratio using existing fields
(Total_Rejected_Timesheets__c / Total_Approved_Timesheets__c).
No code or automation is needed—it updates in real-time whenever the referenced fields change.
Implementation Example:
plaintext
IF(Total_Approved_Timesheets__c > 0,
Total_Rejected_Timesheets__c / Total_Approved_Timesheets__c,
NULL
)
Handles division by zero and requires zero maintenance.
A developer must create a DrawList class that provides capabilities defined in the Sortable and Drawable interfaces. public interface Sortable { void sort(); } public interface Drawable { void draw(); } Which is the correct implementation?
A. Public class DrawList implements Sortable, Implements Drawable { public void sort() { /*implementation*/} public void draw() { /*implementation*/} ]
B. Public class DrawList extends Sortable, Drawable { public void sort() { /*implementation*/} public void draw() { /*implementation*/} }
C. Public class DrawList implements Sortable, Drawable { public void sort() { /*implementation*/} public void draw() { /*implementation*/} }
D. Public class DrawList extends Sortable, extends Sortable, extends Drawable { public void sort() { /*implementation*/ } public void draw() { /* implementation */}
Explanation:
Correct Syntax for Interface Implementation:
In Java (and Apex), a class implements interfaces (not extends).
Multiple interfaces are separated by commas:
java
public class DrawList implements Sortable, Drawable {
public void sort() { /*implementation*/ }
public void draw() { /*implementation*/ }
}
Why Not the Other Options?
Option Issue
A. implements Sortable, Implements Drawable Invalid syntax (duplicate implements keyword).
B. extends Sortable, Drawable Interfaces cannot be extended by a class.
D. extends Sortable, extends Drawable Invalid syntax (repeated extends).
Key Takeaways:
✅ implements is used for interfaces.
✅ Multiple interfaces are listed once, separated by commas.
🚫 extends is only for class inheritance (not interfaces).
Universal Containers needs to create a custom user interface component that allows users to enter information about their accounts. The component should be able to validate the user input before saving the information to the database. What is the best technology to create this component?
A. Flow
B. Lightning Web Components
C. Visualforce
D. VUE JavaScript framework
Explanation:
Modern & Native Integration:
LWC is Salesforce’s recommended framework for custom UI development, offering seamless integration with Salesforce data and security models.
Built for performance and scalability, leveraging modern web standards (Web Components).
Real-Time Validation:
Supports client-side validation (JavaScript) before saving data to the database.
Example: Validate email formats or required fields instantly without server calls.
Database Interaction:
Uses Apex methods (with @AuraEnabled) or Lightning Data Service to securely save data.
❌ Why the other options are not ideal:
A. Flow
❌ Flows are great for process automation and guided screens, but are limited in UI customization and flexibility.
They don’t offer the same level of control over validation and UI behavior as LWC.
C. Visualforce
❌ Outdated compared to LWC.
Limited to page-based architecture, and not optimized for modern, dynamic UI.
Best used for legacy components or where Visualforce-specific features are needed.
D. Vue.js (VUE JavaScript framework)
❌ Not a Salesforce-supported framework.
While powerful for standalone web apps, using it with Salesforce requires external hosting,
integrations, and security management.
Not recommended for internal Salesforce UIs.
