NEW QUESTION # 56
Refer to the following code snippet:
Java
public class LeadController {
public static List<Lead> getFetchLeadList(String searchTerm, Decimal aRevenue) { String safeTerm = '%'+searchTerm.escapeSingleQuotes()+ '%'; return [ SELECT Name, Company, AnnualRevenue FROM Lead WHERE AnnualRevenue >= :aRevenue AND Company LIKE :safeTerm LIMIT 20
];
}
}
A developer created a JavaScript function as part of a Lightning web component (LWC) that surfaces information about Leads by wire calling getFetchLeadList when certain criteria are met. Which three changes should the developer implement in the Apex class above to ensure the LWC can display data efficiently while preserving security?1
Answer: B,D,E
Explanation:
Compreh17ensive and Detailed 11850 to 250 words of Explanation:
To make an Apex method compatible with a Lightning Web Component's @wire service and ensure it follows security best practices, three specific modifications are required:
* @AuraEnabled(Cacheable=true) (Option C): The @wire service in LWC requires the Apex method to be marked as cacheable. This enables client-side caching via the Lightning Data Service, which significantly improves UI performance by reducing redundant server calls. Note that Cacheable=true is mandatory for @wire but optional for imperative calls.
* with sharing (Option B): In Apex, classes do not enforce sharing rules by default. To ensure the user only sees Leads they have access to according to the organization-wide defaults and sharing model, the class must explicitly use the with sharing keyword.
* WITH SECURITY_ENFORCED (Option A): While with sharing handles record-level access, it does not automatically enforce field-level security (FLS) or object-level security (CRUD). Adding the WITH SECURITY_ENFORCED clause to the SOQL query ensures that if a user does not have permission to view the AnnualRevenue field, the query will throw an exception rather than exposing protected data.
Options D and E are incorrect because without sharing bypasses security, and a simple @AuraEnabled without cacheable=true is insufficient for the LWC @wire service.
NEW QUESTION # 57
An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature.
The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters.
What is the optimal way to implement these requirements?
Answer: D
Explanation:
A single trigger on Contact that handles both after update and before update events, utilizing helper classes for each logic set, is the most optimal implementation. It centralizes the logic for maintaining primary contacts and normalizing last names while allowing for clear separation of concerns through helper classes.

NEW QUESTION # 58
Universal Containers implements a private sharing model for the Convention_Attendence_c custom object. As part of a new quality assurance effort, the company created an Event___Reviewer__c user lookup field on the object. Management wants the event reviewer to automatically gain Read/write access to every record they are assigned to.
What is the best approach to ensure the assigned reviewer obtains Read/Write access to the record?
Answer: A
NEW QUESTION # 59
Universal Charities (UC) uses Salesforce to collect electronic donations in the form of credit card deductions from individuals and corporations.
When a customer service agent enters the credit card information, it must be sent to 8 3rd-party payment processor for the donation to be processed, UC uses one payment processor for individuals and a different one for corporations.
What should a developer use to store the payment processor settings for the different payment processors, so that their system administrator can modify the settings once they are deployed, if needed?
Answer: A
Explanation:
Custom metadata types are ideal for storing payment processor settings that need to be changed by an administrator post-deployment. They can be deployed with managed packages and are upgradeable. Unlike Custom Objects, Custom Metadata Types also support a deployment with active data and can have their records retrieved via SOQL in Apex.References: Salesforce Help - Custom Metadata Types Overview
