NEW QUESTION # 166
While developing an Apex class with custom search functionality that will be launched from a Lightning Web Component, how can the developer ensure only records accessible to the currently logged in user are displayed?

  • A. Use the inherited sharing keyword.
  • B. Use the without sharing keyword.
  • C. Use the WITH SECURITY_ENFORCED clause within the SOQL.
  • D. Use the with sharing keyword.

Answer: D

Explanation:
To ensure that only records accessible to the currently logged-in user are displayed when developing an Apex class for custom search functionality launched from a Lightning Web Component (LWC), the developer should use the with sharing keyword.
with sharing Keyword: This keyword enforces the sharing rules of the current user, ensuring that the Apex class respects the user's record-level access permissions. When an Apex class is declared with with sharing, it enforces sharing rules, meaning users can only access records they have permission to see.
"Use the with sharing keyword when declaring a class to enforce the sharing rules that apply to the current user."
- Apex Developer Guide: Using the with sharing or without sharing Keywords Importance in LWCs: Lightning Web Components invoke Apex methods annotated with @AuraEnabled, which execute in system context by default. Without specifying sharing, these methods can access all records, potentially exposing data that the user shouldn't see.
"By default, Apex code runs in system context; that is, the current user's permissions and field-level security do not apply."
- Apex Developer Guide: Enforcing Sharing Rules
Why Not inherited sharing: While inherited sharing allows an Apex class to run in the sharing context of the caller, in this scenario, since the LWC does not have an inherent sharing context, using with sharing explicitly ensures sharing rules are enforced.
WITH SECURITY_ENFORCED Clause: This SOQL clause enforces field-level security (FLS) and object-level security (OLS), not record-level sharing rules. Therefore, it does not restrict records based on the user's sharing settings.
"The WITH SECURITY_ENFORCED clause applies object-level and field-level security checks to SOQL queries to ensure that users don't see fields or objects they don't have access to."
- SOQL and SOSL Reference: WITH SECURITY_ENFORCED Clause
Conclusion: By declaring the Apex class with with sharing, the developer ensures that only records the user has access to are returned, aligning with the requirement.


NEW QUESTION # 167
A Visual Flow uses an apex Action to provide additional information about multiple Contacts, stored in a custom class, contactInfo. Which is the correct definition of the Apex method that gets additional information?

  • A. @InvocableMethod(label='additional Info')
    public static ContactInfo getInfo(Id contactId)
    { /*implementation*/ }
  • B. @InvocableMethod(label='Additional Info')
    public List<ContactInfo> getInfo(List<Id> contactIds)
    { /*implementation*/ }
  • C. @InvocableMethod(Label='additional Info')
    public ContactInfo(Id contactId)
    { /*implementation*/ }
  • D. @invocableMethod(label)='Additional Info')
    public static List<ContactInfo> getInfo(List<Id> contactIds)
    { /*Implementation*/ }

Answer: D


NEW QUESTION # 168
A custom object Trainer_ < has a lookup field to another custom object cym__ c.
Which SOQL query will get the record for the Viridian City Gym and all it's trainers?

  • A. SELECT ID FROM Trainer ¢ WHERE Gym__r.Name = 'Viridian City Gym'
  • B. SELECT Id, (SELECT Id FROM Trainers_c) FROM Gym_c WHERE Name - 'Viridian City Gym''
  • C. SELECT Id; (SELECT Id FROM Trainers_r) FROM Gym_ _c WHERE Name = 'Viridian City Gym'
  • D. SELECT Id, (SELECT Id FROM Trainer_c) FROM Gym__c WHERE Name = 'Viridian City Gym'

Answer: C

Explanation:
Given that Trainer__c has a lookup field to Gym__c, to retrieve the record for the 'Viridian City Gym' and all its trainers, the correct SOQL query is:
Option A:
SELECT Id, (SELECT Id FROM Trainers__r) FROM Gym__c WHERE Name = 'Viridian City Gym' Parent-to-Child Query (Subquery):
To retrieve child records (trainers) from the parent record (gym), you perform a subquery using the child relationship name.
Child Relationship Name:
For a lookup relationship, the child relationship name can be found in the relationship settings.
By default, if the lookup field on Trainer__c is Gym__c, the child relationship name is Trainers__r.
Query Breakdown:
SELECT Id, (SELECT Id FROM Trainers__r) FROM Gym__c WHERE Name = 'Viridian City Gym' Selects the Gym record and all related Trainers.
Why Other Options Are Incorrect:
Option B: (SELECT Id FROM Trainer__c)
Trainer__c is an object, not a relationship name, so the subquery is incorrect.
Option C: SELECT ID FROM Trainer__c WHERE Gym__r.Name = 'Viridian City Gym' This query retrieves Trainer records, not the Gym record and its trainers as specified.
Option D: (SELECT Id FROM Trainers__c)
Trainers__c is incorrect; the child relationship name should end with __r in subqueries.
Reference:
SOQL Relationships and Subqueries:
"To retrieve related child records, use a subquery in the SELECT clause."
- Salesforce SOQL and SOSL Reference: Relationship Queries
Conclusion:
Option A correctly retrieves the Gym record and all its related Trainer records using a parent-to-child subquery.

What should the developer use to enforce sharing permissions for the currently logged in user while using the custom search tool?

  • A. Use the schema describe calls to determine if the logged-in user has access to the Account object.
  • B. Use the userInfo Apex class to filter all SOQL queries to returned records owned by the logged-in user.
  • C. Use the without sharing keyword on the class declaration.
