NEW QUESTION # 127
When would a developer use a custom controller instead of a controller extension? Choose 2 answers:
Answer: A,C
NEW QUESTION # 128
A custom object Trainer_c has a lookup field to another custom object Gym_c. Which SOQL query will get the record for the Viridian City Gym and all its trainers?
Answer: D
Explanation:
Answer B is correct. To query a parent Gym__c record and include all related Trainer__c child records, SOQL uses a parent-to-child subquery. The subquery must use the child relationship name, which for a custom lookup normally ends in __r and is often pluralized or explicitly configured, such as Trainers__r. The source option represents that intended child relationship form. Option D is incorrect because it uses the object API name Trainer__c inside the subquery; parent-to-child subqueries do not use the child object name there.
Option C is a child-to-parent query and would return Trainer records rather than one Gym record containing its trainers. Option A has the same relationship-name problem as option D. The verified SOQL pattern is SELECT Id, (SELECT Id FROM ChildRelationshipName__r) FROM Parent__c WHERE Name = ' ... ' .
Reference focus: SOQL relationship queries in the Salesforce SOQL and SOSL Reference. This matters on the Salesforce platform because the same logic can run from the user interface, API operations, imports, and background automation.

NEW QUESTION # 130
A developer is migrating a Visualforce page into a Lightning web component.
Salesforce Certified Platform Developer I
The Visualforce page shows information about a single record. The developer decides to use Lightning Data Service to access record data.
Which security consideration should the developer be aware of?
Answer: C
Explanation:
When using Lightning Data Service (LDS) in a Lightning Web Component (LWC), it's important to understand how data security is handled.
Option D: Lightning Data Service handles sharing rules and field-level security.
Correct Statement.
Lightning Data Service enforces all the security and sharing rules that are in place in the Salesforce org.
This includes object-level, field-level, and record-level security.
When a component uses LDS to access data, the framework ensures that the user only sees data they have access to.
Benefits:
Simplifies development by abstracting security checks.
Ensures compliance with organizational security policies.
The isAccessible(), isCreateable(), and similar methods are used in Apex to check field-level security.
In LWC, when using LDS, these checks are handled automatically.
LDS enforces field-level security; it does not ignore it.
Users cannot see fields they do not have access to.
Option C: The with sharing keyword must be used to enforce sharing rules.
Not Applicable in LWC.
The with sharing keyword is used in Apex classes to enforce sharing rules.
It is not used in JavaScript code or LWC components.
Reference:
Lightning Data Service Considerations
Access Data with Lightning Data Service
Options Not Accurate:
Option A: The isAccessible() method must be used for field-level access checks.
Incorrect in LWC Context.
Security in Apex
Option B: Lightning Data Service ignores field-level security.
Incorrect.
Apex Sharing
Conclusion:
When using Lightning Data Service in LWC, developers should be aware that LDS automatically enforces sharing rules and field-level security.
This ensures that users only access data they are authorized to view.
