Exam PDII Topic 1 Question 154 Discussion

The three changes that the developer should implement in the Apex class to ensure the LWC can display data efficiently while preserving security are to annotate the Apex method with @AuraEnabled, implement the with sharing keyword in the class declaration, and annotate the Apex method with @AuraEnabled(Cacheable=True). The @AuraEnabled annotation allows the Apex method to be called from a Lightning web component, and exposes the method to the Lightning Data Service. The with sharing keyword enforces the sharing rules and permissions of the current user when accessing the records, and ensures that the data is secure and compliant. The @AuraEnabled(Cacheable=True) annotation enables the Apex method to be cached by the Lightning Data Service, and improves the performance and efficiency of the data retrieval. Implement the without keyword in the class declaration is not a valid answer, as it ignores the sharing rules and permissions of the current user when accessing the records, and compromises the data security and compliance. Use the WHERE clause within the SOQL query is not a valid answer, as it is not a change in the Apex class, and it does not affect the security or efficiency of the data display.
