NEW QUESTION # 172
While writing an Apex class, a developer wants to make sure that all functionality being developed is handled as specified by the requirements.
Which approach should the developer use to be sure that the Apex class is working according to specifications?
Answer: C
Explanation:
Creating test classes ensures that the Apex class works according to specifications by validating the functionality under various scenarios and edge cases. Running tests in the Developer Console provides detailed feedback on whether the class meets requirements.
Reference:Testing Apex
Incorrect Options:
A:Savepoints and rollbacks are used to manage transactions, not for validation.
B:Try/catch blocks handle exceptions but do not ensure the code adheres to specifications.
C:Execute Anonymous only tests small portions of code interactively, not comprehensive functionality.
Below is the formatted response for the provided question, adhering to the specified format and requirements.
The question falls under the Salesforce Platform and Declarative Features topic, as it involves Visualforce page components and their security implications, which is a key focus of the Salesforce Platform Developer I certification. The answer is based on official Salesforce Platform Developer I documentation, with a comprehensive explanation and references to relevant Salesforce documentation.

NEW QUESTION # 176
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?
Answer: C
Explanation:
Answer B is correct. Lightning Web Components use modern web standards with Salesforce-specific modules, decorators, base components, and Lightning Data Service integration. Parent components pass data down through public properties or public methods, while children communicate upward with custom events.
Apex methods imported from @salesforce/apex must be annotated correctly and wired methods must be cacheable. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint. For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Lightning Web Components Developer Guide, Lightning Component Reference, Aura Components Developer Guide, and Visualforce Developer Guide. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.
