PDI Exam Dumps - Salesforce Certified Platform Developer 1 (SP25)

B:@testSetupinserts data once and shares it across all test methods in the class, saving system resources.

D:@isTest(SeeAllData=true)is incompatible with@testSetupdue to their differing purposes for managing test data.

Advantages of Lightning Web Components (LWC):

A. Rich component ecosystem:

LWCs have a modern, rich component library designed for modular and reusable development.

D. Self-contained and reusable units:

LWCs are designed to be modular, reusable, and self-contained, reducing duplication and enhancing maintainability.

Why Not Other Options?

B. Log capturing via Debug Logs Setup page: This is unrelated to LWC and is a debugging feature.

C. Built-in standard and custom set controllers: Relevant to Visualforce, not LWCs.

A: Declarative development does not require Apex test classes since it leverages built-in Salesforce features such as flows, process builders, and validation rules.

C: Declarative development can be done using the Setup menu, which includes point-and-click tools like page layouts, workflows, and Lightning App Builder.

Why not other options?

B: Declarative development has strict limits (e.g., process builders and flows have governor limits that are lower than programmatic approaches like Apex).

D: Declarative logic still requires maintenance, especially as business needs evolve.

A try-catch block allows the batch to continue processing even if some records cause errors. Errors can be logged for review, ensuring the integration process does not stop entirely.

The deployment fails because the Apex trigger has 0% test coverage. Even though the helper class is covered, Salesforce requires at least 1% test coverage for the trigger itself. To resolve this, a test class and methods must specifically invoke the trigger by performing DML operations on the related object.

Using aforloop allows iterating through the list, and aniforif-elsecondition inside can evaluate theLastModifiedDatefor each account to determine its status.

A validation rule can ensure that theLead Sourcefield is populated before the Lead is converted. This prevents users from proceeding unless the required data is entered.

Why not other options?

A: Triggers are programmatic, whereas a declarative solution like validation rules is simpler and more efficient.

B: Lead Conversion field mapping maps fields between Lead and Account/Contact but cannot enforce field requirements.

C: A formula field is read-only and cannot enforce user input.

Before-save Apex Trigger:

This is the best solution because abefore-save triggerruns before the record is saved to the database, providing an opportunity to validate or modify the data.

In this case, the Apex trigger can validate the email address using a regular expression or a third-party API call to ensure the email address is valid. If the email is invalid, an error message can be displayed using addError().

Why not the other options?

A. Submit a REST API Callout with a JSON payload:

REST callouts are more complex and generally not recommended for simple validation tasks like email format validation. Additionally, callouts cannot be performed directly in a before-save trigger.

C. Use a custom Lightning Web Component (LWC):

LWCs are primarily for UI interactions and should not be used to enforce data validations that are server-side requirements.

D. Use an Approval Process:

Approval Processes are for managing the approval flow of records, not for real-time validations. They cannot enforce email validation directly.
