Salesforce Updated PDI Exam Questions and Answers by zaviyar

Why Data Export Scheduled Job?

Salesforce provides an out-of-the-box Data Export feature that allows organizations to back up their data, including attachments.

This feature can be scheduled to run automatically on a monthly basis, fulfilling the requirement.

Why Not Other Options?

A. Schedule a Report: Does not export attachments and is limited to reportable data.

B. Data Loader Command Line: Requires manual setup and scripting, which is unnecessary for this requirement.

D. Create a Schedulable Apex class: Not suitable, as the Data Export tool is more efficient for full data and attachment backup.

In Option B, the webservice keyword is used to declare the class and the specific method updateRecords. This is correct because:

The helper method helperMethod is private and not exposed to the external application.

The webservice method updateRecords is declared global static, making it accessible externally.

When building a Lightning Web Component (LWC) to collect and manage data, developers must ensure compliance with Salesforce's security model, including field-level security (FLS) and object-level security (OLS). To meet the requirement of respecting security controls, lightning-input-field is the correct choice.

Why lightning-input-field?

Field-Level Security (FLS):lightning-input-field respects the user’s field-level security settings. This means users can only view or edit fields that they have permissions for, ensuring compliance with the organization’s security model.

Object-Level Security (OLS):It respects object-level security, ensuring users cannot access objects they are restricted from accessing.

Simplified Development:It is part of the Lightning Data Service (LDS), which eliminates the need to write custom Apex or SOQL queries for CRUD operations, reducing the potential for security gaps.

Dynamic Rendering:Since the component dynamically renders fields based on the user’s permissions, developers can share the component across various user groups without additional customization.

Declarative Syntax:lightning-input-field simplifies form creation in LWC by using declarative syntax to bind to record fields directly.

Example Code Implementation:
