Salesforce PDI Exam Made Easy: Step-by-Step Preparation Guide

Executing Anonymous Apex code is useful for running ad-hoc operations or administrative tasks in Salesforce.

Option A: To run a batch Apex class to update all Contacts

Valid Use Case.

Explanation:

Anonymous Apex can be used to initiate a batch Apex job.

The developer can write code in the Execute Anonymous window to instantiate and execute the batch class.

Example:

Database.executeBatch(new UpdateContactsBatchClass());

In an Aura component, JavaScript functions can be included in the following resources:

Controller (.js file):

Handles events triggered by user interaction or component lifecycle.

Contains action handlers defined in the component's markup.

"A client-side controller contains the handler functions that are called in response to events fired by the component or other components."— Aura Components Developer Guide: Client-Side Controller

Helper (.js file):

Contains reusable functions that can be called from the controller or renderer.

Helps to keep the controller lean by abstracting complex logic.

"A helper JavaScript resource can be added to an Aura component bundle and is used to store helper functions that can be reused in the component's client-side code."— Aura Components Developer Guide: Helper Functions

Renderer (.js file):

Allows for custom rendering behavior.

Contains methods that can override default rendering lifecycle events.

"A renderer component bundle resource allows you to customize the rendering behavior of a component."— Aura Components Developer Guide: Custom Renderers

Why Other Options Are Incorrect:

C. Style:

The .css file in an Aura component is used for styling and cannot contain JavaScript functions.

"An Aura component or application can have a style (CSS) resource to define its styles."— Aura Components Developer Guide: Style

E. Design:

The .design file is used to define metadata values for the component, especially when used in Lightning App Builder or Community Builder.

"A design resource describes the design-time behavior of an Aura component—information that visual tools need to display the component in a page or app."— Aura Components Developer Guide: Design Files

Conclusion: JavaScript functions in an Aura component can be placed in the Controller, Helper, and Renderer resources. Therefore, the correct answers are A, B, and D.

When designing a new application on the Salesforce platform that needs to support multiple tenants effectively (i.e., multiple customers or users), the developer should consider the Model-View-Controller (MVC) framework.

Option B: Model-View-Controller (MVC)

Correct Design Framework.

Explanation:

MVC is a software architectural pattern for implementing user interfaces.

Model: Represents the data and business logic.

View: Represents the presentation layer.

Controller: Handles user input and interactions.

Salesforce's platform follows the MVC pattern, which helps in separating concerns, ensuring scalability, and maintainability.

Change Sets are a point-and-click tool for migrating metadata between related Salesforce orgs, such as from a sandbox to a production org.

Option C: Deployment is done in a one-way, single transaction.

Correct.

Explanation:

Change sets are deployed in a one-way direction from the source org to the destination org.

The deployment occurs in a single transaction. If any component fails to deploy, the entire deployment is rolled back.

Option A: After-save record-triggered flow

True.

An after-save record-triggered flow can update records after they are saved.

If the flow updates a record that the trigger is listening to, it can cause the trigger to fire again, affecting the number of times it executes.

Option A: Data Import Wizard does not support Opportunities.

Explanation: The Data Import Wizard supports importing data for certain standard objects (Accounts, Contacts, Leads, Solutions, Campaign Members, and Person Accounts) and custom objects. It does not support importing data into all standard objects like Opportunities.

Defining the Order Number field as an External ID and marking it as Unique ensures:

External ID:

Allows the field to be used for matching during data import.

Helps in upsert operations.

Unique:

Ensures no duplicate Order Numbers exist.

Maintains data integrity.

Why Not Other Options:

Option A: Direct Lookup is not a valid field type for this scenario.

Option B: Lookup fields create relationships, not suitable here.

Option D: Indirect Lookup is used with external objects.

References:

External IDs:

"An external ID is a custom field that has the External ID attribute, meaning that it contains unique record identifiers from a system outside of Salesforce."— Salesforce Help: External ID Fields

The recommended process for deploying code and configurations from a Sandbox to Production is to use a change set.

Option C: Use a change set to deploy the Apex code and Lightning Components.

Explanation: Change sets are the standard mechanism provided by Salesforce for deploying customizations between connected orgs (e.g., Sandbox to Production). They support deploying Apex classes, Lightning components, and configurations.
