Free Salesforce DEX-403 Exam Actual Questions

Note: Premium Questions for DEX-403 were last updated On Feb. 04, 2025 (see below)

Question #1

What is one limitation of using schema builder when creating a field?

Reveal Solution Hide Solution
Correct Answer: C

One of the limitations when using the Schema Builder for creating fields is:

C . Cannot add fields to page layouts. While Schema Builder allows for easy visualization and creation of fields and objects, it does not support placing these fields onto specific page layouts directly from the Schema Builder interface.

To place fields on page layouts, you need to:

Navigate to Setup Object Manager select your object.

Click on Page Layouts, choose the appropriate layout, and manually add the newly created fields.

This step is necessary to ensure fields are visible and properly arranged on user interfaces.

For more details, Salesforce's Schema Builder documentation outlines its capabilities and limitations.


Question #2

Universal Containers (UC) requires that all users specify a contract is sent on each Opportunity prior to marking it as "Closed Won". UC wants to be able to report on how many Opportunities have sent Contracts compared to how many have a missing contract when the Opportunities closed.

Which field type should an app builder configure to fulfill this requirement?

Reveal Solution Hide Solution
Correct Answer: D

For tracking whether contracts have been sent for Opportunities:

D . Checkbox. This field type allows users to clearly indicate (Yes/No) whether a contract has been sent. This binary nature of checkboxes makes it simple to filter and report on Opportunities based on whether a contract was sent.

Steps to configure this field:

Navigate to Setup Object Manager Opportunity.

Click Fields & Relationships New Checkbox.

Define the field with a label (e.g., Contract Sent).

Set the default value to false (unchecked).

Add the field to the relevant page layouts.

This setup facilitates accurate reporting and ensures that opportunities cannot be marked as 'Closed Won' without indicating whether a contract was sent.

For guidance on creating fields, see Salesforce's documentation on Custom Field Creation.


Question #3

A sales manager has noticed that reps continue to input contacts directly in

their phone instead of adding them to Salesforce.

What should an app builder recommend to ensure the data makes it into Salesforce?

Reveal Solution Hide Solution
Correct Answer: C

To ensure sales reps input contacts into Salesforce rather than their personal devices:

C . Enable offline create, edit, and delete in Salesforce for Android and iOS. This feature allows sales reps to enter contact information directly into the Salesforce Mobile App even when they are offline, which syncs back to Salesforce once connectivity is restored.

Steps to enable offline capabilities:

Navigate to Setup Mobile Administration Salesforce Mobile App Offline Settings.

Configure offline settings to allow for creating, editing, and deleting records.

Ensure that the Contact object is available for offline access.

This functionality encourages reps to use Salesforce directly by mitigating connectivity constraints.

For implementation details, refer to Salesforce Mobile App Offline.


Question #4

An app builder wants to create a custom object and 10 fields.

What should they use to create the object, fields, and relationships quickly from one place?

Reveal Solution Hide Solution
Correct Answer: A

To create a custom object along with multiple fields and relationships efficiently from a single interface, the Schema Builder is the ideal tool:

A . Schema Builder. This graphical tool provides a drag-and-drop interface for creating and modifying objects and fields in Salesforce, allowing for a visual layout of database schema.

Steps to use Schema Builder:

Go to Setup Schema Builder.

Drag the 'Object' element into the schema area to create a new custom object.

Define the object's properties (e.g., label, API name).

Drag field elements like Text, Number, or Lookup into the object to create fields.

Configure each field's properties according to your requirements.

Connect objects via lookup or master-detail relationships by dragging the relationship fields between them.

Save the layout to create all elements in Salesforce.

For more information, review Salesforce's Schema Builder documentation.


Question #5

DreamHouse Realty wants to display a weather map component on a Lightning record page when a house is scheduled for a showing.

How should the app builder meet the requirement?

Reveal Solution Hide Solution
Correct Answer: A

To display a weather map component on a Lightning record page conditionally:

A . Component visibility should be used. This feature in the Lightning App Builder allows components on a Lightning page to be displayed based on specific criteria, such as field values or user attributes. In this case, the app builder can set the visibility of the weather map component to only appear when a house is scheduled for a showing based on the relevant field values.

For more details on setting up conditional component visibility, review the guide on Dynamic Lightning Pages.
