Free Salesforce DEX-403 Exam Actual Questions

Note: Premium Questions for DEX-403 were last updated On 31-07-2025 (see below)

Question #1

Ursa Major Solar (UMS) is looking to hire some new employees. UMS wants to allow the same applicant to apply for multiple open positions using a single application.

What should an app builder recommend to meet these requirements?

Reveal Solution Hide Solution
Correct Answer: D

Create a master-detail relationship field on Applicant__c to Application__c is what the app builder should recommend to meet the requirements of allowing the same applicant to apply for multiple open positions using a single application. This will create a many-to-many relationship between Applicant__c and Open_Position__c using Application__c as a junction object. Create a master-detail relationship on Open_Position__c to Application__c, create a master-detail relationship field on Application__c to Open_Position__c, and create a lookup relationship field on Applicant__c to Application__c are not valid or correct ways to create a many-to-many relationship.


Question #2

Universal Containers require different fields to be filled out at each stage of the Opportunity sates process.

What configuration steps can an app builder use to meet this requirement?

Reveal Solution Hide Solution
Question #3

Universal Containers wants to deliver purchased containers to remote construction address. In these cases, the customers will supply UC with the coordinates to the location.

What type of field should the app builder use to capture this information?

Reveal Solution Hide Solution
Question #4

What option is available to an App Builder when defining an object-specific Create Record custom action? Choose 2 answers

Reveal Solution Hide Solution
Correct Answer: A, C

The app builder has two options available when defining an object-specific Create Record custom action:

Pre-Defining field values on the target object. This means that the app builder can specify default values for certain fields on the target object when creating a new record using the custom action.

Specifying the fields and layout of the action. This means that the app builder can choose which fields to include in the action and how they are arranged on the screen. Option B and D are not options available when defining an object-specific Create Record custom action.


Question #5

An app builder at DreamHouse Realty created a custom object which has fields containing data from two different objects via related lookups.

What is needed to create "with" or "without* reports on the new custom object?

Reveal Solution Hide Solution
Correct Answer: D

To create ''with'' or ''without'' reports on the new custom object, a custom report type is needed. A custom report type defines the relationship between one or more standard or custom objects for reporting purposes. It allows users to select which fields they want to display in their reports and filter by related objects.
