Free Practice Questions for Salesforce OmniStudio-Developer Exam

According to the OmniStudio Developer Guide, “DataRaptor Transform actions can convert JSON to XML and vice versa.” Therefore, the correct answer is C.

 A DataRaptor Extract can retrieve data from multiple objects using extraction steps and JSON paths. However, if the data is from a single object, only one extraction step is needed. The Extract JSON Path can use dot notation to access related fields from that object, such as Contact.Account.Name.

Two separate Group elements with mutually exclusive conditions provide the cleanest declarative control. One Group should execute only when updateBillingAddress is true and updateShippingAddress is false. The other Group should execute only when updateShippingAddress is true and updateBillingAddress is false. This enforces that only one address update path runs. A single OR condition would allow either or both flags to be true, so it cannot prevent simultaneous updates. A Try-Catch Block reacts after an error occurs; it is not the right way to express business-rule branching. An HTTP Action would add unnecessary external dependency. Integration Procedure blocks and groups are designed to run related steps conditionally, so mutually exclusive Group conditions are the correct structure.

The child OmniScript must receive specific nodes from the parent OmniScript’s data JSON, so the developer should pass them through Additional Input key/value pairs on the child OmniScript element. Additional Input is used to pass named values into an action or embedded component when the child process needs specific data from the current script context. ContextId would pass only a record identifier, not full Address and Contact JSON nodes. PreFill is used to populate data into an OmniScript, but the question asks which property on the child OmniScript element should be used to pass parent nodes. LWC Component Override is unrelated because it replaces rendering behavior rather than mapping parent script data. Therefore, Additional Input is the correct configuration.

 The Params node contains the data that is passed from the parent FlexCard to the child FlexCard. The developer should use {Params.postalcode} to refer to the contact’s postal code in the child FlexCard.

The wording of this question is imperfect. Official Salesforce documentation identifies the OmniStudio Build Tool, formerly Vlocity Build Tool, as the Node.js command-line automation tool designed to package, export, and deploy OmniStudio DataPacks in a source-control-friendly format. Since “OmniStudio Build Tool” is not one of the listed choices, the only command-line deployment option given is Salesforce Command-Line Interface. Visual Studio Code Integrated Terminal is merely a shell host, not a migration tool. Metadata API is a deployment API, not the OmniStudio-specific CLI named in the documentation. Change Data Capture is an event-streaming feature and has nothing to do with OmniStudio component migration. So D is the only usable answer from the provided options, but the technically precise tool name is OmniStudio Build Tool/Vlocity Build Tool.

================

The correct answer is D. Data Mapper Turbo Extract, based on best practices in the official OmniStudio documentation.

From the OmniStudio Developer Guide → DataRaptors → Turbo Extract:

DataRaptor Turbo Extract is a lightweight, high-performance extract designed specifically for retrieving data from a single Salesforce object, where no data transformation or complex joins are required.

It is recommended over DataRaptor Extract for performance reasons when only one object and minimal transformation is needed.

Why not the others?

A. DataRaptor Load is used for writing data to Salesforce, not retrieving.

B. DataRaptor Transform is used when you need to transform data, not simply extract it.

C. DataRaptor Extract can be used, but Turbo Extract is preferred for the use case of single object, no transformation — per best practices.

he Aggregation Step in a calculation procedure allows the developer to perform aggregate functions such as SUM, COUNT, MIN, MAX, and AVG on the output of a previous step. The developer can use this step to calculate the sum of the entire base price by specifying the field name and the aggregation function

The correct tool is the Test Data and Parameters panel in the FlexCard Designer. The requirement is specifically to test the FlexCard directly in its designer with different JSON inputs before deployment. The OmniScript Test Console is for OmniScript logic, not FlexCard data rendering. IDX Workbench is a migration/deployment tool, not the FlexCard’s built-in data-testing panel. A Data Mapper Turbo Extract preview only tests the Data Mapper query output; it does not validate how the FlexCard processes different JSON structures and renders states, fields, or conditional elements. Salesforce documentation for FlexCard testing describes adding test parameters in the FlexCard Designer and previewing/debugging the card using those values, which directly supports option C.

A Text Block element allows the developer to display read-only text in a table format, using merge codes to dynamically include data from the data JSON. A Rich Text Area element is used to display formatted text with images and links. A Text Area element is used to display editable text in a single line or multiple lines. An Edit Block element is used to display editable fields in a form layout.
