Expected Plat-Dev-210 Exam Topics, as suggested by Salesforce :
  • Topic 1: Flexcards: This section of the exam measures the skills of a Solution Architect and covers the ability to design and configure FlexCards based on specific business requirements. It evaluates the candidate's knowledge in selecting appropriate card styles, defining data sources and fields, and implementing user actions across different card states. Additionally, this domain tests the understanding of constructing the underlying JSON data structure that powers the FlexCards framework, ensuring that the configured cards meet both functional and technical specifications.
  • Topic 2: Omniscripts: This portion of the exam measures the skills of a Business Analyst and focuses on the use of OmniScripts to create dynamic, guided user experiences. It includes comparing and contrasting various OmniScript elements and their configurations to fulfill given use cases. The section also examines the candidate's understanding of the JSON structure that supports OmniScripts, as well as the ability to select appropriate elements and properties to address functional requirements effectively.
  • Topic 3: Integration Procedures: This section measures the skills of an Integration Architect and involves designing and configuring Integration Procedures to automate processes and integrate systems. It requires comparing and contrasting different elements and configurations within Integration Procedures to meet specific use cases. Candidates are also tested on selecting the correct elements and properties to satisfy functional requirements, ensuring seamless data flow and process automation.

Expression Sets and Decision Matrices often appear as conditional logic problems where you must determine the final output given priority, fall through rules, and expression evaluation order. A team member who passed advises mastering expression syntax, operator precedence, and end-to-end test cases so you can pick the correct rule under time pressure.

The troubleshooting and deployment questions felt like practical consulting work, so I spent time reading debug logs and tracking down why a card was not rendering or a script was failing silently. That prep paid off and I managed to pass on my first attempt.

Omnistudio Data Mappers questions test how to transform nested source records into complex target structures and how to handle lookups, constants, and null values inside mappings. I passed the exam and suggest practicing real mapping scenarios, learning mapping functions, and validating array and null behavior to catch subtle transformation issues.

Expression Sets and Decision Matrices showed up more than I expected, especially around maintainability and where to put business logic. I passed by drilling scenarios that compare rules versus script logic and by reviewing how changes impact testing.

Integration Procedures questions often ask you to optimize a sequence of actions and decide whether to use synchronous aggregates, subprocedures, or error handling patterns for best performance. I passed the exam and thanks Pass4Success for providing a good collection of exam questions for preparation in a short time, focus on step order, caching, and transaction boundaries when you study.

Integration Procedures and Data Mappers were the trickiest because the exam expects you to know when to transform data where, not just the definitions. I passed once I practiced mapping nested JSON and checking the output with real sample payloads.

Omniscripts challenges frequently present a broken data flow where a DataRaptor extract or a remote action is misconfigured and you must pick the correct fix. A colleague passed the exam and recommends studying the Omniscript step lifecycle, input and output JSON, and the differences between data and UI steps to debug these scenarios quickly.

Flexcards questions often test which data source and binding pattern to use when displaying aggregated records, sometimes asking you to choose between client-side actions and server-side merges. I passed the exam and found drilling into event actions, data source templates, and caching behavior was the most helpful.

Free Salesforce Plat-Dev-210 Exam Actual Questions

Note: Premium Questions for Plat-Dev-210 were last updated On Aug. 25, 2026 (see below)

Question #1

An OmniStudio Developer has configured an OmniScript to be embedded in an external web application that is not Salesforce. What is the primary method used to embed the OmniScript in this external channel?

Reveal Solution Hide Solution
Correct Answer: B

For off-platform use, OmniStudio uses OmniOut so LWC OmniScripts and FlexCards can run on third-party websites. Salesforce documentation explains that an activated OmniScript can be downloaded as an Off-Platform LWC and then added to the OmniOut project for integration into the external application. This makes option B correct because the external site embeds the OmniScript as a Lightning Web Component artifact, not as a Visualforce page. Visualforce is Salesforce-hosted legacy UI technology and is not the primary external embedding model. A REST API could call backend logic, but it would not render the OmniScript user interface. An Integration Procedure call only executes server-side logic; it does not embed the guided OmniScript experience.

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


Question #2

A developer has a requirement to create a child FlexCard that contains all of its parent FlexCard's records In a Datable How should the developer configure the parent FlexCard's Node?

Reveal Solution Hide Solution
Correct Answer: B

The Node field for the parent FlexCard should be set to {Records}, which is an array of all the records retrieved by the parent FlexCard data source. This will allow the child FlexCard to access the records and display them in a DataTable.


Question #3

Which calculation procedure version in the list would execute on 2/15/2020at 12:00 PM?

Reveal Solution Hide Solution
Correct Answer: B

the calculation procedure version that would execute on 2/15/2020 at 12:00 PM is the one that has the start date time and end date time that include that date and time, and also has the highest priority among the enabled versions. In this case, only version number 4 meets these criteria, as it has a start date time of 2/1/2020 12:00 AM, an end date time of 4/1/2020 12:00 AM, a priority of 1, and is enabled. The other versions either have a different start or end date time, a lower priority, or are not enabled.


Question #4

What OmniStudio tool pre-populates the data m a PDF used by an OmniScript?

Reveal Solution Hide Solution
Correct Answer: D

According to theDataRaptor Transform Overviewpage, a DataRaptor Transform can be used to ''pre-populate data in PDFs used by OmniScripts''.


Question #5

A developer is creating an OmniScript that provisions trail orgs to their customers. The following text block in the Omniscript uses a merge code to display the ID for the new trail org:

Reveal Solution Hide Solution
Correct Answer: B

The correct syntax for merge codes in OmniScript is %%sNodeName%%, where NodeName is the name of the JSON node in the data source. The other options are either missing the s or using incorrect symbols.
