1. Which Foundry application is primarily designed for building interactive
operational applications with a point-and-click interface?
A. Quiver
B. Workshop
C. Pipeline Builder
D. Code Workbook
Correct Answer: B. Workshop
Rationale: Workshop is Foundry's object-oriented application builder for creating
interactive applications for operational users.
2. What is the primary data layer used by Workshop applications?
A. Object Data Layer
B. File System Layer
C. SQL Warehouse Layer
D. Media Layer
Correct Answer: A. Object Data Layer
Rationale: Workshop applications primarily use the Object Data Layer, allowing
builders to work with objects, properties, and links.
3. Which Ontology primitive represents a real-world entity such as a customer,
aircraft, or machine?
,A. Action
B. Function
C. Object
D. Event
Correct Answer: C. Object
Rationale: Ontology objects represent entities in the domain and expose their
properties and relationships to applications.
4. What is the purpose of a link between two Ontology object types?
A. To execute Python code
B. To represent a relationship between objects
C. To create a dashboard
D. To authenticate users
Correct Answer: B. To represent a relationship between objects
Rationale: Links define relationships between object types and allow applications
and functions to traverse those relationships.
5. Which Foundry feature is intended to provide controlled writeback to
Ontology data?
A. Actions
B. Quiver
C. Object Explorer
D. Charts
Correct Answer: A. Actions
Rationale: Actions provide meaningful, controlled building blocks for creating,
editing, deleting, and linking object data.
6. Which Workshop component is most appropriate for displaying a collection of
Ontology objects in rows and columns?
A. Object Table
B. Metric Card
,C. Button Group
D. Media Widget
Correct Answer: A. Object Table
Rationale: The Object Table is designed to display and interact with object sets in a
tabular format.
7. What is a Workshop variable primarily used for?
A. Storing and moving typed values through a module
B. Creating physical servers
C. Managing Foundry licenses
D. Replacing Ontology objects
Correct Answer: A. Storing and moving typed values through a module
Rationale: Variables hold typed values and allow widgets, events, and functions to
interact with application state.
8. Which of the following can be represented by a Workshop variable?
A. Objects and object sets
B. Strings and numbers
C. Dates and timestamps
D. All of the above
Correct Answer: D. All of the above
Rationale: Workshop variables support many types, including object sets, strings,
numbers, booleans, dates, timestamps, arrays, structs, and geospatial types.
9. What happens when a Workshop event is triggered?
A. It can cause configured application behavior
B. It permanently deletes the module
C. It automatically creates a new Ontology
D. It disables all users
, Correct Answer: A. It can cause configured application behavior
Rationale: Events can update variables, navigate between views, execute actions,
refresh data, and perform other configured behaviors.
10. Which event could be used to respond when a user selects a row in a
Workshop table?
A. Row selection event
B. Server restart event
C. Pipeline completion event only
D. Dataset deletion event
Correct Answer: A. Row selection event
Rationale: Row-selection events can update variables or trigger other configured
behavior based on the selected object.
11. What is a Function in Foundry application development?
A. Server-side code that executes business logic
B. A visual chart
C. A user password
D. A static image
Correct Answer: A. Server-side code that executes business logic
Rationale: Foundry Functions execute server-side logic and can read Ontology
data, perform computations, and make Ontology edits.
12. Which programming languages are supported for Foundry Functions?
A. JavaScript only
B. TypeScript and Python
C. Java only
D. C# and Go only
Correct Answer: B. TypeScript and Python
Rationale: Foundry Functions support TypeScript and Python for server-side
