1. Which Palantir Foundry component is primarily responsible for orchestrating and
scheduling data pipelines?
A) Contour
B) Quiver
C) Code Workbook
D) Transforms
Answer: D
Rationale: Transforms in Foundry are the core building blocks for data pipelines;
they can be scheduled and orchestrated to run in a directed acyclic graph (DAG)
using Builds.
2. A developer needs to explore time-series data and detect anomalies interactively.
Which Foundry application is best suited?
A) Contour
B) Quiver
C) Fusion
D) Workshop
Answer: B
Rationale: Quiver is a time-series analysis tool in Foundry that supports anomaly
detection, visual time-series comparison, and interactive exploration.
3. You are asked to build a user-facing dashboard that allows filtering and real-time
updates from a dataset. Which tool should you use?
A) Code Workbook
, B) Quiver
C) Workshop
D) Contour
Answer: C
Rationale: Workshop is the application-building framework for creating interactive
dashboards and workflows with real-time data connections.
4. What is the purpose of Ontology in Palantir Foundry?
A) It is a data ingestion tool.
B) It is a graph database only.
C) It is a logical representation of objects, links, and actions that applications
consume.
D) It is a replacement for SQL.
Answer: C
Rationale: The Ontology provides a business-friendly abstraction layer, allowing
object-centric views, relationships, and actions across multiple datasets.
5. Which of the following can be used to transform raw data in Foundry using SQL?
A) Quiver
B) Code Workbook only
C) Contour only
D) Code Workbook and Contour
Answer: D
Rationale: Both Code Workbook (SQL cells) and Contour (visual transformations)
allow SQL-like logic; Code Workbook supports raw SQL, while Contour translates
visual steps to SQL.
6. In Foundry, what is a “Build” in the context of Transforms?
A) A manual export of data
B) An execution of a transform’s logic to produce a new dataset version
C) A user permission
D) A storage location
Answer: B
, Rationale: A Build computes outputs from inputs by running the transform’s code or
configuration, producing a versioned dataset.
7. A developer wants to enforce data quality checks before a dataset is used
downstream. What feature should they use?
A) Data Lineage
B) Expectations
C) Markdown preview
D) Ontology Actions
Answer: B
Rationale: Expectations in Foundry allow defining rules (e.g., not null, unique) on
datasets; builds fail if expectations are violated.
8. Which statement about Foundry’s version control is true?
A) Only Git is supported.
B) Code Repositories use Git branches and commits.
C) Version control is not available for datasets.
D) All changes are automatically merged.
Answer: B
Rationale: Code Repositories are backed by Git, providing branching, commits, and
merging; datasets also have immutable versioning.
9. An application developer needs to enable users to change object properties via a
UI, which then writes back to Foundry. What should they create?
A) A Data Connection
B) An Ontology Action
C) A Fusion Layer
D) A Contour transform
Answer: B
Rationale: Ontology Actions encapsulate write-back logic (e.g., updating property,
linking objects) that can be triggered from Workshops or other apps.
10. You are debugging a pipeline failure. Where would you find logs for a specific
transform run?
, A) In the Build Details pane of the dataset
B) Only in the Code Repository’s local log
C) In the Quiver time-series view
D) They are not stored for security reasons
Answer: A
Rationale: Each build shows logs, errors, and execution details within the dataset’s
Build Details, accessible in Foundry.
11. What is the primary use of Fusion in Foundry?
A) Business intelligence dashboards
B) Geospatial analysis and mapping
C) Machine learning model training only
D) Data integration with external clouds
Answer: B
Rationale: Fusion is Foundry’s geospatial application for visualizing and analyzing
spatial data, integrating with maps and geographic layers.
12. A developer needs to create a reusable transformation logic across several
projects. What should they use?
A) Copy-pasting code into multiple Code Workbooks
B) A Code Repository with shared libraries or transforms
C) Manual SQL scripts only
D) Quiver templates
Answer: B
Rationale: Code Repositories allow building libraries, functions, and reusable
transforms that can be imported across pipelines.
13. Which Foundry feature allows you to trace how a dataset was derived from
source systems?
A) Data Quality
B) Data Lineage
C) Ontology Explorer
D) Fusion
