PREPARATION
1. A development team is building a new workflow in Palantir Foundry. Which capability is
primarily used to transform raw data into curated datasets?
A. Workshop
B. Ontology
C. Pipeline Builder
D. Contour
Correct Answer: C. Pipeline Builder
Rationale: Pipeline Builder is designed for creating and managing data transformation
workflows. Workshop focuses on user applications, Ontology models business entities, and
Contour is used for geospatial analysis.
2. A Foundry developer wants to ensure that a dataset refreshes automatically whenever
upstream source data changes. What is the best approach?
A. Configure lineage-based dependencies
B. Export the dataset daily
C. Create a manual refresh schedule
D. Disable pipeline triggers
Correct Answer: A. Configure lineage-based dependencies
Rationale: Lineage-driven dependencies allow downstream datasets to refresh automatically
when upstream data changes. The other options either require manual intervention or do not
support automated synchronization.
3. Which Foundry feature provides visibility into upstream and downstream data
relationships?
A. Workshop
B. Lineage
C. Code Workbook
D. Marketplace
,Correct Answer: B. Lineage
Rationale: Lineage provides traceability across data assets and transformations. This capability
is essential for troubleshooting, governance, and impact analysis.
4. A developer needs to build a reusable transformation that can be applied across multiple
datasets. What is the preferred approach?
A. Duplicate transformation logic
B. Create separate pipelines
C. Build a reusable function or module
D. Export datasets manually
Correct Answer: C. Build a reusable function or module
Rationale: Reusable functions improve maintainability, consistency, and efficiency while reducing
technical debt caused by duplicated logic.
5. During Certification Preparation, a developer notices inconsistent values in a customer
dataset. What should be performed first?
A. Data quality assessment
B. Ontology publication
C. Dashboard deployment
D. User provisioning
Correct Answer: A. Data quality assessment
Rationale: Validating data quality before downstream development prevents inaccurate
reporting, application errors, and unreliable business decisions.
6. Which action best supports secure application development in Foundry?
A. Sharing all datasets broadly
B. Applying least-privilege access controls
C. Disabling audit logs
D. Using public permissions
Correct Answer: B. Applying least-privilege access controls
Rationale: Least-privilege access reduces security risks by ensuring users only receive
permissions necessary for their roles.
7. A business stakeholder wants a visual interface for interacting with operational data. Which
Foundry tool is most appropriate?
A. Workshop
B. Pipeline Builder
, C. Data Connection
D. Code Repository
Correct Answer: A. Workshop
Rationale: Workshop enables developers to create business applications and user-facing
interfaces using Foundry data assets.
8. What is the primary purpose of the Foundry Ontology?
A. Managing operating systems
B. Monitoring network traffic
C. Modeling business entities and relationships
D. Encrypting datasets
Correct Answer: C. Modeling business entities and relationships
Rationale: The Ontology provides a semantic layer that represents real-world business objects
and their relationships.
9. A pipeline suddenly fails after a schema change in a source system. What should the
developer review first?
A. Dataset permissions
B. Pipeline logs and schema mappings
C. User training records
D. Application branding
Correct Answer: B. Pipeline logs and schema mappings
Rationale: Schema changes commonly cause transformation failures. Reviewing logs and
mappings helps identify the root cause quickly.
10. Which practice improves maintainability of Foundry code repositories?
A. Using meaningful version control commits
B. Avoiding documentation
C. Hardcoding values
D. Combining unrelated functions
Correct Answer: A. Using meaningful version control commits
Rationale: Clear commit histories support collaboration, troubleshooting, auditing, and future
enhancements.
11. A developer needs to join customer and order datasets. What should be verified before
performing the join?
