PALANTIR DATA ENGINEERING CERTIFICATION EXAM
Question: What is the primary purpose of a source in Palantir Foundry?
A. To store transformed production datasets
B. To represent a connection between Foundry and an external data
system
C. To define an Ontology object type
D. To schedule pipeline builds
Correct Answer: B. To represent a connection between Foundry and
an external data system
Rationale: A source represents the configured connection between
Foundry and an external system, such as a database, cloud storage
location, filesystem, SAP system, or REST API. After establishing the
source, data syncs can be configured to bring selected data into
Foundry. Source configuration generally involves ensuring network
access, provisioning valid credentials, and creating the source within
Data Connection.
Question: Before Foundry can authenticate against an external data
source, what must generally be available?
A. Valid credentials
B. A completed Ontology
C. A Workshop application
D. A Quiver visualization
Correct Answer: A. Valid credentials

, PALANTIR DATA ENGINEERING CERTIFICATION EXAM
Rationale: Foundry requires appropriate credentials to authenticate
with external systems when establishing many source connections.
Credentials are part of the connection setup process and should be
provisioned before or during source configuration according to the
architecture and source type being used. Proper credential
management is essential for reliable and secure data integration.
Question: Which Foundry capability is most directly responsible for
showing how resources and data flow through the platform?
A. Workshop
B. Data Lineage
C. Object Explorer
D. Slate
Correct Answer: B. Data Lineage
Rationale: Data Lineage provides visibility into how resources interact
and how data flows through the platform. This is especially valuable for
data engineers when investigating downstream dependencies,
understanding the effects of changes, tracing dataset origins, and
troubleshooting pipeline issues. Lineage is a major advantage when
managing complex interconnected data systems.
Question: A data engineer needs to transform datasets using SQL.
Which category of Foundry data-engineering functionality supports this
work?
A. Transform authoring by language
B. Only Ontology configuration
C. Only application development
D. Only visualization tooling
Page 2 of 48
, PALANTIR DATA ENGINEERING CERTIFICATION EXAM
Correct Answer: A. Transform authoring by language
Rationale: Foundry supports data transformations authored using
multiple languages, including SQL, Python, Java, and R. This gives
engineers flexibility to select an appropriate development approach
based on the transformation requirements, team expertise, available
libraries, and computational needs.
Question: What is the main benefit of data lineage when modifying an
upstream dataset?
A. It automatically prevents all pipeline failures
B. It identifies potential dependencies and downstream effects
C. It converts the dataset into an Ontology object
D. It permanently locks all downstream datasets
Correct Answer: B. It identifies potential dependencies and
downstream effects
Rationale: Data lineage helps engineers understand relationships
between upstream and downstream resources. Before making a
significant schema or logic change, engineers can use lineage
information to assess what pipelines, datasets, or other resources may
be affected. This supports safer change management and reduces the
risk of unexpected downstream disruption.
Question: Which data transfer pattern is explicitly supported by
Foundry's data integration capabilities?
A. Batch only
B. Streaming only
C. Batch, micro-batch, and streaming
D. Manual CSV upload only
Page 3 of 48
, PALANTIR DATA ENGINEERING CERTIFICATION EXAM
Correct Answer: C. Batch, micro-batch, and streaming
Rationale: Foundry's data integration framework supports multiple
approaches for transferring data, including batch, micro-batch, and
streaming. This allows engineers to design pipelines appropriate for the
latency and operational requirements of the use case rather than
forcing every workload into a single ingestion pattern.
Question: A team needs to connect Foundry to a PostgreSQL database.
What Foundry concept represents that external connection?
A. Source
B. Object type
C. Action type
D. Function
Correct Answer: A. Source
Rationale: In Foundry, a source represents the connection to an
external system. PostgreSQL databases are among the types of systems
that can be represented through a source. Once the connection is
established and configured, syncs can be created to bring relevant data
from that system into Foundry.
Question: What is the primary purpose of a sync after a source has
been configured?
A. To visualize data in a dashboard
B. To bring configured sets of data from the source into Foundry
C. To define user permissions for every project
D. To create Ontology actions automatically
