Palantir Foundry Application Developer Certification Exam
The Application Developer certification focuses on building and maintaining custom user-facing
applications on top of the Ontology. The exam is divided into four key domains: Application
Design (30%), Application Implementation (30%), User Experience and Cross-Application
Workflows (20%), and Application Maintenance (20%) . Candidates must be proficient in tools like
Workshop, Quiver, Slate, and Ontology Manager, as well as concepts like Object Types, Actions, and
Functions .
1. A business user needs to explore object relationships without any pre-built configuration. Which tool
should you recommend?
A) Workshop
B) Slate
C) Object Explorer
, Page 2 of 108
D) Quiver
Answer: C
Rationale: Object Explorer is an exploratory, walk-up usable tool that allows users to search, filter, and
traverse links without pre-configuration .
2. You need to build a highly customized, code-heavy application that interacts directly with datasets,
not just the Ontology. Which tool is most appropriate?
A) Workshop
B) Slate
C) Quiver
D) Object Views
Answer: B
Rationale: Slate is a flexible application builder requiring technical knowledge that can interact directly
with Foundry datasets, unlike Workshop which is limited to the Ontology .
3. What is the primary purpose of the Ontology in Palantir Foundry?
A) A data storage system for raw files
B) An operational layer that serves as a digital twin of the organization
, Page 3 of 108
C) A code repository for Python transforms
D) A visualization library for charts
Answer: B
Rationale: The Ontology sits on top of digital assets and connects them to real-world counterparts,
acting as an operational digital twin .
4. Which elements are considered the "semantic" components of the Ontology?
A) Actions and Functions
B) Objects, Properties, and Links
C) Pipelines and Transforms
D) Dashboards and Reports
Answer: B
Rationale: Objects, Properties, and Links define the structure and meaning of data, representing the
semantics of your organization .
5. A developer wants to implement business logic with arbitrary complexity to enable change in the
Ontology. What should they use?
A) Object Explorer filters
, Page 4 of 108
B) Foundry SQL
C) Functions
D) Static datasets
Answer: C
Rationale: Functions allow authors to write and evolve complex business logic that can be executed
quickly in operational contexts like dashboards .
6. A user needs to combine multiple resources (dashboards, Workshop apps, Object Views) into a single
curated workspace. What tool should you use?
A) Quiver
B) Slate
C) Carbon
D) Map
Answer: C
Rationale: Carbon enables combining various Foundry resources to create highly curated workspaces for
operational users .
