NVIDIA NCP-OUSD Exam Syllabus Topics:

Topic	Details
Topic 1	Data Exchange: Covers creating data mapping documents and building custom importers, exporters, and scripts to interchange data with OpenUSD pipelines.
Topic 2	Content Aggregation: Covers building modular, reusable components and using instancing strategies to efficiently assemble and override assets in large, optimized scenes.
Topic 3	Data Modeling: Covers USD and Sdf data structures including prims, properties, primvars, value types, time samples, and built-in schemas.
Topic 4	Pipeline Development: Covers high-level pipeline design tasks including asset management, versioning, USD exporter hooks, build configurations, and dependency management.
Topic 5	Debugging and Troubleshooting: Covers introspecting USD stages to resolve composition issues, fix poorly authored data, and optimize scene load and render performance.

NEW QUESTION 17
Which option best describes the primary function of an inherit composition arc in OpenUSD?

Inherit arcs are a replacement for reference arcs when you have an opinion that needs to be stronger than opinions from a variant set.

Modifications to the inherited prim in stronger layer stacks allow for those overrides to be uniformly broadcast to all inheriting prims.

It provides a mechanism for implementing object-oriented programming (OOP) design patterns in your scene description design.

NEW QUESTION 18
What is the difference between external and internal references?

Internal references are always weaker than local opinions

External references target other layers, internal references target prims in the same layer

External references are only for geometry

Internal references can only target shaders

NEW QUESTION 19
Which module provides vector classes like Vec3d?

Usd

Sdf

UsdGeom

NEW QUESTION 20
What is a way to utilize both USDA and USDC as part of a scene?

Use USDC for prims related to shading and USDA for all other prim types.

Use USDA for non-geometric prims and USDC for geometric and animation data.

Use USDA entirely as USDC is most helpful for when debugging issues with scenes.

NEW QUESTION 21
What is the primary purpose of asset structure in OpenUSD?

To simplify version control through standardized asset management and tracking

To maximize rendering performance through optimized data organization and caching

To empower the scalability of an organization and ecosystem and promote collaboration

To reduce storage requirements through efficient resource sharing and deduplication

NEW QUESTION 22
After switching upAxis Y→Z, why add xformOp:rotateX on /World?

To pack USDZ

To preserve visual “upright” orientation

To recompute normals

To reduce file size

NEW QUESTION 23
What is the fundamental data type in USD that enables API schemas to be non-destructively removed in stronger layers?

list ops

arrays

booleans

NEW QUESTION 24
Why are over specifiers used in sublayers?

To erase all prims

To transform geometry

To override existing opinions without redefining

To generate new materials

NEW QUESTION 25
What is the benefit of using geometric and shading variant sets separately?

Independent control allows flexible combinations of geometry and materials

It forces encapsulation automatically

It eliminates the need for payloads

It changes the default prim

NEW QUESTION 26
Which module provides the attribute type names like Float, String, Bool?

Usd

Sdf.ValueTypeNames

UsdGeom

NEW QUESTION 27
Why set a defaultPrim?

To enable time sampling

To reference a stage without specifying a target prim

To enable subdivision

To pack into USDZ

NEW QUESTION 28
How is opinion strength determined between sublayers?

Alphabetically

File size order

By their order in the subLayerPaths list

Randomly at runtime

NEW QUESTION 29
What kind of attribute is a good candidate for lofting?

Geometry vertices

Variant sets or extentsHint

Heavy textures

Animation caches

NEW QUESTION 30
For resilience across Assimp variants, mesh faces should be read from:

mesh.faces only

mesh.indices only

mesh.indices or fallback to mesh.faces

mesh.vertices

NEW QUESTION 31
Even in a well-encapsulated asset, why can referencing a child like /World/Cube (instead of /World) drop materials?

Because sublayers cannot carry materials

Because payloads auto-unload materials

Because specializes arcs override materials to defaults

Because the material may live on a sibling path not under /World/Cube

NEW QUESTION 32
What naming convention might indicate a public prim?

lower_case

UPPERCASE

Capitalized names

Names with underscores

NEW QUESTION 33
Which of these are valid types for custom attributes in OpenUSD? (Choose two.)

structs

assset paths

string arrays

dictionaries

NEW QUESTION 34
What should be avoided when using computational workstreams?

Hybrid workflows

Dynamically growing layer stacks over time

Using sublayers for data combination

Using primvars

NEW QUESTION 35
Which of these is not a valid attribute type in Sdf.ValueTypeNames?

Float

String

Token

Magic

NEW QUESTION 36
Which attribute requires two Vec3 values (min and max)?

size

extent

displayColor

radius

NEW QUESTION 37
What strategy can be used if a team needs both a fully packaged component and smaller “part” assets?

Replace assemblies with primvars

Publish multiple asset variations

Avoid using subcomponents

Use only shading layers

NEW QUESTION 38
Which file-type integration is unique to OpenUSD for on-the-fly composition?

Import scripts

File format plugins

USDZ packers

Hydra shader

NEW QUESTION 39
What happens when you compose sublayers in USD?

Only the last sublayer is visible

Contents are merged like an include, preserving all prims

The weakest sublayer deletes the others

Sublayers transform geometry automatically
