Why is a well-designed model kind hierarchy important for an efficient pipeline?

• A.The composition engine can optimize based on the model kind hierarchy.
• B.Tools can rely on the model kind hierarchy for efficient stage traversal.
• C.The model kind hierarchy helps avoid duplication of pipeline data.

What key capability distinguishes an IsA schema from an API schema?

• A.An IsA schema can impart a typeName to a prim, whereas an API schema cannot.
• B.IsA schemas are always concrete, while API schemas are always non-concrete.
• C.API schemas can have relationships, while IsA schemas cannot.

Why would you not see a sphere when opening this scene?
#usda 1.0
(
defaultPrim = "wall_a_inst"
upAxis = "Z"
)
def Xform "wall_a_inst" (
instanceable = true
variants = {
string Emissive = "Default"
}
prepend variantSets = "Emissive"
)
{
def Sphere "Sphere"
{
}
variantSet "Emissive" = {
"Daytime" {
}
"Default" {
}
}
}

• A.Because "wall_a_inst" has instanceable=true and a composition arc, variants, the sphere that is inside of
  "wall_a_inst" but outside of its variantset is not part of the instanced scenegraph.
• B.The "Emissive" variant set is missing the material bindings for both "Daytime" and "Default".
• C.Sphere are guide geometry that are invisible by default.

Which statement accurately describes a key difference between native instancing and point instancing?

• A.Point instancing generates prototypes dynamically, while native instancing uses statically defined prims.
• B.Native instancing can only use a single prototype per scene, while point instancing can use multiple prototypes.
• C.Native instancing requires prototypes to be defined in separate files, while point instancing requires them in the same layer.
• D.Native instances are individually addressable prims in the scene hierarchy after composition, while point instances are not.

When developing a custom USD schema, what statements are true regarding API schemas versus typed schemas? Choose two.

• A.Multiple API schemas can be applied to a single prim, but a prim can only have one typed schema.
• B.API schemas require Python bindings while typed schemas can be implemented to only support C++.
• C.API schemas are more strict than typed and cannot define their own attributes or relationships.
• D.API schemas can be applied to multiple prim types while typed schemas define a specific prim type.
