By default, Vlocity Attributes are:

• A. Shared across all objects
• B. Shared across Account and Contact objects only
• C. Specific by Record Type
• D. Specific by Object Type

Answer: (A)

Vlocity Attributes act as flow-wide variables in an OmniStudio session. By design, once you set an Attribute, its value is available to any step and any object involved in that execution context, so it’s shared across all objects in the flow. This cross-object accessibility makes it easy to pass data—like an ID or a computed value—from one part of the process to another without duplicating storage for each object. If you need to limit scope, you would structure the flow differently or use separate attributes, but the default behavior is cross-object sharing. The other options don’t fit because the default isn’t restricted to specific objects, record types, or a subset of objects.
