Comprehensive and Detailed Step-by-Step Definition of a Spoke: A "spoke" is a scoped application or component of an application that contains Flow Designer actions and integrations. Spokes provide reusable functionality and are typically used to extend the capabilities of Flow Designer. Why It's Called a Spoke: Spokes are part of the ServiceNow Flow Designer framework. They contain predefined actions that are reusable across multiple flows. For example, an "Email Spoke" might include actions for sending emails or managing email configurations. Why Other Options Are Incorrect: Option B (Flow): This refers to an individual flow, not the application containing reusable actions. Option C (Bundle): There is no such term as "Bundle" specific to Flow Designer in ServiceNow. Option D (Action): While flows contain actions, the scoped application that houses these actions is referred to as a spoke. Reference: ServiceNow Developer Documentation on Flow Designer Spokes.
