How many initial states can be configured in a State Machine?

In a State Machine, the configuration allows for a single initial state, which serves as the starting point for the process flow. This is crucial because the initial state defines where the execution begins and provides a clear entry point into the model. Having a single initial state simplifies the understanding of the flow of control in the State Machine and ensures consistency in how transitions are processed.

Each State Machine must have one defined entry point to ensure that once the machine is activated, it knows exactly where to begin. This rule is fundamental in designing state-based processes, as having more than one initial state could lead to ambiguity on which state should be entered first, making the process less predictable.

Other choices cannot represent the nature of State Machines accurately. For example, zero initial states would make it impossible to start any process, while two or more initial states would violate the principle of having a clearly defined starting point for execution. Thus, the answer indicating one initial state aligns perfectly with the standard practices of State Machine configuration.
