Chatbot Cognitive Class Practice Test

At the beginning of a conversation in a dialog with multiple nodes, the system is typically designed to initiate with a predefined entry point to establish context and guide the interaction. The Welcome node serves this purpose by greeting the user, setting a friendly tone, and often outlining the capabilities of the chatbot or guiding the user on what to expect next. This structured approach helps in organizing the conversation flow and ensures that the user feels acknowledged from the outset.

The other nodes, such as Goodbyes and Thank You, are generally used at specific points within the conversation rather than at the beginning. The Goodbyes node would typically execute when the conversation is concluding, while the Thank you node is often used to express gratitude for user engagement, usually towards the end of the interaction. The notion that any node can execute randomly would disrupt the flow of conversation and likely lead to user confusion, which is why a defined starting point like the Welcome node is critical in dialog design.
