A user's message 'I need help with my bill' could match either a 'View Bill' action or a 'Dispute a Charge' action with similar confidence scores. The engineer wants the assistant to ask the user to clarify which they mean rather than guessing. Which feature should be configured?

watsonx Assistant's disambiguation (clarification) feature activates when two or more actions have similar confidence scores for a given utterance. It presents the top candidate action titles to the user as selectable options, letting them self-select the correct intent. This is cleaner than merging unrelated actions or trying to out-train ambiguity with more examples. The correct answer, "Enable clarification (disambiguation) in the assistant settings so it presents matched action titles for the user to select", directly satisfies the scenario because it aligns with watsonx Assistant's design principles and the specific capability being tested. The incorrect options ("Merge the two actions into one and use slot filling to determine which sub-task to perform", "Add more training examples to both actions until one always wins with higher confidence", "Create a single catch-all action that routes based on keywords in a long condition chain") may appear relevant but each misses a key requirement or introduces a step that is either unnecessary or belongs to a different workflow. Mastering the distinction between these approaches is essential for effective watsonx Assistant implementations and is a core focus of the Domain 1: Build Conversational Flows section of the certification exam.
