+question="What type of field must be configured in the schema to display the results of a Master Data Hub match?"
+answers={[
+{ text: 'string' },
+{ text: 'number' },
+{ text: 'enum', isCorrect: true },
+{ text: 'date' }
+]}>
+The field must be an `enum` type. This is because the Master Data Hub needs a field that can hold a dynamic set of options, which are the results of the matching query. The `enum` field type is designed to handle a list of choices, making it the perfect fit for displaying the matched vendor, purchase order, or other data from your master database. If no match is found, it can display a corresponding message.
