The "Configure Catalog Defaults" task in the Setup and Maintenance work area allows administrators to define system-wide default behaviors for learning items. This includes setting the default for the "Allow learners who completed this learning to be assigned it again" option. By disabling this default, all new learning assignments will automatically exempt learners who have a prior completion record for the same item. This approach ensures consistency and eliminates the need for administrators to manually configure this rule for each individual assignment, directly addressing the customer's requirement for a global setting.

A. Creating a new version is a manual, per-course action and does not establish a system-wide default behavior for all assignments.

C. A custom script is not a standard configuration method and is unnecessary when a built-in feature for setting defaults exists.

D. Filtering a report is a reactive measure that only affects reporting data; it does not prevent the actual re-assignment of the learning.
