Which component defines constraints that prevent assignment of tasks to agents?

• A. Task Filters
• B. Un-Assignment Constraints
• C. Work permits
• D. Skill requirements

Answer: (B)

Un-Assignment Constraints are the rules that prevent a task from being assigned to an agent. They encode conditions like unavailability, being over capacity, or lacking necessary qualifications, so the scheduler won’t select someone who shouldn’t take the job. This lets the system enforce business policies before matching a task to a resource. While task filters restrict which tasks are considered and skill requirements define needed capabilities, the explicit mechanism to block an assignment based on defined conditions is provided by the un-assignment constraints.
