Which of the following is one type of rule that makes workqueues function?

• A. Routing Rules
• B. Data Sorting Rules
• C. City Rules
• D. Access Control Rules

Answer: (A)

Routing rules guide how tasks move between queues and to specific workers based on attributes like type, priority, or source. This directing logic is what makes workqueues function, because it distributes work to the right place for processing and enables parallel handling and prioritization. For example, a task labeled as urgent can be routed to a high-priority queue, while routine tasks go to a standard queue. Data sorting within a queue rearranges items but doesn’t determine where they go, and options like city rules or access control rules govern unrelated aspects such as governance or security. So routing rules are the mechanism that actually enables effective workqueue operation.
