What type of rule identifies an error code in the system?

• A. Routing Rule
• B. Workqueue Rule
• C. Validation Rule
• D. Processing Rule

Answer: (B)

When an error code is generated, it comes from checks that ensure data meets required standards. A validation rule enforces what the data must look like—proper formats, required fields, permitted values. If the input fails these checks, the system raises an error and assigns a code to describe the problem. That makes the validation rule the mechanism that identifies and communicates error codes.

Routing rules decide where to send items, workqueue rules manage task queues, and processing rules outline steps to perform. They don’t inherently generate or identify error codes the way validation checks do.
