Two mangle rules defining different mangle marks for the same traffic type will make it have both mangle marks.

In MikroTik routers, mangle rules are used to manipulate packets for various purposes, such as traffic marking for quality of service (QoS) or filtering. When two mangle rules are defined for the same traffic type, only the first matching mangle rule will apply, and that will determine the mangle mark for the packets. As a result, packets cannot have multiple mangle marks simultaneously; they can only inherit the mark specified by the first rule that matches the criteria defined in the configuration.

Therefore, it is asserted that the statement is false since only one mangle mark can be assigned to a packet at a time, despite the presence of multiple rules targeting the same traffic type. Understanding this functionality helps ensure proper traffic management and analysis on MikroTik devices.
