MikroTik RouterOS supports prioritizing traffic in queues using a numerical priority system. The queue priority values range from 1 to 8, where:
* 1 = Highest priority (most preferred)
* 8 = Lowest priority (least preferred)
This means that traffic marked with priority 1 is processed before traffic with lower priorities. Priorities are used within simple queues, queue trees, and in some packet marking strategies.
Evaluation:
* A. 1 ##Correct. This is the highest priority.
* B. 256 ##Invalid priority value in MikroTik queues.
* C. 16 ##Priority range is only 1 to 8.
* D. 8 ##Lowest priority.
MTCNA Course Slides - QoS and Queuing:
"Queue priority values range from 1 to 8. Lower values indicate higher priority." Rene Meneses Study Guide - Traffic Management Section:
"MikroTik queues use priority values from 1 (highest) to 8 (lowest)."
Terry Combs Notes - QoS and Prioritization:
"Set queue priority to 1 for critical traffic like VoIP or routing protocols."
