MikroTik RouterOS allows you to assign one of 8 different priority levels to each queue. These range from 1 (highest) to 8 (lowest). This allows for traffic shaping and prioritization in simple queues and queue trees.
These priority levels are used when multiple queues are competing for bandwidth or processing time. They influence which traffic gets handled first when congestion occurs.
* A. 16 ##Invalid. Only 8 supported.
* B. 1 ##Not correct. Only says one value; MikroTik supports multiple.
* C. 8 ##Correct. There are 8 valid priority values.
* D. 0 ##Priority 0 is not valid in MikroTik queues.
MTCNA Course Manual - Queues and Priorities:
"MikroTik queues support 8 priority levels (1-8). These affect which traffic is processed first." Rene Meneses Study Guide - QoS Mechanics:
"You can select between 8 priorities. These are configured per queue to define traffic importance." Terry Combs Notes - Simple Queues:
"Only 8 priority values exist. They follow a numerical scale from 1 to 8, not 0 or beyond."
