Exam MTCNA Topic 2 Question 157 Discussion

Simple Queues in MikroTik are the most straightforward way to manage bandwidth per IP address or subnet.
To apply bandwidth limitations, you primarily need:
* target-address (the IP address or subnet you're shaping)
* max-limit (the maximum allowable upload/download bandwidth)
Other fields like dst-address can be used for advanced matching, but they are not required for basic bandwidth limiting.
* A. Correct. This is the minimum required configuration.
* B. Incorrect. dst-address is optional and unnecessary unless shaping traffic only to specific destinations.
* C. Incorrect. Lacks max-limit, which is essential for any bandwidth cap.
* D. Incorrect. Without target-address, the queue doesn't know which host or network to apply the rule to.
Extract from Official MTCNA Course Material - QoS Section:
"To shape traffic in a simple queue, the most basic configuration requires target-address and max-limit.
Target-address specifies which host or network to affect. Max-limit defines upload/download caps." Extract from Rene Meneses MTCNA Study Guide - QoS:
"A simple queue needs at least two values: target (the IP or range) and max-limit (limits for up/down in bits per second). Everything else is optional for basic shaping." Extract from Terry Combs Notes - Queues:
"Without a max-limit value, the queue does not restrict bandwidth. dst-address is rarely used in simple queues unless traffic is routed externally."
