Suggested Answer: C Vote an answer
The "Max Limit" value in MikroTik Simple Queues defines the maximum allowed bandwidth. In this case:
* Target Address: 192.168.1.10
* Target Upload = 1M # The host can upload at a maximum of 1 Mbps
* Target Download = unlimited # No restriction on download
This does not "guarantee" bandwidth - it enforces a ceiling. A guaranteed rate would require "Limit-at" to be set.
Evaluation:
* A.#This queue limits, it does not guarantee a minimum bandwidth.
* B.#Download is set to unlimited - no limitation.
* C.#Upload is limited to 1 Mbps - correct.
* D.#Download rate is unlimited - no guarantee or limit.
MTCNA Course Manual - Simple Queue Explanation:
"Max-limit sets the maximum throughput for upload/download. It's a ceiling, not a guarantee." Rene Meneses Guide - Simple Queues Explained:
"In this case, upload is capped at 1M. No burst or download limit is applied." Terry Combs Notes - Queue Properties:
"Always distinguish between 'limit-at' (minimum guarantee) and 'max-limit' (maximum cap)."
