Correct Answer: B
Question 93
How many wireless clients can connect, when wireless card is configured to mode=bridge?
Correct Answer: A
In MikroTik RouterOS, if a wireless card is configured to mode=bridge (also referred to as "station-bridge"), it can only be used to connect a single client device (MAC address) behind it. This is due to limitations in how 802.11 bridges MAC addresses. So: * A.#Correct - Only 1 MAC address can pass via wireless bridge mode (unless using WDS or 4-address mode) * B, C ##Too many clients for bridge mode * D.#Incorrect - Still only one client allowed per interface in bridge mode MTCNA Wireless Module - Wireless Modes: "Bridge mode allows one client only unless extended bridging protocols are used." Rene Meneses Guide - Wireless Bridging: "mode=bridge = one MAC behind the station. Use WDS for multiple MACs." Terry Combs Notes - Wireless Modes: "Station-bridge mode works like Ethernet, but only supports one MAC address unless using WDS."
Question 94
Which are necessary sections in /queue simple to set bandwidth limitation?
Correct Answer: A
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."
