Question 47
Which of the following keystrokes enables safe mode in console?
Correct Answer: D
Safe Mode in MikroTik CLI is a protective mode that helps revert any unintended changes if you get disconnected. It is activated by pressing Ctrl+X in older versions, but the current standard keybinding for enabling safe mode is Ctrl+S. MTCNA Course Material - Safe Mode: "To enable safe mode in the terminal, press Ctrl+S. A confirmation [Safe Mode] will appear in the prompt. If the terminal is closed or disconnected, the changes are rolled back." Rene Meneses MTCNA Study Guide - Terminal Commands: "Safe Mode can be activated using Ctrl+S. This is useful during remote configuration. It reverts changes if the terminal is closed." MikroTik Wiki - Safe Mode Section: "To enter safe mode, press Ctrl+S in CLI. This ensures configuration rollback if disconnected." Other options: * Ctrl+C terminates commands or CLI input * Ctrl+X may not activate safe mode in newer versions * Ctrl+D is used to log out in some Unix-like terminals Correct answer: Ctrl+S
Question 48
Consider the following diagram. We want to communicate from a device on LAN1 (192.168.0.0/24) to a device on LAN2 (192.168.1.0/24). Assuming that all necessary configurations are already included on R2, which of the following configurations in R1 would enable this communication?
Correct Answer: D
To route traffic from LAN1 (192.168.0.0/24) behind R1 to LAN2 (192.168.1.0/24) behind R2, R1 must know how to reach the destination network 192.168.1.0/24. The proper way is to add a static route on R1 pointing to the next hop IP address of R2's interface (192.168.99.2) connected via their shared transit network (192.168.99.0/24). According to: Rene Meneses MTCNA Study Guide - Routing Section: "A static route requires the destination prefix and the gateway (next-hop) IP address. The gateway should be reachable through a directly connected network interface." Terry Combs MTCNA Notes - Static Routing Example: "To route packets to a remote network, configure a static route specifying the destination network (e.g., 192.168.50.0/24) and the gateway IP (e.g., 10.0.0.2). Ensure that the gateway is reachable via a locally connected interface." MikroTik Wiki - Static Routing: "The most common usage of static routes is to forward packets for destination networks that are not directly connected. You must use the IP address of a reachable next-hop router." Option A incorrectly includes src-address, which is not part of a standard /ip route syntax. Option B uses "Ether1" as a gateway, which is syntactically invalid unless using recursive routing, which this situation does not require. Option C adds a route back to the local network - unnecessary and incorrect. Option E routes all traffic to R2, which is inefficient and not specific. Thus, only Option D adds the correct static route: /ip route add dst-address=192.168.1.0/24 gateway=192.168.99.2
Question 49
What protocol is used to find the hardware address of a local device?
Correct Answer: C
Question 50
What can be used as 'target-address' in the simple queue?
Correct Answer: D
In MikroTik's Simple Queues, the target-address field is used to define the IP address of the device (host) to which the queue will apply. This must be an IP address - not a MAC address or an address list name. Let's evaluate: * A.#MAC address is not supported as target-address in simple queues * B.#"server's address" is vague; if it means an IP, then it could work, but the best answer is "client's address" * C.#Address lists can be used in firewall and mangle rules, but not directly in simple queues * D.#Correct - An individual IP address (like 192.168.1.100) can be assigned as the target-address MTCNA Course Manual - Simple Queue Structure: "Use the target-address field to apply a queue to a specific host by IP." Rene Meneses Guide - Queue Setup: "Only IP addresses can be used as targets in simple queues. Address lists are not accepted." Terry Combs Notes - Bandwidth Limiting: "Target-address = device IP. MACs and lists are not allowed here."
