Question 11

To connect your MikroTik router to a wireless access point, you have to:

Correct Answer: A,C
To establish a wireless client connection to an access point:
* The SSID must match exactly - including capitalization.
* The Band must be compatible - i.e., both devices must support and use the same frequency band (2.4 GHz or 5GHz).
* Radio Name is an identifier for display purposes only and does not affect connectivity.
Option Analysis:
* A.#Required - Matching SSID is essential.
* B.#Not Required - Radio Name is just a display label in tools like Winbox.
* C.#Required - Band compatibility is critical to ensure the device can "see" and connect to the AP.
Extract from Official MTCNA Course Material - Wireless Client Configuration:
"To connect to an AP, the client must use the same SSID and operate on a compatible band and frequency." Extract from Rene Meneses MTCNA Study Guide - Wireless Modes:
"SSID and band must match to connect. Radio name is not used in the authentication or association process." Extract from Terry Combs Notes - Wireless Settings:
"SSID is like the network name, and it must be identical. Mismatched bands (e.g., 2.4 vs 5GHz) will prevent discovery."

Question 12

In MikroTik RouterOS, Layer 3 communication between 2 hosts can be achieved by using an address subnet of:

Correct Answer: A
In traditional IPv4 subnetting, a /30 is often used to connect two hosts directly, giving two usable IPs.
However, MikroTik RouterOS (and as per RFC 3021) supports the use of /31 subnet masks for point-to-point links. A /31 provides exactly two IP addresses - which are both usable - and is ideal for conserving IP space on router-to-router links.
Subnet details for /31:
* Total addresses: 2
* Usable addresses: 2 (both can be assigned to endpoints, no broadcast) Evaluation:
* A. /31 ##Supported by MikroTik for point-to-point links (2 hosts only)
* B. /29 # Provides 6 usable IPs; more than needed for 2 hosts
* C. /32 # Single host only; no communication possible with second device
* D. /30 # Valid, but less efficient than /31
MTCNA Course Manual - IP Addressing and Point-to-Point Communication:
"MikroTik RouterOS allows the use of /31 subnets for point-to-point communication. Both IPs are usable." Rene Meneses MTCNA Guide - IP & Routing Concepts:
"For links between exactly two devices, /31 saves address space and is supported by MikroTik." Terry Combs Notes - Subnet Efficiency:
"Use /30 or /31 for point-to-point links. MikroTik supports /31 fully, unlike older systems."
insert code

Question 13

What menus should be used to allow certain websites to be accessed from behind a Hot-Spot interface, without client authentication?

Correct Answer: C,D
MikroTik's Hotspot feature intercepts all HTTP requests and redirects them to a login page. However, there are use cases where unauthenticated users need access to certain websites (e.g., public resources or captive portal exceptions). In such cases, MikroTik uses the "Walled Garden" feature.
There are two types of Walled Garden:
* C. ip hotspot walled-garden: used for allowing access to domain names or web addresses (e.g.,www.
example.com)
* D. ip hotspot walled-garden ip: used for allowing access to specific IP addresses, bypassing authentication
* A. ip-binding # Incorrect. This allows bypass or blocking based on IP/MAC of the user, not websites
* B. profile # Incorrect. This is used for setting Hotspot server configurations
* C.#Correct-used for domain-based exemptions
* D.#Correct-used for IP-based exemptions
Extract from Official MTCNA Course Material - Hotspot Section:
"Walled-Garden allows specific websites or IP addresses to be accessible without login. This is useful for allowing access to a captive portal or other resources." Extract from Rene Meneses MTCNA Study Guide - Hotspot Chapter:
"Use the walled-garden or walled-garden ip menus to permit pre-login access to public or portal URLs." Extract from Terry Combs Notes - Hotspot Walled Garden:
"Walled-garden (by domain) and walled-garden IP (by destination IP) let clients bypass the login page for specific services."
insert code

Question 14

What is the default TTL (time to live) on a router that an IP packet can experience before it will be discarded?

Correct Answer: D
TTL (Time to Live) is a field in the IP header that limits the number of hops a packet can travel. Each router that processes the packet decrements the TTL by 1. When TTL reaches 0, the packet is dropped.
Default TTL values vary by operating system, but in RouterOS and many Linux-based systems, the default TTL is 64.
* A. 60 # Incorrect, used in some systems but not the MikroTik default
* B. 30 # Incorrect
* C. 1 # Incorrect; would allow only one hop
* D. 64 ##Correct
Extract from Official MTCNA Course Material - TTL Field Explanation:
"The default TTL in RouterOS and most Unix-like systems is 64. Each router decrements this by 1 until the packet is discarded." Extract from Rene Meneses Study Guide - IP Protocol Details:
"TTL is initialized to 64 by default in MikroTik RouterOS."
Extract from MikroTik Wiki - IP Protocol Section:
"RouterOS sets default TTL of 64 unless manually configured otherwise."
insert code

Question 15

MikroTik RouterOS is sending logs to an external syslog server. Which protocol and port is used by RouterOS for sending logs (by default)?

Correct Answer: A
RouterOS uses the industry-standard syslog protocol for remote logging. By default, syslog uses UDP port
514.
MTCNA Course Material - Logging Section:
"For sending logs to a remote syslog server, RouterOS uses the syslog protocol on UDP port 514 by default." Rene Meneses MTCNA Guide - Monitoring & Logging:
"External logging is done using UDP port 514, which is the standard syslog protocol port." MikroTik Wiki - Logging Configuration:
"To send logs to a remote server, configure an action of type remote with a remote address and use UDP port
514 unless otherwise changed."
Other ports:
* UDP 21 = FTP (not logging)
* UDP 113 = Ident protocol
* TCP 110 = POP3
Only UDP 514 is correct.
