MikroTik RouterOS allows DHCP administrators to modify the DHCP address pool without creating an additional DHCP server. You can simply edit or extend the address pool range, and the DHCP server will start offering those new IPs.
Therefore, it is completely possible to:
Extend the existing address pool
Exclude statically assigned IPs
Continue using the same DHCP Server instance
You do NOT need to create a second DHCP server on the same interface.
MTCNA Course Manual – DHCP Configuration:
“It is possible to expand the address-pool dynamically without adding additional DHCP servers. Just add more IPs to the pool.”
René Meneses Study Guide – DHCP Pools Section:
“You can edit the address pool associated with the DHCP server anytime to include more addresses. No need to create another server.”
Terry Combs Notes – DHCP Tips:
“Keep one DHCP server per subnet. Extend pools via IP > Pool if more IPs are needed.”
Answer: AQUESTION NO: 25 [Wireless]
In which order are the entries in Access List and Connect List processed?
A. By Signal Strength Range
B. By interface name
C. In sequence order
D. In a random order
Answer: C
MikroTik processes the entries in the Access List and Connect List in a top-down fashion —meaning that the first matching entry is the one applied. This is known as sequence order (from top to bottom).
Each rule is checked in the order it appears in the list, and once a match is found, the rest of the list is ignored for that client.
Incorrect options:
A. Signal strength is only a condition, not a sorting method
B. Interface names are part of rule conditions
D. Not random — rules are processed sequentially
MTCNA Official Training Manual – Wireless Access & Connect List:
“Rules in access-list and connect-list are checked in the order they are listed. Once a match is found, further rules are ignored.”
René Meneses Guide – Wireless Access Rules:
“Access-list is evaluated top-down. Sequence matters.”
Terry Combs MTCNA Notes – Wireless Filtering:
“Be careful with order. The first matching rule is applied — no exceptions.”
Answer: CQUESTION NO: 26 [Wireless]
During a scan, in order to see all the available wireless frequencies that are supported by the card, the following option must be selected in the wireless card's "Frequency Mode":
A. superchannel
B. regulatory domain
C. manual txpower
Answer: A
In MikroTik RouterOS, enabling the "superchannel" frequency mode allows access to all frequencies supported by the wireless chip, including those that may be outside of country-specific regulatory limits. This mode is typically used in lab testing or in regions where regulations permit.
A. superchannel →✅Correct. Enables full frequency range
B. regulatory domain → Restricts visible frequencies to region’s law
C. manual txpower → Controls power output, not frequency scanning
MTCNA Course Material – Wireless Configuration Options:
“To unlock all available wireless frequencies for scanning or connection, enable the 'superchannel' frequency mode.”
René Meneses Study Guide – Wireless Advanced Config:
“Superchannel mode shows all channels supported by the hardware. Use with caution — may violate regulations.”
Terry Combs Notes – Wireless Modes:
“Want to see hidden or extended frequencies? Use superchannel mode. Not legal in every region.”
Answer: AQUESTION NO: 27 [NAT]
It is required to make a web server on a private LAN visible on the public internet. Only the web server port should be visible to the public. Which of the following configuration steps must be met? (Select all that apply)
A. Public IP address of the web server must be installed on the NAT Router
B. In IP firewall NAT, there should be a dst-nat between the public IP of the router and the private IP of the web server
C. Connection Tracking must be enabled on NAT router
D. A route between the NAT router and the web server must exist
E. LAN address of the web server should be routable on the internet
Answer: B, C, D
To expose a web server behind a MikroTik router to the public, the following steps must be met:
B. dst-nat rule must be created to forward incoming requests (e.g., TCP port 80) to the internal web server IP →✅Required
C. Connection Tracking must be enabled, otherwise NAT rules won’t function →✅Required
D. A route between the NAT router and the web server must exist (usually a directly connected subnet) →✅Required
Incorrect Options:
A. The public IP does not need to be installed on the web server — it remains private →❌
E. Private LAN IP (like 192.168.x.x) does not need to be routable on the internet →❌
MTCNA Course Manual – NAT and Port Forwarding Section:
“To expose internal services to the public internet, use dst-nat. Ensure connection tracking is active and the server is reachable through routing.”
René Meneses Guide – NAT Configuration:
“DST-NAT forwards specific ports to internal IPs. Connection tracking is a prerequisite. LAN IPs remain private.”
Terry Combs Notes – Web Server NAT Rules:
“No need to assign public IP to server. Just configure a proper NAT rule and ensure routing exists internally.”
