MikroTik MTCNA Practice Test Questions Answers

The “Area” parameter is a user-defined tag in the wireless interface configuration that works with the Access List in MikroTik RouterOS. It allows grouping of clients or APs for filtering or configuration logic.

When an Access List rule includes an area name, it will only apply to devices matching that area.

Option breakdown:

A. Connect List → Incorrect. Area is not used here.

B. Access List →✔Correct. “Area” is matched directly in Access List rules.

C. None of these → Incorrect.

D. Security Profile → Incorrect. Security Profiles control authentication/encryption, not area filtering.

Extract from Official MTCNA Course Material – Wireless Access List:

"The Area field allows you to group wireless interfaces and filter clients based on Access List rules that include this tag."

Extract from Terry Combs Notes – Wireless Configuration:

“Area is a label that can be referenced in Access List rules to apply rules selectively.”

Extract from MikroTik Wiki – Wireless Access List Section:

"Area is used in Access List to assign rules based on interface groups or locations."

The TCP/IP or DoD model includes the following layers:

Application

Host-to-Host

Internet

Network Access

The Internet layer in the DoD model is responsible for logical addressing and routing — matching the function of the OSI model's Layer 3 (Network Layer), which handles IP addressing and packet forwarding.

MTCNA Course Material – TCP/IP vs OSI Model:

“The Internet layer of the TCP/IP model maps directly to the OSI’s Network Layer and is responsible for logical addressing and routing.”

René Meneses MTCNA Study Guide – Layer Mapping Table:

“TCP/IP Internet Layer = OSI Network Layer. Handles IP routing, addressing.”

Other mappings:

Application = OSI Layers 5–7

Host-to-Host = OSI Layer 4 (Transport)

Network Access = OSI Layers 1–2

Final Answer: CQUESTION NO: 114 [RouterOS Introduction – ARP]

Which of the following allows a router to respond to an ARP request that is intended for a remote host?

A. Gateway DP

B. Reverse ARP (RARP)

C. Proxy ARP

D. Inverse ARP (IARP)

Answer: C

Proxy ARP allows a router to answer ARP requests on behalf of another device. It is often used in networks where hosts don't have proper default gateways but still need to communicate with devices in different subnets.

MTCNA Course Material – ARP Types:

“Proxy ARP allows a router to respond to an ARP request for an IP address that is not on the local subnet, effectively acting as a proxy.”

René Meneses MTCNA Guide – ARP Configuration:

“Proxy ARP is useful for bridging two IP networks or for clients that do not have default gateways defined.”

MikroTik Wiki – ARP Modes:

“When Proxy ARP is enabled, the router replies to ARP requests for hosts that are not on the same subnet.”

Other options:

A: Gateway DP is not a standard term or protocol.

B: RARP maps MAC to IP — outdated and not used in this context.

D: Inverse ARP is used in Frame Relay, not Ethernet/IP networks.

Final Answer: CQUESTION NO: 115 [DHCP]

You want to implement a mechanism that automates the IP configuration, including IP address, subnet mask, default gateway, and DNS information. Which protocol will you use to accomplish this?

A. SMTP

B. SNMP

C. DHCP

D. ARP

Answer: C

DHCP (Dynamic Host Configuration Protocol) is specifically designed to assign IP configuration details automatically to clients on a network, including:

IP address

Subnet mask

Default gateway

DNS servers

MTCNA Course Material – DHCP Server Function:

“DHCP is a service that dynamically assigns IP settings to clients, removing the need for manual configuration.”

René Meneses MTCNA Study Guide – DHCP Operation:

“DHCP provides automatic configuration of network parameters including IP, mask, DNS, and gateway.”

Other options:

A: SMTP is for email

B: SNMP is for monitoring

D: ARP resolves IP-to-MAC addresses

Final Answer: CQUESTION NO: 116 [DHCP]

Which of the following describe the DHCP Discover message?

It uses FF:FF:FF:FF:FF:FF as a layer 2 broadcast.

It uses UDP as the Transport layer protocol.

It uses TCP as the Transport layer protocol.

It does not use a layer 2 destination address.

A. 1 only

B. 1 and 2

C. 3 and 4

D. 4 only

Answer: B

When a client sends a DHCP Discover message:

It does not yet have an IP address, so it sends a Layer 2 broadcast (FF:FF:FF:FF:FF:FF).

DHCP uses UDP, not TCP.

Specifically, it uses UDP port 67 (server) and 68 (client).

Layer 2 destination is broadcast — it certainly does use a Layer 2 address.

MTCNA Course Material – DHCP Process:

“The client broadcasts a DHCP Discover message to FF:FF:FF:FF:FF:FF using UDP ports 67 and 68.”

René Meneses MTCNA Study Guide – DHCP Message Types:

“DHCP uses UDP. Discovery messages are Layer 2 broadcasts to locate a DHCP server.”

MikroTik Wiki – DHCP Protocol Behavior:

“The Discover message uses UDP and broadcast MAC addressing.”

Statements:

1: True (Layer 2 broadcast)

2: True (Uses UDP)

3: False (TCP not used)

4: False (Layer 2 destination address is broadcast)

Destination NAT (dst-nat) is used to redirect packets arriving at the router to a different internal destination. It is most commonly used to allow public access to internal services such as web servers or mail servers.

You can:

Change the destination IP address (redirect to an internal host)

Change the destination port (e.g., port 8080 to port 80)

But:

C. Changing the source port is a function of src-nat, not dst-nat →❌

D. Hiding the local network from the Internet is done via masquerade or src-nat →❌

MTCNA Course Manual – NAT Section:

“Use dst-nat to forward traffic to a private host. Port translation can also be applied (e.g., from 81 to 80).”

René Meneses Study Guide – NAT Configuration:

“dst-nat changes the destination IP/port of packets arriving on a specific interface. Common use case: access to LAN services from WAN.”

Terry Combs Notes – NAT Rule Summary:

“dst-nat = port forwarding. src-nat/masquerade = hide internal addresses.”

Answer: A, BQUESTION NO: 48 [RouterOS Introduction]

Which is the default port of IP-Winbox?

A. UDP 8291

B. TCP 80

C. TCP 8291

D. TCP 8192

Answer: C

Winbox is MikroTik’s GUI-based configuration tool. It communicates with RouterOS over TCP port 8291 by default. This port is used for both IP-based Winbox connections and MAC-based sessions (in combination with layer-2 discovery protocol).

Evaluation:

A. UDP 8291 →❌Wrong protocol

B. TCP 80 →❌Used for HTTP (WebFig)

C. TCP 8291 →✅Correct default Winbox port

D. TCP 8192 →❌Invalid / non-standard

MTCNA Course Manual – RouterOS Management Tools:

“Winbox uses TCP port 8291 by default. It is possible to change this port in the /ip service settings.”

René Meneses MTCNA Guide – Winbox Access:

“Default access via TCP 8291. Check firewall filters to ensure it’s not blocked.”

Terry Combs Notes – Remote Management:

“Winbox = TCP/8291. WebFig = TCP/80 or 443.”

Answer: CQUESTION NO: 49 [PPP]

It is possible to create an encrypted PPPoE tunnel in RouterOS:

A. true

B. false

Answer: B

PPPoE (Point-to-Point Protocol over Ethernet) does not include encryption by default. It can authenticate users using PAP or CHAP, but the data payload is transmitted in cleartext unless another secure tunneling protocol (e.g., IPSec) is layered on top.

MikroTik supports encryption in other tunneling protocols, such as:

SSTP (uses SSL)

L2TP with IPSec

OpenVPN (SSL-based)

IPsec itself (for IP layer encryption)

MTCNA Tunneling Chapter – PPP Protocol Features:

“PPPoE offers authentication, compression, but no native encryption. Use IPSec if encryption is needed.”

René Meneses Guide – Tunnel Comparison Table:

“PPPoE is not encrypted. SSTP and L2TP/IPSec are alternatives when encryption is a requirement.”

Terry Combs Notes – PPP Family Summary:

“PPPoE: Authentication = Yes, Encryption = No. Use with caution over untrusted networks.”

Answer: BQUESTION NO: 50 [Wireless]

Why is it useful to set a Radio Name on the radio interface?

A. To identify a station in a list of connected clients

B. To identify a station in Neighbor discovery

C. To identify a station in the Access List

Answer: A

The Radio Name is a human-readable identifier assigned to a wireless interface. It becomes visible in the Registration Table (i.e., the list of connected clients) on an access point. It helps network administrators distinguish between multiple connected devices.

Evaluation:

A.✅Correct — Radio Name is shown in the Registration Table (list of connected clients)

B.❌Neighbor discovery uses MAC and device identity, not radio name

C.❌Access List uses MAC addresses, not radio name, for matching

MTCNA Wireless Module – Interface Settings:

“Radio Name is shown in the registration table on the AP. It helps in client identification.”

René Meneses Guide – Wireless Monitoring:

“The AP uses the client’s Radio Name to label them in the list of associated stations.”

Terry Combs Notes – Best Practice:

“Set radio-name so you can easily tell which device is which in the registration list.”

Answer: A

In MikroTik’s firewall, the correct chain depends on the traffic direction and whether the traffic is destined for or originating from the router itself.

To block access to MSN (or any other service being accessed by a user from the LAN to the Internet), you must filter transit traffic. This is done in the forward chain.

A. input → Used for traffic destined to the router (e.g., WinBox, SSH).

B.✘process → Invalid option (does not exist in RouterOS).

C.✔forward → Used for user traffic passing through the router (e.g., LAN client to MSN servers on the Internet).

D. output → Used for traffic originating from the router itself (e.g., ping from router to external IP).

Extract from Official MTCNA Course Material – Firewall Chains:

“Use the forward chain to filter traffic passing through the router (LAN to WAN). Blocking access to external services like Facebook or MSN belongs here.”

Extract from René Meneses MTCNA Study Guide – Firewall Chains:

“To block Internet services for users, configure rules in the forward chain. Input is only for traffic targeting the router.”

Extract from MikroTik Wiki – Firewall Overview:

“forward: filters all traffic going through the router. For user access restrictions, place rules here.”

Winbox is a small, native Windows utility provided by MikroTik for graphical administration of RouterOS devices. It is typically downloaded from MikroTik's official website.

A. Router’s webpage → Incorrect. While the router’s WebFig interface may allow configuration, it does not offer a Winbox download.

B. Files menu → Incorrect. The Files menu is for storing backups or firmware packages, not distributing Winbox.

C. Console cable → Incorrect. Console access is CLI only; no GUI utilities can be transferred through it.

D. mikrotik.com → Correct. The only official and secure location to download Winbox is the MikroTik website.

Extract from Official MTCNA Course Material – RouterOS Introduction:

“Winbox can be downloaded from the official MikroTik website. It provides a GUI frontend for managing RouterOS.”

Extract from René Meneses MTCNA Study Guide – RouterOS Access Methods:

“You can download Winbox from mikrotik.com under the Software Tools section.”

Extract from Terry Combs MTCNA Notes – Access Methods:

“Winbox is a Windows application that must be downloaded from MikroTik’s website. It is not available directly from the router.”
