MikroTik MTCNA Exam With Confidence Using Practice Dumps

The /interface wireless access-list in MikroTik is used to define a set of rules that permit or deny wireless clients based on their MAC addresses and signal strength.

This list applies only to clients trying to connect to the router’s wireless interface when it is configured as an Access Point.

Let’s break down the options:

A.✅Correct – Used to allow or deny client MAC addresses and apply settings like rate limits, VLANs, etc.

B.❌That’s the role of the registration table.

C.❌Security profiles are configured separately under /interface wireless security-profiles.

D.❌Hotspot authentication is handled via /ip hotspot, not wireless access lists.

MTCNA Wireless Module – MAC Access Control:

“Access-list matches incoming clients by MAC. You can allow, deny, and apply custom settings.”

René Meneses Study Guide – Wireless Security:

“Access-list is used to explicitly permit or block clients based on their MAC address.”

Terry Combs Notes – Wireless Filtering:

“Think of access-list like a whitelist/blacklist for Wi-Fi clients.”

Answer: AQUESTION NO: 65 [Firewall]

One host on an internal network is accessing an external web page through a MikroTik router that is doing source NAT. Select the correct statement about the packets that flow from that web page to the host:

A. Packets go through the input chain

B. Packets go through the forward chain

C. Packets go through the output chain

D. Packets go through the input chain before the routing decision and after that through output chain

Answer: B

When a host on a LAN accesses a website on the internet via a MikroTik router that’s performing source NAT (e.g., masquerade), the traffic path is as follows:

From LAN host to internet → forward chain → NAT (src-nat)

From internet back to LAN host → forward chain again → connection-tracked → src-nat reversed

Since the router is only routing the packets and is not the originator or final destination, the packet passes through the forward chain.

Clarifying the options:

A.❌input chain is for packets destined to the router itself

B.✅Correct – packet is routed through the router (forwarded)

C.❌output chain is for packets originating from the router

D.❌This description applies to packets sourced by the router itself

MTCNA Course Manual – Packet Flow Diagram:

“Forward chain handles packets that are being routed through the device (not destined to or from the router itself).”

René Meneses Guide – Firewall Chains:

“For routed traffic, the forward chain is used. This includes NATed traffic between LAN and WAN.”

Terry Combs Notes – Packet Flow:

“Understand the router’s role. If it’s just forwarding, only the forward chain applies.”

The redirect action is only valid in the dstnat chain. It is used to redirect traffic to a service running on the router itself (e.g., redirecting HTTP to a local proxy server).

A.✘srcnat – Not compatible with redirect

B.✘forward – Redirect doesn’t apply in this chain

C.✔dstnat – This is the correct and only supported chain for action=redirect

Extract from Official MTCNA Course Material – NAT Actions:

“The redirect action is used within the dstnat chain to forward packets to the router’s local services.”

Extract from MikroTik Wiki – NAT Rule Actions:

“Redirect is used in dstnat chain and changes destination address to a local router IP and port.”

===========

To configure a MikroTik wireless interface as a basic access point (AP), the minimum required parameters are:

Mode → Must be set to ap-bridge or bridge

SSID → Defines the wireless network name to broadcast

Band → Determines which frequency ranges are used (e.g., 2.4GHz b/g/n or 5GHz a/n/ac)

Frequency → Specifies the actual channel used for broadcasting

Options reviewed:

A. radio name →✘Optional. A cosmetic label used to identify the radio in Winbox.

B. scan-list →✘Optional. Used to define which frequencies the interface should scan.

C.✔Required

D.✔Required

E.✔Required

F. DFS mode →✘Optional and auto-configured based on regulatory domain.

G. WDS →✘Only needed for bridging or extending networks.

Extract from Official MTCNA Course Material – Wireless Configuration:

“The minimal settings to enable an Access Point include: mode, SSID, band, and frequency. Without these, the interface won’t broadcast.”

Extract from René Meneses Study Guide – Wireless Basics:

“To turn on an AP: Set the mode to ap-bridge, define SSID, band, and frequency. Other settings are optional or advanced.”

Extract from Terry Combs Notes – Wireless Setup:

“Essential: mode, frequency, SSID, band. Others like WDS and DFS are situational.”
