MikroTik Certified Network Associate Exam Sample Questions (Q59-Q64):

NEW QUESTION # 59
If a packet comes to a router and starts a new, previously unseen connection, which connection state would be applied to it?

A. invalid
B. new
C. established
D. unknown
E. no connection state would be applied to such packet

Answer: B

Explanation:
MikroTik uses connection tracking to assign states to packets that pass through the router's firewall. When a packet initiates a connection that is not previously tracked, it is marked as new.
Connection states:
* new: First packet of a new connection
* established: Part of an existing tracked connection
* related: New connection related to an existing one (e.g., FTP data channel)
* invalid: Unrecognized or malformed connection
* unknown: Used in very specific or rare circumstances (not common in IP-based networks) Therefore:
* A.#Incorrect - All packets entering the firewall are tracked
* B.#Correct - This is a new connection
* C.#Incorrect - "unknown" is not used for typical traffic
* D.#Incorrect - Not invalid unless malformed or contextless
* E.#Incorrect - This is not an existing connection
Extract from Official MTCNA Course Material - Firewall Connection States:
"A packet that begins a new connection is marked as 'new'. Connection tracking then continues monitoring that session." Extract from Rene Meneses MTCNA Study Guide - Connection Tracking:
"New connections receive the 'new' state. Firewall rules often start by permitting or blocking 'new' and
'established' states."
Extract from MikroTik Wiki - Firewall and Connection States:
"State=new is assigned when no existing connection entry matches the incoming packet."

NEW QUESTION # 60
Mark all correct answers.

A. The only way to prevent wireless clients connections - disable wireless interface
B. Wireless access-list could allow and deny connect to your AP
C. Default-Forwarding could be enabled for a specific clients by wireless access-list
D. /ip firewall filter allows to deny authentication to AP

Answer: B,C

Explanation:
Let's evaluate each statement:
* A.#Incorrect - /ip firewall filter can block traffic after association/authentication but cannot directly prevent wireless authentication. Association happens before IP-level filtering.
* B.#Correct - Wireless access-list allows or denies associations based on MAC address and other parameters (signal strength, etc.).
* C.#Correct - Access-list rules can enable/disable default-forwarding per client (overriding global setting).
* D.#Incorrect - Disabling the wireless interface is not the only way. You can use access-list or disable SSID broadcast.
Extract from MTCNA Course Material - Wireless Access List:
"Access List provides client control based on MAC address. You can accept, reject, and even override default- forwarding per client." Extract from Rene Meneses MTCNA Study Guide - Access Control:
"Wireless Access List can selectively allow or deny clients and enforce individual settings like forwarding." Extract from MikroTik Wiki - Wireless Access List:
"The firewall filter is not involved in authentication. Access control must be done at the wireless layer using access-lists."

NEW QUESTION # 61
Please select valid scan-list values in interface wireless configuration:

A. default,5560,5600,5660-5700
B. 5540,5560,5620+5700
C. 5640~5680
D. 5560,5620-5700

Answer: A,D

NEW QUESTION # 62
Select valid subnet masks:

A. 255.192.0.0
B. 192.0.0.0
C. 255.255.224.0
D. 255.255.192.255

Answer: C

Explanation:
Subnet masks are used in IP networking to define the boundary between the network portion and the host portion of an IP address. A valid subnet mask must consist of a contiguous block of 1s followed by a contiguous block of 0s in its binary representation.
Let's analyze the given options:
* A. 255.192.0.0- This isnot a standard or valid subnet maskbecause the 1s are not contiguous beyond the second octet. This is typically used in class A subnetting but is not commonly considered valid in CIDR or MTCNA context. While technically binary-valid, it's not recommended or standard for practical subnetting.
* B. 255.255.192.255-Invalid, because the last octet is255, which implies all bits are 1s, but in the third octet only partial bits are set (192is11000000). This breaks the required rule of contiguous 1s followed by contiguous 0s.
* C. 192.0.0.0-Invalid, as it doesn't represent a valid subnet mask.192in the first octet (11000000) followed by zeros is not a valid mask - it's actually a network address, not a subnet mask.
* D. 255.255.224.0-Valid subnet mask. This represents/19in CIDR notation. In binary:
11111111.11111111.11100000.00000000, which follows the correct rule of contiguous 1s followed by contiguous 0s.
Extract from MTCNA Study Guide by Rene Meneses:
Subnet masks must be a continuous string of 1s followed by a continuous string of 0s. Any deviation or split between the blocks renders the mask invalid.
Extract from MTCNA Official Course Manual:
Valid subnet masks include values such as 255.0.0.0 (/8), 255.255.0.0 (/16), 255.255.255.0 (/24), and also non-classful masks like 255.255.224.0 (/19) are allowed and used for more flexible subnetting.
Conclusion:Option D is the only one meeting the criteria for a valid subnet mask as taught in the MTCNA curriculum.

NEW QUESTION # 63
PPP Secrets are used for:

A. L2TP clients
B. PPP clients
C. PPTP clients
D. Router users
E. IPSec clients
F. PPPoE clients

Answer: A,B,C,F

Explanation:
PPP Secrets is a user authentication mechanism used in MikroTik RouterOS for various PPP-based services.
These include:
* PPP (Point-to-Point Protocol)
* PPPoE (PPP over Ethernet)
* PPTP (Point-to-Point Tunneling Protocol)
* L2TP (Layer 2 Tunneling Protocol)
Each client authenticates with a username/password combination defined under PPP # Secrets. PPP Secrets is not used for:
* IPSec clients ##They use peer configurations and policies
* Router users (Winbox/WebFig) ##Use system # users, not PPP secrets
MTCNA PPP Chapter - Secrets Authentication:
"PPP Secrets are used for all PPP services: PPP, PPPoE, L2TP, and PPTP. It defines usernames, passwords, profiles, and IP bindings." Rene Meneses Guide - Tunnels and PPP:
"Any PPP-based tunnel uses PPP secrets for login validation. This includes local dial-in and remote VPN tunnels." Terry Combs Notes - PPP Authentication Table:
"PPP Secrets = for PPP, PPPoE, PPTP, and L2TP. Not for IPSec or Winbox."
