NEW QUESTION # 70
What does the passive command provide to dynamic routing protocols?
Answer: C
Explanation:
In dynamic routing (e.g., RIP, OSPF, EIGRP), the passive-interface command stops routingadvertisements (outgoing updates) from being sent through the specified interface. However, the router still listens for incoming routing updates.
Cisco IOS Configuration Guide - Passive Interface:
"The passive-interface command prevents routing updates from being sent on an interface, while still allowing updates to be received." Rene Meneses MTCNA Guide - Passive Mode:
"It suppresses sending routing advertisements but does not block receiving updates on that interface." Other options:
* A: Incorrect - it does not block receiving
* C: Incorrect - it applies to interfaces, not globally
* D: Also incorrect - it does not block all updates
Final answer: B

NEW QUESTION # 71
What is marked by connection-state=established matcher?
Answer: B
Explanation:
The connection-state=established matcher in MikroTik's firewall refers to packets that are part of an already active connection. These packets are neither new nor related - they are directly associated with a known connection that has been previously accepted or initiated.
MikroTik uses Connection Tracking (enabled by default) to determine the state of each packet:
* new: Packet begins a new connection (e.g., TCP SYN)
* established: Packet belongs to a previously established connection (reply or subsequent packets)
* related: Packet is not part of the connection, but is related (e.g., FTP data channel)
* invalid: Packet that does not match any known or valid connection
Therefore:
* A.#Correct. "Established" means part of an ongoing, known connection.
* B.#This describes "related"
* C.#This describes "invalid"
* D.#This describes "new"
MTCNA Course Manual - Firewall and Connection Tracking:
"Established - Packet that belongs to an existing connection. This includes replies and ongoing streams." Rene Meneses Study Guide - Firewall Fundamentals:
"Use connection-state=established to allow traffic that is part of previously accepted sessions." Terry Combs Notes - Connection States:
"Established = trusted, ongoing session. Essential for return traffic."

Answer: A
NEW QUESTION # 73
Firewall NAT rules process only the first packet of each connection.
Answer: A
Explanation:
MikroTik's NAT (Network Address Translation) is part of the connection tracking mechanism. NAT rules are applied only to the first packet of a connection. Subsequent packets belonging to the same connection are automatically handled by the connection tracking module using the same translation mappings established by that first packet.
Option Analysis:
* A.#True - NAT is evaluated only on the first packet of a new connection.
* B.#False - Subsequent packets are not re-evaluated against NAT rules.
Extract from Official MTCNA Course Material - Firewall & NAT Section:
"NAT rules apply to the first packet in a connection. After that, RouterOS uses the tracked connection entry." Extract from Rene Meneses MTCNA Study Guide - NAT & Firewall Concepts:
"Once the initial packet matches a NAT rule, connection tracking applies it to the whole session." Extract from MikroTik Wiki - NAT Implementation:
"NAT is evaluated on the first packet. Other packets in the same connection follow the established NAT mapping."
NEW QUESTION # 74
Which protocol does DHCP use at the Transport layer?
Answer: B
Explanation:
DHCP (Dynamic Host Configuration Protocol) operates over UDP:
* Client uses UDP port 68
* Server uses UDP port 67
It is a connectionless protocol, and because clients typically do not yet have IP addresses, UDP is used due to its simplicity.
MTCNA Course Material - DHCP Protocol Layering:
"DHCP uses UDP for communication between clients and servers. TCP is not used due to the stateless, broadcast nature of DHCP discovery." Rene Meneses MTCNA Study Guide - Port Assignments:
"UDP 67/68 are used by DHCP. TCP is not used because clients lack IPs initially." Other options:
* A: IP is the network layer, not transport
* B: TCP is used by reliable services (FTP, HTTP)
* D: ARP resolves IP-to-MAC; unrelated to DHCP transport
