The best way to transfer only the firewall filter rules is to use the export command for just that section:

Command:

/ip firewall filter export

This produces a readable script containing only the firewall filter rules. This method is safer than editing binary backups and more efficient than exporting the global configuration and deleting unrelated parts.

Evaluation:

A.✅Correct – clean and script-based approach

B.❌You cannot selectively back up just firewall rules using the backup function (it’s system-wide)

C.❌Editing a backup file is not recommended and often not possible (it’s binary)

D.❌Too cumbersome and error-prone

MTCNA Course Manual – Configuration Transfer:

“Use export to get script output of specific sections. Backups are for full system restore.”

René Meneses Guide – Migrating Configurations:

“Export is recommended for transferring specific configurations like firewall rules.”

Terry Combs Notes – Export vs Backup:

“Backups = full system. Use export for clean, readable configuration transfer.”

Answer: AQUESTION NO: 79 [DHCP]

How many DHCP servers can be configured per interface on RouterOS?

A. Five

B. One

C. Two

D. Unlimited

Answer: B

RouterOS allows only one DHCP server instance per interface. If you attempt to assign more than one DHCP server to the same interface, RouterOS will throw an error.

If you need to serve multiple subnets or ranges, this must be done on different interfaces or by configuring DHCP relay or advanced routing.

MTCNA DHCP Module – Server Configuration:

“One DHCP server per interface is allowed. Assigning multiple servers to a single interface is not supported.”

René Meneses Study Guide – DHCP Design:

“Plan carefully: one server per interface. Use DHCP relay if multiple scopes are needed.”

Terry Combs Notes – DHCP Server Behavior:

“Trying to configure two servers on the same port results in failure.”
