Which command adds a single interface port to an existing bridge named bridge1?

• A. /interface bridge port add bridge=bridge1 interface=ether1
• B. /interface bridge add name=bridge1
• C. /ip address add address=192.168.0.1/24 interface=ether1
• D. /interface bridge port add bridge=bridge2 interface=ether3

Answer: (A)

To connect a physical interface to an existing bridge in RouterOS, you add the interface as a port on that bridge using the /interface bridge port add command. You specify the existing bridge by its name and the interface you want to attach. In this case, the bridge is named bridge1 and the interface you’re adding is ether1, so you attach ether1 to bridge1 as a port. This directly accomplishes the task of adding a single interface port to the existing bridge. The other options don’t fit because they do one of the following: create a new bridge instead of adding a port to an existing one, assign an IP address to an interface (which is not about bridging), or reference a different bridge name (which would affect a different bridge, not bridge1).
