Which set of MikroTik commands configures a DHCP server for subnet 192.168.88.0/24 on interface bridge-LAN with a pool 192.168.88.100-192.168.88.200?

• A. /ip pool add name=LAN_POOL ranges=192.168.88.100-192.168.88.200; /ip dhcp-server add name=LAN_DHCP interface=bridge-LAN address-pool=LAN_POOL authoritative=yes; /ip dhcp-server network add address=192.168.88.0/24 gateway=192.168.88.1
• B. /ip pool add name=LAN_POOL ranges=192.168.88.100-192.168.88.150; /ip dhcp-server add name=LAN_DHCP interface=bridge-LAN address-pool=LAN_POOL authoritative=yes; /ip dhcp-server network add address=192.168.88.0/24 gateway=192.168.88.1
• C. /ip pool add name=LAN_POOL ranges=192.168.88.100-192.168.88.200; /ip dhcp-server add name=LAN_DHCP interface=bridge-LAN address-pool=LAN_POOL
• D. /ip pool add name=LAN_POOL ranges=192.168.88.100-192.168.88.200; /ip dhcp-server add name=LAN_DHCP interface=bridge-LAN address-pool=LAN_POOL authoritative=yes; /ip dhcp-server network add address=192.168.88.0/24 gateway=192.168.88.254

Answer: (D)

Configuring a DHCP server on MikroTik requires three pieces: a pool of IPs to hand out, the DHCP server bound to the correct interface using that pool, and a network definition that tells clients which subnet they’re on and what gateway to use.

The pool creates the available addresses 192.168.88.100 through 192.168.88.200, ensuring leases come from the requested range. The DHCP server is attached to the bridge-LAN interface and uses that pool, so clients on that interface will receive addresses from 192.168.88.100–192.168.88.200. Marking the server as authoritative makes the MikroTik actively respond to DHCP requests for this subnet. Finally, the network entry specifies the subnet 192.168.88.0/24 and designates the gateway within that subnet (192.168.88.254 in this setup), so clients know where to send their traffic by default.

This combination is the most complete for the given requirements because it properly ties together the exact lease range, the correct interface, and a valid gateway in the same subnet, ensuring devices on bridge-LAN receive a proper DHCP lease along with their default route. Other options either omit the network definition, use a different pool range, or specify a gateway that isn’t aligned with the intended router IP in the subnet.
