The command used to assign an IP address range to a DHCP pool is indeed focused on defining the network along with its subnet mask. Utilizing the syntax that includes both the network address and the subnet mask allows the DHCP server to understand the range of IP addresses it can assign to clients. This command effectively sets the scope of the DHCP pool by indicating which addresses are available for allocation within that specific subnet, ensuring that devices on the network can receive valid IP addresses.

In contrast, the other options do not accurately convey the correct method for specifying a DHCP pool's IP address range. While options may seem plausible, they do not follow the correct syntax or command structure that Cisco devices utilize for DHCP configuration.
