How does a router identify its role as a DHCP server?

By using IP addresses
Through specific server configurations
By enabling DHCP globally
It cannot identify this role

The correct answer is: Through specific server configurations

A router identifies its role as a DHCP server primarily through specific server configurations. This involves setting up parameters like the DHCP scope, which includes the range of IP addresses that the router can assign to clients, as well as defining options such as subnet masks, default gateways, and DNS servers. These configurations essentially tell the router to function as a DHCP server, allowing it to dynamically assign IP addresses to devices on the network. Although enabling DHCP globally is part of the process, the specific configurations define how and what the router will serve to clients. The IP addresses alone do not serve as an identifying criterion for the router's role; they are rather tools and outcomes of the DHCP service itself. Thus, the correct understanding hinges on recognizing the importance of proper setup in the router's capabilities.
