What service would make IP configuration easier for an increasing number of workstations?

Using DHCP (Dynamic Host Configuration Protocol) simplifies IP configuration in environments with numerous workstations. When a network administrator employs DHCP, each device on the network can automatically obtain its IP address and other relevant network settings without manual intervention. This automation reduces the potential for errors that can occur when IP addresses are assigned statically, especially in large networks where the number of devices can frequently change.

DHCP dynamically allocates IP addresses from a defined range and keeps track of which addresses are assigned to which devices. This ensures efficient use of IP addresses and alleviates issues related to address conflicts and management overhead. As more workstations are added to the network, DHCP scales effectively by dynamically assigning addresses, making it an ideal choice for environments where the number of devices may fluctuate.

Static IP assignment would require manual configuration for each workstation, which becomes impractical and cumbersome as the number of devices increases. Router configuration plays a role in directing traffic but does not address the automation of IP address assignment itself, while DNS (Domain Name System) is primarily concerned with resolving domain names to IP addresses, not the assignment of IP addresses to devices.
