question

You have a network with 50 workstations. You want to automatically configure workstations with the IP address, subnet mask, and default gateway values. Which device should you use?

answer

DHCP Server.

question

You are implementing a DHCP server for your segment. Your segment's IP address is 192.168.1.0. Your default gateway address is 192.168.1.254. Your DNS server address is 192.168.1.1.
