Question 1 1.1 You are the administrator for your company network. You and a colleague are discussing client reservations. With client reservations, you can reserve an IP address for permanent use by a DHCP client. Typically, you will need to do this if the client uses an IP address that was assigned using another method for TCP/IP configuration. If you are reserving an IP address for a new client, or an address that is different from its current one, you should verify that the address has not already been leased by the DHCP server. Reserving an IP address in a scope does not automatically force a client currently using that address to stop using it. So, what ipconfig command would you use if the address is already in use?
