A network administrator is tasked with ensuring a critical server on the LAN retains a consistent address delivered by the server responsible for dynamically assigning network configurations. The server's network interface is identified by the hardware address 00-14-22-3A-CD-08. Which measure should the administrator implement to achieve the desired outcome?
Configure a scope option specific for the critical server to always receive the same network identifier.
Create a reservation on the configuration server for the unique hardware address of the critical server.
Manually set the network identifier on the critical server within the range managed by the configuration server.
Set aside a unique identifier within the configuration scope to prevent its assignment to other devices.
