Create DHCP Reservation for Servers
Question
Your network contains an Active Directory Domain Services (AD DS) domain. The domain contains 10 servers that run Windows Server. The servers have static
IP addresses.
You plan to use DHCP to assign IP addresses to the servers.
You need to ensure that each server always receives the same IP address.
Which type of identifier should you use to create a DHCP reservation for each server?

https://docs.microsoft.com/en-us/powershell/module/dhcpserver/add-dhcpserverv4reservation?view=windowsserver2022-psTo ensure that each server always receives the same IP address from DHCP, you can create DHCP reservations for each server using a unique identifier. The identifier you choose should be unique to each server and not subject to change.
Out of the options provided, the most suitable identifier to use for DHCP reservations is the Media Access Control (MAC) address (option B).
The MAC address is a unique hardware identifier assigned to each network interface controller (NIC) in a device. This address is hardcoded into the device and remains constant, even if the device is moved to a different network. Using the MAC address as the identifier for the DHCP reservation ensures that the server always receives the same IP address regardless of the network it's connected to.
Option A, NetBIOS name, is a name assigned to a device for identifying it on the network. NetBIOS names can change over time, and two devices could have the same name, which makes them an unsuitable identifier for DHCP reservations.
Option C, fully qualified domain name (FQDN), is a hierarchical domain name that specifies the exact location of a device in the DNS namespace. FQDNs can also change over time, making them an unsuitable identifier for DHCP reservations.
Option D, universally unique identifier (UUID), is a 128-bit value used to identify information in computer systems. While UUIDs are unique and persistent, they are not commonly used as an identifier for DHCP reservations. Additionally, obtaining the UUID for each server may require additional configuration or software.
