Question
You have a server that runs Windows Server and has the DHCP Server role installed. The server has a scope named Scope! that has the following configurations:
- Address range: 192.168.0.2 to 192.168.1.255
- Mask: 255.255.254.0
- Router: 192.168.0.1
- Lease duration: 3 days
- DNS server 172.16.0.254
You have 50 Microsoft Teams Phone devices from the same vendor. All the devices have MAC addresses within the same range. You need to ensure that all the Teams Phone devices that receive a lease from Scope1 have IP addresses in the range of 192.168.1.100 to 192.168.1.200. The solution must NOT affect other DHCP clients that receive IP configurations from Scope1. What should you create?

Why each option
A DHCP policy based on MAC address criteria allows assigning a specific IP sub-range exclusively to matching devices within a scope, without changing how other clients receive addresses.
Windows Server DHCP policies evaluate incoming client requests against conditions such as MAC address, vendor class, or user class, and when matched, can direct the server to offer an IP from a defined sub-range. Because all Teams Phone devices share a common MAC address prefix from the same vendor, a policy targeting that prefix will assign IPs from 192.168.1.100-192.168.1.200 while leaving all other Scope1 clients completely unaffected.
A new scope applies to a different subnet entirely and cannot subdivide the IP address range within an existing scope to target specific clients.
A DHCP filter controls whether clients are allowed or denied a lease based on MAC address but does not influence which IP address range is offered to matching clients.
Scope options apply DNS servers, routers, or other settings uniformly to all clients within the scope and cannot restrict or redirect specific clients to a particular IP address range.
