What should you configure?

You manage a server infrastructure for a software development company. There are 30 physical servers
distributed across 4 subnets, and one Microsoft Hyper-V cluster that can run up to 100 virtual machines
(VMs). You configure the servers to receive the IP address from a DHCP server named SERVER1 that runs
Microsoft Windows Server 2012 R2. You assign a 30-day duration to all DHCP leases.
Developers create VMs in the environment to test new software. They may create VMs several times
each week.
Developers report that some new VMs cannot acquire IP address. You observe that the DHCP scope is
full and delete non-existent devices manually. All physical servers must keep their current DHCP lease
configuration.You need to ensure that the DHCP lease duration for VMs is 8 hours.
What should you configure?

A.
4 server-level Allow filters

B.
1 server-level DHCP policy

C.
1 scope-level DHCP policy

D.
4 scope-level exclusion ranges

Explanation:
We should use a server level DHCP policy as they apply to all DHCP clients.
Note: Polices can apply at the server level or the scope level. Server level policies are processed for all
DHCP client requests received by the server. Scope level policies are processed only for DHCP client
requests that apply to a specific scope.
