Your network contains an Active Directory domain named contoso.com.
The domain contains two member servers named Server1 and Server2.
You install the DHCP Server server role on Server1 and Server2.
You install the IP Address Management (IPAM) Server feature on Server1.
You notice that you cannot discover Server1 or Server2 in IPAM.
You need to ensure that you can use IPAM to discover the DHCP infrastructure.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)

A.
On Server2, create an IPv4 scope.

B.
On Server1, run the Add-IpamServerInventory cmdlet.

C.
On Server2, run the Add-DhcpServerInDc cmdlet

D.
On both Server1 and Server2, run the Add-DhcpServerv4Policy cmdlet.

E.
On Server1, uninstall the DHCP Server server role.

IPAM discovers DHCP servers that are authorized in the Active Directory domains you specify
and that respond to a DHCPInform message.

Add-DhcpServerInDC
Adds the computer running the DHCP server service to the list of authorized Dynamic Host
Configuration Protocol (DHCP) server services in Active Directory (AD).

IPAM must be installed on a domain member computer.
You cannot install IPAM on a domain controller. If IPAM is installed on the same server with
DHCP, then DHCP server discovery will be disabled.
