Your network contains an Active Directory domain named contoso.com.
The domain contains a server named SERVER1 that runs Windows Server 2012.
SERVER1 has the IP Address Management (IPAM) Serverfeature installed.
IPAM is configured currently for Group Policy-basedprovisioning.
You need to change the IPAM provisioning method on SERVER1.
What should you do?
A.
Run the ipamgc.exe command.
B.
Run the Set-IPAMConfiguration cmdlet.
C.
Reinstall the IP Address Management (IPAM) Serverfeature.
D.
Delete IPAM Group Policy objects (GPOs) from the domain.
Explanation:
You cannot change the provisioning method after completing the initial setup.
you could only go from manual to auto(group policy) not vice versa.
Provided answer is correct, but even if you choose manual and you then want to change to GP Based, you have to reinstall the feature:
“The choice of a provisioning method is permanent for the current installation of IPAM Server. To change the provisioning method, you must uninstall and reinstall IPAM Server.”
