You need to ensure that you can use IPAM on Server1 to manage DNS on DC1

Your network contains an Active Directory domain named contoso.com. The domain contains a
domain controller named DC1 and a member server named Server1. Server1 has the IP Address
Management (IPAM) Server feature installed.
On Dc1, you configure Windows Firewall to allow all of the necessary inbound ports for IPAM.
On Server1, you open Server Manager as shown in the exhibit. (Click the Exhibit button.)

You need to ensure that you can use IPAM on Server1 to manage DNS on DC1.
What should you do?

A.
Modify the outbound firewall rules on Server1.

B.
Modify the inbound firewall rules on Server1.

C.
Add Server1 to the Remote Management Users group.

D.

Explanation:
To access configuration data and server event logs, the IPAM server must be a member of the
domain IPAM Users Group (IPAMUG). The IPAM server must also be a member of the Event Log
Readers security group.
Note: The computer account of the IPAM server must be a member of the Event Log Readers
security group.
