A company has a single-forest and single Active Directory Domain Services (AD DS) domain named
Fabrikam.com that runs Windows 2012 Server. The AD DS forest functional level and the domain
functional level are both set to Windows 2008 R2. You use IP Address Management (IPAM) as the IP
management solution. You have two DHCP Servers named DHCP1 and DHCP2, and one IPAM server
named IPAM1.
The company plans to acquire a company named Contoso, Ltd., which has a single-forest and singledomain AD DS named contoso.com. The forest functional level and domain functional level of
Contoso.com is set to Windows 2008. All servers at Contoso run Windows Server 2008. The IP
management solution at Contoso is based on a single DHCP server named SERVER3.
The total number of users in both companies will be 5000.
You have the following requirements:
The solution must be able to allocate up to three IP addresses per user.
All IP address leases must be renewed every two days.
You need to ensure that the corresponding servers will have enough capacity to store six years of IP
utilization data and eight months of event catalog data.
What should you recommend?
A.
Add at least 20 GB of storage to the IPAM server.
B.
Migrate Contoso.com to Fabrikam.com.
C.
Establish a forest trust between Contoso.com and Fabrikam.com.
D.
Upgrade SERVER3 to Windows Server 2012.
Explanation:
You can use IPAM to manage DHCP servers running on Windows Server 2008 R2 and above. Here
Server3 is running Windows 2008 however, so it needs to be upgraded.

I agree with the reason given but a weird thing about this question is that it reads to me that there’s no IPAM set up in the Contoso forest. IPAM in 2012 can’t work across forests and I can’t see where it says an IPAM is built in Contoso. So that would imply that Contoso has to be migrated to Fabrikam as well.
“An IPAM server provides support for a single Active Directory forest. Multi-forest topologies are not supported.” https://technet.microsoft.com/en-us/library/jj878312(v=ws.11).aspx
About disk capacity, I had a quick look at https://technet.microsoft.com/en-us/library/jj878312(v=ws.11).aspx#capacity and got the impression that single figures of GB were needed, but it was very boring so I only had a quick look!

Be careful on this question. Yes, the given answer is correct, but answer A will be tempting to select. 10,000 users will use about 1GB per month of storage. If you want to retain 6 years of data, as explained in the situation, you’ll need to have a minimum of (1*6*12 =) 78GB of disk space. So option A, to add 20GB, will be tempting to answer — but it’s wrong. That will only give you 50GB. Still not enough to have all the data required which means it’s a wrong answer for this question.

IPAM specifications
IPAM Server has the following specifications:
The scope of IPAM server discovery is limited to a single Active Directory forest. The forest itself may be comprised of a mix of trusted and untrusted domains.
IPAM supports only Microsoft domain controllers, DHCP, DNS, and NPS servers running Windows Server® 2008 and above.
DHCP operational event auditing is supported for DHCP servers running Windows Server® 2008 R2 and above.

we need to save 8 months of Event Catalog Data. IPAM can only retrieve that information from 2008 R2 (and later) DHCP servers.
but this question is weird since IPAM in Windows 2012 cannot work cross-forest.

I believe the given answer is correct. Other users here are also correct, IPAM 2012 does not support cross forest. However, the start to fixing that situation is to upgrade server 3 to 2012 – this will at least allow it to be managed by IPAM. You could then potentially install IPAM on server 3 for contoso.

I know the wording is tricky but I don’t see anywhere that says both forests need to be managed by one IPAM server.
Since clearly you can’t manage cross forest DHCP from one server, I don’t think the question is asking for that.
Therefore, you will need to Upgrade server 3 to 2012.
