Case Study: 3
Litware, Inc
Overview
Litware, Inc., is a manufacturing company. The company has a main office and two branch
offices. The main office is located in Seattle. The branch offices are located in Los Angeles
and Boston.
Existing Environment
Active Directory
The network contains an Active Directory forest named litwareinc.com. The forest contains a
child domain for each office. The child domains are named boston.litwareinc.com and
la.litwareinc.com. An Active Directory site exists for each office.
In each domain, all of the client computer accounts reside in an organizational unit (OU)
named AllComputers and all of the user accounts reside in an OU named AllUsers.
All domain controllers run Windows Server 2008 R2 and are configured as DNS servers.
The functional level of the domain and the forest is Windows Server 2008.
Network Infrastructure
The main office has the following servers:
• Five physical Hyper-V hosts that run Windows Server 2012
• Three virtual file servers that run Windows Server 2008 R2
• One physical DHCP server that runs Windows Server 2008 R2
• Ten physical application servers that run Windows Server 2012
• One virtual IP Address Management (IPAM) server that runs Windows Server 2012
• One virtual Windows Server Update Services (WSUS) server that runs Windows
Server 2008 R2
• One physical domain controller and two virtual domain controllers that run Windows
Server 2008 R2
Each branch office has following servers:
• One virtual file server that runs Windows Server 2008 R2
• Two physical Hyper-V hosts that run Windows Server 2012
• One physical DHCP server that runs Windows Server 2008 R2
• One physical domain controller and two virtual domain controllers that run Windows
Server 2008 R2
All of the offices have a high-speed connection to the Internet. The offices connect to each
other by using T1 leased lines.
The IPAM server in the main office gathers data from the DNS servers and the DHCP servers
in all of the offices.
Requirements
Planned Changes
The company plans to implement the following changes:
• Implement the Active Directory Recycle Bin.
• Implement Network Access Protection (NAP).
• Implement Folder Redirection in the Boston office only.
• Deploy an application named Appl to all of the users in the Boston office only.
• Migrate to IPv6 addressing on all of the servers in the Los Angeles office. Some
application servers in the Los Angeles office will have only IPv6 addresses.
Technical Requirements
The company identifies the following technical requirements:
• Minimize the amount of administrative effort whenever possible.
• Ensure that NAP with IPSec enforcement can be configured.
• Rename boston.litwareinc.com domain to bos.litwareinc.com.
• Migrate the DHCP servers from the physical servers to a virtual server that runs
Windows Server 2012.
• Ensure that the members of the Operators groups in all three domains can manage the
IPAM server from their client computer.
VPN Requirements
You plan to implement a third-party VPN server in each office. The VPN servers will be
configured as RADIUS clients. A server that runs Windows Server 2012 will perform
RADIUS authentication for all of the VPN connections.
Visualization Requirements
The company identifies the following visualization requirements:
• Virtualize the application servers.
• Ensure that the additional domain controllers for the branch offices can
be deployed by using domain controller cloning.
• Automatically distribute the new virtual machines to Hyper-V hosts
based on the current resource usage of the Hyper-V hosts.
Server Deployment Requirements
The company identifies the following requirements for the deployment of new servers on the
network:
• Deploy the new servers over the network.
• Ensure that all of the server deployments are done by using multicast.
Security Requirements
A new branch office will open in Chicago. The new branch office will have a single readonly domain controller (RODC). Confidential attributes must not be replicated to the Chicago office.

You need to recommend changes to the Active Directory site topology to support on the
company’s planned changes.
What should you include in the recommendation?
A.
A new site
B.
A new site link bridge
C.
A new site link
D.
A new subnet
Explanation:
Sites overview
Sites in AD DS represent the physical structure, or topology, of your network. AD DS uses
network topology information, which is stored in the directory as site, subnet, and site link
objects, to build the most efficient replication topology. The replication topology itself
consists of the set of connection objects that enable inbound replication from a source
domain controller to the destination domain controller that stores the connection object. The
Knowledge
Consistency Checker (KCC) creates these connection objects automatically on each domain
controller.

Given Answer is wrong, especially versus the explanation that is correct.
A: A new Site is the correct answer.

The answer should be D.
When you add the Active Directory Domain Services server role to create the first domain controller in a forest, a default site (Default-First-Site-Name) is created in AD DS. As long as this site is the only site in the directory, all domain controllers that you add to the forest are assigned to this site. However, if your forest will have multiple sites, you must create subnets that assign IP addresses to Default-First-Site-Name as well as to all additional sites.

Because Migrate to IPv6 addressing on all of the servers in the Los Angeles office. Some application servers in the Los Angeles office will have only IPv6 addresses.
So you need create a new subsite.

No, you need a new subnet for the IPv6 migration, will go under the current LA site. So, D is the answer.

Billy is correct. The question specifically references the “Planned Changes” section. That section does not mention the new office. It does mention the IPv6 transition. Since you will only have IPv6 addresses, you should remove the IPv4 subnet object and create a new IPv6 object. If you do not then AD site aware applications may not work as expected.

Hey,Banane!
A new branch office will open in Chicago.
A new site is a must!

Agree with Mark & JimiLives
An Active Directory site exists for each office…
A new branch office will open in Chicago…
Answer : A
When creating a new site, it is implied / common practice that you will then create a new subnet and assign it to the new site… even the “pop up” says something like… to complete the site, add a subnet, a DC, etc…
Simply creating a subnet allows it to be added to any existing site… therefore, the Site needs to exist or be created first…

But: “You need to recommend changes to the Active Directory site topology”
Your goal is to change site topology (create new site). True, you need new subnet to achieve that, but just creating new subnet wont change site topology.
So i belive is A.

“You need to recommend changes to the Active Directory site topology to support on the company’s PLANNED CHANGES.”
A new subnet is a topology change that meets the IPv6 migration requirement.
A new site should be created, but in a security related question.
I think the answer is D

Agree with sdquirra.

just to be clear, you can have multiple subnets in one Site.
A new subnet does not mean an new site.

Definitely, A. Chigogo is a new site. You must create a new site or there will be no control of where users access DO and other services. Don’t read to much into it. Know why you are performing the action.
