Topic 6, Contoso Ltd Case C
Background
Overview
Contoso, Ltd., is a manufacturing company. The company has offices in Chicago and Seattle. Each office
contains two data centers. All of the data centers and sites for the company have network connectivity
to each other. The company uses a single Active Directory Domain Services (AD DS) domain.
Contoso is growing rapidly and needs to expand its computer infrastructure.
Current Environment Chicago Office
The Chicago office contains a primary data center and a backup data center. A Hyper-V cluster named
Clusterl.contoso.com resides in the primary data center. The cluster has a multiple network path
configured. The cluster includes two unused SQL Server virtual machines (VMs) named SQL-SERVER1 and
SQL-SERVER2. The cluster also includes a Hyper-V Host group named Chi-Primary.
Clusterl.contoso.com contains the following servers:
 CHI1-HVNODE1.contoso.com
 CHI1-HVNODE2.contoso.com
 CHI1-HVNODE3.contoso.com
 CHI1-HVNODE4.contoso.com
The backup data center for the Chicago office is located on a Hyper-V cluster named
Cluster2.contoso.com. The cluster has a single network path configured. The cluster includes a Hyper-V
Host group named Chi-Backup.
Cluster2.contoso.com contains the following servers:
 CHI2-HVNODEl.contoso.com
 CHI2-HVNODE2.contoso.com
 CHI2-HVNODE3.contoso.com
 CHI2-HVNODE4.contoso.com
In addition, the Chicago office contains two standalone Hyper-V servers named CHIHVSERVER1.contoso.com and CHI-HVSERVER2.contoso.com.
There are also four newly built servers:
 CHI-SERVERl.contoso.com
 CHI-SERVER2.contoso.com CHI-SERVER3.contoso.com
 CHI-SERVER4.contoso.com
All the servers in the Chicago office run Windows Server 2012. Any future servers that are deployed in
the Chicago office must also run Windows Server 2012.
All servers in the Chicago office use the subnet 10.20.xx.
Current Environment Seattle Office
The Seattle office contains a primary data center and a backup data center. The primary data center is
located on a Hyper-V cluster named Cluster3.contoso.com. The cluster has a multiple network path
configured. The cluster includes two unused SQL Server virtual machines named SQL-SERVER3 and SQLSERVERS. The cluster includes a Hyper-V Host group named Sea-Primary.
Cluster3.contoso.com contains the following servers:
 SEA3-HVNODEl.contoso.com
 SEA3-HVNODE2.contoso.com
 SEA3-HVNODE3.contoso.com
 SEA3-HVNODE4.contoso.com
The backup data center for the Seattle office is located on a Hyper-V cluster named
Cluster4.contoso.com. The cluster has a single network path configured. The cluster includes a Hyper-V
Host group named Sea-Backup.
Cluster4.contoso.com contains the following servers:
 SEA4-HVNODEl.contoso.com
 SEA4-HVNODE2.contoso.com
 SEA4-HVNODE3.contoso.com
 SEA4-HVNODE4.contoso.com
In addition, the Seattle office contains two standalone Hyper-V servers named SEAHVSERVERl.contoso.com and SEA-HVSERVER2.contoso.com.
There are also four newly built servers:
 SEA-SERVERl.contoso.com
 SEA-SERVER2.contoso.com
 SEA-SERVER3.contoso.com
 SEA-SERVER4.contoso.comAll servers in the Seattle office run Windows Server 2012 R2. Any future servers that are deployed in the
Seattle office must also run Windows Server 2012 R2.
All servers in the Seattle office use the subnet 10.10.x.x.
Business Requirements
Apps
Contoso plans to deploy new applications to make its departments more efficient.
App1
Contoso must create a new application named App1 for the human resources (HR) department. The
infrastructure for App1 must reside in a virtual environment and the data files for App1 must reside on a
single shared disk. In addition, the infrastructure for App1 must meet the following requirements:
 maximize data protection
 withstand the loss of a single guest virtual machine
 withstand the loss of a single physical server
To support App1, Contoso must deploy a new cluster named Applcluster.contoso.com. The cluster has
the following requirements:
 It must span multiple sites.
 It must support dynamic quorums.
 It must prevent failures caused by a 50% split.
App2
Contoso must create a new application named App2. To support App2, Contoso must deploy a new SQL
Server cluster. The cluster must not be part of the domain.
The server deployment team that will install the cluster has limited permissions. The server deployment
team does not have the ability to create objects in Active Directory.
Virtualization and Storage
New VMs
Any new VMs that are deployed to the Hyper-V cluster in Cluster3.contoso.com have the following
requirements:
 New SQL Server VMs must be deployed only to odd-numbered servers in the cluster.
 All other new VM guests must be deployed to any available server in the cluster.
New VDEThe company needs a highly available file share cluster for a new Virtual Desktop Environment (VDE). It
has the following requirements:
 The file share cluster must withstand the loss of a single server.
 The file share cluster must withstand the loss of a single network path.
 The file share cluster must use the least amount of disk space.
New virtualized SQL Server cluster
Contoso must create a new application for manufacturing. The company needs a new virtualized SQL
Server cluster named VM-SQLclusterl.contoso.com. It has the following requirements:
 The cluster must use a shared virtual hard disk.
 The cluster must have two nodes named VM-SQL-NODE1.contoso.com and VM-SQLNODE2.contoso.com.
Highly available storage solution
The company is deploying new hardware that will replace the existing Hyper-V clusters. The new file
share cluster must have a highly available storage solution for a Hyper-V environment. It has the
following requirements:
 The new file share cluster must support guest VM clusters.
 The storage cannot reside on any of the physical Hyper-V hosts.

This question consists of two statements: One is named Assertion and the other is named Reason.
Both of these statements may be true; both may be false; or one may be true, while the other may be
false.
To answer this question, you must first evaluate whether each statement is true on its own. If both
statements are true, then you must evaluate whether the Reason (the second statement) correctly
explains the Assertion (the first statement). You will then select the answer from the list of answer
choices that matches your evaluation of the two statements.
Assertion:
You must install and configure Network Device Enrollment Services (NDES) on CHICA01.
Reason:
NDES allows non-domain joined devices to obtain a Certificate Revocation List from an Active Directoryintegrated certification authority, and then validate whether a certificate is valid.
Evaluate the Assertion and Reason statements and choose the correct answer option.

A.
Both the Assertion and Reason are true, and the Reason is the correct explanation for the Assertion.

B.
Both the Assertion and Reason are true, but the Reason is not the correct explanation for the
Assertion.

C.
The Assertion is true, but the Reason is false.

D.
The Assertion is false, but the Reason is true.

E.
Both the Assertion and the Reason are false.

Explanation:
The Network Device Enrollment Service (NDES) allows software on routers and other network devices
running without domain credentials to obtain certificates based on the Simple Certificate Enrollment
Protocol (SCEP).
