Topic 7, Contoso, Ltd Case D
Overview
Contoso, Ltd., is a manufacturing company that makes several different components that are used in
automobile production. Contoso has a main office in Detroit, a distribution center in Chicago, and
branch offices in Dallas, Atlanta, and San Diego.
The contoso.com forest and domain functional level are Windows Server 2008 R2. All servers run
Windows Server 2012 R2, and all client workstations run Windows 7 or Windows 8. Contoso uses
System Center 2012 Operations Manager and Audit Collection Services (ACS) to monitor the
environment. There is no certification authority (CA) in the environment.
Current Environment
The contoso.com domain contains the servers as shown in the following table:
Contoso sales staff travel within the United States and connect to a VPN by using mobile devices to
access the corporate network. Sales users authenticate to the VPN by using their Active Directory
usernames and passwords. The VPN solution also supports certification-based authentication.
Contoso uses an inventory system that requires manually counting products and entering that count
into a database. Contoso purchases new inventory software that supports wireless handheld scanners
and several wireless handheld scanners. The wireless handheld scanners run a third party operating
system that supports the Network Device Enrollment Service (NDES).
Business Requirements
Security
The wireless handheld scanners must use certification-based authentication to access the wireless
network.
Sales users who use mobile devices must use certification-based authentication to access the VPN.
When sales users leave the company, Contoso administrators must be able to disable their VPN access
by revoking their certificates.
Monitoring
All servers must be monitored by using System Center 2012 Operating Manager. In addition to
monitoring the Windows operating system, you must collect security logs from the CA servers by using
ACS, and monitor the services that run on the CA and Certificate Revocation List (CRL) servers, such as
certification authority and web services.
Technical Requirements
CA Hierarchy
Contoso requires a two-tier CA hierarchy. The CA hierarchy must include a stand-alone offline root and
two Active Directory-integrated issuing CAs: one for issuing certificates to domain-joined devices, and
one for issuing certificates to non-domain-joined devices by using the NDES. CRLs must be published to
two web servers: one in Detroit and one in Chicago.
Contoso has servers that run Windows Server 2012 R2 to use for the CA hierarchy. The servers are
described in the following table:
The IT security department must have the necessary permissions to manage the CA and CRL servers. A
domain group named Corp-IT Security must be used for this purpose. The IT security department users
are not domain admins.
Fault Tolerance
The servers that host the CRL must be part of a Windows Network Load Balancing (NLB) cluster. The CRL
must be available to users in all locations by using the hostname crl.contoso.com, even if one of the
underlying web servers is offline.

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 can manage VMware ESX hosts and virtual machines by using a System Center Virtual Machine
Manager (SCVMM) server.
Reason:
SCVMM automatically imports ESX hosts and virtual machines when you add the corresponding VMware
vCenter to the SCVMM server.
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:
* Assertion: true
Virtual Machine Manager (VMM) enables you to deploy and manage virtual machines and services
across multiple hypervisor platforms, including VMware ESX and ESXi hosts.
* Reason: False
When you add a vCenter Server, VMM no longer imports, merges and synchronizes the VMware tree
structure with VMM. Instead, after you add a vCenter Server, you can add selected ESX servers and
hosts to any VMM host group. Therefore, there are fewer issues with synchronization.
