Topic 4, A.Datum Corporation
Overview
A) Datum Corporation is an accounting company.
The company has a main office and two branch offices. The main office is located in Miami. The branch
offices are located in New York and Seattle.
Existing Environment
Network Infrastructure
The network contains an Active Directory domain named adatum.com. All servers run Windows Server
2008 R2. The main office has the following servers and client computers:
Two domain controllers configured as DNS servers and DHCP servers
One file server that has multiples shares
One thousand client computers that run Windows 7
Each branch office has the following servers and client computers:
One domain controller configured as a DNS server and a DHCP server
Five hundred to 800 client computers that run Windows XP
Each office has multiple subnets. The network speed of the local area network (LAN) is 1 gigabit per
second. The offices connect to each other by using a WAN link. The main office is connected to the
Internet.
Current Issues
The WAN link between the Miami office and the Seattle office is a low bandwidth link with high latency.
The link will not be replaced for another year.
Requirements
Application Requirements
The company is developing an application named App1. App1 is a multi-tier application that will be sold
as a service to customers.
Each instance of App1 is comprised of the following three tiers:
A web front end
A middle tier that uses Windows Communication Foundation (WCF)
A Microsoft SQL Server 2008 R2 database on the back endEach tier will be hosted on one or more virtual machines. Multiple tiers cannot coexist on the same
virtual machine.
When customers purchase App1, they can select from one of the following service levels:
Standard: Uses a single instance of each virtual machine required by App1. If a virtual machine
becomes unresponsive, the virtual machine must be restarted.
Enterprise: Uses multiple instances of each virtual machine required by App1 to provide highavailability and fault tolerance.
All virtual hard disk (VHD) files for App1 will be stored in a file share. The VHDs must be available if a
server fails.
You plan to deploy an application named App2. App2 is comprised of the following two tiers:
A web front end
A dedicated SQL Server 2008 R2 database on the back end
App2 will be hosted on a set of virtual machines in a Hyper-V cluster in the Miami office. The virtual
machines will use dynamic IP addresses. A copy of the App2 virtual machines will be maintained in the
Seattle office.
App2 will be used by users from a partner company named Trey Research. Trey Research has a single
Active Directory domain named treyresearch.com. Treyresearch.com contains a server that has the
Active Directory Federation Services server role and all of the Active Directory Federation Services (AD
FS) role services installed.
Planned Changes
A) Datum plans to implement the following changes:
Replace all of the servers with new servers that run Windows Server 2012.
Implement a private cloud by using Microsoft System Center 2012 to host instances of App1.
In the Miami office, deploy four new Hyper-V hosts to the perimeter network.
In the Miami office, deploy two new Hyper-V hosts to the local network.
In the Seattle office, deploy two new Hyper-V hosts.
In the Miami office, implement a System Center 2012 Configuration Manager primary site that
has all of the system roles installed.
Implement a public key infrastructure (PKI).
Notification Requirements
A) Datum identifies the following notification requirements:
Help desk tickets must be created and assigned automatically when an instance of App1
becomes unresponsive. Customers who select the Enterprise service level must receive an email notification each time
a help desk ticket for their instance of App1 is opened or closed.
Technical Requirements
A) Datum identifies the following technical requirements:
Minimize costs whenever possible.
Minimize the amount of WAN traffic
Minimize the amount of administrative effort whenever possible.
Provide the fastest possible failover for the virtual machines hosting App2.
Ensure that administrators can view a consolidated report about the software updates in all of
the offices.
Ensure that administrators in the Miami office can approve updates for the client computers in
all of the offices.
Security Requirements
A) Datum identifies the following security requirements:
An offline root certification authority (CA) must be configured.
Client computers must be issued certificates by a server in their local office.
Changes to the CA configuration settings and the CA security settings must be logged.
Client computers must be able to renew certificates automatically over the Internet.
The number of permissions and privileges assigned to users must be minimized whenever
possible.
Users from a group named Group1 must be able to create new instances of App1 in the private
cloud.
Client computers must be issued new certificates when the computers are connected to the
local network only.
The virtual machines used to host App2 must use BitLocker Drive Encryption (BitLocker).
Users from Trey Research must be able to access App2 by using their credentials from
treyresearch.com.
