Case Study: 5
Contoso Ltd
Overview
Contoso, Ltd. is a manufacturing company that has 3,000 users.
Contoso has a data center in Toronto and 20 offices across Canada. The offices connect to
each other by using a WAN link. Each office connects directly to the Internet.
Existing Environment
Active Directory Environment
The network contains an Active Directory forest named contoso.com. The forest contains a
single domain. All domain controllers run Windows Server 2012. All servers run Windows
Server 2008 R2.
Each office contains three domain controllers. Each office is configured as an Active
Directory site.
System Center 2012 Infrastructure

Contoso has a System Center 2012 infrastructure that contains 11 servers. The servers are
configured as shown in the following table.

Contoso has a private cloud named Cloud1. Cloud1 is managed by using VMM. The
following applications run in Cloud 1:
• Microsoft Exchange Server 2010
• Microsoft SharePoint Server 2010
• A custom manufacturing application named App1
The Hyper-V hosts are managed by using VMM. TOR-H01 and TOR-H02 are nodes in a
failover cluster.
The switches that are part of the network fabric are from various manufacturers and are
managed by using SNMPv3.
App1
An application named App1 is deployed from a VMM service template that consists of one
front-end web server and one back-end database server. App1 processes credit card
information.
The instance of App1 running in the data center uses two virtual machines named VM1 and
VM2. TOR-H01 hosts VM1 and VM2.
App1 is managed by using a custom management pack named MP1. The management pack
used to monitor App1 contains a distributed application diagram named App1DAD.
The service level agreement (SLA) for App1 states that App1 must be available 99 percent of
the time.
Problem Statements
Contoso identifies the following issues:
• Currently, all Operations Manager alerts are sent by email only. Database
administrators require alerts to be sent by text message. The cell phone

numbers of the database administrators are already configured in Operations
Manager.
• Administrators report that the processor performance counters for the Hyper-V
hosts display values that are lower than the actual load on the hosts.
Requirements
Business Goals
Contoso wants to minimize hardware and software costs, whenever possible.
Planned Changes
Contoso plans to add a new web server to the App1 service template. Traffic to the new web
server will be load balanced with the existing web server by using a hardware load balancer.
Technical Requirements
Contoso identifies the following technical requirements for the planned deployment:
• Automatically apply software updates issued by Microsoft to all of the HyperV hosts.
• Automatically assign incidents to administrators when a Configuration
Manager service fails.
• Ensure that the Exchange Server administrators can request that new virtual
machines be added to the Exchange Server organization by using Internet
Explorer.
• Monitor the uptime of all the Hyper-V hosts and all the virtual machines by
using Operations Manager and VMM. Performance and Resource
Optimization (PRO)-enabled management packs will be used.
• Ensure that users have a self-service portal that provides them with the ability
to back up individual virtual machines. Users must receive an email message
confirming that the backup is complete.
• Ensure that database administrators are alerted by a text message when an
error occurs on a server that they manage. The text messages should be
delivered regardless of the current network conditions.
• Network administrators report that they currently use different tools to monitor
the port status on the switches. The network administrators want to manage all
of the switches by using Operations Manager.
App1 Requirements
Contoso identifies the following requirements for App1:
• Create an object in the App1 management pack to track the SLA.
• Ensure that multiple monitoring thresholds can be used for different instances
of App1.
• Ensure that App1 complies with the Payment Card Industry Data Security
Standard (PCI DSS).

Answer: See the explanation

Explanation:
Box 1: Create an IP address pool.
Box 2: Install the provider for the hardware load balancer
Box 3: Add a hardware load balancer
Box 4: Create a Virtual IP (VIP) template
Box 5: Copy and modify the App1 service template.

Note:
*(box 1) When you create a static IP address pool for a VM network, VMM can assign static IP
addresses to Windows-based virtual machines (running on any supported hypervisor platform) that
use the VM network. By using static IP address pools, IP address management for the virtual
environment is brought within the scope of the VMM administrator.
* (Box 2, Box 3) Prerequisite for adding a Hardware Load balancer include:
You must obtain the load balancer provider from the load balancer vendor, and install the provider
on the VMM management server.
* Setting the load balancer affinity enables you to provide some control over which load balancer
will be used for a service. This is based on logical network information. VMM uses this information to
determine the valid static IP address pools that are accessible from both the load balancer and the
host group that the service tier will be deployed to.

* By adding load balancers to VMM management and by creating associated virtual IP templates
(VIP templates), users who create services can automatically provision load balancers when they
create and deploy a service.
*(box 4) A VIP template contains load-balancer-related configuration settings for a specific type of
network traffic. For example, you can create a template that specifies the load-balancing behavior
for HTTPS traffic on a specific load balancer by manufacturer and model.
* (box 5) A load balancer must be configured before you deploy a service. After a service is
deployed, you cannot add a load balancer by updating the service.
