Case Study: 4
Litware, Inc
Overview
Litware, Inc. is a manufacturing company. Litware has a large data center and several offices.
Existing Environment
Network Infrastructure
The network contains a third-party network management device that supports SNMPv3. The
network contains network devices that support ICMP and SNMP and other devices that
support SNMP only.
A group named Network Technicians contains the user accounts for the support technicians
who manage all of the network servers. The support technicians regularly install updates on
the network servers.
System Center 2012 Infrastructure
Litware has all of the System Center 2012 components installed in the data centers. Service
Manager is integrated with Configuration Manager and Operations Manager.
The System Center 2012 Monitoring Pack for UNIX and Linux Operating Systems is
installed on the Operations Manager servers.
Software updates are deployed by using Windows Server Update Services (WSUS) and
Configuration Manager.
Virtualization Infrastructure
Litware has 30 Hyper-V hosts that run Windows Server 2008 R2. The Hyper-V hosts are
members of failover clusters.
Each office contains two virtual machines that run Microsoft SQL Server 2008 R2. The
virtual machines are configured in a failover cluster.
You have 100 virtual machines that run the following operating systems:
• Windows Server 2012
• Windows Server 2008 R2
• Windows Server 2003 R2
• Red Hat Enterprise Linux 6
• SUSE Linux Enterprise Server 11
Application Infrastructure
Litware has a distributed application named App1 that is installed on several virtual
machines.
The failover clusters host the databases used by App1. The components of App1 are in a
service template and a distributed application design.
Several other applications are installed on dedicated application servers. The application
servers are deployed as virtual machines.
Problem Statements
Litware identifies the following issues:
• The primary service of App1, named App1Service, hangs frequently and logs
events in the application log on theserver where ApplService fails.
• A recent security audit discovers that servers are vulnerable to attack due to
misconfigurations of the operating system.
Requirements
Planned Changes
Litware plans to implement the following changes:
• Replace the third-party network monitoring solution by using a System Center
2012 solution. The System Center 2012 solution must monitor all of the
devices monitored by the third-party solution and must discover new devices.
• On all of the virtual machines that have App1 installed, update App1 to a new
version.
Technical Requirements
Litware identifies the following technical requirements:
• Application administrators must be able to back up and restore their respective
application servers. Each server must be backed up at a different time.
• All virtual machines must be deployed by using virtual machine templates.
The templates must be prepared by using Sysprep.
• All resolved Service Manager incidents must close automatically after 72
hours.
Availability Requirements
Litware identifies the following availability requirements:
• Each request by a support technician to place a server in maintenance mode
must be approved by a network administrator.
• App1 must have 99.99 percent availability.
###EndCaseStudy###
You deploy a new virtual machine named VM29 for App1.
You view VM29 from the Operations Manager console.
You discover that VM29 is not visible when viewing the health of App1.
You need to ensure that VM29 is visible when viewing the health of App1.
What should you do?
A.
Edit the application monitoring rules.
B.
Run a network devices discovery rule.
C.
Run an Active Directory server discovery rule.
D.
Edit the distributed application design.
