Topic 1, ABC Engineers
Overview
ABC Engineers is a shipping, manufacturing and distribution company located in Detroit with
branch offices in Miami, Toronto, Dallas and New York.
Existing Environment Network Infrastructure
ABC Engineers network consists of a single Active Directory domain named ABC.com. ABC
Engineers network contains a File server, DNS servers, DHCP servers, Windows Server Update
Services (WSUS), SQL server and servers configured for Failover Clustering.
The ABC Engineers branch offices all contain a single DNS and DHCP server. The branch office
DHCP servers are configured with a scope for their respective office. All ABC Engineering offices
are configured as a single subnet communicating via 1 gigabit per second network speeds with
VPN connections for connecting offices and Internet access.
Current Issues
Several branch office network users started complaining about poor network transfer speeds when
copying files located on the Detroit office File server. A thorough investigation has determined that
the branch office users experience the poor network transfer speeds during times of peak network
traffic.
Planned Changes
ABC Engineers wants to have all Detroit office and branch office servers replaced with server
running Microsoft Windows Server 2012 whilst creating web-based application which access
Customer Relationship Management (CRM) databases and saves sessions to memory of the Web
servers.
ABC Engineers additionally plans deployment of Microsoft System Center and two front-end Web
servers running from virtual machines whilst monitoring and creating alerts when CRM database
availability to the Web applications is below 90 percent.
Business Requirements
ABC Engineers requires that all future growth plans minimize the cost of hardware and software
as much as possible whilst ensuring network traffic across VPNs connecting offices are kept at a
minimum. ABC Engineers wants to ensure connectivity to the Detroit office File server shares in
the event of Internet Link failures.
Technical Requirements
ABC Engineers wants the DHCP implementation highly available with the utilization of a encrypted
central database for storing all office security events. ABC Engineers Detroit office Administrators
should be the only administrators allowed managing and approving Windows Updates and third-party Updates. The
HKEY_LOCAL_MACHINE\SYSTEM\CurrintControlSet\Services\W32Time\Parameter of the
RelaibelTimeSource should be set to 1 ensuring all domain controllers time are accurate.
Virtualization Requirements
ABC Engineers wants to have administrative overhead reduced by assigning users the minimal
required permissions and privileges whilst ensuring members of a group named ABC1 are able to
add WSUS servers to the fabric. ABC Engineers additionally wants administrative effort of the
virtual infrastructure minimized and be able to generate a diagram view of the virtual environment.
ABC Engineers want you to ensure the Customer Relation Management (CRM) database is not
affected from the front-end web server whilst ensuring members of the group ABC2 are able to
create virtual machines in the Dallas office. ABC Engineers wants the System Center 2012 Virtual
Machine Manager (VMM) library objects when creating virtual machine templates whilst applying
limited distribution release (LDR) updates to the virtualization hosts without affecting other running
virtual machines.
