Question 7
David is a veterinarian who has a number of dairy farmers among his long-term clients. David regularly visits
clients to check on the health of their dairy cattle. For each cow, David records its milk production statistics
and makes notes for its medical record on a preprinted form. Each night he enters the data into a file on his
home computer. As David’s client base has grown, record keeping in this way has become time consuming. A
friend in another district has been using a hand-held device (Figure 1) to record data on site. He then uploads
it when he gets back to his office.
David has asked you for some advice on finding a suitable hand-held device and setting it up for his data
recording.

SECTION C – Case study
Instructions for Section C
Read the case study below and answer the following questions in the spaces provided.
WER Clothier is a clothing manufacturer that supplies many exclusive clothing stores, as well as the larger
department stores. Its computer network needs upgrading due to the extra demands of emerging technology
and the ever-growing requirements of its own staff and customers.
Customer feedback has indicated that people now want to order and pay for goods over the Internet.
The sales and marketing staff, in particular, want to better utilise their mobile technology, such as hand-held
devices and laptops used in the field. They would like to be able to connect to the network remotely using a
wireless communications connection. Utilising wireless technology would allow them to record data when
visiting the production warehouse.
The existing network infrastructure has a flat design and does not use subnets or VLANs. The network is
running on Cat 5 UTP cable as the backbone and Cat 5 UTP cable to the desktop. 24 port 10/100 switches are
also being used.
The management team has put together a two-year plan for an upgrade of the network.
The backbone cable will be upgraded to single mode fibre optic cable, connected via fibre optic switches,
running at a speed of 1 gigabit. Cat 6 UTP cable will be used for connection to the desktops. 24 port 10/100/1 Gbit
switches will be used for the desktops. These switches will have fibre optic ports to allow for connection to the
backbone. The network will be segmented by the use of subnets and VLANs.
The company has a network demilitarised zone (DMZ) to assist in Internet traffic management. A DMZ is a
computer or small sub-network that sits between a trusted (secure) internal network, such as a corporate private
LAN, and an untrusted (unsecured) external network, such as the public Internet. It is an area of the network
that has less security to allow for Internet traffic.
The WER Clothier DMZ contains the following servers that are accessible to Internet traffic.
• web server
• proxy server
• email server
• DNS server
All servers will be upgraded or replaced as necessary and will use 10/100/1 Gbit network cards, running at
1 gigabit. Desktop PCs will also be upgraded or replaced as necessary and will have 10/100/1 Gbit network
cards installed. Initially the cards will be set to run at 100 Mbit. Network printers will be installed, as well as
some network multifunction devices, such as colour capable printer/copier/scanner/fax all-in-one machines in
key locations.
You, as the network manager, and Joe, the network administrator, are now faced with the challenge of
implementing the two-year plan to provide a network that will meet current and future requirements.
The following diagrams show the existing network and the proposed new network.

A range of services for the network will originate in the DMZ. A number of servers will provide these services.
All data traffic will enter and leave via the DMZ.

Changing and allocating file and folder permissions gives you greater control over how users access and
manipulate data, files and folders. You and Joe have full control permissions. The other managers and department
administrators have ‘modify’ permissions. All other users have ‘read’ and ‘execute’ and ‘write’ permissions.
Sherry, a data entry operator in the administration department, rings the Help Desk and says that she needs to
edit some files in a folder created by Sam. When she attempts to access the folder and view the files, she gets
a message that says ‘permission denied’.
