CIS3003 Assignment 2 Due date: 24 April 2017 1 May 2017 Weighting: 15% Part A: Mini Case Study (2 pages maximum) You are to provide an essay (2 (two) pages maximum) answering the following mini case question from the textbook. The essay is to be a 1.5 line spacing. The essays do not require in text references or a list of references. Computer Dynamics (textbook edition 12 page 182) Computer Dynamics is a microcomputer software development company that has a 300 + computer network. The company is located in three adjacent five-story buildings in an office park, with about 100 computers in each building. The LANs in each building are similar, but one building has the data canter on the second floor. There are no other office locations. The current network is poorly designed for its current needs and must be completely replaced. Develop a logical design for this enterprise campus that considers the seven network architecture components (layers). There are no other campuses, so you can omit WAN access. You will need to make some assumptions, so be sure to document your assumptions and explain why you have designed the network in this way. (10 marks) Part B Hands on This section is based on the activities in the Hands on exercise (5A on page 187 of the textbook edition 11) (5A on page 151 of the textbook edition 12). You will need access to a networked computer that has PING, ARP and NETSTAT tool available. For some of the activity (ping) if you have a restrictive firewall you will need to search for a Looking Glass type services and modify your report accordingly (search Google for looking glass tools). PING: (10 marks) Deliverable: • Describe the purpose of the ping command and how it operates to provide the services. If using Looking Glass tool include that in your description. • Explain if the commend is an example of Connection oriented or Connectionless service. • List and describe the purpose of the ISO layers that the ping command would need to use to provide the results. • ping your default gateway. • Explain the purpose of the gateway and how your computer was configured/discovered that information. • ping google.com. • Explain what information you the operation returned and how the information can be interpreted. • Attach a Screen Capture of the command being executed to google.com ARP: (5 marks) Deliverables. • Describe the purpose of the arp command and how it operates to provide the services. • Describe 6 of the available parameters for the command and their purpose and how they are used. • Execute the arp command and explain the information displayed on the screen. • Screen capture of the command execution on the computer. NETSTAT: (5 marks) Deliverables: • Describe the purpose of the netstat command and how it operates. • Describe 6 of the available parameters for the command and their purpose and how they are used. • List and describe why a connection could be left in ‘HALF-OPEND’ state. • Screen capture of the netstate command running. (20 marks) Part C: Business Report (10 pages max for body of the report) (For structure and marking guidelines of the report see marking guidelines document) NAS vs SAN vs CLOUD After a number of business seminars dealing with the future adoption of technologies within the business framework the theme of remotes access to business data and process for flexible customer services was identified as a limiting factor in the current infrastructure design. When the organisation started trading the networking and data management was implemented by individuals as a peer to peer solution. The limitation of this design became obvious in the early years and the organisation moved to a traditional 2 tier client server design which is still the major solution for most of the services. In order to move to a modern n-tier solutions the organisation is looking at possibility of moving to SAN or Cloud solutions. In order to move forward you have been tasked with researching and providing detailed information to management to assist in their decision making process. a) Currently the organisation data storage mechanism can be described as NAS (Network Attached Storage) solution. Research and describe NAS storage as a solution for data storage in a business network. Research and discuss any limitation in using NAS storage in organisation. b) The other option proposed is to move to a SAN (Storage Area Networks) based solution for the sharing of data. Describe the SAN based solutions and their benefits for data sharing in an organisation compared to NAS. c) If we were to adopt SAN solutions as a data store and access mechanism, discuss what changes would we have to conceder in the network infrastructure and design to get optimal use of the SAN solution. d) Cloud based solution are a consideration especially as a lot of the management can be outsourced to the provider. We have the option of using either a Private, Public or a Hybrid cloud solution. Discuss the differences of the three cloud types with respect to outsourcing the management of the operations. e) The organisation is planning on providing remote services to its employees and customers in the future. From the above research make a recommendation regarding the future use of storage solutions in the organisation. Clearly list and justify your arguments for the technology chosen.

Most traditional construction around the world is well-adapted to its environment and generally makes use of ecologically appropriate building materials and forms. Before mechanical space heating and cooling were available, traditional settlements developed a natural harmony with their climate and had as a consequence, a minimal carbon footprint. With global warming, we are returning to ecologically sustainable and climatically appropriate building designs. Particularly in this assignment, we will be looking at building designs, in climatically diverse locations across Australia and our near neighbours, investigating appropriate solutions for that location from elsewhere in the world that will have a minimum carbon footprint. You will be focusing on traditional solutions (say prior to 1900’s) from around the world, in similar climatic locations; to derive possible solutions for the location you will be assigned. As a group of 5 (minimum) or 7 (maximum) students, you will be allocated a location and your group is to become familiar with its peculiar climatic constraints. You are then to investigate other locations around the world in similar climates and discover the type of traditional building that developed to solve their particular needs for warmth (or cooling) and shelter. The list at the end of this handout has locations from around our region which are climatically diverse. When you have formed your groups a location will be allocated. Please form groups early in the semester. You must research the following topics to determine their influence on building design for your location: 1. The characteristics of the climate. i. Average maximum summer and minimum winter temperatures. ii. Diurnal temperature range both in summer and winter. iii. Humidity levels in summer and winter. iv. Solar characteristics (sun path and intensity of solar radiation). v. Atmospheric conditions (dust, cloudiness, precipitation e.g. mist & rain). vi. Incidence and extent of snow, if applicable. vii. Evaporation rates, rainfall intensities, flooding, fire and any other extremes of climatic conditions encountered at your location. viii. Remember to consider the use of vegetation to control the extremes of the climatic conditions, if at all possible. 2. Lighting needs of the building i. Glare problems; snow or bare ground. ii. Natural and artificial methods of lighting. iii. Lighting control throughout the day. 3. Acoustic background of the building i. External noise levels ii. Internal noise levels The locations chosen have some degree of discomfort in their climate in either summer or winter conditions. It might be the hottest day recorded or length of hot days or the highest evaporation rate. Or it could be the lowest or highest rainfall recorded with associated extremes of flooding or the highest altitude with resultant snow loads. Your group is to overcome these extremities and make your building solution an ecologically sustainable solution using ideas developed from traditional methods sourced from overseas. We are primarily focusing on characteristics of the environment and climate that impinge on building design and deriving solutions that would be acceptable to our culture in Australia. You can use modern building methods or materials to construct your building designs, but the focus is traditional solutions. You can use solar panels to generate both electrical & hot water, but again the focus is traditional solutions. The keywords are ecologically sound solutions that are climatically appropriate to the area you are assigned. Common problems • You are to discover countries that have similar climatic zones, and determine from your research the type of traditional building, that might have appropriate lessons for your allocated area. You must NOT include a general discussion of the cultural, geographic or political background of the country, unless it relates to the design of buildings. Marks will be deducted for padding. • Structural concerns, from snow, floods, earthquake & hurricanes should only be discussed if they affect the lighting, acoustic or thermal characteristics of the building. • You must include a Table of Contents, Conclusion and Reference list (Harvard method); overall it must be a professional report. See the Learning Guide for more details. Assessment (20% of final mark for the unit) Demonstrate how the environmental factors influence the design of traditional buildings in your similar region and how these principles can be applied and implemented to buildings at your location in Australia. This will be done through: 1. A 25 minute maximum verbal presentation (say 15 minute talk {i.e. app. 3 minutes each} and 5 minutes questions to the whole group). The presentation must be accompanied by PowerPoint slides (or similar). 2. A written submission; The length of the report is not critical but there should be input from all members of the group and heat, light and sound should be covered.. Diagrams and photographs are encouraged and should be referenced separately. This is a guide only. You may write a longer or shorter report if you want to do so. It is the quality of what is written that counts. 3.
