2 Section II Question 21 (a) Identifies the purpose of a file extension and provides an example 2 Identifies the purpose of a file extension OR 1 Provides an example A file extension identifies the application required to open the particular file, eg.doc. Question 21 (b) Outlines TWO accessibility features of an operating system 2 Outlines ONE accessibility feature of an operating system OR Names TWO accessibility features Text to speech narration allows people with visual impairments to access written text by having it read out loud. Sticky keys makes it possible to use keyboard shortcuts without needing to press more than one key at once. Magnifier Voice control. 1 2

3 Question 21 (c) Explains the effect that the convergence of technologies has had on the ICT industry 4 Provides relevant examples Outlines the effect that the convergence of technologies has had on the ICT industry 3 Provides at least one relevant example Identifies some features of the convergence of technologies OR 2 Outlines ONE features of the convergence of technologies Shows a basic understanding of convergence 1 The incorporation of multiple functions within a single device has led to major changes in the ICT industry. Devices are now more complex and greater training is required for staff providing service and support for these devices. It has also led to a growth in the demand for software applications that run on mobile platforms. For example the smartphone usually includes a camera, a GPS, web browsing, ecommerce payment facilities, music, video and game player as well as a telephone. Other examples include multi-function printers that also scan, fax and copy. Question 22 Provides a description of the role of SafeWork NSW 2 Identifies a function of SafeWork NSW 1 SafeWork NSW is responsible for providing advice to organisations on improving work health and safety, investigating workplace incidents and enforcing WHS laws in NSW. Its main purpose is to help organisations to meet their WHS obligations. Licensing and registration for dangerous work. 3

4 Question 23 (a) Explains how a business may be affected by malicious software 2 Provides some relevant information 1 Malicious software such as viruses can cause corruption of files, leading to employee downtime or inability to work effectively while repairs are made. Data loss Security breaches Slow loading times / processing speeds. Question 23 (b) Provides a list of relevant troubleshooting steps 3 Identifies some relevant troubleshooting steps 2 Identifies a relevant troubleshooting step 1 Check: there is power to the device the keyboard is plugged in username and password are correct Caps Lock key not on Wi-Fi on / network connectivity cable in server is running networking equipment proxy settings if applicable. 4

5 Question 24 (a) Outlines TWO relevant factors 2 Outlines ONE relevant factor OR identifies relevant factors 1 To ensure adequate signal strength, the distance between the router and the furthest user should be less than 30 metres and the path between users and the router should have minimum obstacles, eg walls. Number of users Physical placement eg ceiling Power over ethernet Proximity to power / data points. Question 24 (b) Identifies circumstances when satellite is the most effective option for a SOHO to access the internet Identifies a circumstance when satellite is effective for a SOHO to access the internet 2 1 Office may be in a remote or rural area where other services may not be available, eg NBN, fibre, ADSL. Office may be in an area where the cost of such other services is prohibitive. 5

6 Question 24 (c) Explains how the long-term reliability of networked desktop computers 4 can be improved Outlines how the long-term reliability of networked desktop computers 3 can be improved Outlines a way of improving the long-term reliability of desktop computers OR 2 Identifies ways of improving the long-term reliability of desktop computers Identifies a way of improving the long-term reliability of desktop 1 computers Regular updates of operating system software to overcome security vulnerabilities and be compatible with relevant hardware and software. Use preventative maintenance tools such as defrag, disk cleanup and check disk to maintain efficiency of the hard drive. Ensure antivirus updates and scans are regularly performed to identify and remove potential threats. Ensure hardware components are kept appropriately clean and free of dust and dirt to prevent physical damage. Question 25 Explains the role of port assignment when configuring a firewall 3 Shows some understanding of port assignment and/or firewalls 2 Provides some relevant information 1 Individual software applications require specific ports to be available in order to operate, eg Port 80 is used by HTTP. Ports that are not required are normally closed to reduce the risk of unauthorised access or virus activity. 6

7 Question 26 Clearly shows how Bluetooth and Wi-Fi technologies are different 4 Identifies features of Bluetooth and Wi-Fi technologies showing some 3 understanding of their differences Identifies features of Bluetooth and/or Wi-Fi technologies 2 Identifies a feature of Bluetooth or Wi-Fi 1 Bluetooth is normally one-to-one connection and Wi-Fi is capable of a one-to-many connection. Bluetooth has a simple authentication with low security whereas Wi-Fi has more security options. Wi-Fi allows for file sharing between devices on the same network. Bluetooth (V4) is capable of long-range connections and higher data rates. Older versions (BR/EDR V2) of Bluetooth had a shorter range than Wi-Fi and were often used for streaming audio. Bluetooth (BR/EDR V2) uses a lower bandwidth that makes data transfer slower than Wi-Fi. 7

8 Section III Question 27 (a) Explains the benefits of entering into a vendor contract for the company 3 Shows some understanding of vendor contracts 2 Provides some relevant information 1 A benefit of a vendor contract is guaranteed support from the specific supplier within an agreed timeframe. Usually a specific technician is assigned to your business for continuity and familiarity. Also training is provided to users to allow them to quickly troubleshoot common problems. Preferential pricing (discounts) Replacement of faulty parts/equipment Software/product customisation. Question 27 (b) Explains how to efficiently achieve the required file sharing 4 Outlines how to achieve the required file sharing 3 Shows some understanding of file sharing 2 Provides some relevant information 1 Appropriate groups need to be created, for example staff and managers. A shared folder needs to be created on a network drive. The file needs to be saved in this shared folder and staff group members are allocated read only permission while members of the managers group have full permissions that allow them read/write/delete access. 8

9 Question 27 (c) Outlines ways to reduce problems with the printer showing thorough understanding of the issues indicated by the log 8 Justifies all the ways Outlines ways to reduce problems with the printer showing sound understanding of the issues indicated by the log 6 7 Justifies some of the ways Identifies ways to reduce problems with the printer in the scenario 4 5 Provides some justification for at least one of the ways Shows some understanding of how to reduce printer problems 2 3 Provides some relevant information 1 Page count (approximately 5000 per week) is too high for a small laser printer. This results in frequent toner cartridge changes. Moving to a higher capacity printer would enable longer periods between cartridge changes and lower maintenance costs. Toner cartridges are needed frequently yet each time they are required, a member of the service staff is required to order a single replacement. This means that the printer is unavailable for up to three days. Estimating the usage and ensuring there is always an adequate stock of cartridges on hand would reduce the downtime. A networked printer would be able to alert support staff when consumables such as toner and drums would need to be replaced. This would enable service staff to be proactive and undertake the replacements prior to the toner becoming exhausted. There appears to be no regular preventative maintenance taking place on this printer. If this was implemented issues such as drum replacement and cleaning could be undertaken before they cause the printer to fail. 9
