Assessment Task 1: Written questions
Task summary
This is an open-book test, to be completed in the classroom.
A time limit of 3 hours to answer the questions is provided.
You need to answer all of the written questions correctly.
Your answers must be word processed and sent to the assessor as an email attachment.
Required
Access to textbooks and other learning materials.
Computer with Microsoft Office and internet access.
Timing
Your assessor will advise you of the due date of this assessment.
Submit
Answers to all questions.
Assessment criteria
All questions must be answered correctly in order for you to be assessed as having completed the task satisfactorily.
Resubmission opportunities
You will be provided feedback on your performance by the assessor. The feedback will indicate if you have satisfactorily addressed the requirements of each part of this task.
If any parts of the task are not satisfactorily completed, the assessor will explain why, and provide you with written feedback along with guidance on what you must undertake to demonstrate satisfactory performance. Reassessment attempt(s) will be arranged at a later time and date.
You have the right to appeal the outcome of assessment decisions if you feel you have been dealt with unfairly or have other appropriate grounds for an appeal.
You are encouraged to consult with the assessor prior to attempting this task if you do not understand any part of this task or if you have any learning issues or needs that may hinder you when attempting any part of the assessment.
Written answer question guidance
The following written questions use a range of “instructional words” such as “identify” or “explain”, which tell you how you should answer the question. Use the definitions below to assist you to provide the type of response expected.
Note that the following guidance is the minimum level of response required.
    Analyse: when a question asks you to analyse something, you should do so in detail, and identify important points and key features. Generally, you are expected to write a response one or two paragraphs long.
Compare: when a question asks you to compare something, you will need to show how two or more things are similar, ensuring that you also indicate the relevance of the consequences. Generally, you are expected to write a response one or two paragraphs long.
Contrast: when a question asks you to contrast something, you will need to show how two or more things are different, ensuring you indicate the relevance or the consequences. Generally, you are expected to write a response one or two paragraphs long.
Describe: when a question asks you to describe something, you should state the most noticeable qualities or features. Generally, you are expected to write a response two or three sentences long.
Discuss: when a question asks you to discuss something, you are required to point out important issues or features and express some form of critical judgement. Generally, you are expected to write a response one or two paragraphs long.
Evaluate: when a question asks you to evaluate something, you should put forward arguments for and against something. Generally, you are expected to write a response one or two paragraphs long.
Examine: when a question asks you to examine something, this is similar to “analyse”, where you should provide a detailed response with key points and features and provide critical analysis. Generally, you are expected to write a response one or two paragraphs long.
Explain: when a question asks you to explain something, you should make clear how or why something happened or the way it is. Generally, you are expected to write a response two or three sentences long.
Identify: when a question asks you to identify something, this means that you are asked to briefly describe the required information. Generally, you are expected to write a response two or three sentences long.
List: when a question asks you to list something, this means that you are asked to briefly state information in a list format.
Outline: when a question asks you to outline something, this means giving only the main points, Generally, you are expected to write a response a few sentences long.
Summarise: when a question asks you to summarise something, this means (like “outline”) only giving the main points. Generally, you are expected to write a response a few sentences long.
Assessment Task 1 Instructions as provided to students
Provide answers to all the questions below:
Explain the purpose of intrusion detection and prevention systems and how such systems operate.
An intrusion attack can cause serious damage to your networks and integrated systems. To mitigate risks of unauthorized access to enterprise networks, the Intrusion Detection System (IDS) is an effective security solution. It proactively analyses, detects, and alerts you to suspicious activities in your network.
Identify three factors that may affect signal quality and that could be identified through a site survey.
Factors Affecting Wireless Networking Performance
· Physical Obstructions.
· Network Range & Distance between Devices.
· Wireless Network Interference.
· Signal Sharing.
Explain why a site survey is essential for ensuring that there is adequate bandwidth and quality of service.
The result of not having accurate bandwidth is that critical business functions and communication could be interrupted due to network traffic bottlenecks. A thorough site survey can form the basis of determining the proper bandwidth needed based on number and types of users, as well as devices and locations.
Outline the two types of antenna and why each one may be used for designing a wireless network.
An Antenna is a structure affiliated with the region of transition between the guided wave and free space. A signal from a transmission line or the guiding device like a co-axial cable, is given to an antenna, which then converts the signal into electromagnetic energy to be transmitted through space.
Some of the common types of antennas are mentioned below:
· Wire Antennas
· Short Dipole Antenna
· Dipole Antenna
· Loop Antenna
· Monopole Antenna
· Log Periodic Antennas
· Bow Tie Antennas
· Log-Periodic Antennas
· Log-Periodic Dipole Array
· Aperture Antennas
· Slot Antenna
· Horn Antenna
· Microstrip Antennas
· Rectangular Microstrip Patch Antenna
· Quarter-Wave Patch Antenna
Explain two advantages and two disadvantages of both layer 2 and layer 3 networks.
· Layer 2 Data Link: Responsible for physical addressing, error correction, and preparing the information for the media
Layer 3 Network: Responsible for logical addressing and routing IP, ICMP, ARP, RIP, IGRP, and routers
· Advantages of Layer 2 include lower costs, only requires switching, no routing gear is necessary and offers very low latency. Layer 2 also has disadvantages such as the lack of router hardware, leaving them susceptible to broadcast storm.
· Layer 2 networks forward all traffic, especially ARP and DHCP broadcasts. Anything transmitted by one device is forwarded to all devices. When the network gets too large, the broadcast traffic begins to create congestion and decreases network efficiency.
· Layer 3 devices, on the other hand, restrict broadcast traffic such as ARP and DHCP broadcasts to the local network. This reduces overall traffic levels by allowing administrators to divide networks into smaller parts and restrict broadcasts to only that sub-network.
· This means there is a limit to the size of a layer 2 network. However, a properly configured layer 3 network with the correct knowledge and hardware can have infinite growth.
· A Layer 3 switch is a high-performance device for network routing. A router works with IP addresses at layer 3 of the model. Layer 3 networks are built to run on layer 2 networks.
Explain three essential considerations in relation to radio frequency and design of WLANs.
· High Density Client Coverage Requirements.
· Roaming and Voice Coverage Requirements.
· Location-Aware Coverage Requirements
Explain the impact of topography and obstacles on radio frequency signals.
· Topography and buildings affect radio signals in different ways, depending on the frequency used. Very low frequencies, let’s say up to 50KHz, can penetrate water, whereas higher frequencies cannot. That is why very low frequencies are used for communications with submarines.
· The reach of the groundwave, that follows the curvature if the earth, of a radio signal decreases with increasing frequency. The consequence of this is that here in Holland it is quite possible to receive French radio, Polish, Danish and Czech radio all day long on longwave frequencies with stable signals. These low frequencies are not...
