Assessment tasks
To achieve competency in this unit you need to successfully complete all assessment tasks:
Task1:Written Questions
Task 2:Enterprise WLAN Project
Submission detail
All tasks are to be submitted electronically via Canvas, with any required evidence attached.
Performance Objective
For this task, you will demonstrate knowledge required to design an enterprise wireless local area network.
Assessment task description
For this task, you will answer a series of knowledge questions required to design an enterprise wireless local area network.
Assessment task introduction
The project includes two main sections: Procedure and Specifications. You are required to understand the difference between these sections:
Procedure - this section describes all the requirements that are needed to be submitted step by step. You DO NOT need to answer in this part.
Specifications - this section specifies what the student MUST include as part of the project. You are required to insert an object (a document) under each of the requirements. To be deemed ‘Satisfactory’ for this project, all the requirements under the Specifications need to be submitted and completed in accordance with Skills Australia Institute’s ‘Student Handbook’ (under ‘Training and Assessment’ section).

Procedure
You are required to answer all the questions correctly to be deemed ‘Satisfactory’ for this part of the project. Write your own words for every question.
Specifications

• You must submit the answers to the following questions:
• Q1: Wireless Networks offer users the ability to access internet and data services from various devices including laptops, tablets and phones. Wireless networks present higher levels of vulnerability and as such regular network audits and surveys are necessary to test the wireless network security and gather information to redesign more secure networks. Based on this information, Identify and describe;
• One( 1) Network audit system used in wireless network surveys
• Two(2) Intrusion detection systems used in conducting network surveys
• a) Panitrating testing-
• While there are numerous sub-categories and variations, generally, the different types of penetration test can be divided into four main groups. Let’s take a look:
• 1. External network penetration test
• 2. Internal network penetration test
• 3. Web application penetration test
• 4. Social Engineering
• b) {Intrusion detention system}
• Host base / network base
• Signature base
• Anamoly base
• Anti virus for laptop
• Firewall for network {{Packet sniffer / RF sniffers}}
• Anomaly base intrusion detector machine learning / AI
• Q2: Identify and describe two (2) auditing techniques and two (2) penetration testing techniques (Pen-Tests) that are used when conducting network surveys for wireless networks.
• Pen test
• White box- aware of network
• Gray box - mix of two partial knowledge
• Black box - no previous watch
• Auditing tech
• Inventory auditing -- monitor entire assets hardware software'
• Compliance auditing - dealing with sls/ standards of industries
• Q3: Explain why a site survey is essential for ensuring that there is adequate bandwidth.
• 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.7 Sept 2017

• Q6: Outline three (3) considerations to make when selecting the type of antenna to use when designing a wireless network, based on the antennas operational features.
• Isotropic
• Directional
• Omni directional antenas
• Types of anteans and where they used mimo dual band
• Q7: A colleague has been reading on the OSI model and has asked you to explain how you what you consider when designing a wireless network. Explain three(3) considerations you make when choosing whether your wireless network design operates at layer 2 or layer 3.
• Application
• Presentation
• Session
• Transport
• Network layer 2 routers
• Datalink layer 2 switches
• Physical
• Routers are intelligent devices to improve isolation
• Dis adv- costly
• Adv - isolation , faster network compatibility
• Q8 ARPANSA and ACMA are the main organisations in Australia that regulate the licensing and use of the electromagnetic spectrum frequencies such as radio frequency (RF). They also regulate the type of equipment that can be used in RF networks. Explain three(3) ways in which the radio frequency (RF) spectrum impacts the design of wireless networks.
• Consider equipements and frequencies.
• Q9: Point to point (P2P) microwave links are used to create wireless access or backbone networks that make use of frequencies in the 300GHz-300MHz spectrum.
• Explain two (2) problems associated with designing P2P microwave links given the physical terrain (Topography) limitations of the earth surface such as the surface being uneven and curved.
• Describe how obstacles such as tall buildings in the transmission path can cause problems for the wireless links.
• a) b) Q10:Outline two (2) types of wireless topologies.
