Task 1: Knowledge Questions
Assessment tasks
To achieve competency in this unit you need to successfully complete all assessment tasks:
· Task 1: Knowledge Questions
· Task 2: WAN Specification Project
Submission details
All tasks are to be submitted electronically via Canvas, with any required evidence attached.
Performance Objective
You will demonstrate knowledge you applied to determine best-fit topology for a wide area network.
Assessment task description
For this task, you will answer a series of questions on the general topic of determining best-fit topology for a wide 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
1. 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: Summarise two (2) typical network topologies that are applicable for each of the following networks.
    
    1
    2
    Small LAN (less than 20 computers)
    Bus - In bus topology Local Area Networks all the nodes are connect with single the help of cable called backbone network.
    Hybrid - In hybrid network topology more than one or two differing network topologies are might be present. These topologies could be combination of bus, mesh, ring, star, tree topology.
    Large LAN (enterprise network)
    Hybrid - In hybrid network topology more than one or two differing network topologies are might be present. These topologies could be combination of bus, mesh, ring, star, tree topology.
    Bus - In bus topology Local Area Networks all the nodes are connect with single the help of cable called backbone network.
    WAN
    Full mesh – software defined WAN (SD-WAN) implementation happen in full-mesh. All sites of a user’s connected to each other through GRE and GRE_IPsec overlay tunnels. GRE_IPsec is default overlay tunnel encapsulation.
    Dual homed – Primary and secondary servers involved, when one server fails other in operations called Dual-Homing
    VPNs
    Full mesh – software defined WAN (SD-WAN) implementation happen in full-mesh. All sites of a user’s connected to each other through GRE and GRE_IPsec overlay tunnels. GRE_IPsec is default overlay tunnel encapsulation.
    Extranet topologies – For VPN network Intranet uses mostly topologies are physical and logical. In this type of call extranet topologies, implementation requirements are security of the Virtual Private Network, which could be implemented with a number of different other topologies, either with the overlay or peer-to-peer VPN model.
     VLAN (1 trunk link and 1 access link)
    Tree – Like a Brach of trees tree topology works. Nodes are connected like that. In a tree topology hierarchy created like parent and child, as connection there is only one between two nodes.
    Bus/Line Topology - In bus topology Local Area Networks all the nodes are connect with single the help of cable called backbone network.
    WLAN
    Infrastructure mode - In 802.11 Infrastructure mode device communicate with each other with Access Point (AP). In wire network infrastructure mode device communicate with physical medium and wireless devices with access points, small cells. If one Access Point (AP) connected to wired network, set of wireless stations it is referred to as a Basic Service Set (BSS).
    Independent Basic Service Set (IBSS) - IEEE standard 802.11 wireless local area networking (LAN) standards including Wireless-Fidelity, share a service set identifier (SSID) is a set of service group of wireless network devices.
    Q2: WANs require the use of both hardware (modems, routers etc) components and software components (routing protocols, switching techniques etc) to be able to transmit information over a large geographical area. Explain the concept of how modems operate including their function in a WAN.
    SOHO router, WAN contains leased circuits, MPLS as routing protocol (MPLS), Layer 2 VPNs, Layer 3 VPNs, Packet switching technique. Router comes after modem in connectivity. Internet service provider connected to modem (DSL/ISDN or analog modem). Internet send analog signal through router, switches with all ISO layers operations to Digital subscriber line Access Multiplexer (SLAM), carrier mixed with digital signal modulated and send to wall jack connected to slitter connected to MODEM. MODEM receive analog signal, MODEM converted back in digital and send to inform of Becon to access device.
    Q3:     Describe two (2) types of modems.
    1. Internal Modem/ dial-up modem – Inside the computer in the form of PCI card also called dial-up modem. v.92 protocol for communicating over copper telephone lines. It operates on telephone line. Max speed 56kbps. Cable Modem – Use co-axial cable as carrier, speed 30mpds. V.32 modem operates 9600 bits/sec
2. External Modem- Some types of external modem are USB, Cable, DSL, External wireless Modem- ADSL- if you want large capacity of down load, ADSL used. SDSL- Requirement of both Upload and download in large capacity.
    Q4:    Explain the purpose of internet protocol (IP) addressing in a WAN and identify the components of an IP addressing scheme.
    There are two type of IP address in WAN: public address and private address, router have two types of interfaces internal interfaces and external interfaces. In WAN internal interface LAN IP and external interface WAN IP, Public IPs used. Static means IP address never changes, stay with same ISP. Dynamic - IP address changes with specific time. Public – NATing used to convert public to Private. Private - If IP reach within same network called private IP. Shared IP – IPs used is shared manner. Dedicated IPs - no one else uses specific IP the range of IP address – Class’ A’ range 0 to 127 default mask of IP 255.0.0.0; Class ‘B’ range 128 to 191 mask of 255.255.0.0, class ‘C’ range 192 to 223 default mask of 255.255.255.0, Class D, Class E - 248 – 255. IPV6 – Multicast, unicast, anycast.
    Q5: The internet is the largest packet switched WAN in the world connecting many smaller LANs and metro networks. Explain how packet switching works within a WAN.
    WAN is connectivity of LAN, Routers, switches, wireless and wireline devices. In Cisco there are three modes in Packet Switching- process, Fast switching and Cisco Express Forwarding (CEF). When perform routing the packet, router remove packet’s layer two header, examines layer three addressing and decide how forward the...
