Question

Suppose that you are working as part of a team designing a network for XYZ high school. Consider that the school has six departments, Admin, Academic, Human Resource (HR), Finance, IT support and Sports.

1. Analyse the project hardware requirements along with the number of devices and cost. [3 Marks]

2. Justify the approach you would be taking to design the network for the school. [3 Marks]

3. Using the network simulator (such as packet tracer) design the network. [4 Marks]

4. Illustrate the network configuration you have used. [5 Marks]

Answer 1

• 1. Analyse the project hardware requirements along with the number of devices and cost

  

  2. Justify the approach you would be taking to design the network for the school.

  This system consists of a single building in which ground floor is the Admin department. The other departments include Academic and sports which are combined together as they have the same functinalities ,Human Resource (HR) and Finance.The IT support communicates with all other departments while the FTP of departments is connected tothe main router. Here various other universities are also included as data can efficiently flow.

  Several computer systems are connected to each other through network so that information can conveniently flow through the network and with access rights. Various other networking devices like switches, hubs, routers can be used for interconnection. Servers can be used so as to process data. Many schools use a separate network infrastructure for every department as a way to provide security and performance.

  3. Using the network simulator (such as packet tracer) design the network

  

  4. Illustrate the network configuration you have used.

  1.DHCP Server
  Following is DHCP Server configuration for one particular subnet created.
  Pool name: serverpool
  Default Gateway: 192.168.10.1
  DNS Server: 20.0.0.1
  Start IP address: 192.168.10.10
  Subnet Mask: 255.255.255.0
  Maximum Number of Users: 100

  2. VLAN
  VLAN 10 and VLAN 20 is created on two switches Switch1 and Switch 3(3).
  In Switch-1: Fast Ethernet 0/8 is used for VLAN 20 connection and Fast Ethernet 0/4 is used for VLAN 10 connection.
  In Switch-3(3): Fast Ethernet 0/4 and Fast Ethernet 0/5 is used for VLAN 20 connection.
  Fast Ethernet 0/6 is used for VLAN 10 connection.
  3. Subnetting
  192.168.1.1 to 192.168.1.192 is the address range available with subnet mask 255.255.255.224.
  The address range is to be divided into 4 sub-networks. As the number of subnets calculated is in powers of 2, i.e. 2 to the power of 2 = 4.
  Thus, two bits from the host portion of the IP address are taken to create following subnets:
  i. 192.168.1.0/26 to 192.168.1.63/26
  ii. 192.168.1.64/26 to 192.168.1.127/26
  iii. 192.168.1.128/26 to 192.168.1.191/26
  iv. 192.168.1.192/26 to 192.168.1.255/26
  4. Routing Protocol
  Following is RIP configuration for certain router used:
  Network Address:
  192.168.1.34
  192.168.1.35
  192.168.1.97
  192.168.1.99
  192.168.1.0
  Network address 192.168.1.34 ,192.168.1.35 ,192.168.1.97,192.168.1.99 is used for Fast Ethernet connections to subnets.
  Network address 192.168.1.0 is used for Serial connection to another router.
  5. SNMP
  Network Management is performed by using Simple Network Management Protocol (SNMP).
  All routers are provided with passwords, ‘public’ for Read Community(ro) and ‘private’ for Write Community(rw).
  MIB Browser Advanced inputs:
  Address: 192.168.10.41
  Port: 161
