1.2.1 Latency

1.2.2 Jitter

1.2.3 Loss

1.3 LAN concerns

1.3.1 Security

1.3.2 Scalability

1.3.3 Availability

Task 2

2.1 Network infrastructure Design

2.1.1 Router

2.1.2 Switches at Distribution layer

2.1.3 Switches at Access layer

2.1.4 Cables

2.2 Network components evaluation

2.2.1 Security

2.2.2 VPN

2.2.3 Scalability

2.2.4 Availability

Task 3

Task 3.1 LAN Diagram for Scenario:

Draw a complete LAN design including servers, connecting devices, workstations, peripherals, etc. for the above scenario. Please include the configuration scripts in the appendix.

3.1.1 Router Configuration :-We have configure router interface

3.2 Prepare a list of IP addresses, subnet IDs, Broadcast IDs for each department, Justify your choice for chosen techniques (VLSM or others)

3.2 IP Address and VLSM

3.3 Security technology

3.3.1 1. VLAN: A VLAN is a logical grouping of network user and resources connected to administratively defined ports on a switch. This technology is usefully for security purpose. In this scenario we have required separate VLAN for finance department so no another department person access the data.

3.3.2 ACCESS-LIST : Cisco provides basic traffic filtering capabilities with access control lists (also referred to as access lists). Access lists can be configured for all routed network protocols (IP, AppleTalk, and so on) to filter the packets of those protocols as the packets pass through a router.

3.3.3 PORT SECURITY

3.4 Test cases

Task 4

4.1 Performance baseline

4.2 Tools available to monitor the Network performance

4.2.1 How does the LAN monitor works:

4.3 Step by step process to connect new computer to the network

Task - 5 Lab work

Use a network simulator to simulate the designed LAN including the following.

Build and configuration of the devices and services within the LAN.

Implementation of specialized configuration and security mechanism within the LAN.
