Introduction:
LAN referred to as Local Area Network. It is an average geographical Network that offers
their facility in the university, college, small company, office, or firm. Documents and
resources are shared on the network for the Network communication. FootFall Field
Marketing Corporation desires a network to be able to provide a connectivity between their
group of workers and workplace. Here, I could scheme the LAN network for the given
company. There are 4 parts in the report.
The first part of report will give an explanation for LAN community with the wireless and
wired network. Then, the VLAN, intensive services of traffic, device of LAN community and
cable could be defined that beneficial for the Given LAN Network. Given LAN Network will
be deliberate in line with business enterprise needs and might be envisioned of the device
in the second part. LAN Network can be implemented and configured in the third parts. There
can be a conversation about the network protection after which trying out of the
connection of network is performed. Troubleshooting and Monitoring procedure might be
well-defined and could be solved reliability, safety, and performance problems in the fourth
parts.

LO1 - Understand the impact of LAN technologies
1.1 Critically evaluate different LAN technologies
Extends the computer network is a small geographical area, Knows as the local area
network. It connected the workplace computer, network device, and workstations to share
the device and data in the network.

Table 1: the difference between wired and wireless Network
Wireless LAN network Wired LAN Network
It gives high –security because singles
intercept is not allowed.
There is allowed the singles intercept
which gives low-level security in the
network
It gives high-speed data transmission It gives less speed
It plays and plugs the network It covers the limit area in the network.
It cheap network. It is a costly network

VLANs
VLAN referred as Virtual Local Area Network which is permitted the user split-up in the distinct
network sections because of the security reason.it supports network configuration and connectivity
of remote device of the network.
Advantage:
 It is configuring and implementation price low due to network Flexibility
 It able to manage and control the network traffic.
 It gives the network security because it supports ACLs, Authentication, and Authentication
during the network access.
 It created the segmentation of network according to user requirements.

VLAN Network Types
Data Network: it is managed the user created traffic in the network. It splits voice traffic and
data traffic. It mainly focused on the data traffic.
Default Network: After the bootup process, Switch ports are worked as default VLAN that
provisions the domain of broadcast. It provides the device connection.
Management Network: it is managed by the network capabilities on the switch. It used SSH,
Telnet, SNMP, or HTTP for management. The out-of-box configuration is supported by
Management VLAN.
Native Network: it used 802.1Q trunk ports. It managed the network untagged traffic. For
the untagged traffic, Native VLAN uses an identifier. The identifier is able to manage
inheritance LAN situations.
Voice Network: it managed the voice transmission quality on the switch, Cisco IP phone,
and PC. There are needs following requirements such as
 Latency is fewer than 15-mile sec in the LAN network.
 It accomplishes the network bandwidth for the quality
 Voice data is a priority of the network during the transmission
