requirements
Topology: It defines the physical arrangement of the devices used for the networking. These are
mainly driven by the two types of network connection. In the point-to-point type of connections,
there is a direct link which is established between the two devices. In the connections of multipoint
type, the link is established between multiple devices.
Technology: LAN is a network of data communication that connects different terminals in a
particular area. The connections of the devices can be wired or wireless. Following are the LAN
technologies:
Ethernet
Wireless LAN
Token Ring (Stallings, 2018)

A.C 2.2 Critically evaluate the suitability of LAN components
Following are the components of the LAN:
1. Switch: This is a fundamental part of the network. They allow the nodes to communicate
with other nodes in an efficient and smooth manner. The switches in the LAN provide a
separate connection to each node in the internal network of the company. The switch then
creates a series of a network consisting of two devices.
2. Routers: Routers are the network devices that forward the packets of data among the
computer networks. The routers direct the functions on the internet. The data sent on the
internet is in the form of data packets. The routers forward these packets from routers to
other routers in the network. These routers are attached with many data lines of various
networks. The most common type of network is small office and home routers. These simply
forwards the IP packets.
3. Hubs: A hub is also called as a network hub. It acts as a common point of connection of the
devices that are used to connect with the segments of the LAN. A hub consists of many
ports. Whenever a packet comes at any of the port, it gets copied to other ports as well so as
to allow segments of LAN to see the packets. It acts as a central connection of all the
equipment of the network.
The Topologies of the LAN are
There are following types of LAN topologies:
1. Ring Topology
2. Mesh Topology
3. Hybrid Topology
4. Bus Topology
5. Star Topology
6. Cellular Topology

Ring Topology:
In this type of topology, the addresses do not match with each other so the nodes regenerate those
messages and then sends them. Then if the address gets matches, the node will accept the message
and then replies back to the real sender of the message. In the beginning, this topology was easy to
install but these require large media than other systems as the loops are needed to be closed. After
installing the ring, it gets more difficult to reconfigure them.
Advantages:
1. It is simple to troubleshoot them.
2. The workstations which get troubled gets identified easily in this topology.
Disadvantages:
1. It is difficult to reconfigure and install.
2. Any media failure can cause the whole network to fail.

Mesh Topology:
It is exactly a design having point-to-point connections. Every device in this network have links
between them. However, this is not a practical design as this causes wastage of media throughout
the transmission. This is also difficult to reconfigure and install. In this, the number of devices
connected affects the speed of the communication. The most common example of this network is
Switched hubs and ATM.
Advantages:
1. It is simple to troubleshoot
2. Faults can be easily identified.
Disadvantages:
1. As a number of connections of devices increase, it gets difficult to reconfigure and install
this.

Bus Topology:
In the bus topology, if a message gets missed or goes unrecognized, it then reaches to the end of
cable and them dissipates to the terminator. The nodes in this topology have the equal access to the
truck. No type of discrimination can be done in this topology. This is done by using drop cables of
short length. This is an easily installed design and also minimizes the transmission of the media
required.
Advantages:
1. It is easy to install and makes use of only established standards.
2. Needs lesser media
Disadvantages:
1. These are not easy to reconfigure.
2. These are not easy to troubleshoot.

Star Topology:
This type of topology is not easy to install as each device needs its own segment dedicated to itself.
So more cabling is required. This results in the easy process of troubleshooting and reconfiguration.
Changes can be easily implemented in this topology.
Advantages:
1. Very simple to reconfigure.
2. Any type of media fault gets easily identified.
3. Simple to troubleshoot.
Disadvantages:
1. They need more cables for the connection.
2. A little difficult in the process of installation because of cables (Davis, 2018).

Cellular Topology:
It is a combination of wireless multipoint design and point-to-point designs that are used to divide
an area into many cells. Every cell in the network visualizes the overall area of the network in which
that connection is operated. Al devices in a cell connection communicate with one central hub.
These hubs are connected so as to route the data of the cells.
Advantages:
1. These are simple to install
2. Troubleshooting can be easily done
3. Faults get isolated easily.
4. It does not need reconfiguration of the media.

A.C 3.2 Implements network security on a LAN
The organization wants a long-term network for the communication and sharing purpose so there is
a need for the network security. Customer or user shares their important information. VLAN
trunking, router security, and Access lists are implemented in the Network for security purpose. It
provides network security when the packet transmission from source to destination.
VLAN trunking: It is a Cisco Exclusive. It focused the VLANs configuration across the designed LAN
Network. VTP supports to maintain and propagate VLAN configurations constancy to other network
switches. It is message protocol where trunk frames may be added deleted or renamed on the single
VLANs domain. It supports a centralized change in the network. It also manages the VTP server. The
server(s) will segment VLAN info with other network switches which must be used the identical
domain name (Bull, Matthews, and Trumbull, 2016).
Figure 19: Implementation of VLAN trunking as security purpose
Access control lists: It is a collection of the rules which manage the network traffic and moderates
network attacks. It is mainly focused on traffic filtration process which is implemented on the Switch
or router configuration. It provides the firewall protection in the network. It is a combination of
traffic encrypted, VPN tunnel, and VPN.
ACLS use reason in the Network
It manages the network traffic that improved the network performance.
Manage the traffic flow in the network
It provides basic level security such as network security, server security, or service security.

Router configuration: Router is a network device that provides the connective in the network. It
gives the connection between the inner network and outside the network. It manages the packet
loss on the Network path. It only supports the authorized user in the network. LAN network needs a
router configuration proper manner otherwise creates the security issue in the network. Improper
router configuration allows all user to access the network packets during packet transmission ( Asati,

A.C 4.2 Resolves LAN issues to improve security, reliability and performance
Here, I have defined various types of methods that may help to improve the LAN issues which are
mainly related to performance, reliability, security and performance
Reliability: Network reliability depended on the router speed which is through the speed
measurement in GB or MB. There is used TCP/IP network and packet transmission to enhance the
network reliability. Orthogonal frequency division is a technique that is used to increase network
reliability.
Performance: LAN network contains simple connection which easily implemented and configured.
Access control and VLANs are increased the LAN network performance. There is also used to
protocol acceleration for network performance improvement. Packet shaping and QoS implemented
in the LAN that may be increased the LAN network performance.
Security: LAN network use password protected and Encryption technique for network security
purpose. The network needs also regular base change Wi-Fi name, IP address. It provides the
network security. Remote access obligation is deactivated to network security. For the bug or virus
detection, there is a need for regular based software updating.
Here, I have define difference between trunk port and Access port such as
Access port VLAN trunking
It handles specified transports traffic for
security purpose.
It handles all transports traffic that creates security
issues
It works on all network devices It handles a specified network device
It is capable to manage one VLAN set-up on
the interface
It is capable to manage more than one VLAN set-up
on the interface
It supports untagged mode. It supports trunk mode (Bertolaccini, Viti, and Terzi,
2015)
According to the above define difference, access lists could be better than VLAN trucking.
In the LAN Network, authentication is a procedure that confirms and ensures a Network user’s
distinctiveness. Verification is one of the 5 supports of IA (information assurance). Availability,
integrity, non-repudiation and confidentiality are other four supports of IA. With the help of
