Question

Explain the methodologies and design issues that will need to be addressed by the network architect when planning and designing a network. Also, detail how hardware, software, data, and media will determine the technology implemented. Include discussion on how devices such as switches, routers, and IOS function within a network.

Answer 1

solution:

Implemneting network for an infrastructure is the primary requirement of an organization such that each and every devices present within the infrastructure can connect with each other. Methodologies such as what type of topologies will be best for business and how to implement such topologies to function properly. Even choosing the correct network device is also very important for a business perspective. All these factors are important and all these factors can cause issues as well such as:

• Compatibility issue: may be few devices will not be compatible with the existing software version you are using. Hence you will be unable to connect to the other devices in the network.
• Security: It is also important to implement proper security in your infrastructure such that your data is safe from threats. Security realated issues will be quite common.
• Devices issue: May be for your infrastructure you don't require specific devices as they are meant to be used for larger infrastructure.

Coming to the hardware part if the infrastructure, you need to make sure that you are using proper network devices such as routers and switches so that it can be easily connected to different network both inside and outside of the infrastructure.

Software or proper application must be installed such that they can be easily hosted on your network and you need to make sure that your firewalls are properly enabled such that outside untrusted traffic don't get into the network.

Proper network level data encryption should be done such that your data is not vulnerable to attacks or someone can't able to decrypt and exploit the data easily.

1. Swiches are used to connect the devices within a network. Let say an example, all the machines in your accounts depart ment are connected to a switch. Similarly, finance department, IT department are using individual switches to connect.
2. Routers are used to connect other networks such that through the help of routers we can communicate between department networks as well as to the internet. Routers will route the packets to other networks thereby establishing a connection.
3. The IOS is used to enable communication of data between network nodes. It can even be used to improve the performance of the network traffic and enhance security.
