Read the scenario below and then answer the questions that follow: Mr. Khoza runs a small business in Midrand, Gauteng. His business has been steadily growing since its inception in February 2019in spite of the ill-effects of the COVID19 lockdowns as well as the ripple effects of the Russia-Ukraine such as rising fuel prices and inflation. He, Mr. Khoza, has asked you to design a secure network for his small business. Additionally, he would like you to design and build a cost-effective network for his business. The current setup is such that every PC and laptop user uses a 3G dongle to connect to the internet. When users need to print they either copy the work that needs to be printed to USB flash drives or email their work to any one of the five users whose PCs are attached to a printer - all printers connect via USB cables. The new network, according to Mr. Khoza, should cater to at least thirty devices, fifteen desktops (PCs), seven laptops including Mr. Khoza's laptop, two servers and four BYOD devices. Additionally, Mr. Khoza wants to allow visitors such as customers and suppliers to connect mobile devices to get internet connectivity. All users with PCs and laptops should still be able to print. The premises where Mr. Khoza runs his business has six offices (rooms). All the rooms are located on the same floor. Mr. Khoza has an office and does not share office space. There are two open plan offices, the first open plan office houses seven desktops and the remainder of the PCs are housed in the second open plan office. Two laptop users share an office while the other three laptop users share a separate office. A small storeroom has been selected for use as a server room.Question 1: (Marks: 40) @ The Independent Institute of Education (Pty) Led 2022 Page D of 21 18; 19; 20, 21 2022 Q.1.1 Write a short report to present to Mr, Khoza that clearly explains how the new (10) network design will save Mr. Khoza's business money if implemented.
