Question One $[30$ Marks$]$

Company Overview: Richfield Graduate Institute of Technology is experiencing rapid growth as a technology

institution focused on software development and IT services. With a workforce exceeding $200$ employees and

various departments housed within a spacious office environment, the company's operational efficiency hinges

significantly on a robust and reliable network infrastructure. This infrastructure plays a pivotal role in

seamlessly connecting teams, facilitating smooth communication, and supporting critical daily operations

across the organization.

Challenge: As Richfield Graduate Institute of Technology expanded its operations and onboarded additional

employees, they encountered numerous challenges related to their inadequate networking infrastructure.

Issues such as sluggish data transfer speeds, frequent network interruptions, and difficulties in supporting the

growing number of connected devices became prevalent. It became increasingly apparent that the current

networking cables were insufficient to cope with the escalating demands of the expanding business operations.

$1\mathrm{.}1$ Advise the institution on the standardization they should have implemented initially for them to have a

secure and reliable network through analysing how the networking cabling infrastructure will move from the

Demarc to their workstations located at the third floor? $(20$ Marks$)$

$1\mathrm{.}2$ As Richfield Graduate Institute of Technology just hired a new intern for their network technician role

who is worried about designing their LAN using a switch or a Hub since they have a tight budget and

still looking forward to scaling their network as there is promising future growth for the company,

kindly advise the differences between these networking devices and advise which device he should

recommend. $(10$ Marks$)$

Question Two $[30$ Marks$]$

$2\mathrm{.}11000$Base TX is abbreviated in a logical topology to preserve space kindly advise what it says about a

network $(5)$

$2\mathrm{.}2$ Using an example, describe how an intranet network is differentiated from an extranet network. $(10)$

$2\mathrm{.}3$ How does the relationship between throughput and bandwidth impact the performance of a network

communication system? $(5)$

$2\mathrm{.}4$ How does the CSMA$/$CD $($Carrier Sense Multiple Access with Collision Detection$)$ protocol contribute to

efficient data transmission in Ethernet networks? $(5)$

$2\mathrm{.}5$ When do Ethernet networks become insufficient in terms of speed and efficiency for data transmission

needs? $(5)$

Question Three $[30$ Marks$]$

$3\mathrm{.}1$ A device server is characterized by a minimal operating architecture that requires no percentage

network operating system license, and client access that is independent of any operating system or

proprietary protocol. Outline three types of device servers and how they facilitate remote monitoring of

industrial systems. $.(10)$

$3\mathrm{.}2.$ How does the ring topology function in computer networking, and what advantages does it offer in

terms of data transmission and network management compared to other topologies. $(10)$

$3\mathrm{.}3$ Compare the principles, advantages, and disadvantages of Asynchronous Transfer Mode $($ATM$)$ and Token

Ring networks in a concise format.
