Question

Quiz #2 You are only allowed one submission. If you missed the deadline, you will not receive credits. You are not allowed to communicate the question and answer to others.

Background Information:

Ava is starting a new business/company. Within this new business, 90% of the business operations are NOT mission-critical: whereas the other 10% of the business operations are mission-critical. Her new business needs an intranet that consists of two or more local area networks in order to support the business operations. Her understanding of local area network (LAN) is that there are 3 types of LANs available:

• Ethernet

• Token Ring

• FDDI

She does not have sufficient technical knowledge to select the correct local area networks needed to support her business operations. You are asked to propose local area networks needed to support her business operations. Your proposal must include:

1. The number of local area networks that you propose.

2. For every proposed local area network, you must indicate the type.

3. For every proposed local area network, you must specify the reason why this local area network in needed.

Hints:

• You are NOT asked to provide definitions.

• You are NOT asked to describe the differences among these local area networks.

• You are NOT asked to describe how these local area networks work.

Answer 1

1)The number of local area networks that I propose is 2.

Reason:It is stated in problem that 90% of buissness opration are not business critical and only 10% is mission critical.So for managing the critical oprations and maintaining the internal communication 2 Lan are enough.

2)The type of Lan that should be used is Ethernet for both Lan.

Reason: Requirement for problem are

Fast speed and security

a)why Not token ring

In token ring network when one token is passed no other node is allowed to pass token or to send data.This will reduce the Rate of data tranfer will be low.

b)why not FDD

FDD is generally uses large spectrum bandwidth for two way commincation for wide area and is also expensive. The problem statement does not require two way communication so there is no need to use .

c)why to use Ethernet

Ethernet give faster speed than token ring .It gives around 10mpbs.It is cheaper than anyother Lan.It is faster and easy to implement .So implementing Ethernet will be better choice as it will provide faster speed, secure connection and cheaper cost.
