What is the next step in the design methodology a network designer would take

after identifying customer requirements?

A. Design the topology.

B. Design network solutions.

C. Characterize the existing network.

D. Build a pilot network.

E. Plan the implementation.

Answer: C

Explanation:

Before beginning the design phase of a new network, the network designer must first

identify the customer needs and requirements so that a full understanding of what the

network is used for is accomplished. The next step is to characterize the existing network,

and then finally once that step is done the network designer should extract the new

customer requirements so that they can be compared to the existing network.

certkingdom is planning to upgrade its current network. The chief technology officer

(CTO) has supplied a topology diagram and IP addressing scheme of the current

network during an interview. certkingdom has been growing at about twenty percent

per year and it has been difficult to maintain customer support at a satisfactory

level. The certkingdom board has met and directed the CTO to look into network

improvements.

Which two items are most relevant in documenting certkingdom ‘s business

requirements?

A. Improved customer support

B. Existing network topologies

C. IP addresses assigned by the ISP

D. Projected growth

E. Frequency of board meetings

Answer: A, D

Explanation:

Based on the facts provided about this network, it is clear that the chief concerns that

need to be addressed is the rate of growth of the company and the network, and the level

of customer support. When any growing company expands quickly, it is common for the

company to outgrow the capacity of the network, requiring additional network equipment

and resources.

Proof of concept is required for a proposed design of a new campus network that

utilized multilayer switching. The production network is business critical and no

network disruptions are tolerated.

Which approach should be used to verify this design?

A. Pilot network

B. Prototype network

C. Hardware simulation

D. Expert consensus

E. None of the above

Answer: B

Explanation:

A prototype is a complex and full trial run of the network design used to prove that the

design works. A prototype is usually a large-scale, fully functional form of a new design

and thus is used to prove a large implementation. The customer would have to decide

whether the need to prove the design justifies the cost of setting up a prototype. If the

prototype is not appropriate for your customer, you might consider recommending a

pilot, which is a smaller test designed for smaller businesses. The pilot usually tests more

basic functions of the design, and it also usually requires less time and fewer resources.

The criteria for choosing either test plan involves comparing the cost of the test against

the need to prove that the design works. In this case, the network elements being tested

are critical, so a full blown prototype should be used to test the design fully.

Which factor is a social requirement that will help you to identify current and

future needs of your customer as you develop a new design plan?

A. Improved communications

B. Business partnerships

C. Improved customer-support services

D. The use of the network by its users as it relates to investors

Answer: C

Explanation:

Social requirements define the use of the network based on the company’s business goals

by its users and can include locations, market position, investors, vendors and customers.

Developing the customer relations aspects such as identifying their future needs fall into

this category.

Which organizational constraint most directly affects the social requirements of a

business?

A. Budget

B. Personnel

C. Policy

D. Schedule

Answer: B

Explanation:

Social requirements define the use of the network based on the company’s business goals

by its users and can include locations, market position, employees, unions, investors,

vendors and customers. Employee relations and changes in personnel fall under the

category of business social requirements.
