QUESTION 1:

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.

QUESTION 2:

Certkiller 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. Certkiller has
been growing at about twenty percent per year and it has been difficult to maintain customer support at
a satisfactory level. The Certkiller board has met and directed the CTO to look into network improvements.
Which two items are most relevant in documenting Certkiller ’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.

QUESTION 3:

640-861

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.

QUESTION 4:

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.

QUESTION 5:

640-861

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.

QUESTION 6:

Certkiller wants to improve the security of their network.
Which information supplied by Certkiller would be most relevant to the new design?

A. The network topology.
B. The speed of the network. C. The company’s user policy.
D. The number of network users.
E. The applications permitted on the network. Answer: C
Explanation:
Since the security policy of the Certkiller network is the chief concern, the current user policy would be most beneficial for the new design.
Incorrect Answers:
A: The network topology is not the primary issue.
B: Speed affect the number of users and applications and is an important consideration, but in this case we are more concerned with the security aspects.
D: Number of users matters in case of performance issue. It is not the primary issue in this case.
E: One can add or delete applications. It will not play major role

QUESTION 7:

Certkiller users have online access to sales records, customer records and billing data in various branch office databases. Certkiller want to open a new branch office in the Midwest. The new branch office will have a dispatch center which will require constant communication with the local retailers.
What additional information should you obtain about applications in use on the network?
