Chapter 6: Network Design Flashcards
(20 cards)
The campus backbone (or core layer) is the network architecture component responsible for providing end user access to the network. (TRUE/FALSE)?
False
Today, many organisations design networks using the building-block approach. (TRUE/FALSE)?
True
Nowadays, most organisations use a simpler approach to a network design called the blank approach
Building-block
Which of the following is not a current trend that is making the traditional design approach less appropriate for today’s networks?
a. The underlying technology of networking devices is changing very rapidly
b. The underlying technology of client and server devices is changing very rapidly
c. The underlying technology of circuits is changing very rapidly
d. Growth in network traffic is very high
e. The most expensive part of any network is the hardware
e. The most expensive part of any network is the hardware
In needs analysis:
a. the costs of different physical network design alternatives are assessed
b. the goal is to understand what users and applications the network will support
c. the geographical scope is no an important consideration
d. a baseline of current operations is not important
e. the rate of growth of network traffic is not an issue
b. The goal is to understand what users and applications the network will support
In the blank step of the building-block process to network design, the network designer attempts to understand the fundamental current and future network needs of the various users, departments, and applications
Needs analysis
In the blank step of the building-block process to network design, the network designer examines the available technologies and assesses which options will meet the user’s needs
Technology design
In the blank step of the building-block process to network design, the network designer considers the relative costs of the technologies
Cost assessment
Which network architecture component is responsible for distributing network traffice to and from the LANs?
a. Local Area Network (LAN)
b. Building Backbone Network
c. Campus Backbone
d. Data Center
b. Building Backbone Network
What is the fourth network architecture component that contains the organisation’s servers and is essentially a LAN designed and managed differently
a. Wide Are Network (WAN)
b. Internet Access component
c. E-commerce Edge
d. Data Center
d. Data Center
What is the primary goal of the “building-block process” for network design?
a. To maximize the capacity of each network component
b. To achieve simplicity of design by using few standard components repeatedly
c. To minimise the cost of network hardware
d. To ensure every computer is assigned to the same network
b. To achieve simplicity of design by using few standard components repeatedly
What are the three main steps in the building-block network design process?
a. Planning, Implementation, Maintenance
b. Needs analysis, Technology design, Cost assessment
c. Discovery, Prototyping, Deploymeny
d. Security assessment, Performance tuning, User training
b. Needs analysis, Technology design, Cost assessment
What is the goal of the “needs analysis” step in the network design?
a. To assess the costs of various physical network design alternatives
b. To understand the fundamental current and future network needs of the various users and applications
c. To develop a physical network design
d. To implement network security protocols
b. To understand the fundamental current and future network needs of the various users and applications
What is “baselining” in the context of application systems in network design?
a. The process of estimating the total amount of traffice on each part of the network
b. Reviewing the list of applications that will use the network and identifying their location
c. Categorising the network needs into mandatory, desirable, and wish-list requirements
d. Developing a precise estimate of the amount of data each user will send and receive
b. Reviewing the list of applications that will use the network and identifying their location
The key deliverable for the needs assessment stage is a set of:
a. Physical network designs
b. Cost assessment reports
c. Request for Proposals (RFPs)
d. Logical network diagrams
