Answer the following questions and then refer to Appendix G, "Answers to Review Questions, Case Studies, and Simulation Exercises," for the answers.
What factors must be considered when designing a campus network?
A company keeps all its servers and workstations within one building. What geographical design structure should be chosen?
What are some of the differences between inter-building and distant remote network geographical structures?
The Engineering department has requirements to use a bandwidth- and processor-intensive research application. What type of application communication should it use?
What are some of the benefits of using LAN switches over hubs?
Some users in a department use an application that generates many broadcast frames, which results in up to 10 Mbps bandwidth utilization. Which of the following solutions is the most optimal in this case?
Provide 100 Mbps or higher connections to all users in a domain
Limit the number of broadcast frames in a domain for all department users
Optimize the application
Put the application users into a separate broadcast domain
What type of cable would you recommend for connecting two switches that are 115 m apart?
What is the intended result of the application characterization process?
With default Spanning Tree Protocol parameters, how long could it take before the redundant link is available when the currently active link fails?
Compare the range and bandwidth specifications of UTP, MM fiber, and SM fiber.
What are the benefits of using Layer 3 switches over Layer 2 switches?
The users in an organization are divided along their workgroup lines into VLANs. Workgroup servers are located within these workgroup VLANs. The organization has also placed mail and web servers, to which all corporate users have access, in a separate VLAN. What is the expected traffic flow in this organization?
A company is using video on demand, which utilizes IP multicast as part of its distance-learning program. The routers are configured for IP multicast. Taking into account that the majority of the LAN switches are Layer 2 switches, which protocol should be enabled on the LAN switches to reduce flooding?
Which Enterprise Campus modules typically have both high availability and high performance requirements?
What is the difference between the 80/20 rule and the 20/80 rule?
A link between the building distribution and campus backbone is oversubscribed, yet carries mission-critical data along with Internet traffic. How would you ensure that the mission-critical applications are not adversely affected by the bandwidth limitations?
What are two uses of redundant paths?
A corporate network is spread over four floors. There is a Layer 2 switch on each floor, each with more than one VLAN. One connection from each floor leads to the basement, where all WAN connections are terminated and all servers are located. Traffic between VLANs is essential. What type of device should be used in the basement?
What applications might require the network to handle multicast traffic?
What functions does the Building Distribution submodule provide?
What is the main focus of the campus backbone?
An organization requires a highly available core network and uses IP telephony for all of its voice communication, both internal and external. Which devices and topology would you recommend for the campus backbone design?
A company has mission-critical applications hosted on common servers that are accessible to selected employees throughout the company's multiple buildings. Where and how would you recommend that these servers be placed within the network?
What is the function of the Edge Distribution module?
