A client organization is investigating deploying IP communications. It has a traditional hub- andspoke Frame Relay WAN. It has five remote sites, and the WAN link speed for each location is
512 kbps. The WAN supports typical IP-based applications, but the client will also be rolling out a
new ERP application that will be considered mission critical. Which three QoS mechanisms will be
useful in redesigning the WAN to support the mission-critical application and IP communications?

You have received an RFP from a potential client to design a network for a new corporate
campus. This campus will encompass administration, sales, and R&D, and it will pull all the

distributed IT functions into a new data center. The campus will consist of five buildings, each with
four floors. The buildings will be linked via high-strand-count, single-mode fiber-optic cable to the
new data center in building 3. Each building will have an MDF with at least one telco closet per
floor and at least two runs of Category 5 UTP cable will go to each work location. Multistrand
multimode will connect each telco closet to the MDF. Each MDF will have dedicated power circuits
and be backed up by batteries in the basement of each building and a generator.
The corporation will require 3500 TDM telephones and approximately 100 of these will be in a call
center in building 2. The corporation needs to increase collaboration in the workforce.
Employees need the flexibility to be able to move from one floor to another or from one building to
another to accomplish their jobs. Managers also need this flexibility without losing connectivity to
the corporate network or their phones. Building 4 will house R&D. This portion of the network
requires connectivity to the Internet, but it also must restrict which employees have access to
certain parts of the R&D network. The data center will house all connections to the Internet and to
the PSTN. The corporation also provides access to customers for customized applications
support. A network operations center will monitor and maintain the network on a 365/24/7 basis.
