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. Which advanced technologies will be applicable to answering this RFP? (Choose three.)
A. storage
B. IP communications
C. security
D. routing and switching
E. data center
