You are a network administrator for a company that is planning to open a small branch office in Idaho. The company has engaged a consultant to design the local area network (LAN) for the new office, and your supervisor has asked you to review the design submitted by the consultant. The documentation for the new network calls for the installation of 20 Ethernet workstations, all of which will be connected to a single Ethernet LAN. The consultant states in the document that “a broadband network is necessary, to enable all of the workstations to coexist on the same packet switching network,” and then calls for the installation of coaxial cable, “a broadband medium that is more than capable of supporting the communications of 20 workstations, as demonstrated in any home with cable television.” After reading the document, you immediately call your supervisor and recommend that the company find a new consultant. Which of the following are valid reasons for this conclusion?
- A.
  
  Ethernet does not run on coaxial cable.
- B.
  
  A broadband medium is not necessary to support multiple workstations on a packet switching network.
- C.
  
  Cable television networks do not use broadband signaling.
- D.
  
  Coaxial cable does not support broadband signaling.
