11. A company is installing IP phones. The phones and office computers connect to the same device. To
ensure maximum throughput for the phone data, the company needs to make sure that the phone traffic ison a different network from that of the office computer data traffic. What is the best network device to
which to directly connect the phones and computers, and what technology should be implemented on this
device? (Choose two.)

A. hub
B. router
C. switch
D. STP
E. subinterfaces
F. VLAN

答案是CF， 我的问题是，这个题从哪里看出来phones和computers要放在一个网络中？？如果没有放在一个网络的要求，为什么不能选router呢？ 哪位大侠解答一下，感激不尽啊。谢谢

the company needs to make sure that the phone traffic is on a different network from that of the office computer data traffic
电话流量和计算机流量不在一个网络内，这样的话首先应该想到用VLAN，并使用交换机来实施

用路由器扩展性不好，如果有很多台ip phone，你的路由器有那么多接口吗？
