C、        A higher level of network security can be reached by separating sensitive data traffic from other network traffic．
D、        Port-based vlans increase switch-port use efficient,thanks to 802．1Q trunks
E、        A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure．
答案C,E
解析 A错，不是通过物理上组合，而是逻辑上的，
B错，应该是增加广播域的数量，
C一个更高的层次网络安全可以实现,以分离的敏感数据从其他网络。正确，
D thanks to 802．1Q trunks不正确，
