Spanning-Tree was originally developed by DEC.What is the reason Spanning-Tree is used in a switched LAN?<br>A.To Provide a mechanism for network monitoring in switched environments.<br>B.To prevent routing loops in networks with redundant paths.<br>C.To prevent routing switching loops in networks with redundant switched paths.<br>D.To manage,the addition,deletion,and naming of VLANs across multiple switched.<br>E.To segment a network into multiple collision domains.<br>我是选C的～老大解释一下吧～<br><br>［此帖子已被 飞猴 在 2003-10-26 5:58:17 编辑过］
