关于CCNA的试题:详见下↓ ^ ^(我在下面!)正确答案是:A D.我想知道C怎么错了呢?请说明下
2.Which is true regarding EIGRP successor routes?(Choose two)
A. A successor route is used by EIGRP fo forward traffic to a destination.
B. Successor routes are saved in the topology table to be used if the primary route fails
C.Successor routes are flagged as "active" in the routing table
D.A successor route may be backed up by a feasible successor route
E.Successor routes are stored in the neighbor table following the discovery process
C,标记为"active“的时候说明网络进入震荡,进行“DUAL即弥散更新算法”向邻居询问路由条目,所以这样的路由还在询问阶段,所以是不会加入到路由表中的,只有标记为“passive”的时候才会加入到路由表.
这属于NP的内容了,感觉这道题有点超.加油!
