Refer to the output of the two show commands in the exhibit． If an administrator tries to ping host 10．1．8．5 from host 10．1．6．100, how will the ICMP packets be processed by Router A?

A、 The packets will be discarded．
B、 The packets will be routed out the S0/0 interface．
C、 The packets will be routed out the S0/1 interface．
D、 The packets will be routed out the Fa0/0 interface．

【正确答案】 C

【答案解析】可以看到10．1．8．5的网段不在路由表中，但是在Router A的路由表中有一条RIP的缺省路由，因此可以收到的ICMP的报文是从s0/1来的。
