问题 Refer to the exhibit． The network administrator has verified that a functioning cable connects Switch1 and Switch2． From the output that is shown, what two pieces of information can the administrator validly conclude?
选项 A、Using a source MAC address of 0009．11f3．8848, Switch2 is sending frames to Switch1．
B、Interface fa0/1 on Switch1 is in a shutdown state．
C、The status of fa0/2 should be checked on Switch2．
D、There is likely to be an IP address issue on Switch1 fa0/1．
E、The interface is functional at OSI Layer 1．
答案C,E
解析 接口显示的notconnect， 当然需要检查对端的接口的状态了 ，一般来说交换机的接口显示为一up一 down，是物理链路出现了问题。因为他只有物理层是up的，所以我们只能说他工作在OSI的第一层。
