现在是欲哭无泪,太受打击了,<br>我决定开始发奋了.半个月之后,又是一条好汉!<br>

还有实际场景题,那是真正考分析能力的,就是我平时很你们说的troubleshooting。你还没有学会如何看问题。<br>看这题:<br><br>25.        SPOTO1#show interface <br>serial 0/0 is down, line protocol is down<br>Hardware is HD64570<br>Internet address is 172.22.5.1/30<br>MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/255, load 1/255<br>Encapsulation HDLC, loopback not set, keepalive set (10 sec)<br>Last input never, output 00:03:11, output hang never<br>Last clearing of &quot;show interface&quot; counters never<br>Input queue: 0/75/0 (size/max(drops): Total output drops: 0<br>Queuing strategy: weighted fair<br>Output queue: 0/1000/64/0 (size/max active/threshold/drops)<br>Conversations 0/2/256 (active/max active/max total)<br>Reserved Conversations 0/0 (allocated/max allocated)<br>5 minute input rate 0 bits/sec, 0 packets/sec<br>5 minute output rate 0 bits/sec, 0 packets/sec<br>0 packets input, 0 bytes, 0 no buffer<br>Received 0 broadcasts, 0 runts, 0 giants, 0 throttles<br>0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort<br>11 packets output, 476 bytes, 0 underruns<br>0 output errors, 0 collisions, 27 interface resets<br>0 output buffer failures, 0 output buffers swapped out<br>11 carrier transitions<br>DCD=down DSR=down DTR=down RTS=down CTS=down<br>SPOTO1 cannot establish a connection to SPOTO2 using the show interface serial 0/0 command on SPOTO1 command which layer of the OSI model is most likely the problem?<br>A.

Transport layer.<br><FONT COLOR="FF0000">serial 0/0 is down, line protocol is down</FONT><br>看这里,明显是广域网串口出问题了嘛,当然是物理端口问题。<br><br>这种题目最考能力的。<br>

有关局域网,DNS,VLAN,CSMA/CD的几乎都阵亡了。局域网薄弱。可以和MCSE班的同学切磋一下。<br>

这句看到了,可是选错了,概念问题

sky 发表于 2003-7-11 00:49:36

我也觉的局域网很有问题----实际上什么都很弱

还有这题(这种题目很简单,肯定要确保100%对)<br>33.        What is the broadcast address for this network 192.57.78.0/27?<br>A. 192.57.78.33<br>B. 192.57.78.64<br>C. 192.57.78.87<br>D. 192.57.78.97<br>E. 192.57.78.159<br>F. 192.57.78.254<br><br>问广播地址,必然是32-27=5位,2*2*2*2*2=32,网络地址是32*N,广播地址当然是32*N-1,所以。。。很容易筛选啊。

sky 发表于 2003-7-11 00:51:49

啊?唯一觉得比较清楚的还挂了,完了,书要从头看起了

sky 发表于 2003-7-11 00:56:40

33 E<br>是不是?

sky 发表于 2003-7-11 01:00:01

我以为广域网串口出问题,是传输的问题,没想到是物理层

chinamoon 发表于 2003-7-11 01:00:12

不过没事啦。你第一次和X3差不多,——他也被我狂打击了一下。:)<br>不过,第二次他的正确率就达到80%了,我出的题目到80%基本上是可以过的,因为相当于考试的90%了。因为我专门都是挑有特点的题目给你们模拟,简单的题目就不出了。所以,甭灰心,我对你还是很期望的。你很有可能会是这里培养的第一位女性CCIE哦,同时会是最young的。:)<br><br><br>我的建议:<br>1,重点复习局域网技术,有关Switch,VLAN等<br>2. 重点复习广域网技术,尤其是帧中继。<br>3. 读Sybex CCNA Guide,思科Student guide。<br>4. 潜下心来学习,别太心急。<br>5. 准备好后,再来找我一次,有问题这里提。
