一
You are the Linux administrator of your company. You are administering the company's Linux systems. You need to configure modem support on your 486 PC.
What modem speed setting may be too high of your computer doesn't have a 16550 UART chip?
A)   28800
B)   115200
C)   56700
D)   16890  
E)   38400
参考答案：Ｂ
我的答案：Ｂ
因为看到题目里说"may be too high",所以我按着感觉选了Ｂ。但不知道为什么？


二
On Linux, what program provides menu-driven module configuration?

A)   modconf
B)   confmod
C)   modef  
D)   modcon
参考答案：Ａ
我的答案：Ａ
我根本不知道何谓menu-driven，请教？？

三
When do you need to run the lilo command?
  
a After every boot
b After every modification of the lilo configuration file
c After installing a new kernel with a new name in /boot
d After overwriting the old kernel in /boot with a new one
e  Only the first time after installing LILO
参考答案：未知
我的答案：b c d
不知道e应该不应该选上，照理安装过lilo后应该run lilo command,但选项e中有一个单词“only”所以，我又觉得不对了。


四
You have run out of disk space on a partition.Which of the following would be an easy way to move data to a new partition without reconfiguring path to the data in existing applications?
参考答案: use a symbolic link
这题题目的意思我都没有读懂，题目有岐议。磁盘空间不够的时候，任何文件都不能够建立，包括soft link。

五
Which of the following would do the same as the command cat < file1.txt > file2.txt?
参考答案：cat file1.txt > file2.txt
我的答案：cat file1.txt > file2.txt　和　cp file1.txt file2.txt
因为这里使用cat命令的作用跟使用cp命令一样嘛！


六
What TWO permissions must a user have in order to run a shell script?
a read
b execute
c browse on the directory
参考答案：a b
我的答案：a b c
经过实验，仅对目录有x权限及对文件有x权限，还不足以执行该script。还必须对文件有r权限位。


以上问题，请达人帮我看看！
