Exercise 1

Question 1 :

What type of local file server can you use to provide the distribution installation materials to the new machine during a network installation?


A). Inetd
B). FSSTND
C). DNS
D). NNTP
E). NFS
Answer : Option E

Explanation :

You can use an NFS server to provide the distribution installation materials to the machine on which you are performing the installation. Answers a, b, c, and d are all valid items but none of them are file servers. Inetd is the superdaemon which controls all intermittently used network services. The FSSTND is the Linux File System Standard. DNS provides domain name resolution, and NNTP is the transfer protocol for usenet news.


Question 2 :

If you type the command cat dog & > cat what would you see on your display? Choose one:


A). Any error messages only.
B). The contents of the file dog.
C). The contents of the file dog and any error messages.
D). Nothing as all output is saved to the file cat.
Answer : Option D

Explanation :

When you use & > for redirection, it redirects both the standard output and standard error. The output would be saved to the file cat.


Question 3 :

You are covering for another system administrator and one of the users asks you to restore a file for him. You locate the correct tarfile by checking the backup log but do not know how the directory structure was stored. What command can you use to determine this? Choose one:


A). tar fx tarfile dirname
B). tar tvf tarfile filename
