Question 3

You created a script (/root/bin/backup.sh) that backs up your files when executed. Using cron, you want to execute this script once every Saturday at 3:00 pm. Which line would you have to enter after invoking crontab - e in a terminal window?
A) 15 0 * * 6 /root/bin/backup.sh

Question 5

You want to boot your system to runlevel 3. Which option do you have to enter at the GRUB boot manager dialog?
A) 3
B) init=3
C) boot=3
D) runlevel=3

Entering "3" at the GRUB boot manager dialog sets the system to boot into runlevel 3, which is a multi-user mode with networking but without a graphical interface.

Question 6

Which statement about the Set User ID bit on executable files is correct?
A) The SUID bit has no security implications.
B) The SUID bit on executables has no effect; it is only relevant when set on directories.
C) The SUID bit makes it more difficult to exploit any potential vulnerabilities in the program.
D) The SUID should only be set when really needed and only on applications that are well tested.

Accepted Answer

The SUID (Set User ID) bit allows users to execute a file with the permissions of the file owner. This can have security implications if not managed properly, so it should only be set when necessary and on well-tested applications to prevent unauthorized access or privilege escalation.

Question 7

You want to copy the mytext file from your computer to the /tmp/ directory on the remote computer da20. digitalairlines.com. Which command would you use to accomplish this?
A) ssh mytext da20.digitalairlines.com:/tmp
B) scp da20.digitalairlines.com:/tmp mytext
C) scp mytext da20.digitalairlines.com:/tmp
D) sftp mytext da20.digitalairlines.com:/tmp

Accepted Answer

The `scp` command is used to securely copy files between hosts on a network. The correct syntax is `scp source_file user@host:destination_path`. Here, `mytext` is the source file, and `da20.digitalairlines.com:/tmp` is the destination path on the remote host.

Question 8

What is the effect of selecting the option "Enable IP Forwarding" in the routing configuration in YaST?
A) IP packets that do have this host as their destination are routed to another host.
B) IP packets that do not have this host as their destination are filtered according to the firewall rules.
C) IP packets that do have this host as their destination are dropped to protect the host from attacks.
D) IP packets that do not have this host as their destination are transferred from one network connected to the host to another network connected to this host, according to the routing table.

Accepted Answer

Enabling IP Forwarding allows the host to route packets between different networks, meaning packets not destined for the host can be forwarded to other networks based on the routing table.

Question 9

What is the minimum number of partitions required by a SLES 10 system?

A) passwd -L tux
B) passwd -v tux
C) passwd -p tux

Question 20

You are viewing the manual page of crontab, but it does not contain the information you are looking for. You suspect there is another crontab manual page. Which command could you use to find out if another crontab manual page exists? (Choose 2.)
A) man a crontab
B) whatis crontab
C) man -k crontab
D) man --next crontab
E) man --showall crontab
