Question No: 1
Given that permfile has its permissions set as follows:
Chmod 2666 permfile
Which three statements about the permfile permissions are true? (Choose three)
A. The sticky bit is set.
B. The file has the SUID bit set.
C. Mandatory locking is enabled.
D. The file is not executable by any user.
E. The associated group has read and write permissions.
F. The associated group has read, write, and execute permissions.
Answer: C,D, E.
Explanation: chmod 20#0 - if the # is 7,5,3, or 1 then Set group id on execution. If the #
is 6,4,2 then Mandatory locking is set. And 0666 means rw- for owner, group and
others. (Sticky bit is set by 1000. Set userid on execution is 4000)*
Question No: 2

Which command displays an Access Control List for a file?
A. 1sac1
B. getac1
C. aclget
D. faclget
E. getfacl
Answer: E - getfacl. setfacl is to set ACL list. Other commands do not exist.
Explanation: The following example sets the file owner permissions to
read/write/execute, file group permissions to read only, other permissions to none, and the ACL mask permissions to read on the ch2.doc file. In
addition, the user george is given read/write permissions; however, due to the ACL mask, the effective permissions for george are read only.
$ setfacl -s u::7,g::4,o:0,m:4,u:george:7 ch2.doc
$ getfacl ch2.doc
# file: ch2.doc
# owner: nathan
# group: sysadmin
user::rwx
user:george:rwx #effective:r--
group::r-- #effective:r--
mask:r--
other:---

Given:
$ 1s -1d telephone
drwxrwsrwx 2 lesley sp 512 Aug 3 17:28 telephone

B. chmod g-s telephone
C. chmod 767 telephone
D. chmod 0777 telephone

Question No: 5
Your umask value is set to 022 and you create a file. Which set of permissions are
associated with this file?
A. rw-r--r--
B. rwxr--r--
C. ----w--w-
D. rw-rw-rw-
E. rwxrwxrwx
Answer: A.
Explanation: Remember that the permissions for created files will always be the numeric
value 666 minus the umask value. (666 - 022 = 644)
Important Points: to make permanent change, change the umask value in user’s
.profile or .cshrc. If you just change it on the current shell session, the effect is only
temporary! (Next time, you log in, it will be lost!)

directory of dir1 or dir1/dir2 do not exist.
D. It creates three directories, named dir1, dir2 and dir3, and overrides the permission
modifications created by the file mode creation mask.
Answer: A.
The -p option tells mkdir to create an entire new structure at once (even the
dir1 is not exist yet) Watch out the wording - it tried to trick you!

What is the result of mounting a file system with the noatime option enabled?
A. It enables ufs logging.
B. It disables the update of file access times.
C. It prevents the creation of files larger then 2 GB.
D. It prevents the user form updating the file modification times.
Answer: B.
Reference to Solaris System Administration Guide, Vol. 1, page 444.
Explanation: Suppresses access time updates on files, except when they coincide with
updates to the ctime or mtime. See stat(2). This option reduces disk activity on file systems
where access times are unimportant (for example, a Usenet news spool). The default is normal
access time (atime) recording. This only applies to UFS.
Question No: 21
What is the name of the directory where the kernel device information file
path_to_inst is found?
Answer: /etc
More info.: The devfsadm command manages the special device files in the /dev and
/devices directories. By default, devfsadm attempts to load every driver in the system and
attach to all possible device instances. Then it creates the device files in the /devices
directory and the logical links in the /dev directory. In addition to managing the /dev and
/devices directories, devfsadm also maintains the path_to_inst(4) instance database.
Important: how to display device configuration: 3 commands - prtconf, sysdef, dmesg.

Which Run Level results in an orderly shutdown and power off, of a system?
Answer: 5. Run level 5 is “power down” init state. It will shutdown the system in an
orderly way and on system so equipped, power will be automatically removed.
Question No: 56
You are using a system running at Run Level 3. All other users have logged out. The
system runs a database application whose orderly shutdown is affected through Run
Control scripts.
Which two commands are acceptable to run before you shut the system down and turn
the system off? (Choose two)
A. halt
B. init 0
C. reboot
D. poweroff
E. shutdown -g0 -i -y
Answer: D and E.
Explanation: The halt command is an emergency shutdown command, similar to init 0.
halt should be used with care because it does not initiate the orderly shutdown of services or
clean dismounting of file system. Therefore, they (halt and init 0) are not correct choices!
Reboot is essentially the same as the init 6 command. So the system is shut down and reboot
to the system default level defined in /etc/inittab.
Poweroff command is functionally equivalent to the halt command, except that power is
removed from the system after it is halted.
Shutdown command is the recommend way to shut down the system. It first sends out
warning messages to all log-in users; this is particularly useful with multi-user servers; and it
will stop all services in an orderly way and unmount all file systems; then do a sync.
Question No: 57
In which file is the default Run Level defined?
Answer: /etc/inittab. Reference to Solaris System Administration, Vol 1.
Explanation: When you boot the system or change run levels with the init or shutdown
command, the init daemon starts processes by reading information from the /etc/inittab
file. This file defines three important items for the init process:
• The system's default run level
• What processes to start, monitor, and restart if they terminate
• What actions to be taken when the system enters a new run level
Each entry in the /etc/inittab file has the following fields:
id:rstate:action:process
