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-

Run level 3 is to enable network services running, which is the default run level.
Question No: 55
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

标题: 献给即将或打算考SCSA的朋友们(一)
Highlight of important Concepts:
1. The Solaris 8 Operating Environment implements four disk-based file systems:
UFS - The UNIX file system (default), based on the traditional BSD file system
HSFS - The High Sierra and ISO 9660 file system (read-only) used with CD-ROMs
PCFS - The PC file system, which allows read and write access to DOS-formatted disks
UDF - Universal Disk Format file system, an optical media standard for DVD, CD-ROM, disks,
and diskettes (new in Solaris

SWAPFS, though it utilizes disk, is considered a virtual file system type.
2. 'mountall -l' will mount all local file systems. mountall refers to the /etc/vfstab file systems
and mounts all file systems with the automnt(mount at boot) field set to "yes".
'umountall -l' unmounts all local file systems.
3. When the system boots, the 'fsck' (file system check and repair program) checks file
systems using the "preen" mode (option '-o p'). The preen mode automatically corrects minor
file system inconsistencies that are known to be safely repaired without system administrator
intervention, such as:
- unreferenced inodes
- incorrect counts in superblocks
- missing blocks in the free list
Preen mode allows file systems to be checked in parallel and non-interactively, exiting if fsck
encounters problems requiring intervention.
4. The 'tunefs' command can be used to tune file system parameters for an existing UFS file
system.
Usage: tunefs [ options ] file_system
Common options:
-m minfree (Specify minimum free space, the percentage of space that is held back from
normal users when the file system is near full.)
-d rotational_delay (Specify the rotational delay, the expected time in milliseconds that it takes
the CPU between completing one data transfer and starting the next on the same disk. Used to
optimize disk transfer rates by deciding how much rotational spacing to place between
successive file blocks.)
5.
/etc/vfstab is the virtual file system table. It provides default entries for mounting file system at boot
time.
There are seven fields in an /etc/vfstab record:
- Device to mount (block special file)
- Device to fsck (raw device)
- Mount point
- FS type
- fsckpass (a number used by fsck to determine whether to check the file system automatically)
- Mount at boot (tells whether the file system should automatically mounted by mountall)
- Mount options
The record fields are separated by white-space. Hyphen indicates null.
6.
The 'umount' command unmounts file systems and removes corresponding entries from /etc/mnttab.
Usage: umount [ options ] file_system
file_system can be specified as a block special device, a mount point, or a remote resource.
Examples:
umount /export/home
umount /dev/dsk/c0t3d0s7
7. The Volume Management daemon, 'vold', performs volume management for removable
media such as CD-ROM and diskette. vold checks devices and automatically mounts media so
they are accessible.
If the media contain file systems, they will be mounted as follows:
Diskette: /floppy/floppy0
CD-ROM: /cdrom/cdrom0
Note that floppy0 and cdrom0 may change with device instances.
If the media do not contain file systems, they will be made accessible under the /vol directory
(default) as follows:
Diskette: /vol/dev/aliases/floppy0
CD-ROM: /vol/dev/aliases/cdrom0
At startup, vold reads the /etc/vold.conf file, which contains information such as which devices
to use, and actions to take in response to "insert", "eject", and "notify" events. vold also uses
the 'rmmount' command, which uses the /etc/rmmount.conf configuration file.
8.
The 'volcheck' causes the Volume Management daemon to check the specified device and mount
removable media such as CD-ROM or diskette, without the user having to log in as root.
Usage: volcheck [ options ] device_path
-v (verbose) is a commonly used option.
device_path defaults to the floppy drive at /dev/diskette.
Example: volcheck /dev/diskette
9. The steps in using Volume Management for removable media such as CD-ROM, DVD-ROM,
and diskette:
1. Insert media.
2. Execute the volcheck command, specifying the device to check
3. Work with media (located at/cdrom/cdrom0 or /floppy/floppy0 if mountable, and at
/vol/dev/aliases/cdrom0 or /vol/dev/aliases/floppy0 if not).
4. Execute the eject command on the device.
5. Physically eject the media if the eject command does not accomplish this.
Note the importance of using the 'eject' command before physically ejecting media, especially when
the device contains a mounted file system.
10. Each UFS file system has a lost+found directory, which is used when the fsck (file system check
and repair) program encounters inodes that are allocated but unreferenced (no directory links to the
inode). Responding "yes" to the fsck "RECONNECT?" question will cause such an inode to be linked
to the lost+found directory, using the inode number to name the file.
Later, the system administrator can attempt to track down the original location of files in lost+found
and copy it back. Since the file's name original name was lost, this may not be a simple task (though
directories may be easier). The file type, size, ownership, and (if text) content may provide clues.
11. The 'newfs' command is recommended to create a new UFS file system. newfs is a front
end for the 'mkfs' command, which has more complex syntax.
Usage: newfs [ options ] [ mkfs-options ] raw_device
Options:
-v (verbose)
-N (show file system parameters that would be used, without actually creating the file system)
The following defaults can be adjusted with mkfs-options:
- Logical block size 8 KB
- Fragment size 1 KB
- 1 inode per 2KB data
- Minimum percent freespace = 64 MB/partition size x 100 (next lower integer, limited to
between 1and 10%)
Example: newfs -v /dev/rdsk/c0t3d0s7
12. The / (root) and /usr file systems are considered the Solaris Operating Environment file
systems. / and /usr usually remain mounted at all times.
The root file system is the root of the entire file system. It contains system files such as the
kernel, local configuration files (under /etc), and mount points for other file systems.
/usr normally exists as a separate file system. /usr contains sharable files such as system
library routines (/usr/lib), which may be either architecture-dependent or -independent.
13. Mounting a UFS file system with the 'noatime' option will cause the file system to
skip atime (access time) updates on files, except when they coincide with mtime
(modification time) or ctime (inode change time) updates. This improves disk performance on
file systems on file systems where atime is not important.
The dfratime|nodfratime options defer writing atime updates until the disk is accessed for
another reason. Note that noatime overrides dfratime or nodfratime.
Usage: mount -o [ options ] raw_device mount_point
Example: mount -o noatime /dev/rdsk/c1t3d0s5 /export/usenet
14. You will pass the exam with high score!

多谢了啊！
呵呵，楼上的给的题目跟答案都在一起，将其拷贝到一个.txt文件中，
在unix下通过：
awk '$1!~/Answer/ {print $0}' mytest.txt >; myquestion.txt

这样就可以得到myquestion.txt的所有题目了啊！
