@
d
@
The correct answer is: D. suggest to the operating system that the process
may be run at a weaker priority.
Unlike other operating systems HPUX/UNIX does not allow a normal user to
directly set a process' priority (unless special real-time priority calls
are enabled and allowed). The nice command allows a user to suggest to the
kernel that a particular process may be "nice" to competing processes and
be run at a weaker priority (the root user may negatively "nice" a process
and ask the kernel to give it a stronger priority). The kernel takes this
as a suggestion and sets a process' priority according to various
utilization factors and other mysterious influences.

The correct answer is: B. bdf
The df (disk free) command appeared in early UNIX to provide this
information. The Berkeley version of UNIX enhanced the df command such that
it’s output does not match that of the AT&T definition. HPUX is fully
compliant with the System-V Interface Definition and as such maintains the
older format of output for the df command. In order to provide HPUX
administrators with the convenience of the Berkeley version output we have
implemented it as bdf (berkley disk free).

B. create a new logical volume, use the newfs command with the -F vxfs option,
mount the file system using the -F vxfs option, add an entry into /etc/fstab
C. create a new logical volume, use the fsadm command with the -F vxfs option,
mount the file system using the -F vxfs option, add an entry into

D. create a new logical volume with the -F vxfs option, mount the file system

the procedure of setup a journal file system is: first create a lv with

A. all the metadata updates are recorded in an intent log transaction record
which is physically written to the intent log on the disk.
B. some metadata changes are written to disk immediately and others will

C. all the metadata and data updates are recorded in a single intent log
transaction record which is then flushed out to disk into the intent log.
D. all the metadata changes are written only when a sync is issued.

The correct answer is: A. all the metadata updates are recorded in an intent
log transaction record which is physically written to the intent log on

When a JFS file system is mounted with the log option, all transactions
which will modify metadata are logged to the physical file system before
control is passed back to the requesting process/thread (a physical write
to the intent log must be made before the process/thread may continue).

nodes on the network?
A. /usr/sbin/ntpd.conf
B. /usr/sbin/ntpsync
C. /usr/sbin/ntpdate

server(s) on the host(s) given as arguments to determine the correct time.
It must be run as root on the local host. Typically, ntpdate can be inserted
in the startup script to set the time of day at boot time and/or can be
run from time-to-time via cron.

The nice command allows a user to:
A. send "friendly" E-mail messages to a group of users.
B. asks the system to be "nice" to the user s processes and give them
preference.
C. broadcast a greeting to all users as they logon.
D. suggest to the operating system that the process may be run at a weaker
priority.
@
d
@
The correct answer is: D. suggest to the operating system that the process
may be run at a weaker priority.
Unlike other operating systems HPUX/UNIX does not allow a normal user to
directly set a process priority (unless special real-time priority calls
are enabled and allowed). The nice command allows a user to suggest to the
kernel that a particular process may be "nice" to competing processes and
be run at a weaker priority (the root user may negatively "nice" a process
and ask the kernel to give it a stronger priority). The kernel takes this
as a suggestion and sets a process priority according to various
utilization factors and other mysterious influences.

In what situation would you normally see the error "Stale file handle" on
a :
A NFS client when a file the client has been accessing has had its mount
point removed by the NFS server

C NFS client when an attempt is made to remount an already mounted mount
point

clients are accessing.

See "man exportfs"
If an NFS-mounted directory is unexported by exportfs, any access by the
client to the directory causes an NFS stale file handle error. However,
if exportfs is used to remove a client from the access list of an exported
directory, an NFS stale file handle error does not result from any access
by the client to the directory.
