1.The service configuration repository provides a per-service
snapshot at the time each service is successfully started so that
fallback is possible. The SMF service always executes with the
running snapshot. This snapshot is automatically created if it does
not exist.
You find that the console-login service configuration on a
server is wrong, and now need to take steps to fix the problem by
reverting to the last snapshot that started successfully. Once you
have logged in as superuser or equivalent role you run the
following commands.
# svccfgsvc:> select system/console-login:defaultsvc:
/system/console-login:default> listsnapinitialrunningstart svc:
/system/console-login:default> revert startsvc:
/system/console-login:default> quit
You have two more steps to complete in this process, which are
necessary to update the information in the service configuration
and to restart the service instance.
What two commands would you run to update the repository with
the configuration information from the start snapshot and then
restart this service instance? Mark for Review(4) Points
(Choose all correct answers)
svcadm restart system/console-login (*)
svcadm refresh system/console-login (*)

2.You have used the prtdiag command on a server to get some
information about the system configuration, diagnostics, and failed
FRUs. When the prtdiag command was executed the following exit
value of 1 was returned.
Which option describes the meaning of this exit value?Mark for
Review(2) Points
Indicates that failures or errors were detected in the system.

3.The response time within a newly configured zone is very poor,
and many services are not running. The person that configured this
new zone booted it and logged in successfully.
Within the new zone the following command is run, which explains
the state of services.
# svcs xvNo output for more than 5 minutes.
From this generated message, you surmise what the probable cause
of the slow zone is and run the next set of commands:
# zoneadm z newzone halt# zonecfg z newzonezonecfg:newzone>
remove capped-memoryzonecfg:newzone> commitzonecfg:newzone>
infozonecfg:newzone> exit# zoneadm z newzone boot# zlogin

The zone should now run faster than before.
Which option would be the cause of this poor response time
reported on this new zone? Mark for Review(2) Points
Loopback file system not enabled.
Zone mis-configured; resources caps to low. (*)
Zone initiation failed.
Physical memory capping changed.
Correct!
4.System performance, especially for compute-bound processing is
not very good. You run the mpstat command for a short time and see
that the CPU system time (sys) is fairly high, even on a system
that is not doing much.

5.The Automatic System Recovery (ASR) feature enables the server
to automatically configure failed components out of operation until
they can be replaced. In the server, the ASR feature manages
nonfatal hardware failures associated with memory modules and PCI
cards. To display system components and their current state you run
the following command.
sc> showcomponent
Keys:/SYS/MB/PCI_MEZZ/SYS/MB/PCI_MEZZ/PCIE4/SYS/MB/PCI_MEZZ/XAUI4/SYS/MB/PCI_MEZZ/PCIE5/SYS/MB/PCI_MEZZ/XAUI5/SYS/MB/PCI_MEZZ/PCEI6/SYS/MB/PCI_MEZZ/PCIE7/SYS/MB/PCI_MEZZ/PCIE8/SYS/MB/PCI_MEZZ/PCIE9
.. /SYS/TTYADisabled Devices /SYS/MB/CMPO/L2_BANK0
Once a faulty component has been disabled and after the cause of
the fault has been repaired (for example FRU replacement, loose
connector reseated), you must remove the component from the ASR
blacklist database. What two options describe the command to remove
a disabled component and the name of the database containing the
list of all disabled components on the system? Mark for Review(3)

package in a non-global zone.
# zlogin webroot@web# pkg install apptracepkg install: Could not
complete the operation on /var/pkg/lock: read-only filesystem.
You have the user check the settings of the zone, using the
following command to look for a specific setting that may cause a
read-only file system.
# zonecfg z web infozonename: webzonepath: /zones/webbrand:
solarisautoboot: truebootargs:file-mac-profile: strict
The user locates a file-mac-profile property in the output of
the command, which has been set to a value of strict. By default, a
zonecfg file-mac-profile property is not set in a non-global zone.
The default policy for a nonglobal zone is to have a writable root
file system. Knowing this information, you tell the user that this
is the desired setting placed on the non-global zone and should not
be changed.
Which statement is true when describing the profile strict? Mark

20.The svc.configd repository daemon for SMF is invoked
automatically during system startup, and restarted if any failures
occur. When svc.configd daemon is started, it does an integrity
check of the SMF configuration repository. In this example the
integrity check failed and svc.configd wrote the following message
to the console.
svc.configd: smf(5) database integrity check of:
/etc/svc/repository.db
failed. The database might be damaged or a media error might
have prevented it from being verified. Additional information
useful to your service provider is in:
/etc/svc/volatile/db_errors
The system will not be able to boot until you have restored a
working database. svc.started (1M) will provide a sulogin(1M)
prompt for recovery purposes. The command:
/lib/svc/bin/restore_respository
can be run to restore a backup version of your repository. See
http: //sun.com/msg/SMF-8000-MY for more information.
You enter maintenance mode and run the restore_repository
command, which takes you through the necessary steps to restore a
non-corrupt backup.
