New features wore added to ZFS in Oracle Solaris11. Your justification to upgrade from Solaris10 to oracle Solaris11 is that it will be possible to take advantage of the enhancements that were made to ZFS.

Identify the three ZFS functions and features that are included in Oracle Solaris 11, but not in Solaris 10.

A. Encrypted ZFS datasets

B. Ability for ZFS to detect and remove redundant data from the tile system

C. Shadow Data Migration

D. Ability to split a mirrored ZFS storage pool

E. Ability to use ZFS on the boot drive and boot to a ZFS root file system.

F. elimination of the swap file system when using ZFS on the root disk

In an effort to reduce storage space on your server, you would like to eliminate duplicate copies of data in your server's ZFS file systems.

How do you specify that pool1/data should not contain duplicate data blocks (redundant data) on write operations?

A. zfs create - o compression=on pool1/data

B. zpool create -o deduplication =on pool1; zfs create pool1/data

C. zfs create - o deduplication=on pool1; zfs create pool1/data

D. zfs create - o dedupratio=2 pool1/data

E. zfs create - o dedup=on pool1/data

A non-global zone named testzone is currently running.

Which option would you choose to dynamically set the CPU shares for the zone to two shares?

A. While logged in to the global zone, enter: prctl -n zone.cpu-shares -v 2 -r -i zone testzone

B. While logged in to the global zone, enter: zonecfg -z testzone add rctl set name=zone cpu-shares setvalue=(priv=privilegedJimit=2,action=none)

C. While logged in to the global zone, enter: prctl -n 2 zone cpu-shares -i zone testzone

D. While logged in to the global zone, enter: zonecfg -z testzone add rctl set name-zone cpu-shares set value=2

E. While logged in to testzone, enter: prctl -n zone.cpu-shares -v 2 -r -i zone testzone

You created a new zpool. Now you need to migrate the existing ZFS file system from pool1/prod to pool2/ prod.

You have these requirements:

1.

Users must have access to the data during the migration, so you cannot shutdown the file system while the migration takes place.

2.

Because you want to copy the data as quickly as possible, you need to increase the server resources devoted to the ZFS migration.

Which method would you use to modify the ZFS shadow migration daemon defaults to increase the concurrency and overall speed of migration?

A. Svccfg - s filesystem/shadowd:default setprop config_params/shadow_threads=integer: 16 end svcadm refresh filesystem/shadowd: default

B. Specify the -b option with the zfs create command and increase the value of

C. Use the -o -volblocksize=option with the zfs create command and increase the value of the default .

D. Svccfg -s filesystem/zfs: default setprop config_params/shadow_threads = integer: 16 end svcadm refresh filesystem/zfs:default

You need to update an OS image on a client. The pkg publishers command displays the wrong publisher with the wrong update: PUBLISHERTYPESTATUSURI Solaris origin onlinehttp://pkg.oracle.com/solaris/release The update is available on the updated publisher:

PUBLISHERTYPESTATUSURI Solaris originonlinehttp://sysA.example.com Select the option that describes the procedure used to update the OS image on the system from the updated publisher.

A. Copy the repository from the ISO image onto the local client.

Configure the repository on the client by using the svccfg - s command so that the Solaris publisher is

connected to the new repository.

Refresh the application/pkg/server service.

Issue the pkgrepo refresh command to refresh the repository catalog

B. Configure the publisher on the client using the svcfg - s command so that the Solaris publisher is connected to the repository at http://sysA.example.com Refresh the application/pkg/server service. Issue the pkgrepo refresh command to repository catalog

C. Use the pkg set-publisher command to change the URL of the publisher Solaris to http:// sysA.example.com. Issue the pkg update command to update the OS image.

D. Add the new publisher http://sysA.example.com Solaris Use the pkg set-publisher command to set the publisher search order and place http://sysA.example.com of http://pkg.oracle.com/solaris/release Issue the pkg publisher command to view the publishers. Set the new publisher to sticky. Issue the pkg update command to update the OS image.

Before booting test zone a non-global zone, you want to connect to the zone's console so that you can watch the boot process.

Choose the command used to connect to testzone's console.

A. zoneadm -C testzone

B. zoneadm -console testzone

C. zlogin - z testzone console

D. zlogin - z testzone - C

E. zlogin -C testzone

F. zoneadm - testzone - c

Review the zonestat command:

zonestate - q physical - memory -R high -z -p -p "zones" 10 24h 60m

Select the option that correctly describes the information that is displayed by this command.

A. It is a sample of dbzone's physical memory usage taken every hour over a 24-hour period. Only the top 10 samplings of peak memory usage are displayed. All other utilization data is eliminated.

B. It is a sample of dbzone's CPU, virtual memory, and networking utilization. Physical memory is executed from the report. The sampling is taken every 10 minutes over a 24-hour period and peak utilization id displayed each hour.

C. It is a sample of dbzone's CPU, virtual memory, and networking utilization. Physical memory is executed from the report. The sampling is taken every 10 minutes over a 24-hour period and displayed each hour.

D. It is a sample of dbzone's physical memory usage taken every 10 seconds and 24-hour period. Only peak virtual memory usage and CPU utilization are displayed each hour. All other Utilization data is eliminated.

E. It is a sample of dbzone's physical memory usage taken every 10 seconds and 24-hour period. Only peak memory usage is displayed each hour. All other utilization data is eliminated.
