QUESTION 5
Consider the following commands on a newly installed system:
zfs set compression=on rpool
zfs get –H –o source compression rpool
What is the output of the second command?
A. default
B. –
C. local
D. on
Answer: C
Explanation: The zfs get command supports the -H and -o options, which are designed for
scripting. You can use the -H option to omit header information and to replace white space with
the Tab character. Uniform white space allows for easily parseable data. You can use the -o
option to customize the output in the following ways:
* The literal name can be used with a comma-separated list of properties as defined in the
Introducing ZFS Properties section.
* A comma-separated list of literal fields, name, value, property, and source, to be output followed
by a space and an argument, which is a comma-separated list of properties.
The following example shows how to retrieve a single value by using the -H and -o options of zfs
get:
# zfs get -H -o value compression tank/home
on
QUESTION 6
You want to create a ZFS file system with the following specifications:
lzjb compression enabled
Cannot consume more than 2 GB from the storage pool
Redundant data at the block level eliminated
Mounted as /data
Which command creates the desired file system?
A. zfs create –o mountpoint=/data,compression=on,algorithm=lzjb,deduplication=on,quota=2g
/pool1/data
B. zfs create –o mountpoint=/data compression=on algorithm=lzjb deduplication=on quota=2g
/pool1/data
C. zfs create –o mountpoint=/data –o compression=on –o dedup=on –o quota=2g /pool1/data
D. zfs create –o mountpoint=/data –o compression=on –o algorithm=lzjb –o deduplication=on –o
quota=2g /pool1/data
E. zfs create pool/data zfs set mountpoint=/data,quota=2g, dedup=on,compression=on /pool1/data
Answer: C
Explanation: Not on compression setting:
compression=on | off | lzjb | gzip | gzip-N
Controls the compression algorithm used for this dataset. The
“lzjb” compression algorithm is optimized for performance while
providing decent data compression. Setting compression to “on” uses
the “lzjb” compression algorithm.
Incorrect:
Not A, Not E: Should not use commas like this.
Not B, Not D: There is no property algorithm named to this command. To specify the use of the
lzjb compression command we must use compression=lzjb.
QUESTION 7
Which two zpool subcommands will permanently remove a submirror from active storage pool?
A. remove
B. detach
C. destroy
D. offline
E. replace
F. split
G. zpool does not permit this operation on an active storage pool unless the submirror faults.
Answer: A,B
Explanation:
zpool detach pool device
Detaches device from a mirror. The operation is refused if there
are no other valid replicas of the data.
QUESTION 8
Your task is to configure storage for an Oracle Solaris 11 system to support multiple web servers.
Each web server will be contained in a separate zone. The system has an attached disk array
configured as a JBOD (Just a Bunch Of Disks). The system also has an internal solid-state drive.
The data accessed through the websites will be primarily read-only. The web servers are expected
to be very busy, so configure the storage for maximum performance. Because the data is primarily
static, but redundancy is required to maintain high availability in the event of a hardware failure.
Data does not change often, but it is expected that the same data will be accessed many times
throughout the day.
Which configuration option best meets the data storage requirements?
A. a raid2 storage pool with a separate log device
B. a mirrored storage pool with a separate cache device
C. a mirrored storage pool with a separate log device
D. a three disk striped storage pool with a separate cache device
E. a raidz1 storage pool with a separate log and cache device
Answer: B
Explanation: Required to maintain high availability –> use a mirror.
The same data will be accessed many times throughout the day. Configure the storage for
maximum performance. Use caching.

# zfs send –i dpool/sales/qrreports@qtrreport dpool/sales/qrreports@mth3qtrreport
A. An error message will be sent to standard error.
B. The dpool/sales/qrreports@qtrreport snapshot is saved to disk.
C. The dpool/sales/qrreports@mth3qtrreport snapshot is saved to disk
D. The difference between the First snapshot and the second snapshot will be written to disk

QUESTION 3
To reduce the use at storage space on your server, you want 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 on write operations?
A. zfs create –o compression=on pool1/data
B. zpool create –o deduplication=on pool1 ; zfs create pool1/data
C. zpool create –o dedupratio=on pool1 ; zfs create pool1/data
D. zfs create –o dedupratio=2 pool1/data
E. zfs create –o dedup=on pool1/data
Answer: E
Explanation: To c reate a file system with deduplication:
root@solaris:~# zfs create -o dedup=on
Note: If you have a storage pool named ‘tank’ and you want to use dedup, just type this:
zfs set dedup=on tank
QUESTION 4
Which option lists default checkpoints for building an image using the Distribution Constructor?
A. manifest-valid and ba-init
B. ba-arch and grub-setup
C. transfer-ips-install and pre-pkg-img-mod
D. pkg-img mod and create-usb
Answer: C
Explanation: The following list provides a brief description of each default checkpoint in the order
the checkpoints are executed in most manifests.
transfer-ips-install – At this checkpoint, the distribution constructor contacts the IPS publishers and
adds to the image the packages that are listed in the software_data element of the manifest.
set-ips-attributes – At this checkpoint, the constructor sets the publisher to be used by the installed
system. The values set by this checkpoint are not relevant if you are building an automated
installation image.
pre-pkg-img-mod – At this checkpoint, the constructor imports into the image the SMF service files
that were specified in the configuration element of the manifest. Also, the constructor modifies
some files to optimize the image.
QUESTION 5
Which two statements describe the capabilities of the Distribution Constructor?
A. ISO images for use with the Automated Installer (AI) can be created.
B. Bootable USB images can be created for SPARC and x86 architectures.
C. A single installation server can be used to create ISO images, for SPARC and x86
architectures.
D. Checkpoints are used to pause the build, thereby allowing the running of a script to modify the
resulting ISO image.
E. A single installation server can be used to create ISO images for Solaris 10 and Solaris 11.0
operating systems.
Answer: A,D
Explanation: A: Oracle Solaris Image Types include:
x86 or SPARC ISO Image for Automated Installations – The Oracle Solaris release includes the
automated installer tool. The automated installer (AI) is used to automate the installation of the
Oracle Solaris OS on one or more SPARC and x86 systems over a network.
D:
* You can also create custom scripts to modify your installation image. Then, you can add
checkpoints to the manifest file to run these custom scripts.
* You can use the options provided in the distro_const command to stop and restart the build
process at various stages in the image-generation process, in order to check and debug the image
that is being built. This process of stopping and restarting during the build process is called
checkpointing. Checkpointing is optional. Default checkpoints are specified in each manifest file.
Incorrect:
Not B: Only for x86, not for SPARC- Oracle Solaris x86 LiveCD – You can create an x86 ISO image that is comparable to the LiveCD
image that’s distributed as an Oracle Solaris release. You can also modify the content of this ISO
image by adding or removing packages. You can revise the default settings for the resulting
booted environment to create a custom ISO image or USB image.
Note: The distribution constructor creates images based on settings specified in XML files, called
manifest files. The manifest files contain specifications for the contents and parameters for the ISO
images that you create using the distribution constructor. The distribution-constructor package
provides sample manifests that can be used to create a custom x86 Live Media ISO, an x86 or
SPARC Automated Install ISO image, or an x86 or SPARC text installation ISO image.
The elements in each manifest file provide preset, default values that will create the type of ISO
image you need. You can manually edit these preset elements in a manifest file to customize the
resulting image. In addition, you can create custom scripts to further modify your image. Then,
reference the new scripts in the manifest file.
