Reveal answer details Close answer details

Correct answerC

Explanation

Explanation: Oracle Solaris 10 branded zones ?Oracle Solaris 10 Zones provide an Oracle Solaris 10 environment on Oracle Solaris 11. You can migrate an Oracle Solaris 10 system or zone to a solaris10 zone on an Oracle Solaris 11 system in the following ways:

* Create a zone archive and use the archive to create an s10zone on the Oracle Solaris 11 system.
This option applies in the current scenario.
Example of command to Install the Oracle Solaris 10 non-global zone. s11sysB# zoneadm -z s10zone install -u -a /pond/s10archive/s10.flar

* Detach the zone from the Oracle Solaris 10 system and attach the zone on the Oracle Solaris 11 zone.
The zone is halted and detached from its current host. The zonepath is moved to the target host, where it is attached.

Note:
install [-x nodataset] [brand-specific options]
A subcommand of the zoneadm.

Install the specified zone on the system. This subcommand automatically attempts to verify first. It refuses to install if the verify step fails.

-u uuid-match
Unique identifier for a zone, as assigned by libuuid(3LIB). If this option is present and the argument is a non-empty string, then the zone matching the UUID is selected instead of the one named by the -z option, if such a zone is present.

Question 9

Multiple choice

Identify the two security features incorporated in the Oracle Solaris 11 Cryptographic Framework.

A
Layer 5 IP address encryptions
B
Internet protocol security
C
Diffie-Kerberos coaxial key encryption
D
Signed cryptographic plugins (providers)
E
Kernel support for signed antivirus plugins

Reveal answer details Close answer details

Correct answersD, E

Explanation

Explanation: The framework enables providers of cryptographic services to have their services used by many consumers in the Oracle Solaris operating system. Another name for providers is plugins. The framework allows three types of plugins:

* User-level plugins - Shared objects that provide services by using PKCS #11 libraries, such as
pkcs11_softtoken.so.1.
* Kernel-level plugins - Kernel modules that provide implementations of cryptographic algorithms in software, such as AES.

Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware.

* Hardware plugins - Device drivers and their associated hardware accelerators. The Niagara chips, the ncp and n2cp device drivers, are one example. A hardware accelerator offloads expensive cryptographic functions from the operating system. The Sun Crypto Accelerator 6000 board is one example.

The following steps are completed on the system that is providing the storage device.
1. Create a ZFS storage pool.
Example: target# zpool create sanpool mirror c2t3d0 c2t4d0 (C)2. Create a ZFS volume to be used as a SCSI LUN. (D)3. Create a LUN for the ZFS volume.
Example:
target# stmfadm create-lu /dev/zvol/rdsk/sanpool/vol1 Logical unit created:
600144F0B5418B0000004DDAC7C10001

4. Confirm that the LUN has been created.
Example
target# stmfadm list-lu
LU Name: 600144F0B5418B0000004DDAC7C10001 (F) 5. Add the LUN view.
This command makes the LUN accessible to all systems.

target# stmfadm add-view 600144F0B5418B0000004DDAC7C10001

How to Create the iSCSI Target

This procedure assumes that you are logged in to the local system will contains the iSCSI target.
Note: The stmfadm command manages SCSI LUNs. Rather than setting a special iSCSI property on the ZFS volume, create the volume and use stmfadm to create the LUN.

(H) 1. Enable the iSCSI target service.
target# svcadm enable -r svc:/network/iscsi/target:default (I) 2. Create the iSCSI target.
target# itadm create-target

each interval report.
* duration (here 24 h)

* -R report[,report] (here high)
Print a summary report. high Print a summary report detailing the highest usage of each resource and zone during any interval of the zonestat utility invocation.

Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as a percentage of system resources and the
zone's configured limits.

The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval. The default output is a summary of cpu, physical, and virtual memory utilization. The -r option can be used to choose detailed output for specific resources.

Question 16

Multiple choice

View the Exhibit to inspect the file system configuration on your server.

Your department's backup policy is to perform a full backup to remote system disk on Saturday.

On each weekday, you are to perform an incremental backup to the same remote system disk.
Each incremental backup will contain only data that has been modified since the previous Saturday backup.

The server file systems must remain available at all times and can never be taken offline. The backup must not only provide for the recovery of the most recent version of a file, but must also allow recovery of previous versions of a file.

Following your company policy, which two describe the correct procedure to be performed on Saturday for backing tip the /data file system to a remote disk named /remote/backup?

A
On Saturday:
zfs snapshot pool1/data@sat
zfs send pool1/data@sat > /remote/backup/full
B
On Saturday:
zfs create snapshotpool1/data@sat
zfs send pool1/data@sat | zfs recv remote/backup/ `date' `+%m%d%y'
C
On Saturday:
zfs create snapshotpool1/data@sat

D
On Saturday:
zfs create snapshotpool1/data@sat
zfs send pool1/data@sat | zfsrecv remote/backup

Reveal answer details Close answer details

Correct answersB, C

Explanation

Explanation: You can use the zfs send command to send a copy of a snapshot stream and receive the snapshot stream in another pool on the same system or in another pool on a different system that is used to store backup data.

You can send incremental data by using the zfs send -i option.

For example:

host1# zfs send -i tank/dana@snap1 tank/dana@snap2 | zfs recv newtank/dana Note that the first argument (snap1) is the earlier snapshot and the second argument (snap2) is the later snapshot. In this case, the newtank/dana file system must already exist for the incremental receive to be successful.

The incremental snap1 source can be specified as the last component of the snapshot name. This shortcut means you only have to specify the name after the @ sign for snap1, which is assumed to be from the same file system as snap 2. For example:

host1# zfs send -i snap1 tank/dana@snap2 > zfs recv newtank/dana This shortcut syntax is equivalent to the incremental syntax in the preceding example.
