• Question 52:

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

  

  You department's backup policy is to perform a full backup to a 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 each weekday for backing up the /data file system to a remote disk named /remote/backup?

  A. Remove the previous daily snapshot. zfs snapshot pool1.data@daily zfs send - i pool1/data@sat pool1/data@daily > /remote/backup/full
  B. Remove the previous daily snapshot. zfs snapshot pool1.data@daily zfs send - i pool1/data#sat pool1/data@daily | zfs recv remote /backup/ `date `+%m%d%'
  C. Remove the previous daily snapshot. zfs snapshot pool1.data@daily zfs send - i pool1/data@sat pool1/data@daily > /remote/backup/daily
  D. Remove the previous daily snapshot. zfs create - i pool1/data@sat pool1/data@daily zfs send pool1/data@daily | zfs remote/backup
  B. Remove the previous daily snapshot. zfs snapshot pool1.data@daily zfs send - i pool1/data#sat pool1/data@daily | zfs recv remote /backup/ `date `+%m%d%'
  C. Remove the previous daily snapshot. zfs snapshot pool1.data@daily zfs send - i pool1/data@sat pool1/data@daily > /remote/backup/daily

  ---

  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 snap2. 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. Reference: Oracle Solaris ZFS Administration Guide, Sending and Receiving ZFS Data

• Question 53:

  Solaris 11 includes a redesigned software packaging model: the Image Packaging system.

• Question 55:

  Which modification needs to be made to the Service Management Facility before you publish a new package to the IPS repository?

  A. The pkg.depotd must be disabled.
  B. The pkg/readonly property for the application/pkg/server service must be set to false
  C. The pkg/writable_root property for the application/pkg/server service must be set to true.
  D. The pkg/image_root property for the application/pkg/server service must be set to the location of the repository.
  D. The pkg/image_root property for the application/pkg/server service must be set to the location of the repository.

  ---

  pkg/image_root

  (astring) The path to the image whose file information will be used as a cache for file data.

  Reference: man pkg.depotd

• Question 56:

  Which command should you choose to display the current parameters for the FSS scheduler?

  A. dispadmin - c FSS
  B. prionctl -c FSS
  C. dispadmin -c FSS -g
  D. priocntl -c FSS -g
  C. dispadmin -c FSS -g

  ---

  The dispadmin command displays or changes process scheduler parameters while the system is running.

  -c class

  Specifies the class whose parameters are to be displayed or changed. Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter-active class, FSS for the fair-share class, and FX for the fixed-priority class.

  The time-sharing and inter- active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.

  -g

  Gets the parameters for the specified class and writes them to the standard output.

  Reference: man dispadmin

• Question 57:

  ServerA contains two ISO images of a package repository, named sol.repo.iso-a and sol.repo.iso-b respectively. You need to create a single local package repository on serverA that clients can connect to. The package repository will be stored in the /export/IPS file system and named repo. The prefered publisher will be named solans and the publisher URL will be http://serverA.example.com.

  Which is correct procedure to perform on ServerA to create the local package repository?

  A. cat sol repo iso-a sol repo iso-b > sol fill iso Mount the ISO image and use the rsync command to extract the contents of the ISO file to the /export/IPS file system. Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true Set the preferred publisher by using pkg set-publisher -G http://pkg oracle com/solaris/release/ -g http://serverA.example.com/ solans
  B. cat sol.repo.iso-a sol.repo.iso-b > /export/IPS/repo Set the pkg/inst_root property to true and the pkg/readonly property to /export/IPS Set the preferred publisher by using pkg set-publisher -G htto //serverA.example com/ \ -g http:// pkg.oracle.com/solaris/release/ solari s
  C. cat sol.repo.iso-a sol.repo.iso-b > sol.full.iso Mount the ISO image and use the rsync command to extract the contents of the ISO file to /export/IPS/repo Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true Set the preferred publisher by using pkg set-publisher Solaris \ -g hflpy/serverA.example.cQm/
  D. cat sol repo.iso-a sol repo iso-b > /export/IPS/repo.iso Mount the ISO image and copy the repo directory from the ISO image to /export/IPS/repo Set the pkg/inst_root property and the pkg/readonly property to /export/IPS/repo Set the preferred publisher by using pkg set-publisher -G http://serverA.example com/ \ -g http://pkg.oracle.com/solaris/release/ -p solans
  A. cat sol repo iso-a sol repo iso-b > sol fill iso Mount the ISO image and use the rsync command to extract the contents of the ISO file to the /export/IPS file system. Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true Set the preferred publisher by using pkg set-publisher -G http://pkg oracle com/solaris/release/ -g http://serverA.example.com/ solans

• Question 58:

  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
  D. Signed cryptographic plugins (providers)
  E. Kernel support for signed antivirus plugins

  ---

  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.

• Question 59:

  You create a flash archive of the Solaris 10 global zone on the serves named sysA. The archive name is s10-system.flar, and it is stored on a remote server named backup_server.

  On sysA, you create a Solaris 10 branded zone named s10-zone.

  You want to use the flash archive, located On" /net/bactup_servers/10-system.flar, to install the Operating system in the s10-zone zone.

  Which command do you choose to install the s10-system.flar archive in the Solaris 10 branded zone (s10-zone)?

  A. zoneadm -z s10 -zone install - a /net/backup_server/s10-system.flar -u
  B. zonecfg -z s10 -zone install - a /net/backup_server/s10-system.flar -u
  C. zoneadm - z s10 -zone clone - s /net/backup_server/s10-system.flar
  D. zone cfg - a s10-zone create - t SUNWsolaris10\
  E. zonecfg -z s10-zone install -f /net/backup/backup_server/s10-system.flar
  A. zoneadm -z s10 -zone install - a /net/backup_server/s10-system.flar -u

  ---

  The zoneadm command is the primary tool used to install and administer non-global zones. Operations using the zoneadm command must be run from the global zone on the target system.

  How to Install the solaris10 Branded Zone A configured solaris10 branded zone is installed by using the zoneadm command with the install subcommand. Example: global# zoneadm -z s10-zone install -a /net/machine_name/s10-system.flar
