  5. The storage pool is 292 GB total size (rounded to the nearest GB).

Answer: A,E

Question No: 12 – (Topic 1)

Which two accurately identify features of a Solaris 10 branded zone?

  1. executes in a Solaris 10 global zone

  2. is created by importing a Solaris 10 flash archive

  3. enables Linux binary applications to run unmodified

  4. provides a complete runtime environment for Solaris 9 applications

  5. allows a Solaris 10 global zone to be migrated into a Solaris 10 non-global zone on a Solaris 11 system

Answer: B,E Explanation:

B: It can be created by importing a Solaris 10 flash archive.

You can use the Oracle Solaris Flash archiving tools to create an image of an installed system that can be migrated into a zone.

The system can be fully configured with all of the software that will be run in the zone before the image is created. This image is then used by the installer when the zone is installed.

Note: You can use alternate methods for creating the archive. The installer can accept the following archive formats:

  • cpio archives

  • gzip compressed cpio archives

  • bzip2 compressed cpio archives

  • pax archives created with the -x xustar (XUSTAR) format 脛 ufsdump level zero (full) backups

    Note:

    Branded zones that run an environment different that the OS release on the system

  • The lx branded zone introduced in the Solaris 10 8/07 release provides a Linux environment for your applications and runs on x86 and x64 machines on the Oracle Solaris

    10 OS.

  • The solaris8 and solaris9 branded zones enable you to migrate an Oracle Solaris 8 or Oracle Solaris 9 system to an Oracle Solaris 8 or Oracle Solaris 9 Container on a host running the Oracle Solaris 10 8/07 Operating System or later Oracle Solaris 10 release.

  • The Oracle Solaris 10 Container brand is available in OpenSolaris build 127. These branded zones host Oracle Solaris 10 user environments.

    Note: One of the powerful features of Solaris 11 is the ability to run a Solaris 10 environment in a zone. Solaris 10 allows you to run Solaris 8 and 9 environments in zones,but only on SPARC.

    Display information about the current configuration. If resource-type is specified,displays only information about resources of the relevant type. If any property-name value pairs are specified,displays only information about resources meeting the given criteria. In the resource scope,any arguments are ignored,and info displays information about the resource which is currently being added or modified.

    Note: zonecfg -z

    zonename. Specify the name of a zone. Zone names are case sensitive. Zone names must begin with an alphanumeric character and can contain alphanumeric characters,the underscore (_) the hyphen (-),and the dot (.). The name global and all names beginning with SUNW are reserved and cannot be used.

    When you are finished building this new server,the pool1/data dataset must be an exact duplicate of note server. What is the correct procedure to create the pool1/data dataset on this new server?

    1. zfs create -o mountpoint=/data -o refquota=1g pool1/data

    2. zfs set mountpoint=none pool1zfs create pool1/data

    3. zfs set mountpoint=none pool1zfs create -o mountpoint=/data -o quota=1g pool1/data

    4. zfs create quota=1g pool1/data

    5. zfs create mountpoint=/data pool1/data

    6. zfs set quota=1g pool1/data

    Answer: A

    Question No: 17 – (Topic 1)

    You are attempting to edit your crontab file in the bash shell. Instead of getting your usual vi interface,you are presented with an unfamiliar interface. In order to have your editor of choice-vi- what command must you type after exiting the unfamiliar editor?

    1. EDITOR=vi

    2. crontab=vi

    3. crontab – e vi

    4. env

    Answer: A Explanation:

    Set the EDITOR variable to vi.

    Commands like `crontab -e` will use ed per default. If you#39;d like to use some better editor (like vi) you can use the environment variable EDITOR:

    # EDITOR=vi; crontab -e will open the users crontab in vi. Of course you can set this variable permanently.

    Incorrect answers

    C: -e Edits a copy of the current user#39;s crontab file,or creates an empty file to edit if crontab does not exist. When editing is complete,the file is installed as the user#39;s crontab file. If a username is given,the specified user#39;s crontab file is edited,rather than the current user#39;s crontab file; this can only be done by a user with the solaris.jobs.admin authorization. The environment variable EDITOR determines which editor is invoked with the -e option. The default editor is ed(1). All crontab jobs should be submitted using crontab. Do not add jobs by just editing the crontab file,because cron is not aware of changes made this way.

    Question No: 18 – (Topic 1)

    You need to configure an ISCSI target device on your x86 based Oracle Solaris II system.

    While configuring the iSCSI device,the following error is displayed: bash: stmfadm: command not found

    Which option describes the solution to the problem?

    1. The COMSTAR feature is not supported on the x86 platform. The feature is supported only on the SPARC platform.

    2. Use the iscsitadm command on the x86 platform when configuring an iSCSI target.

    3. Install the storage-server group package on this system.

    4. Start the iSCSI target daemon on this system.

    Answer: C Explanation:

    STMF – Manages transactions,such as context and resources for Small Computer System Interface (SCSI) command execution,and tracking logical unit and port providers. STMF also handles logical unit mappings,allocating memory,recovering failed operations,enumeration,and other necessary functions of an I/O stack.

    STMF is controlled by stmfadm,and stmfadm is the majority of the commands you will be using to administer COMSTAR (COmmon Multiprotocl Scsi TARget).

    Install the packages you need for COMSTAR with iSCSI and reboot:

    # pfexec pkg install storage-server

    # pfexec pkg install SUNWiscsit

    # shutdown -y -i6 -g0

    Note: You can set up and configure a COMSTAR Internet SCSI (iSCSI) target and make it available over the network. The iSCSI features can work over a normal Internet connection (such as Ethernet) using the standard iSCSI protocol. The iSCSI protocol also provides naming and discovery services,authentication services using CHAP and RADIUS,and centralized management through iSNS.

    The COMSTAR target mode framework runs as the stmf service. By default,the service is disabled. You must enable the service to use COMSTAR functionality. You can identify the service with the svcs command. If you have not rebooted the server since installing the group/feature/storage-server package,the service might not be enabled correctly.

    Ensurepass 2018 PDF and VCE

    1. Option A

    2. Option B

    3. Option C

    4. Option D

    Answer: B Explanation:

    The zfs list command provides an extensible mechanism for viewing and querying dataset information.

    You can list basic dataset information by using the zfs list command with no options. This command displays the names of all datasets on the system and the values of their used,available,referenced,and mountpoint properties.
