• Question 211:

  ServerA contains two ISO images of a package repository named so1.repo.iso-a and so1.repo.iso-b respectively. You need to create a single local package repository on server that clients can connect to. The package repository will be stored on the /export/IPS file system and named repo. The preferred publisher will be named solaris and the publisher URL will be http://serverA.example.com.

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

  A. cat so1.repo.iso-a sol.repo.iso-b > so1.full.isoMount 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 -Ghttp://pkg.oracle.com/solaris/release/ \-g http"//serverA.example.com/ solaris

  C: To disconnect from a non-global zone, use one of the following methods.

  *

  To exit the zone non-virtual console: zonename# exit

  *

  To disconnect from a zone virtual console, use the tilde (~) character and a period: zonename# ~.

• Question 213:

  Which two SMF milestones can be specified at boot time?

  A. none

  B. network

  C. all

  D. config

  E. unconfig

  F. devices

  Correct Answer: AC

• Question 214:

  A user on the system has started a process, but it needs to be terminated.

  The process ID was determined as follows:

  pgrep userprogram

  l5317

  The user attempted to terminate the program as follows:

  pkill 15317

  This command runs without an error message, and the process continues to run.

  What is the issue?

  A. You need to run the pkill command with the process name.

  B. You need to switch to super user to kill the process.

  C. You need to run the ps command to get more information.

  D. You need to run the prstat command to get more information.

  Correct Answer: B

  You can use the pgrep and pkill commands to identify and stop command processes that you no longer want to run. These commands are useful when you mistakenly start a process that takes a long time to run.

  To terminate a process:

  Type pgrep to find out the PID(s) for the process(es).

  Type pkill followed by the PID(s).

  You can kill any process that you own. Superuser can kill any process in the system except for those processes with process IDs of 0, 1, 2, 3, and 4. Killing these processes most likely will crash the system.

• Question 215:

  User jack on host solaris attempts to use ssh to log in to host oracle and receives this message:

  jack@solaris:~$ ssh oracle

  ssh: connect to host oracle port 22: connection refused

  What is the problem?

  A. Host oracle does not have a valid host public key.

  B. Host oracle does not have a valid host private key.

  C. Host solaris does not have a valid host public key.

  D. Host does not have a valid host private key.

  E. Host solaris is not configured for host-based authentication.

  F. Host oracle is not configured for host-based authentication.

  G. Host oracle is not running the ssh service.

  H. Host solaris is not running the ssh service.

  Correct Answer: G

  The host he is trying to connect to (oracle) is not running the required service (ssh).

• Question 216:

  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.comRefresh 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 SolarisUse the pkg set-publisher command to set the publisher search order and place http://sysA.example.com of http://pkg.oracle.com/solaris/releaseIssue the pkg publisher command to view the publishers. Set the new publisher to sticky. Issue the pkg update command to update the OS image.

  Correct Answer: C

  You can use the pkg set-publisher command to change a publisher URI.

  Changing a Publisher Origin URI

  To change the origin URI for a publisher, add the new URI and remove the old URI. Use the -g option to add a new origin URI. Use the -G option to remove the old origin URI.

  # pkg set-publisher -g http://pkg.example.com/support \ -G http://pkg.example.com/release example.com

  Note: You can use either the install or update subcommand to update a package. The install subcommand installs the package if the package is not already installed in the image. If you want to be sure to update only packages that are already installed, and not install any new packages, then use the update subcommand.

• Question 217:

  You need to connect two nonglobal zones using a private virtual network.

  Identify the network resources required in the global zone to accomplish this.

  A. an etherstub and two virtual network interfaces

  B. a virtual bridge

  C. two virtual network interfaces.

  D. two etherstubs

  Correct Answer: A

• Question 218:

  You have Solaris 11 system with a host name of sysA and it uses LDAP as a naming service.

  You have created a flash archive of sysA and you want to migrate this system to an Oracle Solaris11 server, Solaris10 branded zone.

  The zone Status on the Oracle Solaris 11 server is:

  -zone10 incomplete/zone/zone1solaris10exc1

  Select the option that will force the non-global zone to prompt you for a host name and name service the first time it is booted.

  A. Use zonecfg to change the zonename before booting the system for the first time

  B. Use the - u option with the zoneadm - z zone10 attach command.

  C. Use the -u option with the zoneadn -z zone10 install command.

  D. Remove the sysidcfg file from the /root directory before booting the non- global zone.

  Correct Answer: C

  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 219:

  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?

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

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

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

  D. Start the iSCSI target daemon on this system.

  Correct Answer: C

  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.

• Question 220:

  To inspect network interface net3, you enter the following commands:

  

  What problem do you suspect? Assume the user is authorized and provided the correct password.

  A. The net3 interface hasn't been enabled yet.

  B. The net3 vnic hasn't been created.

  C. The net3/v4 ip object hasn't been configured.

  D. The net3 interface is not attached to a NIC or etherstub.

  Correct Answer: C

  The following command marks the address object net1/v4a up that was previously marked down. # ipadm up-addr net1/v4a
