• Question 114:

  Consider the following rule file for use with the Basic Audit Reporting Tool (BART). CHECK all IGNORE dirmtime /etc/security /etc/notices IGNORE contents /export/home IGNORE mtime size contents /var CHECK You are using BART to detect inappropriate changes to the file system. Identify the two correct statements describing the attributes recorded.

  A. /var/dhcp Attribute: size uid gid mode acl

  B. /etc/hosts Attributes: size uid gid mode acl intime dest

  C. /var/spool/mqueue Attribute: size uid gid mode acl dirmtime

  D. /etc/security/exec_attr Attribute: size uid mode acl mtime devnode

  E. /export/home/kate/.profile Attributes: uid gid mode acl dirmtime

  F. /export/home/rick/.profile Attributes: size uid gid mode acl mtime contents

  Correct Answer: DF

  Explanation: D: According to line /etc/security

  F: According to line /export/home Not E: According to line IGNORE dirmtime Note: In default mode, the bart compare command, as shown in the following example, checks all the files installed on the system, with the exception of modified directory timestamps (dirmtime):

  CHECK all IGNORE dirmtime

  Note 2: The Basic Audit Reporting Tool (BART) feature of Oracle Solaris enables you to comprehensively validate systems by performing file-level checks of a system over time. By creating BART manifests, you can easily and reliably gather information about the components of the software stack that is installed on deployed systems.

  BART is a useful tool for integrity management on one system or on a network of systems.

• Question 115:

  Identify three options that describe the new Oracle Solaris 11 zone features.

  A. There are boot environments for zones.

  B. Administrators can delegate common administration tasks by using RBAC.

  C. Oracle Solaris 11 supports Solaris 8, 9, and 10 branded zones.

  D. You can migrate a physical Solaris 10 system and its non-global zones to a solaris10 branded zone running on an Oracle Solaris 11 system.

  E. It is possible to change the host ID of a zone.

  Correct Answer: ABD

  Explanation: A: The beadm utility includes support for creating and administering non- global zone boot environments. Note: A boot environment is a bootable instance of the Oracle Solaris operating system image plus any other application software packages installed into that image. System administrators can maintain multiple boot environments on their systems, and each boot environment can have different software versions installed.

  B: Role-based access control (RBAC) is a security feature for controlling user access to tasks that would normally be restricted to the root role. By applying security attributes to processes and to users, RBAC can divide up superuser capabilities among several administrators.

• Question 116:

  The captured packets are those__________.

  A. sent, prior to VLAN tag modifications

  B. received, after VLAN tag modifications

  C. received, prior to VLAN tag modifications

  D. sent and received, after VLAN tag modifications

• Question 117:

  You need to update an OS image on a client. The pkg publisher command displays the wrong publisher with the wrong update:

  PUBLISHERTYPESTATUSURI

  solansohQinonlinehttp://DkQ.oracle.conVsolaris/release The update is available on this updated publisher:

  PUBLISHERTYPESTATUSURI

  solarisoriQJnonlinehttp://svsA.example.com

  Select the option that describes the procedure used to update the OS image on this 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 svccfg -s command so that the solans publisher is connected to the repository at http://svsA.example.com. Refresh the application/pkg/server service. Issue the pkgrepo refresh command to refresh the repository catalog

  C. Use the pkg set-publisher command lo change the URL of the publisher solans to htto://svsA example.com. Issue the pkg update command to update the OS Image.

  D. Add the new publisher http://svsA.example.com Solaris. Use the pkg set-publisher command to set the publisher search order and place http://svsA example com ahead of http://pkg.oracle.com/solaris/release. Issue 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

• Question 118:

  You have set up the task.max-lwps resource control on your Solaris 11 system.

  Which option describes how to configure the system so that syslogd notifies you when the resources control threshold value for the task.max-lwps resource has been exceeded?

  A. Use the rctladm command to enable the global action on the task.max-lwpa resource control.

  B. Modify the /etc/syslog.conf file to activate system logging of all violations of task.max- lwps and then refresh then svc: /system/system-log:default service.

  C. Activate system logging of all violations of task.max-lwpp in the /etc/rctldm.conf file and then execute the rctladm-u command.

  D. Use the prct1 command to set the logging of all resource control violations at the time the task.maxlwps resource control is being setup.

  E. Use the setrct1 command to set the logging of all resource control violations for the task.max-lwps resource control.

  Correct Answer: A

  Explanation: rctladm - display and/or modify global state of system resource controls The following command activates system logging of all viola- tions of task.max-lwps. # rctladm -e syslog task.max-lwps

  # Reference: man rctladm

• Question 119:

  Which three are true of a solansl 0 branded zone running on an Oracle Solaris 11 system? (Choose three.)

  A. if there are any native non-global zones on the system that you want to migrate, these zones will be migrated into non-global zones on the Solaris 11 system

  B. The non-global zone must reside on its own ZFS dataset; only ZFS is supported

  C. The non-global zone can reside on a ZFS dataset or a UFS file system

  D. The solarisl 0 branded zone can be either a sparse or a whole root non-global zone model.

  F. When migrated from a stand-alone Solaris system to a solarisl 0 branded zone, the host ID changes to the host ID of the new machine The zone cannot be configured to use the host ID of the original system

  G. A sparse root zone cannot be converted into a solarislO branded zone.

  H. The solarisl0 branded zone cannot be an NFS server

  Correct Answer: BEH

• Question 120:

  view the Exhibit

  

  To simplify administration of a network, the decision was made to use bridging rather than routing Your

  network includes three Oracle Solaris 11 systems,

  en-tiny cib uiiuyo yiuviumy reuunuaiu pauiways.

  You previously created the bridges on each system with the following commands:

  SystemA#dladmcreate-bridge-1 netl -1 net2 bridgeA

  SystemB # dladm create-bridge -1 netl -1 net2 bndgeB

  SystemC # dladm create-bridge -1 netl -1 net2 bndgeC

  You notice that network performance is less than expected, and packets between networks X and Z are

  being forwarded by bridgeA and bridgeB, rather than being forwarded directly by bndgeC.

  Select the solution

  A. SystemC # dladm modify-bndge -p stp bridgeC

  B. SystemA # dladm modify-bridge -p stp bridgeA SystemB # dladm modify-bridge -p stp bndgeB SystemC # dladm modify-bridge -p stp bridgeC

  C. SystemC # dladm modify-bridge -p trill bridgeC

  D. SystemA # dladm modify-bridge -p trill bridgeA SystemB # dladm modify-bridge -p trill bndgeB SystemC # dladm modify-bridge -p trill bndgeC

  E. SystemC # ipadm set-prop -p forwarding=on bridgeC

  F. SystemC # dladm set-linkprop -p promiscuous=on bridgeC

  Correct Answer: E
