  H. The LiveCD installer can be used for SPARC or x86 platforms.
  B. The text Installer does not install the GNOME desktop. The GNOME desktop package must he added after you have installed the operating system.
  C. The LiveCD Installation cannot be used to install multiple instances of Oracle Solaris.
  D. The LiveCD installer cannot be used if you need to preserve a specific Solaris Volume Table of Contents (VTOC) slice in your current operating system.
  E. The LiveCD Installer is for x86 platforms only.
  F. The GUI installer cannot be used to upgrade your operating system from Solaris 10.

  A: If the network is setup to perform automated installations, you can perform a text installation over the network by setting up an install service on the network and selecting a text installation when the client system boots.

  B: After a fresh install of Solaris 11 express, only the console mode is activated. To add Gnome, simply do :

  $ sudo pkg install slim_install

  This will install additional packages that are not installed by default.

  D: The text installer advantages over the GUI installer include:

  * In addition to modifying partitions, the text installer enables you to create and modify VTOC slices within the Solaris partition.

  F: How do I upgrade my Solaris 10 or lower systems to Solaris 11?

  Unfortunately, you CAN'T. There is no direct upgrade installer or other tool that will allow you to upgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10.

• Question 24:

  View the Exhibit and review the zpool and ZFS configuration information from your system.

  A. zpool split pool1 pool2 c4t0d0 c4t2d0 zpool import pool2 zfs set mountpoint = /dev_data pool2/prod_data
  B. zpool detach pool1 pool2 zpool attach pool2 zfs set mountpoint=/dev_data pool2/prod_data
  C. zpool split pool1/prod_data -n pool2/dev_data zfs set mountpoint = /dev_data pool2/prod_data
  D. zpool split pool1 pool2 c4t0d0 c4t2d0 zpool import pool2
  D. zpool split pool1 pool2 c4t0d0 c4t2d0 zpool import pool2

  ---

  In this Solaris release, you can use the zpool split command to split a mirrored storage pool, which detaches a disk or disks in the original mirrored pool to create another identical pool. After the split operation, import the new pool.

• Question 26:

  B. auditconfig -setpolicy +argv

  Audit Significant Events in Addition to Login/Logout (see step 2 below) Use this procedure to audit administrative commands, attempts to invade the system, and other significant events as specified by your site security policy.

  Audit all uses of privileged commands by users and roles. For all users and roles, add the AUE_PFEXEC audit event to their preselection mask.

  # usermod -K audit_flags=lo,ps:no username # rolemod -K audit_flags=lo,ps:no rolename Record the arguments to audited commands. # auditconfig -setpolicy +argv 3- Record the environment in which audited commands are executed. # auditconfig -setpolicy +arge

  Note: [-t] -setpolicy [+|-]policy_flag[,policy_flag ...] Set the kernel audit policy. A policy policy_flag is literal strings that denotes an audit policy. A prefix of + adds the policies specified to the current audit policies. A prefix of - removes the policies specified from the current audit policies. No policies can be set from a local zone unless the perzone policy is first set from the global zone.

• Question 30:

  The core dump configuration in your non global zone is

  

  A user is running a process in a non-global zone (testzone) and the process crashes. The process information is:

  user126632618017:46:42pts/20:00/usr/bin/bash

  When the user's process crashes in testzone, a non-global zone, where will the core dump be saved?

  A. The file will be stored in the non-global zone's directory: /var/core/pprocess/core.hash.2663.
  B. The file will be saved in the global zone's directory: /var/core/core.bash.2663.
  C. A core file cannot be generated in a non-global zone because it shares the kernel with the global zone.
  D. The file will be stored in the global zone's directory: /var/core/pprocess/core.bash.2663.
  E. The file will be saved in non-global zone's directory: /var/core/core.bash.2663
  E. The file will be saved in non-global zone's directory: /var/core/core.bash.2663

  ---

  The line init core file pattern: /var/core/core.%f.%p will be used for the non-global process to determine the destination of the dump file.

  Note: When a process is dumping core, up to three core files can be produced: one in the per-process location, one in the system-wide global location, and, if the process was running in a local (non-global) zone, one in the global location for the zone in which that process was running.
