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.
Answer: C
Explanation: 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.

-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.
NEW QUESTION 2
Which three options describe the purpose of the zonep2vchk command?
Answer: CDE
Explanation: zonep2vchk
- check a global zone's configuration for physical to virtual migration into non-global zone
The zonep2vchk utility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone.
The p2v process involves archiving a global zone (source), and then installing a non-global zone (target) using that archive
Zonep2vchk serves two functions. First, it can be used to report issues on the source which might prevent a successful p2v migration. Second, it can output a template zonecfg, which can be used to assist in configuring the non-global zone target.
Zonep2vchk can be executed on a Solaris 10 or later global zone. To execute on Solaris 10, copy the zonep2vchkutility to the Solaris 10 source global zone.
When run on Solaris 10, a target release of S11 can be specified, which will check
for p2v into a Solaris 10 Branded zone.

A change in your company’s security policy now requires an audit trial of all administrators assuming the sysadm role, capturing:
There are two command necessary to accomplish this change. One is a rolemod command. What is the other?
Answer: B
Explanation: 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.
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
# 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.

NEW QUESTION 12
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?
Answer: E
Explanation: 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.
NEW QUESTION 13
When setting up Automated Installer (AI) clients, an interactive tool can be used to generate a custom system configuration profile. The profile will specify the time zone, data and time, user and root accounts, and name services used for an AI client installation. This interactive tool will prompt you to enter the client information and an SC profile (XML) will be created.
Which interactive tool can be used to generate this question configuration?
Answer: B
Explanation: Use the installadm set-criteria command to update the client criteria associated with an AI manifest that you already added to a service using installadm add-manifest.
Use the installadm add-manifest command to add a custom AI manifest to an install service.
The value of manifest is a full path and file name with .xml extension. The manifest file contains an AI manifest (installation instructions). The manifest file can also reference or embed an SC manifest (system configuration instructions).
NEW QUESTION 14
Given:
file1 and file2 are text files. dir1 and dir2 are directories.
Which two commands will be successful?
Answer: CF
Explanation: C: Here the wildcard character ? is used (Matches any single character). file1 and file2 will be copied into dir1
F: the two files file1 and file2 are copied into directoy dir1. Note: cp - copy files and directories
Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.
Cp has three principal modes of operation. These modes are inferred from the type and count of arguments presented to the program upon invocation.
* When the program has two arguments of path names to files, the program copies the contents of the first file to the second file, creating the second file if necessary.
* When the program has one or more arguments of path names of files and following those an argument of a path to a directory, then the program copies each source file to the destination directory, creating any files not already existing.
* When the program's arguments are the path names to two directories, cp copies all files in the source directory to the destination directory, creating any files or directories needed. This mode of operation requires an additional option flag, typically r, to indicate the
recursive copying of directories. If the destination directory already exists, the source is copied into the destination, while a new directory is created if the destination does not exist.
NEW QUESTION 15
You need to install the solaris-desktop group package. Which command would you use to list the set of packages included in that software group?
