NEW QUESTION 1
In a fresh installation of Oracle Solaris 11, default datalinks are named with a genetic naming convention, and they increment as you add interfaces. What is the default name?
Answer: B
Explanation: When you install this Oracle Solaris release on a system for the first time, Oracle Solaris automatically provides generic link names for all the system's physical network devices. This name assignment uses the net# naming convention, where the # is the instance number. This instance number increments for each device, for example, net0, net1, net2, and so on.
Note:
Network configuration in Oracle Solaris 11 includes
* Generic datalink name assignment – Generic names are automatically assigned to datalinks using the net0, net1, netN naming convention, depending on the total number of network devices that are on the system
NEW QUESTION 2

Explanation: A: Conditional and system locations can be manually activated, which means that the location remains active until explicitly disabled.
D: A location comprises certain elements of a network configuration, for example a name service and firewall settings, that are applied together, when required. You can create multiple locations for various uses. For example, one location can be used when you are connected at the office by using the company intranet. Another location can be used at home when you are connected to the public Internet by using a wireless access point. Locations can be activated manually or automatically, according to environmental conditions, such as the IP address that is obtained by a network connection.

Version: 5.2.17
Build Release: 5.11
Branch: 0.175.0.0.0.1.530
Packaging Date: Wed Oct 12 14:01:41 2011
Size: 44.47 MB
FMRI: pkg://solaris/web/php-52@5.2.17, 5.11-0.175.0.0.0.1.530:20111012T140141Z

installed packages in the image.
With -l, use the data available from locally installed packages. This is the default.

NEW QUESTION 7
You have been asked to do an orderly shutdown on a process with a PID of 1234, with the kill command.
Which command is best?
Answer: B
Explanation: On POSIX-compliant platforms, SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.
SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process, but unlike the SIGKILL signal, it can be caught and interpreted (or ignored) by the process. Therefore, SIGTERM is akin to asking a process to terminate nicely, allowing cleanup and closure of files. For this reason, on many Unix systems during shutdown, init issues SIGTERM to all processes that are not essential to powering off, waits a few seconds, and then issues SIGKILL to forcibly terminate any such processes that remain.

NEW QUESTION 11
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.
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.
# 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.

NEW QUESTION 14
You need to make sure that all of the software packages on your server are up to date. Without installing any updates, which two commands would display .my software updates that are available in the default Oracle repository?
Answer: AD
Explanation: A: the pgk list command display a list of packages in the current image, including state and other information. By default, package variants for a different architecture or zone type are excluded.
D: pkginfo displays information about software packages that are installed on the system (with the first synopsis, with -l) or that reside on a particular device or directory (with the second synopsis, with -r).
Without options, pkginfo lists the primary category, package instance, and the names of all completely installed and partially installed packages. It displays one line for each package selected.
With -r, retrieve the data from the repositories of the image's configured publishers. Note that you must specify one or more package patterns in this case.

NEW QUESTION 16
You have edited /etc/profile to include the lines: dennis_says=hello
export dennie_says
You have also edited /etc/skel/local.profile to include the line: dennis_says=world
You now create a new user account brian, and specify use of the bash shell. When brian logs in and enters
Echo $dennis_says
What will he see, and why?
Answer: A
Explanation: The $HOME/.profile file is an initialization file that is executed after the /etc/profile when logging in to the Bourne or Korn shell. The file contains user preferences for variable settings. If the ENV variable is set to .kshrc, the .kshrc file executes every time a new shell
begins execution. The $HOME/.profile is copied from the /etc/skel/local.profile file by the Administration Tool when creating a new account.
Note: /etc/skel/local.profile
Per-system configuration file for sh/ksh/ksh93/bash login sessions, installed for new users
