Oracle Solaris 11 System Administration

Question No: 21 – (Topic 1)

Choose three options that describe the features associated with a Live Media installation.

  1. does not allow the root user to log in to the system directly from the console (or any terminal)

  2. provides a quot;hands freequot; installation

  3. installs the desktop based packages

  4. can be used to install only x86 platforms

  5. installs the server-based set of packages only

  6. allows both automatic and manual configuration of the network

  7. installs both the server-based and desktop-based package

Answer: B,C,D Explanation:

The graphical installer is officially known as the quot;Live Media.quot; This means that Oracle Solaris can be booted into RAM,causing zero impact on your existing operating system. After it is loaded,you are free to experiment with Oracle Solaris to determine whether it is something you would like to install to your system.

You can download Oracle Solaris 11 Live Media for x86,which is an approximately 800 MB image file,and use a DVD burner to create the disk,or you can use the ISO image directly in a virtual machine or through the Oracle Integrated Lights Out Manager (ILOM) Remote Console.

The Live Media is not intended for long-term use. For example,any changes that you make to the system are lost when the system is shut down. Therefore,the next logical step is to install Oracle Solaris on the system,which the Live Media makes easy by placing an Install Oracle Solaris icon righton the desktop. But before we head down that road,let#39;s step back a bit and consider the installation options.

Note: The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11 environment without installing it on a system. The system boots off the media directly allowing administrators to start the installer should they choose to install it to a system.

Identify the correct description of an IPS image.

  1. An ISO image of the Solaris media DVD

  2. An IPS repository

  3. Adepot location or source where Solaris packages can be installed from

  4. Alocation where packages can be installed,for example,your Solaris instance

Answer: D Explanation:

An image is a location where packages can be installed. An image can be one of three types:

  • Full images are capable of providing a complete system.

  • Partial images are linked to a full image (the parent image),but do not provide a complete system on their own.

  • User images contain only relocatable packages.

    Question No: 24 – (Topic 1)

    How are operating system updates distributed in the Oracle Solaris 11 environment?

    1. Updates are only available to customers with an active support contract. The updates are distributed through the My Oracle Support web portal and installed in a central location. All software packages are then updated manually from the command line using the smpatch command.

    2. Patches are download from http: //support.oracle.com either automatically or manually. All software packages are then updated manually from the command line using the smpatch or patchadd commands.

    3. Software updates are published as packages to a repository. All software packages are then updated manually from the command line using the pkg command.

    4. Software updates,published as packages to an OS image. All software packages are then updated manually from the command line using the pkg command.

    Answer: C Explanation:

  • Updating all of the packages on your installed system – To update all of the packages on your system that have available updates,use the pkg update command,as follows:

    # pkg update

    Running this command updates packages that you might not otherwise consider updating,for example,kernel components and other low-level system packages.

  • Adding or updating individual packages – To add individual software packages,use the pkg install command. Any dependent packages are also updated at the same time.

  • install package updates that deliver fixes- A pkg update operation might include bug fixes,so the operation is similar to applying a specific patch or patches in previous Oracle Solaris releases.

    Note: The IPS interfaces first check for updates for currently installed packages before retrieving them via the network. By default,interfaces check repository catalogs in the following locations:

  • The default installation repository at pkg.oracle.com/solaris/release.

  • The support repository in My Oracle Support. This repository is restricted to users with Oracle Solaris 11 Express support contracts,and it contains packages with the latest bug fixes. For this reason,a support contract must be purchased for production deployments.

    Question No: 26 – (Topic 1)

    The following image properties are displayed on your system:

    Ensurepass 2018 PDF and VCE

    Which two options describe the boot environment policy property that is currently set for this image?

    1. All package operations are performed in a new BE set as active on the next boot.

    2. Do not create a new BE. The install,update,uninstall,or revert operation is not performed

      if a new BE is required.

    3. If a BE is created,do not set it as the active BE on the next boot

    4. A reboot is required for all package operations

    5. A reboot is not required after a package operation.

    6. For package operations that require a reboot,this policy creates a new BE set as active on the next boot.

    Answer: D,F Explanation:

    Image properties described below.

  • be-policy

  • Specifies when a boot environment is created during packaging operations. The following values are allowed:

    / default

    Apply the default BE creation policy: create-backup.

    / always-new (D,F)

    Require a reboot for all package operations (D) by performing them in a new BE set as active on the next boot (F). A backup BE is not created unless explicitly requested.

    This policy is the safest,but is more strict than most sites need since no packages can be added without a reboot.

    Question No: 28 – (Topic 1)

    User1 is attempting to assist user2 with terminating user2#39;s process 1234. User1 entered the following: kill -9 1234

    Why does the process continue to run?

    1. You can kill a process only if you are root.

    2. You can kill only a process that you own.

    3. You can kill the process only with the pkill command.

    4. You need to kill the process with a stronger kill signal.

    Answer: B Explanation: Kill -9

    Kill (terminates without cleanup)

    Only works if issued by process owner or super user (root) The program cannot respond to this signal; it must terminate

    Note: Unix provides security mechanisms to prevent unauthorized users from killing other processes. Essentially,for a process to send a signal to another,the owner of the signaling process must be the same as the owner of the receiving process or be the superuser.

    Question No: 29 – (Topic 1)

    You are currently working in both your home directory and the system directory /tmp. You are switch back and forth with full path names. Which pair of cd commands will provide you with a shortcut to switch between these two locations?

    1. cd ~ and cd –

    2. cd and cd.

    3. cd ~ and cd

    4. cd * and cd . .

    Answer: A Explanation:

    In the Bourne Again,C,Korn,TC,and Z shells,the tilde (~) is used as a shortcut for specifying your home directory.

    cd –

    It#39;s the command-line equivalent of the back button (takes you to the previous directory you were in).

    Note:

    To make certain that you are in your home directory,type the cd (change directory) command. This command moves you to your home (default) directory.
