  • A. You can create only one manifest per install servic
  • B. If you need more than one manifest create multiple install services.
  • C. If two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS, then create two AI manifests and a single install service.
  • D. You need a separate install service for each different client architecture that you plan to install, and for each different version of the Oracle Solaris 11 OS that you plan to install on client systems.
  • E. If two client machines have different architectures and need to be installed with different versions of the Oracle Solaris 11 OS, then create two AI manifests and two install services.
  • F. The install server needs to be able to access an Oracle Solaris Image Packaging System (IPS) software package repository; the clients do not.
  • G. The install server can be either an x86 machine or a SPARC machine.

Answer: BEF

Explanation:
B (not A, not D, Not C): If two client machines need to be installed with the same version of the Oracle Solaris 11 OS but
need to be installed differently in other ways, then create two AI manifests for the AI install service. The different AI manifests can specify different packages to install or a different
slice as the install target, for example.
Note: An AI manifest provides installation instructions.
The AI manifest specifies one or more IPS package repositories where the client retrieves the packages needed to complete the installation. The AI manifest also includes the names of additional packages to install and information such as target installation device and partition information.
F: The install server can be either an x86 machine or a SPARC machine.

NEW QUESTION 11
You have a ticket from a new user on the system, indicating that he cannot log in to his account. The information in the ticket gives you both the username and password. The ticket also shows that the account was set up three days ago.
As root, you switch users to this account with the following command: su – newuser
You do not get an error message.
You then run 1s -1a and see the following files:
local1.cshrc local1.login local1.profile .bash_history .bashrc .profile
As root, you grep the /etc/passwd file and the /etc/shadow file for this username, with these results:
/etc/passwd contains newuser:x:60012:10:/home/newuser:/usr/bin/bash
/etc/shadow contains newuser:UP: : : : :10: : As root, what is your next logical step?

  • A. Usermod –f 0
  • B. passwd newuser
  • C. mkdir /home/newuser
  • D. useradd –D

Which best describes the svc:/system/boot-config service?

  • A. It is used to change the milestone on a system.
  • B. It is used to set the default run level of the system.
  • C. It provides the parameters used to set the system to automatically perform a fast or slow reboot.
  • D. When the service is enabled, the system performs a fast reboot by default; when it is disable the system performs a slow reboot by default.

Answer: C

Explanation:
Starting with the Oracle Solaris 11 Express release, Fast Reboot is supported on the SPARC platform, as well as the x86 platform. On both platforms, this feature is controlled by the SMF and implemented through a boot configuration service, svc:/system/boot- config. The boot-config service provides a means for setting or changing the default boot configuration parameters.
The fastreboot_default property of the boot-config service enables an automatic fast reboot of the system when either the reboot or the init 6 command is used. When the config/fastreboot_default property is set to true the system automatically performs a fast reboot, without the need to use the reboot -f command. By default, this property's value is set to false on the SPARC platform and to true on the x86 platform.
