Q141. - (Topic 1)
Choose three options that describe the features associated with a Live Media installation.
A. does not allow the root user to log in to the system directly from the console (or any terminal)
B. provides a "hands free" installation
C. installs the desktop based packages
D. can be used to install only x86 platforms
E. installs the server-based set of packages only
F. allows both automatic and manual configuration of the network
G. installs both the server-based and desktop-based package
The graphical installer is officially known as the "Live Media." 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'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.

You have set up the task.max-lwps resource control on your Solaris 11 system.
Which option describes how to configure the system so that syslogd notifies you when the resources control threshold value for the task.max-lwps resource has been exceeded?
A. Use the rctladm command to enable the global action on the task.max-lwpa resource control.
B. Modify the /etc/syslog.conf file to activate system logging of all violations of task.max-lwps and then refresh then svc: /system/system-log:default service.
C. Activate system logging of all violations of task.max-lwpp in the /etc/rctldm.conf file and then execute the rctladm-u command.
D. Use the prct1 command to set the logging of all resource control violations at the time the task.max-lwps resource control is being setup.
E. Use the setrct1 command to set the logging of all resource control violations for the task.max-lwps resource control.
rctladm - display and/or modify global state of system resource controls
The following command activates system logging of all viola-tions of task.max-lwps.
# rctladm -e syslog task.max-lwps #

A. Run arp -a on all servers.
B. Confirm that the router is working.
C. Confirm that the power light of the network switch is on.
D. Confirm that the physical network connections are intact.
E. On Server A and C,run tranceroute –n server.
F. On Server B,run tranceroute –n servera and tranceroute –n serverc.
Check the physical connection.
Q144. - (Topic 2)
You want to deploy Oracle Solaris 11 with the Automated Installer (AI). You need to make sure that your server and network meet the requirements for using AI.
Identify two requirements for using AI.
A. You should set up DHCP. The DHCP server and AI install server can be the same machine or two different machines.
B. You can create only one manifest per install service. If you need more than one manifest,you should create multiple install services.
C. The minimum requirement to operate as an AI install server is 1 GB of memory.
D. If two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS,then you should create two AI manifests and a single install service.
A: An automated installation of a client over the network consists of the following high-level
Step 1. The client system boots over the network and gets its network configuration and the
location of the install server from the DHCP server.
Step 2: The install server provides a boot image to the client.
D: 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.
Q145. - (Topic 1)
Which two options are characteristics of a fast reboot?
A. A fast reboot bypasses grub.
B. A fast reboot cannot be used after a system panic on the x86 platform.
C. A fast reboot can only be executed on the SPARC platform when the config/fastreboot_default property for the svc:/system/boot-config:default service is set to true.
D. A fast reboot uses an in-kernel boot loader to load the kernel into memory.
E. A fast reboot is the default on all platforms.
C: To change the default behavior of the Fast Reboot feature on the SPARC platform,so that a fast reboot is automatically performed when the system reboots,see below.
The following example shows how to set the property's value to true on the SPARC platform,so that a fast reboot is initiated by default:
# svccfg -s "system/boot-config:default" setprop config/fastreboot_default=true # svcadm refresh svc:/system/boot-config:default
D: Fast Reboot implements an in-kernel boot loader that loads the kernel into memory and
then switches to that kernel.
The firmware and boot loader processes are bypassed,which enables the system to reboot
The Fast Reboot feature is managed by 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. When the config/fastreboot_default property is set to true,the system performs a fast reboot automatically,without the need to use the reboot -f command. This property's value is set to true on the x86 platform. For task-related information,including how to change the default behavior of Fast Reboot on the SPARC platform,see Accelerating the Reboot Process on an x86 Based System.
Note: One new feature,called Fast Reboot,will allow the system to boot up without doing the routine set of hardware checks,a move that can make system boot times up to two-and-a-half times faster,Oracle claimed. This feature can be handy in that an administrator applying a patch or software update across thousands of Solaris deployments can reboot them all the more quickly.

Your server has a ZFS storage pool that is configured as follows:
The server has two spare 146-GB disk drives: c3t5d0 c3t6d0
You need to add more space to the pool1 storage pool. Which command would add more mirrored storage to the pool1 storage pool?
A. zpool add pool1 mirror c3t5d0 c3t6d0
B. zpool attach pool1 mirror c3t5d0 c3t6d0
C. zpool attach pool1 c3r3d0 c3r5d0; zpool attach pool1 c3r4d0 c3r6d0
D. zpool add pool1 c3r3d0 c3r5d0; zpool add pool1 c3r4d0 c3r6d0
Q148. - (Topic 1)
You have installed software updates to a new boot environment (BE) and have activated that the booting to the new BE,you notice system errors. You want to boot to the last known good configuration.
Which option would you use on a SPARC system to boot to the currentBE boot environment?
A. boot –L currentBE
B. boot –Z rpool/ROOT/currentBE
C. boot –a Enter the currentBE dataset name when prompted.
D. boot rpool/ROOT/currentBE
E. boot –m currentBE
F. beadm activate currentBE
You can change an inactive boot environment into an active boot environment. Only one boot environment can be active at a time. The newly activated boot environment becomes the default environment upon reboot.
How to Activate an Existing Boot Environment
1. Use the following command to activate an existing,inactive boot environment: beadm activate beName
beName is a variable for the name of the boot environment to be activated.
Note the following specifications.
beadm activate beName activates a boot environment by setting the bootable pool property,bootfs,to the value of the ROOT dataset of the boot environment that is being activated.
beadm activate sets the newly activated boot environment as the default in the menu.lst file.
The newly activated boot environment is now the default on the x86 GRUB menu or
SPARC boot menu.

Select the five tasks that need to be performed on the Automated Installer (AI) install server before setting up the client.
A. Create a local IPS repository on the AI Install server and start the repository server service,the publisher origin to the repository file.
B. Set up a IP address on the AI install server.
C. The DHCP server must be enabled on the install server and must provide the DHCP service for the clients.
D. DHCP must be available on the network for the Install server and the clients,but the install server does not need to be the DHCP server.
E. Download the AI boot image. The image must be the same version as the Oracle Solaris OS that you plan to install on the client.
F. Download the text install image into the IPS repository.
G. Install the AI installation tools.
H. Create the AI install service. Specify the path to the AI network boot image ISO file and the path where the AI net image ISO file should be unpacked.
I. Create the AI install service. Specify the path to the AI network boot image ISO file and the path to the IPS repository.
B: Configure the AI install server to use a static IP address and default route..
D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server for use with AI. The DHCP server must be able to provide DNS information to the systems to be installed.
E: An automated installation of a client over the network consists of the following high-level
The client system boots over the network and gets its network configuration and the
location of the install server from the DHCP server.
The install server provides a boot image to the client.
Characteristics of the client determine which installation instructions and which system
configuration instructions are used to install the client.
The Oracle Solaris 11 OS is installed on the client,pulling packages from the package
repository specified by the installation instructions in the AI install service.
G: Install the AI tool set.
Use the.installadm create-service.command to create an AI install service. Give the service
a meaningful name,and specify the path where you want the service created. Specify the
source of the network boot image (net image) package or ISO file.
installadm create-service [-n svcname] [-s FMRI_or_ISO] [-d imagepath]
-d.imagepath The.imagepath.is the location of the new install service. The.install-image/solaris-auto-install.package is installed to this location,or the specified ISO file is expanded at this location.
Q150. - (Topic 1)
Which files must be edited in order to set up logging of all failed login attempts?
This procedure captures in a syslog file all failed login attempts.
Set up the /etc/default/login file with the desired values for SYSLOG and SYSLOG_FAILED_LOGINS Edit the /etc/default/login file to change the entry. Make sure that SYSLOG=YES is uncommented.
Create a file with the correct permissions to hold the logging information. Create the authlog file in the /var/adm directory.
Edit the syslog.conf file to log failed password attempts. Send the failures to the authlog file.
