NEW QUESTION 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

Answer: BCD

Explanation: 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 right on 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.

NEW QUESTION 2
You are installing the Solaris 11 Operation System by using the Text Installer. A panel
prompts you to create a root password and a user account.
Which four describe your options for completing this panel of the Installation?

• A. Creating a user account is optional.
• B. The root password must be set and cannot be blank.
• C. The root password can be left blank.
• D. If you provide a username, that user is assigned the root role.
• E. If you provide a username, that user is given root privileges.
• F. If you provide a username, root is an account rather than a role and is set to expire immediately.
• G. If you do not provide a username, root is an account rather than a role and is set to expire immediately.

Answer: ABDG

Explanation: A: You are not required to create a user account. B: You must create a root password.
D: If you create a user account in this panel, you need to provide both the user's password and a root password.
In this case, root will be a role assigned to the user.
G: If you do not create a user account, you still need to provide a root password. In this case, root will be a regular user.

• E. By default, the pkg update command always updates Solaris 11 to the first SRU that was released after the Current SRU.
• F. The pkg update command can only be performed while running in the single-user milestone.

Answer: BC

NEW QUESTION 5
You have been asked to troubleshoot the initial configuration of a virtual network connecting two local zones with the outside world.
View the exhibit.

The command
dladm create-vnic -1 vswitch192.168.1 vnic1 fails with the error
dladm: invalid link name ‘vswitch192.168.1’ What is the reason for this error?

• A. The name vswitch192.168.1 is not legal.
• B. The zone must be specified withdladm create-vnic -z zone3 vnic1.
• C. The virtual interface must be specified withdladm create-vnic -z zone3 vnic1.
• D. The virtual interface must be created withipadm create-vnic -1 switch192.168.1.
• E. The virtual switch must be created first withdladm create -etherstub vswitch192.168.1.

Answer: E

Explanation: There is no data-link named vswitch192.168. We need to create an etherstub first.
See Note and example below for details.
Note: Create a VNIC in the system's global zone.
# dladm create-vnic -l data-link vnic-name
data-link is the name of the interface where the VNIC is to be configured.
-l link, --link=link
link can be a physical link or an etherstub.
vnic-name is the name that you want to give the VNIC.
For example, to create a VNIC named vnic0 on interface e1000g0, you would type the following:
# dladm create-vnic -l e1000g0 vnic0
Example: Creating a Virtual Network Without a Physical NIC First, create an etherstub with name stub1:
# dladm create-etherstub stub1
Create two VNICs with names hello0 and test1 on the etherstub. This operation implicitly creates a virtual switch connecting hello0 and test1.
# dladm create-vnic -l stub1 hello0
# dladm create-vnic -l stub1 test1

NEW QUESTION 6
Identify three options that describe the new Oracle Solaris 11 zone features.

• A. There are boot environments for zones.
• B. Administrators can delegate common administration tasks by using RBAC.
• C. Oracle Solaris 11 supports Solaris 8, 9, and 10 branded zones.
• D. You can migrate a physical Solaris 10 system and its non-global zones to a solaris10 branded zone running on an Oracle Solaris 11 system.
• E. It is possible to change the host ID of a zone.

Answer: ABD

Explanation: A: The beadm utility includes support for creating and administering non-global zone boot environments.
Note: A boot environment is a bootable instance of the Oracle Solaris operating system image plus any other application software packages installed into that image. System administrators can maintain multiple boot environments on their systems, and each boot environment can have different software versions installed.
B: Role-based access control (RBAC) is a security feature for controlling user access to tasks that would normally be restricted to the root role. By applying security attributes to processes and to users, RBAC can divide up superuser capabilities among several administrators.

NEW QUESTION 8
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.
Choose the three options that describe the requirements for using AI.

• 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 9
You need to set up an Oracle Solaris 11 host as an iSCSI target so that the host's disk can be accessed over a storage network. The disk device is c3t4d0.
Which six options describe the steps that need to be taken on this host to enable an iSCSI target?

• A. Create a ZFS file system named iscsi/target.
• B. Create a zpool named iscsi with disk device c3t4d0
• C. Create zfs volume named iscsi/target.
• D. Use the stmfadm command to create a LUN using /dev/zvol/rdsk/iscsi/target.
• E. Use the stmfadm command to create a LUN using iscsi/target.
• F. Use the stmfadm command to make the LUN viewable.
• G. Use the stmfadm command to make the volume viewable.
• H. Enable the svc:/network/iscsi/target:default Service.
• I. Use the itadm command to create the iSCSI target.

Answer: BCDFHI

Explanation: How to Create an iSCSI LUN
The following steps are completed on the system that is providing the storage device.
Example: target# zpool create sanpool mirror c2t3d0 c2t4d0 (C)2. Create a ZFS volume to be used as a SCSI LUN. (D)3. Create a LUN for the ZFS volume.
Example:
target# stmfadm create-lu /dev/zvol/rdsk/sanpool/vol1
Logical unit created: 600144F0B5418B0000004DDAC7C10001
4. Confirm that the LUN has been created.
Example
target# stmfadm list-lu
LU Name: 600144F0B5418B0000004DDAC7C10001
(F) 5. Add the LUN view.
This command makes the LUN accessible to all systems.
target# stmfadm add-view 600144F0B5418B0000004DDAC7C10001 How to Create the iSCSI Target
This procedure assumes that you are logged in to the local system will contains the iSCSI target.
Note: The stmfadm command manages SCSI LUNs. Rather than setting a special iSCSI property on the ZFS volume, create the volume and use stmfadm to create the LUN.
(H) 1. Enable the iSCSI target service.
target# svcadm enable -r svc:/network/iscsi/target:default
(I) 2. Create the iSCSI target.
target# itadm create-target

NEW QUESTION 10
You create a flash archive of the Solaris 10 global zone on the serves named sysA. The archive name is s10-system.flar, and it is stored on a remote server named backup_server.
On sysA, you create a Solaris 10 branded zone named s10-zone.
You want to use the flash archive, located On" /net/bactup_servers/10-system.flar, to install the Operating system in the s10-zone zone.
Which command do you choose to install the s10-system.flar archive in the Solaris 10 branded zone (s10-zone)?

• A. zoneadm -z s10 -zone install - a /net/backup_server/s10-system.flar -u
• B. zonecfg -z s10 -zone install - a /net/backup_server/s10-system.flar -u
• C. zoneadm - z s10 -zone clone - s /net/backup_server/s10-system.flar
• D. zone cfg - a s10-zone create - t SUNWsolaris10</net/backup_server/s10-system.flar
• E. zonecfg -z s10-zone install -f /net/backup/backup_server/s10-system.flar

Answer: A

Explanation: The zoneadm command is the primary tool used to install and administer non-global zones. Operations using the zoneadm command must be run from the global zone on the target system.
How to Install the solaris10 Branded Zone
A configured solaris10 branded zone is installed by using the zoneadm command with the install subcommand.
Example: global# zoneadm -z s10-zone install -a /net/machine_name/s10-system.flar –u

NEW QUESTION 11
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.

NEW QUESTION 15
The following image properties are displayed on your system:

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

• A. All package operations are performed in a new BE set as active on the next boot.
• B. Do not create a new B
• C. The install, update, uninstall, or revert operation is not performed if a new BE is required.
• D. If a BE is created, do not set it as the active BE on the next boot
• E. A reboot is required for all package operations
• F. A reboot is not required after a package operation.
• G. For package operations that require a reboot, this policy creates a new BE set as active on the next boot.

Answer: DF

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.

NEW QUESTION 16
Which network protocol is responsible for routing packets from one network to another?

• A. TCP

You display the IP interface information with ipmpstat -i.
Which two characteristics are indicated by characters that may be included in the FLAGS column?

• A. default route
• B. IP forwarding enabled IS
• C. allocated to global zone
• D. unusable due to being inactive
• E. nominated to send/receive IPv4 multicast for its IPMP group

Answer: DE

Explanation: FLAGS
Indicates the status of each underlying interface, which can be one or any combination of the following:
(D) d indicates that the interface is down and therefore unusable.
(E) M indicates that the interface is designated by the system to send and receive IPv6 multicast traffic for the IPMP group.
Note:
i indicates that the INACTIVE flag is set for the interface. Therefore, the interface is not used to send or receive data traffic.
s indicates that the interface is configured to be a standby interface.
m indicates that the interface is designated by the system to send and receive IPv4 multicast traffic for the IPMP group.
b indicates that the interface is designated by the system to receive broadcast traffic for the IPMP group.
h indicates that the interface shares a duplicate physical hardware address with another interface and has been taken offline. The h flag indicates that the interface is unusable.

NEW QUESTION 19
In a default standalone installation of Oracle Solaris 11, what is the default minimum length in characters of a user password, and where is the minimum password length defined?

• A. Default minimum length is 8, and is defined in /etc/default/password.
• B. Default minimum length is 6, and is defined in /etc/default/password.
• C. Default minimum length is 8, and is defined in /etc/shadow.
• D. Default minimum length is 6, and is defined in /etc/shadow.
• E. Default minimum length is 8, and is defined in /usr/sadm/defadduser.
• F. Default minimum length is 6, and is defined in /usr/sadm/defadduser.
