Oracle Solaris 11 Installation and Configuration Essentials
Question No: 21
Virtualization of physical hosts to Oracle Solaris Zones is aided by .
Answer: E Explanation: Storage
ZFS is the root file system on Oracle Solaris 11 offering a superior experience in terms of manageability, scalability and data integrity. ZFS presents a pooled storage model that completely eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted bandwidth and stranded storage. Thousands of file systems can draw from a common storage pool, each one consuming only as much space as it actually needs. All
operations are copy-on-write transactions ensuring that the on-disk state is always valid.
Not A:Network Auto-Magic(NWAM)is a project to simplify and automate network configuration on Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify various network configurations to be created depending on the current network conditions. The Service Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network Auto-Magic umbrella.
Not B:Pre-Flight Checker tool which can be used to check whether apps will work without modification on Solaris 11

Question No: 22
Which command would you use, if running tools like vmstat and prstat is resulting in quot;file not foundquot; errors?
boot net: dhcp – install
Explanation: To patch a Solaris system or install a command you use pkg command.
Question No: 23
What are the two reasons that network configurations are set using svccfg, ipadm, and nscfg?
to check for proper syntax before applying a change
to comply with Sarbane-Oxley and Payment Card Industry specifications
to hide defaults fromcasualusers
because the vi(l) text editor is no longer available
Answer: C,E Explanation:
Many configuration tasks around name services have moved into the SMF in Solaris 11.
*The Service Management Facility (SMF), first introduced in Oracle Solaris 10, is a feature of the operating system for managing system and application services, and it replaces the legacy init scripting start-up mechanism common to prior releases of Oracle Solaris and other UNIX operating systems. SMF improves the availability of a system by ensuring that essential system and application services run continuously even in the event of any hardware or software failures. SMF is one of the components of the wider Oracle Solaris Predictive Self Healing capability.
*In Oracle Solaris 11, certain aspects of system configuration have changed, including the migration of several system, network, and naming services configuration to SMF.

What does the following output mean?
# eeprom | grep network-boot-arguments network-boot-arguments: data not available
OBP on this client supports WAN boot and this x86 client can be installed over the network
OBP on thisclientsupports WAN boot and this SPARC client can be installed over the network.
No network information can be set on this client to install it over the network.
BIOS on this client supports WAN boot and this SPARC client can beinstalledover the network.
OBP on this client does support WAN boot but this client#39;s data disks failed.
WANbootisnot supported and the client cannot be installed over the network.
Explanation: *WAN boot
SPARC clients of AI installation over the network must support WAN boot.
To boot over the network, AI requires WAN boot support for SPARC clients. You can check whether your client Open Boot PROM (OBP) supports WAN boot by checking whether network-boot-arguments is a valid variable that can be set in the eeprom.
If the variable network-boot-arguments is displayed, or if the command returns the output network-boot-arguments: data not available, the OBP supports WAN boot and the client can be installed over the network.
*The following command shows how to check the client OBP for WAN boot support.
# eeprom | grep network-boot-arguments network-boot-arguments: data not available
In this example, the output network-boot-arguments: data not available indicates that the client OBP supports WAN boot.

Name three Items that illustrate the business value of an integrated stack approach.
Theintegrated stack method of product development optimizes performance.
Multiple products from multiple vendors add up to an easier support structure and less fingerpointingwhen issues arise.
Support and implementation issues are minimized with an integrated stack.
An integrated stack will help to deliver faster innovation.
Toasmaller customer an integrated stack means that they need to purchaseeverything from one vendor.
Answer: A,C,D Explanation: Incorrect:
Not B:With a single vendor providing all the elements for an application platform, finger pointing is eliminated and problem resolution takes less time.
*Oracle’s product research and engineering expertise spans the entire stack – from storage,
networks, compute and operating systems, to middleware, enterprise applications and databases – and is integrated and validated to work together to take the guesswork out of deploying complex solutions.
*Oracle is the only high technology company with all the software
and hardware components to deliver an infrastructure that can transform and streamline business
operation. Indeed, Oracle’s application-to-disk stack is so well integrated and tuned that it provides less risk, better performance, and easier management for application environments
*Oracle’s end-to-end solution stack includes Oracle’s innovative servers and storage
systems, the industry’s only end-to-end virtualization portfolio, robust Oracle Solaris and Oracle Linux operating environments, Oracle Database, middleware, premier enterprise applications, and industry-leading management tools. For years, Oracle has strived to integrate, test, and certify these technologies to work together to deliver the functionality, performance, security, and reliability companies can depend on to get the job done.
*The Oracle integrated stack.

Which two commands will show or make reference to the aggregation. Immediately after creating the first aggregation?
Explanation: B:This example shows how to create a DLMP aggregation. The aggregation has three underlying datalinks.
# dladm create-aggr -m haonly -l net0 -l net1 -l net2 aggr0
# dladm show-link
LINK CLASS MTU STATE BRIDGE OVER
net0 phys 1500 up – — net1 phys 1500 up – — net2 phys 1500 up – —
aggr0 aggr 1500 up – net0, net1, net2
# dladm show-aggr
LINK MODE POLICY ADDRPOLICY LACPACTIVITY LACPTIMER
aggr0 haonly –
E:Check the status of the aggregation you just created.
# dladm show-aggr
The aggregation#39;s state should be UP.

Question No: 27
What is the expected behavior when running the following command on an x86 system?
# boot net:dhcp
The systemattempttoboot from the network, using DHCP only.
The system will fail.
The bootprocess will download the mini-root image and present a menu of choices.
The systemwill attempt to boot from the network, using DHCP ifitcan, and if not,it will try ARP.
The system will ask you if you are sure about running quot;bootquot; at this time.
Explanation: Thex86 systems cannot be told to network boot like sparc systems (ie. boot net – install).
*How to Boot a SPARC Based System From the Network 1.Become the root role.
If necessary, bring the system to the ok PROM prompt.
# init 0
Boot the system from the network without using the “install “flag. ok boot net:dhcp
Note – If you have changed the PROM setting to boot with DHCP by default, you only have to specify boot net, as shown here:
ok boot net

Question No: 28
Which three options are true of the Oracle Solaris 11 root file system?
ZFS isthe default with UFSas an option.
ZFSon rpool/ROOTis mandatory.
Mirroring isenabled by default.
Alternate bootenvironments contain only the differences from the previous boot environment.
Specificboot environments can be specified from GRUB (x86) as well as OBP (SPARC).
Explanation: A:ZFS is the default root file system.
UFS is a supported legacy file system, but it is not supported as a bootable root file system.
If your system has more than one OS installed on the system or more than one root boot environment in a ZFS root pool, you can boot from these boot environments for both SPARC and x86 platforms:
*Starting with the Solaris 10 10/08 release for a SPARC based system, you can boot a ZFS root file system in a ZFS pool. For ZFS root pools, you can list the available boot environments withthe boot command with the -L option. You can then choose a boot environment and use the OBP boot command with the -Z option to boot that boot environment.
*Starting with the Solaris 10 1/06 release for x86 based systems, a GRUB boot menu provides the interface for booting between different boot environments.
*The name originally stood for quot;Zettabyte File Systemquot;but today does not stand for anything.
Not C: Mirroring is not enabled by default. Not D:Alternate bootenvironments
If you want to create a backup of an existing boot environment, for example, prior to modifying the original boot environment, you can use the beadm command to create and mount a new boot environment that is a clone of your active boot environment. This clone is listed as an alternate boot environment in the GRUB menu for x86 systems or in the boot menu for SPARC systems.
Question No: 29
The command quot;beadm create -a solaris-testquot; will .
create and automatically boot the solaris-test boot environment
create and activate the solaris-test boot environment but not reboot
create an archive of the solaris-test boot environment
will not create a new boot environment without further information
will only activate a previously defined boot environment named solaris-test
Explanation: The beadm create command has the following options, where BeName specifies the name of the boot environment to be created.
Syntax: beadm create [-a] [-d description] [-e non-activeBeName | BeName@snapshot] [-o property=value]…[-p zpool] BeName
-a – Activate the newly created boot environment upon creation. The default is to not activate the newly created boot environment.

Question No: 30
Which three ZFS options may be combined to provide zones storage with data security and a minimal storage footprint?
Answer: A,D,E Explanation: A:
*Oracle Solaris 11 adds transparent data encryption functionality to ZFS. All data and file system metadata (such as ownership, access control lists, quota information, and so on) are encrypted when stored persistently in the ZFS pool.
*A very simple example of using ZFS encryption is as follows:
#zfs create -o encryption=on rpool/export/project Enter passphrase for #39;rpool/export/project#39;:
#zfs create rpool/export/project/A
#zfs create rpool/export/project/A/design
#zfs create rpool/export/project/B
D:compression=onreduces storate footprint
E:If you want to allow the filesystem to be managed inside the zone, use the zfs zoned=on option when creating or modifying the filesystem.
