Question 1

Which five statements describe options available for installing the Oracle Solaris 11operating system using the installation media?

Answer Options
Correct Answer: B, C, D, E, F
Explanation

A: If the network is setup to perform automated installations, you can perform a text installation over the network by setting up an install service on the network and selecting a text installation when the client system boots.

B: After a fresh install of Solaris 11 express, only the console mode is activated.

To add Gnome, simply do :

$ sudo pkg install slim_install

This will install additional packages that are not installed by default.

D: The text installer advantages over the GUI installer include:

* In addition to modifying partitions, the text installer enables you to create and modify VTOC slices within the Solaris partition.

F: How do I upgrade my Solaris 10 or lower systems to Solaris 11?

Unfortunately, you CAN'T. There is no direct upgrade installer or other tool that will allow you to upgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10.

Incorrect answers:

E: Both installers can be used to install Oracle Solaris on the x86 platform. The text installer can also be used to install Oracle Solaris on the SPARC platform.

G: Both installers enable you to select, create, or modify disk partitions during an installation.

H: Both installers can be used to install Oracle Solaris on the x86 platform. The text installer can also be used to install Oracle Solaris on the SPARC platform.

Question 2

You are setting up a local IPS package repository on your Oracle Solaris 11 server; solans example.com

You want to point the existing local IPS publisher to the new local IPS repository located in /repo. These are the steps that you have followed:

1 Download and rsync the contents of the Oracle Solaris 11 repository ISO image to the /repo directory.

2. Configure the repository server service properties. The svcprop command displays the IPS-related properties:

pkg/inst_root astnng /repo pkg/readonly boolean true

The Is command displays the contents of the /repo directory:

#ls /repo

pkg5 repository publisher

The svcs command shows the svc:/application/pkg/server:default service is online.

The pkg publisher command still displays:

PUBLISHERTYPESTATUSURI solarisoriQinonlinehttp://DkQ.Qracle.conVsolaris/release/

Which step needs to be performed to set the local IPS publisher to the local IPS repository /repo?

Answer Options
Correct Answer: E
Question 3

A local repository is available on this system and you need to enable clients to access this repository via HTTP. The repository information is:

PUBLISHER TYPE STATUS URI

solaris origin online http://sysA.example.com

Identify two of the steps that are required to make the local repository on this server available to the client via HTTP.

Answer Options
Correct Answer: A, C
Explanation

A: Configure the Repository Server Service

To enable clients to access the local repository via HTTP, enable the application/pkg/server

Service Management Facility (SMF) service.

# svccfg -s application/pkg/server setprop pkg/inst_root=/export/repoSolaris11

# svccfg -s application/pkg/server setprop pkg/readonly=true

Question 4

The current ZFS configuration on serverA is:

Pool1

c3t2d0

c3t3d0

Pool2

c3t4d0

c3t5d0

The ZFS configuration on serverB is:

Pool1

mirror-0

c3t2d0

c3t3d0

mirror-1

c3t4d0

c3t5d0

You need to change serverA's ZFS configuration to match serverB's configuration.

Which option should you choose to modify the configuration on serverA so that it matches serverB's configuration?

Answer Options
Correct Answer: F
Explanation

We destroy both pools. Then we recreate the mirror.

Note:

zpool attach [-f] pool device new_device

Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.


Incorrect answers:

A, B: Not the correct way to use attach.

C: Just adding devices would not create a mirror.

D: Pool2 is destroyed and cannot be used in the second statement.

Note: Destroys the given pool, freeing up any devices for other use. This command tries to unmount any active datasets before destroying the pool.

E: Not the correct way to use attach.

Question 5

When setting up Automated Installer (Al) clients, an interactive tool can be used to generate a custom system configuration profile. The profile will specify the time zone, date and time, user and root accounts, and name services used for an Al client installation. This interactive tool will prompt you to enter the client information and an SC profile (XML file) will be created.

Which interactive tool can be used to generate this custom configuration?

Answer Options
Correct Answer: C
