Questions # 31:

Which command should you choose to display the current parameters for the FSS scheduler?

Options:

dispadmin - c FSS

prionctl -c FSS

dispadmin -c FSS -g

priocntl -c FSS -g

Answer

Explanation

The dispadmin command displays or changes process scheduler parameters while the system is running.

-c class

Specifies the class whose parameters are to be displayed or changed. Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter-active class, FSS for the fair-share class, and FX for the fixed-priority class. The time-sharing and inter-active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.

-g

Gets the parameters for the specified class and writes them to the standard output.

[Reference: man dispadmin]

Questions # 32:

Which three options describe the purpose of the zonep2vchk command?

Options:

Used on a Solaris 10 global zone to access the system for problems before migrating that system to a Solaris 10 branded zone.

Used to access a Solaris 10 global zone for problems before migrating that zone to a Solaris 11 global zone

Used to create zonecfg template for a Solaris 10 global zone that that will be migrated to a solaris10 branded zone.

Used to migrate an Oracle Solaris 11 global zone to a non-global zone.

Used to migrate a Solaris 10 global zone to a non-global zone on the same server; the non-global zone can then be migrated to a Solaris 11 server as a Solaris10 branded zone.

Answer

C, D, E

Explanation

zonep2vchk

- check a global zone's configuration for physical to virtual migration into non-global zone

The zonep2vchk utility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone.

The p2v process involves archiving a global zone (source), and then installing a non-global zone (target) using that archive

zonep2vchk serves two functions. First, it can be used to report issues on the source which might prevent a successful p2v migration. Second, it can output a template zonecfg, which can be used to assist in configuring the non-global zone target.

zonep2vchk can be executed on a Solaris 10 or later global zone. To execute on Solaris 10, copy the zonep2vchkutility to the Solaris 10 source global zone.

When run on Solaris 10, a target release of S11 can be specified, which will check for p2v into a Solaris 10 Branded zone.

[Reference: man zonep2vchk, , ]

Questions # 33:

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

Options:

You can perform a text or LiveCD installation locally or over the network.

The text Installer does not install the GNOME desktop. The GNOME desktop package must he added after you have installed the operating system.

The LiveCD Installation cannot be used to install multiple instances of Oracle Solaris.

The LiveCD installer cannot be used if you need to preserve a specific Solaris Volume Table of Contents (VTOC) slice in your current operating system.

The LiveCD Installer is for x86 platforms only.

The GUI installer cannot be used to upgrade your operating system from Solaris 10.

If you are installing Oracle Solaris 11 on an x86-based system that will have more than one operating system installed in it, you cannot partition your disk during the installation process.

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.

Questions # 34:

Which three statements are true for the Oracle Solans 111mage Packaging System (IPS)? (Choose three.)

Options:

a local repository should be stored on a 2FS file system.

Network access to an IPS repository is provided to client systems using NFS.

Network access to an IPS repository is provided to client systems using NFS and HTTP.

The distribution constructor can get packages from a local IPS to build an installation image.

A mirror repository contains all of the metadata and content for software packages.

Clients access a mirror repository to obtain a publisher's catalog and software packages.

Answer

D, E, F

Questions # 35:

The COMSTAR framework provides support for the iSCSI protocol.

Identify three true statements describing the COMSTAR framework. (Choose three.)

Options:

One IP port can handle multiple iSCSI target devices.

The disk volume provided by the server is referred to as the LUN and can be accessed by an iSCSI initiator.

The disk volume provided by the server is referred to as the target.

The iSCSI initiator is configured on the server.

E The iSCSI initiator is configured on the client.

Answer

A, C, D

Questions # 36:

The current ZFS configuration on server is:

Question # 36

You need to backup the /data file system while the file system is active.

Select the option that creates a full backup of the /data file system and stores the backup on server in the pool named backup.

Options:

Mount -F nfs system: /backup / mnt

zfs snapshot pool/data@monday>/mnt/Monday

Mount -F nfs systemB: /backup/mnt

zfs snapshot pool1/data@Monday

zfs clone pool1/data@monday/mnt/Monday

Zfs send pool1/data@Monday | ssh system zfs recv backup/monday

Zfs snapshot pool1/data@Monday | ssh system zfs recv backup/monday

Answer

Explanation

Example (assuming there exists a snapshot ‘tank/test@1).

Full backup

Now let’s do a full initial backup from the ‘tank/test@1 snapshot:

# zfs send tank/test@1 | zfs receive tank/testback

Questions # 37:

Which three statements accurately describe the Automated Installation (Al) client? (Choose three.)

Options:

if the Al client does not match any cnteria to use a custom manifest or script, the default manifest is used.

if the A! client does not match any criteria to use a custom manifest or script, the automated installation aborts.

Any manifest or script in a service can be designated to be the default for that service.

Only the default.xml file is used as the default Al client manifest.

if a client system does not use any SC profile, then an interactive tool opens on that client at first boot after that client installation to complete the

configuration of that client.

If a client system does not use any SC profile, then the install server will use the default SC profile.

Answer

A, C, E

Questions # 38:

You need to set up a local package repository to serve 75 client systems. Multiple clients will be accessing the package repository concurrently and you need to ensure that the local repository performs very well under this heavy load, especially during package-intensive operations. Which option would ensure the best performance of the repository during package-intensive operations by multiple clients?

Options:

Set up multipathing on the package repository server to distribute the network load across multiple network interfaces.

Deploy a second instance of the package repository server to run as a read-writable mirror.

Deploy a second instance of the package repository server to run as a read-only mirror.

Deploy a second instance of the package repository server to run as a clone of the primary repository server

Deploy a package repository locally on each client.
