Questions # 22:

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.

Questions # 23:

You upgraded your server to Oracle bolans 11 and you imported a zpool(pooll) that was created in bolaris 10. You need to create an encrypted ZFS file system in pooll, but first you need to make sure that your server supports ZFS encryption.

Which four statements are true for support of ZFS encryption?

Options:

The encrypted file system must have been created in Oracle Solaris 11. To encrypt a ZFS file system from a previous version of Solaris, upgrade

the zpool and create a new encrypted ZFS file system in that zpool Finally, move or copy the data from the existing ZFS file system into the new encrypted ZFS file system.

if you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30, minimum.

ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.

ZFS encryption requires that the ZFS Dataset Encryption package be installed.

E If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 21, minimum. D f Encryption is supported at the pool or dataset (file system) level

Encryption is supported at the pool level only and every file system in the pool will be encrypted.

You cannot create an encrypted file system in a zpool that was created prior to Oracle Solaris 11.

Create a new zpool in Solaris 11, create an encrypted ZFS file system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.

Questions # 24:

You create a flash archive of the Solaris 10 global zone on the server named sysA and you name the archive s10-system.flar.

You upgrade the operating system on sysA from Solaris 10 to Oracle Solaris 11.

On sysA, you want to create a Solaris 10 non-global zone and import the flash archive into that zone The flash archive is available on sysA via NFS through the mountpoint;/net/backup_server/backup_server.

Which two options do you choose to create the Solaris 10 zone capable of supporting the Solaris 10 flash archive? (Choose two.)

Options:

zonecfg -z s 10-zone create-tSYSsolarislO

zonecfg -z s 10-zone

create setbrand=solaris10

zonecfg -z solarisl 0 -t SYSsolarislO

zonecfg -z s10-zone install -f/net/backup_setver/s1O-system.flar

Question # 25

The file came from your Automated Installer (Al) Install server.

The file is_______.

Options:

an Al SC profile for non-global zones

the default Al config file for non-global zones

the default Al manifest for non-global zones

a custom Al manifest

Questions # 26:

The rctladm command reports the following:

# rctladm |grep task.max.lwps task.max-lwps syslog=notice [ count 1

Which of the following correctly describes the system configuration?

Options:

A message will be logged with syslogd when the number of notice messages generated by the resource control threshold meets or exceeds the value specified with [count]

A message will be logged with sysloqd when the number of violations generated by the resource control threshold meets or exceeds the value specified with [count].

The global resource control monitoring for the task.max-lwps resource control has been enabled and syslog messaging for that resource control has been set to notice. However, because the [count] value has not been specified, there is no threshold set for the resource to monitor. The configuration to monitor the task.max-lwps resource control is incomplete.

The global resource control monitoring for the task.max-lwps resource control has been enabled, syslog messaging for that resource control has been set to notice.

Questions # 27:

I he Automated Installer is used, rather than JumpStart, to install the Oracle Solans 11 operating System. Identify the two correctly matching pairs of equivalent functionality. {Choose two.)

Options:

AJ: manifest files

JumpStart: begin script

Al:installadmcreate-client

JumpStart: setup_install_sen/er

Al SMF system configuration profile files JumpStart: profile files

Al: SMF system configuration profile files JumpStart: finish scripts and sysidcfg files

Questions # 28:

Review the output from a ZFS file system:

NAMEPROPERTYVALUESOURCE

pool1/encryptencryptionaes-256-ccmlocal pool1/encryptkeysourceraw,file///mykeylocal

You need to recreate the pooM/encrypt file system exactly as it is listed above Which two commands can you use to recreate the pooM/encrypt file system?

(Choose two.)

Options:

pktool genkey keystone=file outkey=/mykey keytype=aes keylen=256

genkey pktool keystore=file outkey=/mykey keytype=aes keylen=256

zfs create -o encryption=aes-256-ccm -o keysource=raw,file://mykey pooll/encrypt

zfs create -o encryption=aes-256-ccm -o keysource=raw,file:///mykey pooM/encrypt

zfs create -o encryption=aes-256-ccm -o keysource=raw,file:///mykey source=local pooll/encrypt

Questions # 29:

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

Options:

There are boot environments for zones.

Administrators can delegate common administration tasks by using RBAC.

Oracle Solaris 11 supports Solaris 8, 9, and 10 branded zones.

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.

It is possible to change the host ID of a zone.

Questions # 30:

The following information is displayed during the migration of a ZFS file system:

Question # 30

Which answer correctly describes the status of the migration?

Options:

The new file system is named pool1/data1, the shadowstat command was used to generate the output, and the migration is still in progress.

The shadowed file system is named pool1/data1, the shadowstat command was used to generate the output, and the migration is still in progress

25.5 GB of data has been transferred so far. 409 MB of data remains to be transferred

The shadowed file system is named pool1/data1. the shadowstat command was used to generate the output, and the migration is still in progress with 409 MB remaining to be transferred to the target filesystem.

The new file system is named pool1/data1, the shadow command was used to generate the output, and the migration is still in progress.

The shadowed file system is named pool1/data1, the shadow command was used to generate the output, and the migration is still in progress.

27.3 GB is the exact size of the data that is yet to be transferred from the shadowed file system.
