Upgrade to Oracle Solaris 11 System Administrator Questions and Answers

Question 1

You need to migrate a UFS file system named /production_ufs to a ZFS file system named /production_ufs. The /production_ufs file system cannot be taken down or be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.

Which method allows you to meet both requirements?

1. Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.

2. When the copy is complete, /production_zfs will contain an up-to date copy of /production_ufs

Options:

Create a snapshot of the UFS file system.

Create the new ZFS file system.

Use cpio to copy data from the snapshot to the new ZFS file system.

Create a new Boot Environment.

Create the ZFS file system.

Use lucreate -m to copy data from the Current UFS file system to the new ZFS file system.

Mirror the existing UFS file system by using SVM.

After both submissions are in sync, migrate one of the submissions to a ZFS file System by using Live Upgrade.

Create the new ZFS file system by using zfs create import to import data from the existing UFS file system into the new ZFS file system

Create the new zfs file system by using the zfs create -o shadow.

Question 10

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.

Question 11

Before booting testzone. a non-global zone, you want to connect to the zone s console so that you can watch the boot process. Choose the command used to connect to testzone's console.

Options:

zoneadm -C testzone

zoneadm -console testzone

Question 12

The core dump configuration in your non global zone is

A user is running a process in a non-global zone (testzone) and the process crashes. The process information is:

user126632618017:46:42pts/20:00/usr/bin/bash

When the user's process crashes in testzone, a non-global zone, where will the core dump be saved?

Options:

The file will be stored in the non-global zone's directory: /var/core/pprocess/core.hash.2663.

The file will be saved in the global zone's directory: /var/core/core.bash.2663.

A core file cannot be generated in a non-global zone because it shares the kernel with the global zone.

The file will be stored in the global zone's directory: /var/core/pprocess/core.bash.2663.

The file will be saved in non-global zone’s directory: /var/core/core.bash.2663

To accomplish this, you will create__________.

Options:

An ether stub

A virtual router

A virtual switch

A virtual bridge.

A virtual network interface

Nothing because a virtual switch is automatically created then the virtual network interfaces are created.

Question 14

You created a new zpool. Now you need to migrate the existing ZFS file system from pool1/prod to pool2/prod.

You have these requirements:

1. Users must have access to the data during the migration, so you cannot shutdown the file system while the migration takes place.

2. Because you want to copy the data as quickly as possible, you need to increase the server resources devoted to the ZFS migration.

Which method would you use to modify the ZFS shadow migration daemon defaults to increase the concurrency and overall speed of migration?

Options:

Svccfg - s filesystem/shadowd:default

setprop config_params/shadow_threads=integer: 16

end

svcadm refresh filesystem/shadowd: default

Specify the -b option with the zfs create command and increase the value of

Use the -o -volblocksize=option with the zfs create command and increase the value of the default .

Svccfg -s filesystem/zfs: default

setprop config_params/shadow_threads = integer: 16

end

svcadm refresh filesystem/zfs:default

Question 15

New features wore added to ZFS in Oracle Solaris11. Your justification to upgrade from Solaris10 to oracle Solaris11 is that it will be possible to take advantage of the enhancements that were made to ZFS.

Identify the three ZFS functions and features that are included in Oracle Solaris 11, but not in Solaris 10.

Options:

Encrypted ZFS datasets

Ability for ZFS to detect and remove redundant data from the tile system

Shadow Data Migration

Ability to split a mirrored ZFS storage pool

Ability to use ZFS on the boot drive and boot to a ZFS root file system.

elimination of the swap file system when using ZFS on the root disk

Question 16

You are going to create live zones on you server. Disk space is critical on this server so you need to reduce the amount of disk space required for these zones. Much of the data required for each of these zones is identical, so you want to eliminate the duplicate copies of data and store only data that is unique to each zone.

Which two options provide a solution for eliminating the duplicate copies of data that is common between all of these zones?

Options:

Create the zones by using sparse root zones.

Set the dedup property to on and the dedupratio to at least 1.5 for the zpool.

Create a separate ZFS file system for each zone in the zpool.

Put all of the zones in the same ZFS file system and set the dedupratio property for the ZFS file system to at least 1.5.

Put all of the zones in the same ZFS file system and set the dedup property for the file system to on.

Put each zone in a separate ZFS file system within the same zpool.

Set the dedup property to on for each ZFS file system.

Question 17

Solaris 11 includes a redesigned software packaging model: the Image Packaging system.

Which three describe advantages of the Image Packaging System over the previous Solaris 10 SVR4 packaging model?

Options:

Eliminates patching of the software package

Makes the patching process more efficient with less downtime

Eliminates OS version upgrade

Allows for the installation of the OS without a local DVD or installation server

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?

Options:

zpool destroy pool2

zpool attach pool1 c3t4d0 ct3t5d0

zpool destroy pool2

zpool attach pool1 c3t2d0 c3t2d0 c3t4d0 c3t5d

Question 19

View the Exhibit and review the zpool and ZFS configuration information from your system.

Identify the correct procedure for breaking the /prod_data mirror, removing c4t0d0 and c4t2d0, and making the data on c4t0d0and c4t2d0 accessible under the dev_data mount point.

Options:

zpool split pool1 pool2 c4t0d0 c4t2d0

zpool import pool2

zfs set mountpoint = /dev_data pool2/prod_data

zpool detach pool1 pool2
