Question 2

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

The application development team requested an up-to-date copy of the data from the /prod_data file system. You decide to give the team one of the disk drives containing the data by breaking the mirror, removing the disk c4t1d0 and mounting c4t1 dO under a new mount point named /dev_data. Identify the correct procedure for breaking the mirror, removing c4t1d0. and making the data on that drive accessible under the /dev_data mount point

Options:

zfs destroy pooh /prod_data

zfs create pool1/prod_data c4t1d0 zfs create pool1/dev_data c4t1d0

zfssplitpool1/prod_data

zfs mount -F zfs pool1/dev_data c4t1d0

Question 3

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.

Question 4

configuration type-'zone" name-'dbzone" cfg/zonecfQ7 >

Which statement is true with regard to the zone.cfg file?

Options:

The zone.cfg file is a text file in a zonecfg export format.

The zone.cfg file is an Al manifest that specifies how the zone is to be installed.

The zone.cfg file is an XML file in a form suitable for use as a command file for the zonecfg command.

The zone.cfg file is an SC profile with keywords that are specific for configuring a zone as part of the installation process.

ft is an XML configuration file from the /etc/zone directory. It will be used as a profile for the zone. It specifies the zonename. zonepath, and other zonecfg parameters

Question 8

Question 12

You create a flash archive of the Solaris 10 global zone on the serves named sysA. The archive name is s10-system.flar, and it is stored on a remote server named backup_server.

On sysA, you create a Solaris 10 branded zone named s10-zone.

You want to use the flash archive, located On" /net/bactup_servers/10-system.flar, to install the Operating system in the s10-zone zone.

Which command do you choose to install the s10-system.flar archive in the Solaris 10 branded zone (s10-zone)?

Options:

zoneadm -z s10 -zone install - a /net/backup_server/s10-system.flar -u

zonecfg -z s10 -zone install - a /net/backup_server/s10-system.flar -u

Question 13

You upgraded your server to Oracle Solaris 11 and you imported zpool (pool1) that was created in Solaris 10. You need to create an encrypted ZFS file system in pool1, 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 Solaris11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and create a new encrypted ZFS file system into the 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.

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.

If you plan to create an encrypted file system in an existing zpool, the pool must be upgraded to ZFS version 21, minimum.

Encryption is supported at the pool or dataset (file system) level.

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

Question 14

Which four statements describe the function of the svc://system/install/server;default service? (Choose four.)

Options:

it associates an install image with a named install service.

Client systems use the service name to find the correct install image.

Every Oracle Solaris 11 system uses this service to find its IPS publisher and to locate its IPS repository.

A server can have multiple instances of the install/server service, each associated with one boot image.

This service is not present on a server by default.

This service is present on every Oracle Solaris 11 system, but it is not enabled.

A new install/server service cannot be created without DHCP.

Question 15

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

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

Options:

sys-unconfig

installadm set-criteria

sysconfig create-profile

installadm create-profile

Question 16

Identify the Automated Installer’s (AI) equivalent to jumpStart’s finish scripts and sysidcfg files.

Manifest files

SMF system configuration profile files

Installadm create - client

IPS software package repository

installadm create-service

svccfg - s application/pkg/server setprop sysidcfg

Question 17

View the exhibit to inspect the file system configuration on your server.

You department's backup policy is to perform a full backup to a remote system disk on Saturday.

On each weekday, you are to perform an incremental backup to the same remote system disk.

Each incremental backup will contain only data that has been modified since the previous Saturday backup.

The server file systems must remain available at all times and can never be taken offline.

The backup must not only provide for the recovery of the most recent version of a file, but must also allow recovery of previous versions of a file.

Following your company policy, which two describe the correct procedure to be performed on each weekday for backing up the /data file system to a remote disk named /remote/backup?

Options:

Remove the previous daily snapshot.

zfs snapshot pool1.data@daily

zfs send - i pool1/data@sat pool1/data@daily > /remote/backup/full

Remove the previous daily snapshot.

zfs snapshot pool1.data@daily

zfs send - i pool1/data#sat pool1/data@daily | zfs recv remote /backup/ ‘date ‘+%m%d%’

Remove the previous daily snapshot.

zfs snapshot pool1.data@daily

zfs send - i pool1/data@sat pool1/data@daily > /remote/backup/daily

Remove the previous daily snapshot.

zfs create - i pool1/data@sat pool1/data@daily

zfs send pool1/data@daily | zfs remote/backup

Question 18

After installing the OS, you boot the system and notice that the syslogd daemon is not accepting messages from remote systems.

Which two options should you select to modify the syslogd daemon configuration so that it accepts syslog messages from remote systems? (Choose two.)
