* (Not A, B, C): interval (here 10 seconds): Specifies the length in seconds to pause between each interval report.

* duration (here 24 h)

* -R report[,report] (here high)

Print a summary report.

high Print a summary report detailing the highest usage of each resource and zone during any interval of thezonestatutility invocation.

Note: The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as a percentage of system resources and the zone's configured limits.

The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval.

The default output is a summary of cpu, physical, and virtual memory utilization. The -r option can be used to choose detailed output for specific resources.

Oracle Solaris 10 branded zones -- Oracle Solaris 10 Zones provide an Oracle Solaris 10 environment on Oracle Solaris 11. You can migrate an Oracle Solaris 10 system or zone to a solaris10 zone on an Oracle Solaris 11 system in the following ways:

* Create a zone archive and use the archive to create an s10zone on the Oracle Solaris 11 system.

This option applies in the current scenario.

Example of command to Install the Oracle Solaris 10 non-global zone.

s11sysB# zoneadm -z s10zone install -u -a /pond/s10archive/s10.flar

* Detach the zone from the Oracle Solaris 10 system and attach the zone on the Oracle Solaris 11 zone. The zone is halted and detached from its current host. The zonepath is moved to the target host, where it is attached.

Note:

install [-x nodataset] [brand-specific options]

A subcommand of the zoneadm.

Install the specified zone on the system. This subcommand automatically attempts to verify first. It refuses to install if the verify step fails.

-uuuid-match

Unique identifier for a zone, as assigned bylibuuid(3LIB). If this option is present and the argument is a non-empty string, then the zone matching the UUID is selected instead of the one named by the-zoption, if such a zone is present.

Incorrect answers:

B: Theattachsubcommand takes a zone that has been detached from one system and attaches the zone onto a new system. Therefore, it is advised (though not required) that thedetachsubcommand should be run before the ''attach'' takes place. Once you have the new zone in the configured state, use theattachsubcommand to set up the zone root instead of installing the zone as a new zone.

shadowd is a daemon that provides background worker threads to migrate data for a shadow migration. A shadow migration gradually moves data from a source file system into a new ''shadow'' file system. Users can access and change their data within the shadow file system while migration is occurring.

The shadowd service is managed by the service management facility, smf(5). Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.

The svccfg(1M) command can be used to manage the following parameter related to shadowd:

config_params/shadow_threads

Note: Oracle Solaris 11: In this release, you can migrate data from an old file system to a new file system while simultaneously allowing access and modification of the new file system during the migration process.

Setting the shadow property on a new ZFS file system triggers the migration of the older data. The shadow property can be set to migrate data from the local system or a remote system with either of the following values:

file:///path

nfs://host:path

A: You can use the distribution constructor to create the following types of Oracle Solaris images:

* (A) x86 or SPARC ISO Image for Automated Installations

* Oracle Solaris x86 live CD image

* x86 or SPARC Oracle Solaris text installer image

* x86 Oracle Solaris Virtual Machine

Note: You can use the distribution constructor to build custom Oracle Solaris images. Then, you can use the images to install the Oracle Solaris software on individual systems or multiple systems. You can, also, use the distribution constructor to create Virtual Machine (VM) images that run the Oracle Solaris operating system.

D: Checkpointing Options

You can use the options provided in the distro_const command to stop and restart the build process at various stages in the image-generation process, in order to check and debug the image that is being built. This process of stopping and restarting during the build process is called checkpointing.

Incorrect answers:

B: Optionally, a USB image can be created, based on a generated x86 ISO image.
