Which three statements describe Solaris 11 boot environments (BEs)?

A.
A full backup of your OS image is provided.

B.
Packages can be installed and uninstalled in an inactive BE.

C.
The OS can be upgraded in an active BE while the system is live without impacting production.

D.
A new BE can be created from the snapshot of an existing BE.

E.
A BE can become active without rebooting the system.

F.
An active BE can be unmounted and upgraded without impacting production.

Explanation:

E: You can use the Package Manager to manage your boot environments as follows:
/Delete old and unused boot environments in order to make the disk space available
/ Active a boot environment, so that boot environment will be the new default on reboot
D: The beadm utility enables you to create a new boot environment based on an existing
snapshot.
Note:
* You can manage the boot environments on your system either by using the beadm command or
by using the Package Manager.
* A boot environment is a bootable instance of the Oracle Solaris operating system image plus any
other application software packages installed into that image. System administrators can maintain
multiple boot environments on their systems, and each boot environment can have different
software versions installed.

Not E:

software versions installed.
* Although a snapshot is not bootable, you can create a boot environment based on that snapshot
by using the -e option in the beadm create command. Then you can use thebeadm activate
command to specify that this boot environment will become the default boot environment on the
next reboot.
