Which three options accurately describe Oracle Solaris 11 zones?
A.
can be NFS servers
B.
are whole root type only
C.
cannot have their own time zone setting
D.
can execute z�s and zpool commands (from a non-global zone)
E.
are virtualized operating system environments, each with its own dedicated OS and kernel
F.
are virtualized operating system environments, created with a single instance of the OS shared
kernel
Explanation:
A: Zones can use Oracle Solaris 11 products and features such as the following:
Oracle Solaris ZFS encryption
Network virtualization and QoS
CIFS and NFS
C: Non-global zones cannot modify the system clock by default, but each zone can have a
separate time zone setting.
F (not E): The Oracle Solaris Zones partitioning technology is used to virtualize operating system
services and provide an isolated and secure environment for running applications. A zone is a
virtualized operating system environment created within a single instance of the Oracle Solaris
operating system.

Oracle Solaris 11 Zone Features:
Oracle Solaris 10 branded zones
Oracle Solaris 11 installation support, such as AI
Oracle Solaris Zones are whole-root type only
Exclusive IP zones by default
Network virtualization for zones
NFS server support in non-global zones

Solaris 11 zones are whole-root type only. so I believe A.B.F are correct
Confused. Would say 4 answers are correct.
A B D F
A B D F
A, B and F are correct, but D also could be correct answer.
Although changes are only supported with dataset in a non-global zone, the operations of listing pools and datasets are possible in the non-global zone.
http://docs.oracle.com/cd/E23824_01/html/821-1448/gayov.html#gbbre
you can delegate ZFS to a non-global zone – D is valid answer
Yes, but you can execute ZFS an ZPOOL commands AFTER the theyre delegated.
“Using ZFS Storage Pools Within a Zone
ZFS storage pools cannot be created or modified within a zone. The delegated administration model centralizes control of physical storage devices within the global zone and control of virtual storage to non-global zones.”
“AFTER (!) a dataset is delegated to a zone, the zone administrator can control specific dataset properties.”
http://docs.oracle.com/cd/E23824_01/html/821-1448/gayov.html#gbbre
The Question is not very straight….
i think i have the answer –
the question is to zfs _and_ zpool-commands.
…yes, you can use ZFS-Commands after delegation in a zone
…no, i think you are not able to use ZPOOL-Commands in a zone – to create a tank is stuff of the global zone admin.
is anybody able to test that?
A, B and F for sure
Answer is ADF.
B is wrong.
As you can see, the statement “Solaris 11 Zones are whole-root zones” is only true using the narrowest definition of whole-root zones: those zones which have their own copy of Solaris packaging content. But there are other valuable characteristics of sparse-root zones that are still available in Solaris 11 Zones. Also, some Solaris 11 Zones do not have some characteristics of whole-root zones

I think A,B,D
its A,B,F
ADF
Correct: A

New to Oracle Solaris 11, NFS servers are now supported in a non-global zone.
Correct: D
In addition to the default dataset described in File Systems Mounted in Zones, you can add a ZFS dataset to a non-global zone by using the zonecfg command with the add dataset resource. The dataset is be visible and mounted in the non-global zone, and also visible in the global zone. The zone administrator can create and destroy file systems within that dataset, and modify the properties of the dataset.
