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.
You have completed configuring a zone named dbzone on your Solaris 11 server. The configuration is as following:
The global zone displays the following network information:
The zone has never been booted. Which three options correctly describe this zone?
C: Immutable Zones provide read-only file system profiles for solaris non-global zones.
Note that ip-type: exclusive:
Starting with OpenSolaris build 37 and Oracle Solaris 10 8/07, a default zone can be configured as an 'exclusive-IP zone' which gives it exclusive access to the NIC(s) that the zone has been assigned. Applications in such a zone can communicate directly with the NIC(s) available to the zone.
Note on zones:
After installing Oracle Solaris on a system, but before creating any zones, all processes run in the global zone. After you create a zone, it has processes that are associated with that zone and no other zone. Any process created by a process in a non-global zone is also associated with that non-global zone.
Any zone which is not the global zone is called a non-global zone. Most people call non-global zones simply 'zones.' Some people call them 'local zones' but this is discouraged.
The default native zone file system model on Oracle Solaris 10 is called 'sparse-root.' This model emphasizes efficiency and security at the cost of some configuration flexibility. Sparse-root zones optimize physical memory and disk space usage by sharing some directories, like /usr and /lib. Sparse-root zones have their own private file areas for directories like /etc and /var. Whole-root zones increase configuration flexibility but increase resource usage. They do not use shared file systems for /usr, /lib, and a few others.
There is no supported way to convert an existing sparse-root zone to a whole-root zone. Creating a new zone is required.
You are logged in to a Solaris 11 system as user jack. You issue the following sequence of commands:
Identify two correct statements.
Oracle Solaris provides predefined rights profiles. These profiles, listed in the /etc/security/prof_attr, can be assigned by the root role to any account. The root role is assigned all privileges and all authorizations, so can perform all tasks, just as root can when root is a user.
To perform administrative functions, you open a terminal and switch the user to root. In that terminal, you can then perform all administrative functions.
$ su - root
Password: Type root password
#
When you exit the shell, root capabilities are no longer in effect.
You are executing this command in the default shell:
sleep 5000 &
The system displays a number. This value is______.
If a command is terminated by the control operator '&', the shell executes the command asynchronously in a subshell. This is known as executing the command in the background. The shell does not wait for the command to finish, and the return status is 0 (true).
To help with your troubleshooting, you need to determine the version of the OBP. Which two commands will provide you with this information?
B: banner
Displays power-on banner.
The PROM displays the system banner. The following example shows a SPARCstation 2 banner. The banner for your SPARC system may be different.
SPARCstation 2, Type 4 Keyboard
ROM Rev. 2.0, 16MB memory installed, Serial # 289
Ethernet address 8:0:20:d:e2:7b, Host ID: 55000121
C: .version
Displays version and date of the boot PROM.
Note: OBP-OpenBootProm is a firmware which is placed on the sun machine's prom chip.
It is a os independent user interface to deal with the sun machine's hardware components.
The user interface provides one or more commands to display system information.
