QUESTION 1

Which two statements are correct?

B. The pattern [fF]*a? will expand to [fF] *a?.
C. The pattern [gfe] * will expand to file filea fileb filec.
D. The pattern [g-e] * will expand to file filea fileb filec.
E. The pattern [fF] [a-zA-z] i*e will expand to file.
Answer: A,C

QUESTION 2
What determines which bits in an IP address represent the subnet, and which represent the host?
A. Subnet
B. unicast
C. netmask
D. multicast
E. broadcast
Answer: C
Explanation:
A subnetwork, or subnet, is a logically visible subdivision of an IP network. The practice of
dividing a network into two or more networks is called subnetting.
The routing prefix of an address is written in a form identical to that of the address itself. This is called the network mask,
or netmask, of the address. For example, a specification of the most-significant 18 bits of an IPv4 address,
11111111.11111111.11000000.00000000, is written as 255.255.192.0.
QUESTION 3
How are operating system updates distributed in the Oracle Solaris 11 environment?
A. Updates are only available to customers with an active support contract. The updates are distributed through the My
Oracle Support web portal and installed in a central location. All software packages are then updated manually from the command line using the smpatch command.
B. Patches are download from http: //support.oracle.com either automatically or manually. All software packages are then updated manually from the command line using the smpatch or patchadd commands.
C. Software updates are published as packages to a repository. All software packages are then updated manually from the command line using the pkg command.
D. Software updates, published as packages to an OS image. All software packages are then updated manually from the command line using the pkg command.
Answer: C
Explanation:
* Updating all of the packages on your installed system – To update all of the packages on your system that have available updates, use the pkg update command, as follows:
# pkg update
Running this command updates packages that you might not otherwise consider updating, for example, kernel components and other low-level system packages.
* Adding or updating individual packages – To add individual software packages, use the pkg install command. Any dependent packages are also updated at the same time.
* install package updates that deliver fixes– A pkg update operation might include bug
fixes, so the operation is similar to applying a specific patch or patches in previous Oracle Solaris releases.
Note: The IPS interfaces first check for updates for currently installed packages before retrieving them via the network.
By default, interfaces check repository catalogs in the following locations:
* The default installation repository at pkg.oracle.com/solaris/release.
* The support repository in My Oracle Support. This repository is restricted to users with Oracle Solaris 11 Express
support contracts, and it contains packages with the latest bug fixes. For this reason, a support contract must be
purchased for production deployments.
QUESTION 4
Which two accurately identify features of a Solaris 10 branded zone?
A. executes in a Solaris 10 global zone
B. is created by importing a Solaris 10 flash archive
C. enables Linux binary applications to run unmodified
D. provides a complete runtime environment for Solaris 9 applications
E. allows a Solaris 10 global zone to be migrated into a Solaris 10 non-global zone on a Solaris 11 system
Answer: B,E
Explanation:
B: It can be created by importing a Solaris 10 flash archive.
You can use the Oracle Solaris Flash archiving tools to create an image of an installed system that can be migrated into a zone.
The system can be fully configured with all of the software that will be run in the zone before the image is created. This
image is then used by the installer when the zone is installed.
Note: You can use alternate methods for creating the archive. The installer can accept the
following archive formats:
* cpio archives
* gzip compressed cpio archives
* bzip2 compressed cpio archives
* pax archives created with the -x xustar (XUSTAR) format Ä ufsdump level zero (full) backups
Note:
Branded zones that run an environment different that the OS release on the system
* The lx branded zone introduced in the Solaris 10 8/07 release provides a Linux environment for your applications and
runs on x86 and x64 machines on the Oracle Solaris 10 OS.

* The solaris8 and solaris9 branded zones enable you to migrate an Oracle Solaris 8 or Oracle Solaris 9 system to an
Oracle Solaris 8 or Oracle Solaris 9 Container on a host running the Oracle Solaris 10 8/07 Operating System or later
Oracle Solaris 10 release.
* The Oracle Solaris 10 Container brand is available in OpenSolaris build 127. These branded zones host Oracle Solaris
10 user environments.
Note: One of the powerful features of Solaris 11 is the ability to run a Solaris 10 environment in a zone. Solaris 10
allows you to run Solaris 8 and 9 environments in zones, but only on SPARC.
QUESTION 5

What command would you use to configure where the core files are saved?
A. savecore
B. dumpadm
C. svcadm
D. proc
E. coreadm
Answer: E
Explanation:
The coreadm command is used to specify the name and location of core files produced by abnormally-terminating processes.
