NEW QUESTION 1
You are attempting to edit your crontab file in the bash shell. Instead of getting your usual vi interface, you are presented with an unfamiliar interface. In order to have your editor of choice-vi- what command must you type after exiting the unfamiliar editor?

• A. EDITOR=vi
• B. crontab=vi
• C. crontab – e vi
• D. env

Answer: A

Explanation: Set the EDITOR variable to vi.
Commands like `crontab -e` will use ed per default. If you'd like to use some better editor (like vi) you can use the environment variable EDITOR:
# EDITOR=vi; crontab –e will open the users crontab in vi. Of course you can set this variable permanently.
Incorrect answers
C: -e Edits a copy of the current user's crontab file, or creates an empty file to edit if crontab does not exist. When editing is complete, the file is installed as the user's crontab file. If a username is given, the specified user's crontab file is edited, rather than the current user's crontab file; this can only be done by a user with the solaris.jobs.admin authorization. The environment variable EDITOR determines which editor is invoked with the -e option. The default editor is ed(1). All crontab jobs should be submitted using crontab. Do not add jobs by just editing the crontab file, because cron is not aware of changes made this way.

NEW QUESTION 2
Identify three options that describe the new Oracle Solaris 11 zone features.

• A. There are boot environments for zones.
• B. Administrators can delegate common administration tasks by using RBAC.
• C. Oracle Solaris 11 supports Solaris 8, 9, and 10 branded zones.
• D. You can migrate a physical Solaris 10 system and its non-global zones to a solaris10 branded zone running on an Oracle Solaris 11 system.
• E. It is possible to change the host ID of a zone.

Answer: ABD

Explanation: A: The beadm utility includes support for creating and administering non-global zone boot environments.
Note: 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.
B: Role-based access control (RBAC) is a security feature for controlling user access to tasks that would normally be restricted to the root role. By applying security attributes to processes and to users, RBAC can divide up superuser capabilities among several administrators.

NEW QUESTION 3
View the following information for a software package:

Which command would you use to display this information for a software package that is not currently installed on your system?

• A. pkg list gzip
• B. pkg info -r gzip
• C. pkg search –1 gzip
• D. pkg verify –v gzip
• E. pkg contents gzip

Answer: B

Explanation: By default, the pkg info command only lists information about installed packages on the system; however, we can use a similar command to look up information about uninstalled packages, as shown in here:
Example:
Listing Information About an Uninstalled Package
# pkg info -r php-52 Name: web/php-52 Summary: PHP Server 5.2
Description: PHP Server 5.2 Category: Development/PHP State: Not Installed Publisher: solaris
Version: 5.2.17
Build Release: 5.11
Branch: 0.175.0.0.0.1.530

FMRI: pkg://solaris/web/php-52@5.2.17, 5.11-0.175.0.0.0.1.530:20111012T140141Z
Note: pkg info command displays information about packages in a human-readable form. Multiple FMRI patterns may be specified; with no patterns, display information on all
installed packages in the image.
With -l, use the data available from locally installed packages. This is the default.
With -r, retrieve the data from the repositories of the image's configured publishers. Note that you must specify one or more package patterns in this case.

NEW QUESTION 4
You are logged in to a Solaris 11 system as user jack. You issue the following sequence of commands:

Identify two correct statements.

• A. You have the effective privilege of the account root.
• B. Your GID is 10.
• C. Your home directory is /root.
• D. You are running the shell specified for the account root.
• E. Your UID is 1.

Answer: AB

Explanation: 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.

NEW QUESTION 5
You create a flash archive of the Solaris 10 global zone on the serves named sysA. The archive name is s10-system.flar, and it is stored on a remote server named backup_server.
On sysA, you create a Solaris 10 branded zone named s10-zone.
You want to use the flash archive, located On" /net/bactup_servers/10-system.flar, to install the Operating system in the s10-zone zone.
Which command do you choose to install the s10-system.flar archive in the Solaris 10 branded zone (s10-zone)?

• A. zoneadm -z s10 -zone install - a /net/backup_server/s10-system.flar -u
• B. zonecfg -z s10 -zone install - a /net/backup_server/s10-system.flar -u
• C. zoneadm - z s10 -zone clone - s /net/backup_server/s10-system.flar
• D. zone cfg - a s10-zone create - t SUNWsolaris10</net/backup_server/s10-system.flar
• E. zonecfg -z s10-zone install -f /net/backup/backup_server/s10-system.flar

Answer: A

Explanation: The zoneadm command is the primary tool used to install and administer non-global zones. Operations using the zoneadm command must be run from the global zone on the target system.
How to Install the solaris10 Branded Zone
A configured solaris10 branded zone is installed by using the zoneadm command with the install subcommand.
Example: global# zoneadm -z s10-zone install -a /net/machine_name/s10-system.flar –u

NEW QUESTION 6
You have been asked to do an orderly shutdown on a process with a PID of 1234, with the kill command.
Which command is best?

• A. kill -2 1234
• B. kill -15 1234
• C. kill -9 1234
• D. kill -1 1234

Answer: B

Explanation: On POSIX-compliant platforms, SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.
SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process, but unlike the SIGKILL signal, it can be caught and interpreted (or ignored) by the process. Therefore, SIGTERM is akin to asking a process to terminate nicely, allowing cleanup and closure of files. For this reason, on many Unix systems during shutdown, init issues SIGTERM to all processes that are not essential to powering off, waits a few seconds, and then issues SIGKILL to forcibly terminate any such processes that remain.

NEW QUESTION 7
Which two statements are true when updating Solaris 11 from one Support Respository Update (SRU) to another SRU by using the pkg update command?

• A. By default, the pkg update command automatically creates a backup Boot Environment whenever the kernel is affected by the update.
• B. By default, the pkg update command automatically creates a new Boot Environment whenever the kernel is affected by the update.
• C. The pkg update command can only be used to update to a newer SRU.
• D. The pkg update command can be used to update to a newer or older SRU.
• E. By default, the pkg update command always updates Solaris 11 to the first SRU that was released after the Current SRU.
• F. The pkg update command can only be performed while running in the single-user milestone.

Answer: BC

You display the IP interface information with ipmpstat -i.
Which two characteristics are indicated by characters that may be included in the FLAGS column?

• A. default route
• B. IP forwarding enabled IS
• C. allocated to global zone
• D. unusable due to being inactive
• E. nominated to send/receive IPv4 multicast for its IPMP group

Answer: DE

Explanation: FLAGS
Indicates the status of each underlying interface, which can be one or any combination of the following:
(D) d indicates that the interface is down and therefore unusable.
(E) M indicates that the interface is designated by the system to send and receive IPv6 multicast traffic for the IPMP group.
Note:
i indicates that the INACTIVE flag is set for the interface. Therefore, the interface is not used to send or receive data traffic.
s indicates that the interface is configured to be a standby interface.
m indicates that the interface is designated by the system to send and receive IPv4 multicast traffic for the IPMP group.
b indicates that the interface is designated by the system to receive broadcast traffic for the IPMP group.
h indicates that the interface shares a duplicate physical hardware address with another interface and has been taken offline. The h flag indicates that the interface is unusable.

NEW QUESTION 15
You have been tasked with creating a dedicated virtual network between two local zones within a single system. In order to isolate the network traffic from other zones on that system.
To accomplish this, you will create .

• A. An ether stub
• B. A virtual router
• C. A virtual switch
• D. A virtual bridge.
• E. A virtual network interface
• F. Nothing because a virtual switch is automatically created then the virtual network interfaces are created.

Answer: A

Explanation: Etherstubs are pseudo ethernet NICs which are managed by the system administrator. You can create VNICs over etherstubs instead of over physical links. VNICs over an etherstub become independent of the physical NICs in the system. With etherstubs, you can construct a private virtual network that is isolated both from the other virtual networks in the system and from the external network. For example, you want to create a network environment whose access is limited only to your company developers than to the network at large. Etherstubs can be used to create such an environment.
Note: Oracle Solaris 11 introduces a new and powerful network stack architecture which includes:
* Networking virtualization with virtual network interface cards (VNICs) and virtual switching (etherstubs)
* Tight integration with zones
* Network resource management - efficient and easy to manage integrated quality of service (QoS) to enforce bandwidth limit on VNICs and traffic flows

NEW QUESTION 16
View the Exhibit and review the zpool and ZFS configuration information from your system.

Identify the correct procedure for breaking the /prod_data mirror, removing c4t0d0 and c4t2d0, and making the data on c4t0d0and c4t2d0 accessible under the dev_data mount point.

• A. zpool split pool1 pool2 c4t0d0 c4t2d0zpool import pool2zfs set mountpoint = /dev_data pool2/prod_data
• B. zpool detach pool1 pool2zpool attach pool2zfs set mountpoint=/dev_data pool2/prod_data
• C. zpool split pool1/prod_data -n pool2/dev_datazfs set mountpoint = /dev_data pool2/prod_data
• D. zpool split pool1 pool2 c4t0d0 c4t2d0zpool import pool2

Answer: D

Explanation: In this Solaris release, you can use the zpool split command to split a mirrored storage pool, which detaches a disk or disks in the original mirrored pool to create another identical pool.
After the split operation, import the new pool.

NEW QUESTION 17
The default publisher on your system is:

You want to update the Oracle Solaris 11 environment on your system, but you are not able to connect this system to the Internet to access the default Oracle repository. A repository has been created on your local network and is named http://server1.example.com.
Which command would you choose to connect your system to the local repository?

• A. pkg publisher to specify the new publisher
• B. pkg set-publisher to set the stickiness on the http://server1.example.com publisher and unset stickiness for http://pkg.oracle.com/solaris/release
• C. pkg add-publisher to add the new publisher
• D. pkg set-publisher to set the origin for the publisher

Answer: D

Explanation: Solaris 11 Express makes it pretty easy to set up a local copy of the repository.
A common reason folks need access to a local repository is because their system is not connected to the Internet.
Tthe pkg set-publisher command can be used to for example add a publisher or to enable or disable a publisher.
Note: Example Adding a Publisher
Use the -g option to specify the publisher origin URI.
# pkg set-publisher -g http://pkg.example.com/release example.com Example Specifying the Preferred Publisher
Use the -P option to specify a publisher as the preferred publisher. The specified publisher moves to the top of the search order. You can specify the -P option when you add a publisher or you can modify an existing publisher.
# pkg set-publisher -P example.com Example Enabling or Disabling a Publisher
Use the -d option to disable a publisher. The preferred publisher cannot be disabled. A disabled publisher is not used in package operations such as list and install. You can modify the properties of a disabled publishers.
Use the -e option to enable a publisher.
# pkg set-publisher -d example2.com
