NEW QUESTION 3
You need to make sure that all of the software packages on your server are up to date. Without installing any updates, which two commands would display .my software updates that are available in the default Oracle repository?

• A. pkg list -u
• B. pkg verify –u ‘*’
• C. pkg search –u
• D. pkg info –r ‘*’
• E. pkg install –nv
• F. pkg update –nv ‘*’

Answer: AD

Explanation:
A: the pgk list command display a list of packages in the current image, including state and other information. By default, package variants for a different architecture or zone type are excluded.
D: pkginfo displays information about software packages that are installed on the system (with the first synopsis, with -l) or that reside on a particular device or directory (with the second synopsis, with -r).
Without options, pkginfo lists the primary category, package instance, and the names of all completely installed and partially installed packages. It displays one line for each package selected.
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 have a ZFS file system named /dbase/oral and you want to guarantee that 10 GB of storage space is available to that dataset for all data, snapshots, and clones.
Which option would you choose?

• A. zfs set refreservation=10g dbase/oral
• B. zfs set quota=10g dbase/oral
• C. zfs set refquota=10g dbase/oral
• D. zfs set reservation=10g dbase/oral

Answer: D

Explanation:
A ZFS reservation is an allocation of disk space from the pool that is guaranteed to be available to a dataset. As such, you cannot reserve disk space for a dataset if that space is not currently available in the pool. The total amount of all outstanding, unconsumed reservations cannot exceed the amount of unused disk space in the pool. ZFS reservations can be set and displayed by using the zfs set and zfs get commands. For example:
# zfs set reservation=5G tank/home/bill
# zfs get reservation tank/home/bill NAME PROPERTY VALUE SOURCE
tank/home/bill reservation 5G local

NEW QUESTION 7
zone1 is a non-global zone that has been configured and installed.
zone1 was taken down for maintenance, and the following command was run: zoneadm -z zone1 mark incomplete
The following information is displayed when listing the zones on your system:

Which task needs to be performed before you can boot zone1?

• A. The zone needs to be installed.
• B. The zone needs to be brought to the ready state.
• C. The zone needs to be uninstalled and reinstalled.
• D. The zone needs to be brought to the complete state.

Answer: C

Explanation:
If administrative changes on the system have rendered a zone unusable or inconsistent, it is possible to change the state of an installed zone to incomplete.
Marking a zone incomplete is irreversible. The only action that can be taken on a zone marked incomplete is to uninstall the zone and return it to the configured state.

NEW QUESTION 8
Choose three options that describe the features associated with a Live Media installation.

• A. does not allow the root user to log in to the system directly from the console (or any terminal)
• B. provides a "hands free" installation
• C. installs the desktop based packages
• D. can be used to install only x86 platforms
• E. installs the server-based set of packages only
• F. allows both automatic and manual configuration of the network
• G. installs both the server-based and desktop-based package

Answer: BCD

Explanation:
The graphical installer is officially known as the "Live Media." This means that Oracle Solaris can be booted into RAM, causing zero impact on your existing operating system. After it is loaded, you are free to experiment with Oracle Solaris to determine whether it is something you would like to install to your system.
You can download Oracle Solaris 11 Live Media for x86, which is an approximately 800 MB image file, and use a DVD burner to create the disk, or you can use the ISO image directly in a virtual machine or through the Oracle Integrated Lights Out Manager (ILOM) Remote Console.
The Live Media is not intended for long-term use. For example, any changes that you make
to the system are lost when the system is shut down. Therefore, the next logical step is to install Oracle Solaris on the system, which the Live Media makes easy by placing an Install Oracle Solaris icon right on the desktop. But before we head down that road, let's step back a bit and consider the installation options.
Note: The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11 environment without installing it on a system. The system boots off the media directly allowing administrators to start the installer should they choose to install it to a system.

NEW QUESTION 9
Select the two statements that correctly describe the operation of NWAM.

• A. If a location is explicitly enabled, it remains active until explicitly changed.
• B. Wireless security keys can be configured by using the nwammgr command.
• C. NWAM stores profile information in /etc/ipadm/ipadm.conf and /etc/dladm/datalink.conf.
• D. Multiple locations may be automatically activated in systems with multiple network interface cards.
• E. Interface NCU Properties "float" and are automatically attached to the highest priority Link NCU Property.
• F. If the DefaultFixed NCP is enabled, persistent configuration, stored in /etc/ipadm.conf and /etc/dladm/datalink.conf is used.

Answer: AD

Explanation:
A: Conditional and system locations can be manually activated, which means that the location remains active until explicitly disabled.
D: A location comprises certain elements of a network configuration, for example a name service and firewall settings, that are applied together, when required. You can create multiple locations for various uses. For example, one location can be used when you are connected at the office by using the company intranet. Another location can be used at home when you are connected to the public Internet by using a wireless access point. Locations can be activated manually or automatically, according to environmental conditions, such as the IP address that is obtained by a network connection.

The core dump configuration for your system is:

A user is running a process in the global zone and the process crashes. The process information is:
User1 2663 2618 0 17:46:42 pts/2 0:00 /usr/bin/bash
The server host name is: zeus
What will the per-process core file be named?

• A. core.bash.2663.global
• B. core.bash.2663.zeus
• C. /var/core/core.bash.2663
• D. /var/core/core.bash.2663.global

Answer: C

Explanation:
Note the first line:
global core file pattern: /globalcore/core.%f.%p
The program name is bash The runtime process ID is 2663
Note: By default, the global core dump is disabled. You need to use the coreadm command with the -e global option to enable it. The -g option causes the command to append the program name(%f) and the runtime process ID (%p) to the core file name.
