Correct 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.

Correct Answer: DE

Explanation: The framework enables providers of cryptographic services to have their services used by many consumers in the Oracle Solaris operating system. Another name for providers is plugins. The framework allows three types of plugins:

*

User-level plugins - Shared objects that provide services by using PKCS #11 libraries, such as pkcs11_softtoken.so.1.

*

Kernel-level plugins - Kernel modules that provide implementations of cryptographic algorithms in software, such as AES.

Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware.

*

Hardware plugins - Device drivers and their associated hardware accelerators. The Niagara chips, the ncp and n2cp device drivers, are one example. A hardware accelerator offloads expensive cryptographic functions from the operating system. The Sun Crypto Accelerator 6000 board is one example.

Correct Answer: D

Explanation: Searching for Packages

Use the pkg search command to search for packages whose data matches the specified pattern.

Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search command returns the names of packages that match the query.

pkg search search [-HIaflpr] [-o attribute ...] [-s repo_uri] query Search for matches to the query, and display the results. Which tokens are indexed are action-dependent, but may include content hashes and pathnames.

Note: pkg is the retrieval client for the image packaging system. With a valid configuration, pkg can be invoked to create locations for packages to be installed, called 'images', and install packages into those images. Packages are published by publishers, who may make their packages available at one or more repositories. pkg, then, retrieves packages from a publisher's repository and installs them into an image.

Correct Answer: BC

B: Binary Signatures for Third-Party Software The elfsign command provides a means to sign providers to be used with the Oracle Solaris Cryptographic Framework. Typically, this command is run by the developer of a provider.

The elfsign command has subcommands to request a certificate from Sun and to sign binaries. Another subcommand verifies the signature. Unsigned binaries cannot be used by the Oracle Solaris Cryptographic Framework. To sign one or more providers requires the certificate from Sun and the private key that was used to request the certificate.

C: Export law in the United States requires that the use of open cryptographic interfaces be restricted. The Oracle Solaris Cryptographic Framework satisfies the current law by requiring that kernel cryptographic providers and PKCS #11 cryptographic providers be signed.

Correct Answer: DE

Explanation: The ipmpstat command concisely displays information about the IPMP subsystem. It supports

five different output modes, each of which provides a different view of the IPMP subsystem (address,

group, interface, probe, and target), described below.

-i

Display IP interface information ("interface" output mode).

Interface Mode

Interface mode displays the state of all IP interfaces that are tracked by in.mpathd on the system. The

following output field is one of the supported:

FLAGS

Assorted information about the IP interface:

i

(D)

Unusable due to being INACTIVE.

s

Marked STANDBY.

m

(E)

Nominated to send/receive IPv4 multicast for its IPMP group.

b

Nominated to send/receive IPv4 broadcast for its IPMP group.

M

Nominated to send/receive IPv6 multicast for its IPMP group.

d

Unusable due to being down.

h

Unusable due to being brought OFFLINE by in.mpathd because of a duplicate hardware address.

Correct Answer: ADE

Explanation: A: Each client uses one and only one AI manifest to complete its installation. The AI manifest is selected for a client according to the following algorithm:

* If no custom AI manifests are defined for this install service, the default AI manifest is used. The default AI manifest is not associated with any client criteria

etc.

D: When you create a new install service,

install_service_image_path/auto_install/manifest/default.xml is the initial default AI manifest for that install

service.

E: Each client can use any number of system configuration profiles. If a client system does not use any

configuration profile, then an interactive tool opens on that client at first boot after that client installation to

complete the configuration of that client.
