C: /etc/security/exec_attr is a local database that specifies

the execution attributes associated with profiles. The

exec_attr file can be used with other sources for execution

profiles, including the exec_attr NIS map and NIS+ table.

A profile is a logical grouping of authorizations and com-

mands that is interpreted by a profile shell to form a

secure execution environment.

Incorrect answers:

A: etc/security/prof_attr is a local source for execution profile names, descriptions, and other attributes of execution profiles. The prof_attr file can be used with other profile sources, including the prof_attr NIS map.

B: /etc/security/auth_attr is a local source for authorization names and descriptions. The auth_attr file can be used with other authorization sources, including the auth_attr NIS map and NIS+ table.

An authorization is a right assigned to users that is checked by certain privileged programs to determine whether users can execute restricted functionality.

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.

ZFS Deduplication Property

Solaris Express Community Edition, build 129: In this Solaris release, you can use the deduplication property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored and common components are shared between files.

You can enable this property as follows:

# zfs set dedup=on tank/home

dlstat show-aggr [-r | -t] [-i interval] [-p] [ -o field[,...]] [-u R|K|M|G|T|P] [link]

Display per-port statistics for an aggregation.

Incorrect answers:

dlstat show-link [-r [-F] | -t] [-i interval] [-a] [-p] [ -o field[,...]] [-u R|K|M|G|T|P] [link]

Display statistics for a link.

B: Configure the AI install server to use a static IP address and default route.

D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server for use with AI. The DHCP server must be able to provide DNS information to the systems to be installed.

E: An automated installation of a client over the network consists of the following high-level steps:

1. The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server.

2. The install server provides a boot image to the client.

3. Characteristics of the client determine which installation instructions and which system configuration instructions are used to install the client.

4. The Oracle Solaris 11 OS is installed on the client, pulling packages from the package repository specified by the installation instructions in the AI install service.

G: Install the AI tool set.

Use theinstalladm create-servicecommand to create an AI install service. Give the service a meaningful name, and specify the path where you want the service created. Specify the source of the network boot image (net image) package or ISO file.

installadm create-service [-n svcname]

[-s FMRI_or_ISO] [-d imagepath]

-dimagepath

Theimagepathis the location of the new install service. Theinstall-image/solaris-auto-installpackage is installed to this location, or the specified ISO file is expanded at this location.
