1z0-822 Exam Dumps : Oracle Solaris 11 Advanced System Administration

Profiles are, in many ways, similar to manifests in that they use the same XML DTD. However, instead of providing information about a service, its dependencies, and methods, a profile is used to provide customization of a service or an instance of a service. Customizations include whether an instance of a service should be enabled or disabled and any modifications to service configuration properties.

Incorrect:

Not A: Manifests (not profiles) are used to describe services and instances of a service, including any property groups and properties they might have.

svccfg

subcommand: revert [snapshot]

Reverts the administrative customizations of the currently selected instance and its service to those recorded in the named snapshot. If no argument is given, use the currently selected snapshot and deselect it on success.

Incorrect:

Not A: Rollback to as-delivered system: svccfg delcust

svccfg

subcommand: delcust [-M] [pattern]

Delete any administrative customizations for the current selection. If an argument is supplied, it is taken as a glob pattern and only property groups and properties with names that match the argument are deleted.

Not B: There is no command revetsnap

Not C: Run the command /lib/svc/bin/restore_repository, and follow its instructions to restore one of the automatic backup copies of the repository. Upon successful completion, the system or local zone will be rebooted, and the restored repository will take effect.

Not D:

Note:

* The Trusted Solaris environment provides audit classes including:

ss - Change system state

no - Invalid class

lo - Login or logout

* always-audit

Lists the audit classes that are audited for this user. Modifications to the system-wide classes are prefixed by a caret (^). Classes that are added to the system-wide classes are not prefixed by a caret.

never-audit

Lists the audit classes that are never audited for the user, even if these audit events are audited system-wide. Modifications to the system-wide classes are prefixed by a caret (^).

* Process preselection mask – A combination of the system-wide audit mask and the user-specific audit mask, if a user audit mask has been specified. When a user logs in, the login process combines the preselected classes to establish the process preselection mask for the user's processes. The process preselection mask specifies whether events in each audit class are to generate audit records.

The following algorithm describes how the system obtains the user's process preselection mask:

(system-wide default flags + always-audit-classes) - never-audit-classes

* getent user_attr

getent

- get entries from administrative database

getent gets a list of entries from the administrative database specified by database. The information generally comes from one or more of the sources that are specified for the database in /etc/nsswitch.conf.
