1z0-822 Dumps Questions With Valid Answers

Use the rctladm command to enable the global syslog attribute of a resource control.

Explanation: Global Monitoring of Resource Control Events
Often, the resource consumption of processes is unknown. To get more information, try
using the global resource control actions that are available with the rctladm command. Use
rctladm to establish a syslog action on a resource control. Then, if any entity managed by
that resource control encounters a threshold value, a system message is logged at the
configured logging level.

 pkg install --be-name BE2 top

 pkg set-property be-policy always-newpkg install top

Explanation: By default, a new BE is automatically created when you perform one of the
following operations:
* (D) Set the be-policy image policy to always-new. Under this policy, all package
operations are performed in a new BE set as active on the next boot.
* Update particular key system packages such as some drivers and other kernel
components. This can happen when you install, uninstall, update, change variant, or
change facet.
* Often a new BE is created when you execute the pkg update command to update all
packages that have updates available.
* Specify any of the following options: -be-name, -require-new-be, -backup-be-name, -
require-backup-be.

Fixed-priority (FX)

Explanation: The FX scheduler provides a scheduling policy for processes that require
user or application control of scheduling priorities. The priorities of processes that run
under FX are fixed.
The FX class provides a fixed-priority preemptive scheduling policy. This policy is used by
processes that require user or application control of scheduling priorities but are not
dynamically adjusted by the system. By default, the FX class has the same priority range
as the TS, IA, and FSS classes. The FX class allows user or application control of
scheduling priorities through user priority values assigned to processes within the class.
These user priority values determine the scheduling priority of a fixed-priority process
relative to other processes within its class.
Incorrect:
Not A: The fair share scheduling class enables you to allocate CPU time based on shares
instead of the priority scheme of the timesharing (TS) scheduling class.
Not D: The goal of the time-sharing policy is to provide good response time to interactive
processes and good throughput to CPU-bound processes. The scheduler switches CPU
allocation often enough to provide good response time, but not so often that the system
spends too much time on switching. Time slices are typically a few hundred milliseconds.
The time-sharing policy changes priorities dynamically and assigns time slices of different
lengths.

require_all

optional_all

Explanation: Service Dependency. This element identifies a group of FMRIs upon which
the service is in some sense dependent.
ATTRIBUTE: Grouping:
Possible values:
'require_all',
'require_any',
'exclude_all',
‘optional_all'
Note:

* Example 1:
<dependency
name='network'
grouping='require_all'
restart_on='none'
type='service'>
<service_fmri value='svc:/milestone/network:default' />
</dependency>
* In this example, let's choose the svc:/system/zones:default service instance. We can use
the -l option and the service name to get more information, as shown in Listing 3.
# svcs -l svc:/system/zones:default
