Pass the Oracle Solaris 1z0-822 Questions and answers with ExamsMirror

Set the default scheduler for the system to be the FSS.

# dispadmin -d FSS

Create the etherstub.

global# dladm create-etherstub etherstub

Create a VNIC over the etherstub.

global# dladm create-vnic -l etherstub vnic

Note: Etherstubs / Virtual Switches

The Etherstub is craeated as a dummy device to connect the various virtual NICs. User can imagine etherstub as a Virtual Switch to help visualize the virtual network as a replacement for a physical network where each physical switch is replaced by a virtual switch.

Dump Parameter: minimum free space

Minimum amount of free space required in the savecoredirectory after

saving crash dump files. If no minimum free space has been configured, the

default is one Mbyte.

C: a user must be assigned to a default project, the processes that the user launches can be associated with any of the projects of which that user is a member.

D: How to Create a New Task

1.Log in as a member of the destination project, booksite in this example.

2.Create a new task in the booksite project by using the newtask command with the -v (verbose) option to obtain the system task ID.

machine% newtask -v -p booksite

16

The execution of newtask creates a new task in the specified project, and places the user's default shell in this task.

3.View the current project membership of the invoking process.

machine% id -p

uid=100(mark) gid=1(other) projid=4113(booksite)

The process is now a member of the new project.

Note:

* Projects are collections of tasks, which are collections of processes.

* Projects and tasks are used to label workloads and separate them from one another.

Incorrect:

Not A: The task collects a group of processes into a manageable entity that represents a workload component.

Not E: If no default project is found, the user's login, or request to start a process, is denied.

Disabled in the MODE column means that all probe-based failure detection is disabled.

You must enable transitive probing to use this failure detection method that does not require test addresses.

Note:

* ipmpstat

- display IPMP subsystem status

The ipmpstat command concisely displays information about the IPMP subsystem.

The -t option identifies the probe targets that are associated with each IP interface in an IPMP group.

* Target mode displays IPMP probe target information. The following output fields are supported:

/ INTERFACE

The IP interface name associated with the information.

/ MODE

The probe target discovery mode:

routes

Probe targets found by means of the routing table.

multicast

Probe targets found by means of multicast ICMP probes.

disabled

All probe-based failure detection is disabled.

transitive

Failure detection is by means of transitive probing, where the health of the IP interface is determined by probing other active interfaces in the group.

/ TESTADDR

The source address used in outgoing probes. Active interfaces that are being used for data traffic, as well as interfaces that have been explicitly configured with NOFAILOVER test addresses, will have the hostname (or IP address) that is used for sending and receiving the ICMP probes. All other interfaces in the group will display the name of the interface from which the probes are sent. Note that if an active IP interface is configured with both IPv4 and IPv6 test addresses, probe target information will be displayed separately for each test address.

/ TARGETS

A space-separated list of probe target hostnames (or IP addresses) for ICMP probes, or target interfaces for transitive probes. The IP targets will be listed in firing order, and, if no probe targets could be found, this field will be empty.

zonecfg subcommand info:

info zonename | zonepath | autoboot | brand | pool | limitpriv

info [resource-type [property-name=property-value]*]

Display information about the current configuration. If resource-type is specified, displays only information about resources of the relevant type. If any property-name value pairs are specified, displays only information about resources meeting the given criteria. In the resource scope, any arguments are ignored, and info displays information about the resource which is currently being added or modified.

Incorrect:

Not A: priocntl- process scheduler control

The priocntl() function provides for control over the scheduling of an active light weight process (LWP).

Not C: rctladm- display and/or modify global state of system resource controls.

The rctladm command allows the examination and modification of active resource controls on the running system.

Not D: prctl

- get or set the resource controls of running processes, tasks, and projects

The prctl utility allows the examination and modification of the resource controls associated with an active process, task, or project on the system. It allows access to the basic and privileged limits on the specified entity.

Gathering Statistics About Network Traffic on Flows

Flow statistics help you evaluate packet traffic on any defined flows on the system. To obtain flow information, you use the flowstat command.

* Display statistics about incoming and outgoing packets on all flows.

# flowstat

This command provides a static display of traffic information on all configured flows.

Incorrect:

Not A: In computing, sar (System Activity Report) is a Solaris-derived system monitor command used to report on various system loads, including CPU activity, memory/paging, device load, network.

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.

How to Re-create a ZFS Root Pool and Restore Root Pool Snapshots

1. Boot from an installation DVD or the network.

2. Mount the remote snapshot file system if you have sent the root pool snapshots as a file to the remote system.

3. If the root pool disk is replaced and does not contain a disk label that is usable by ZFS, you must relabel the disk.

4. Re-create the root pool.

5. Restore the root pool snapshots.

6. Verify that the root pool datasets are restored.

7. Set the bootfs property on the root pool BE.

8. Install the boot blocks on the new disk.

9. Reboot the system.
