1z0-821 Exam Dumps - Oracle Solaris 11 System Administration

* Updating all of the packages on your installed system – To update all of the packages on your system that have available updates, use the pkg update command, as follows:

# pkg update

Running this command updates packages that you might not otherwise consider updating, for example, kernel components and other low-level system packages.

* Adding or updating individual packages – To add individual software packages, use the pkg install command. Any dependent packages are also updated at the same time.

* install package updates that deliver fixes– A pkg update operation might include bug fixes, so the operation is similar to applying a specific patch or patches in previous Oracle Solaris releases.

Note: The IPS interfaces first check for updates for currently installed packages before retrieving them via the network. By default, interfaces check repository catalogs in the following locations:

* The default installation repository at pkg.oracle.com/solaris/release.

* The support repository in My Oracle Support. This repository is restricted to users with Oracle Solaris 11 Express support contracts, and it contains packages with the latest bug fixes. For this reason, a support contract must be purchased for production deployments.

D: zoneadm halt command halts the specified zones. halt bypasses running the shutdown scripts inside the zone. It also removes run time resources of the zone.

E: Use: zlogin zone shutdown

to cleanly shutdown the zone by running the shutdown scripts.

Use this procedure to cleanly shut down a zone.

1. Become superuser, or assume the Primary Administrator role.

2. Log in to the zone to be shut down, for example, my-zone, and specify shutdown as the name of the utility and init 0 as the state global# zlogin my-zone shutdown -y -g0 -i 0

A: How to Log In to the Zone Console Use the zlogin command with the -C option and the name of the zone, for example, my-zone.

global# zlogin -C my-zone

C: To disconnect from a non-global zone, use one of the following methods.

* To exit the zone non-virtual console:

zonename# exit

* To disconnect from a zone virtual console, use the tilde (~) character and a period:

zonename# ~.

Use the chmod command to change permissions for a file or directory. You must be the owner of a file or directory, or have root access, to change its permissions.

Solaris: Solaris Advanced User's Guide

By default, Solaris will boot to the pseudo milestone “all” and start all services. This behaviour can be changed at boot time using either “-s” to reach single-user, or the new SMF option “-m milestone=XXX” (see kernel(1M) for a list of the bootable milestones) to select an explicit milestone.

Note: boot -s is the same as: boot -m milestone=single-user

with the difference being that the former is a lot less to type and is what most SysAdmins will be familiar with.

The svcs command displays information about service instances as recorded in the service configuration repository.

-d Lists the services or service instances upon which the given service instances depend.

According to the exhibit the interface already exists.

The command ipadm create-ip net3 is supposed to create a new interface net3.

A: Non-global zones can not utilize DHCP (neither client nor server).

B (not C): By default, non-global zones will be configured with a shared IP functionality. What this means is that IP layer configuration and state is shared between the zone you’re creating and the global zone. This usually implies both zones being on the same IP subnet for each given NIC.

Note: A zone is a virtual operating system abstraction that provides a protected environment in which applications run. The applications are protected from each other to provide software fault isolation. To ease the labor of managing multiple applications and their environments, they co-exist within one operating system instance, and are usually managed as one entity.

The original operating environment, before any zones are created, is also called the "global zone" to distinguish it from non-global zones, The global zone is the operating system instance.

Incorrect answer:

E: Exclusive-IP zones can use IPMP. IPMP is configured the same way in an exclusive-IP zone as it is on a system not using zones.

For shared-IP zones, IPMP can be configured in the global zone.

F: Full IP-level functionality is available in an exclusive-IP zone.

An exclusive-IP zone has its own IP-related state.

An exclusive-IP zone is assigned its own set of data-links using the zonecfg command. The zone is given a data-link name such as xge0, e1000g1, or bge32001, using the physical property of the net resource. The address property of the net resource is not set.

Note that the assigned data-link enables the snoop command to be used.

The dladm command can be used with the show-linkprop subcommand to show the assignment of data-links to running exclusive-IP zones.
