1z0-822 Practice Test

Use ipadm create-addr to add the address to a member interface.

Verify that netadm includes the Network Management profile.

Add a line for the ssh-keygen command to the file auth_attr.d/local-entries.

Explanation:
D: /etc/security/auth_attr is a local source for authorization names and descriptions.
An authorization is a right assigned to users that is checked by certain privileged programs
to determine whether users can execute restricted functionality.

The minfree value can be to protect a percentage of available disk space.

Explanation: See % below.
coredump parameter: -m mink | minm | min%
Create a minfree file in the current savecore directory indicating that savecore should
maintain at least the specified amount of free space in the file system where the savecore
directory is located. The min argument can be one of the following:
k
A positive integer suffixed with the unit k specifying kilobytes.
m
A positive integer suffixed with the unit m specifying megabytes.
%
A % symbol, indicating that the minfree value should be computed as the specified
percentage of the total current size of the file system containing the savecore directory.

The savecore command will consult the minfree file, if present, prior to writing the dump
files. If the size of these files would decrease the amount of free disk space below the
minfree threshold, no dump files are written and an error message is logged. The
administrator should immediately clean up the savecore directory to provide adequate free
space, and re-execute the savecore command manually. The administrator can also
specify an alternate directory on the savecore command-line.
Incorrect:
Not C: Separate ZFS volumes must be used for the swap area and dump devices.

Explanation: The zfs get command supports the -H and -o options, which are designed for
scripting. You can use the -H option to omit header information and to replace white space
with the Tab character. Uniform white space allows for easily parseable data. You can use
the -o option to customize the output in the following ways:
* The literal name can be used with a comma-separated list of properties as defined in the
Introducing ZFS Properties section.
* A comma-separated list of literal fields, name, value, property, and source, to be output
followed by a space and an argument, which is a comma-separated list of properties.
The following example shows how to retrieve a single value by using the -H and -o options
of zfs get:
# zfs get -H -o value compression tank/home

Edit the /etc/default./mpathd file and set TRACK_INTERFACES_ONLY_WITH
GROUPS=no.

Explanation: * /etc/default/mpathd
Contains default values used by the in.mpathd daemon.
* By default, in.mpathd limits failure and repair detection to IP interfaces that are configured
as
part of a named IPMP group. Setting TRACK_INTERFACES_ONLY_WITH_GROUPS to
no enables failure and repair detection on all IP interfaces, even if they are not part of a
named IPMP group. IP interfaces that are tracked but not part of a named IPMP group are
considered to be part of the “anonymous” IPMP group. In addition to having no name, this
IPMP group is
special in that its IP interfaces are not equivalent and thus cannot take over for one another
in the event of an IP interface failure. That is, the anonymous IPMP group can only be used
for
failure and repair detection, and provides no high-availability or load-spreading
