Note the first line:

global core file pattern: /globalcore/core.%f.%p

The program name is bash

The runtime process ID is 2663

Note: By default, the global core dump is disabled. You need to use the coreadm command with the -e global option to enable it. The -g option causes the command to append the program name(%f) and the runtime process ID (%p) to the core file name.

If you're logged on to the system, you can run prstat -Z to generate a summary of cpu/memory utilization by zone.

The pkg info command provides detailed information about a particular IPS package.

Note: The pkginfo command does the same for any SVR4 packages you may have installed on the same system.

pkg info example:

$ pkg info p7zip

Name: compress/p7zip

Summary: The p7zip compression and archiving utility

Description: P7zip is a unix port of the 7-Zip utility. It has support for numerous compression algorithms, including LZMA and LZMA2, as well as for various archive and compression file formats, including 7z, xz, bzip2, gzip, tar, zip (read-write) and cab, cpio, deb, lzh, rar, and rpm (read-only).

An image is a location where packages can be installed.

An image can be one of three types:

* Full images are capable of providing a complete system.

* Partial images are linked to a full image (the parent image), but do not provide a complete system on their own.

* User images contain only relocatable packages.

* 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.

The User Datagram Protocol (UDP) is one of the core members of the Internet Protocol Suite, the set of network protocols used for the Internet. With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up special transmission channels or data paths.

Compared to TCP, UDP is a simpler message-based connectionless protocol.

First the full backup must be restored. This would be the Sunday backup.

Then the last incremental backup must be restored. This would be the Wednesday backup.

Before restoring the Wednesday incremental file system snapshot, the most recent snapshot must first be rolled back.

By exclusion D) would be best answer even though it is incomplete.

Audit Significant Events in Addition to Login/Logout (see step 2 below)

Use this procedure to audit administrative commands, attempts to invade the system, and other significant events as specified by your site security policy.

For all users and roles, add the AUE_PFEXEC audit event to their preselection mask.

# usermod -K audit_flags=lo, ps:no username

# rolemod -K audit_flags=lo, ps:no rolename

# auditconfig -setpolicy +argv

3- Record the environment in which audited commands are executed.

# auditconfig -setpolicy +arge

Note: [-t] -setpolicy [+|-]policy_flag[, policy_flag ...]

Set the kernel audit policy. A policy policy_flag is literal strings that denotes an audit policy. A prefix of + adds the policies specified to the current audit policies. A prefix of - removes the policies specified from the current audit policies. No policies can be set from a local zone unless the perzone policy is first set from the global zone.

Note 1: State Transition Sets are defined as:

to

Set of all transitions that have as the final state of the transition.

form-

Set of all transitions that have as the initial state of the transition.

Set of all transitions that have as the initial state of the transitional.

Set of all transitions. (A)

Valid values of state are maintenance, offline (G), disabled (E), online and degraded. An example of a transitions set definition: maintenance, from-online, to-degraded.

F: In this context, events is a comma separated list of SMF state transition sets or a comma separated list of FMA (Fault Management Architecture) event classes. events cannot have a mix of SMF state transition sets and FMA event classes. For convenience, the tags problem- {diagnosed, updated, repaired, resolved} describe the lifecycle of a problem diagnosed by the FMA subsystem - from initial diagnosis to interim updates and finally problem closure.

Note 2:

SMF allows notification by using SNMP or SMTP of state transitions. It publishes Information Events for state transitions which are consumed by notification daemons like snmp-notify(1M) and smtp-notify(1M). SMF state transitions of disabled services do not generate notifications unless the final state for the transition is disabled and there exist notification parameters for that transition. Notification is not be generated for transitions that have the same initial and final state.
