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.

C: If LACP (Link Aggregation Control Protocol) cannot aggregate all the ports that are compatible (for example, the remote system might have more restrictive hardware limitations), then all the ports that cannot be actively included in the channel are put in hot standby state and are used only if one of the channeled ports fails.

E: Link aggregations provide high availability and higher throughput by aggregating multiple interfaces at the MAC layer. IP Multipathing (IPMP) provides features such as higher availability at the IP layer. Both IPMP and Link Aggregation are based on the grouping of network interfaces, and some of their features overlap, such as higher availability. These technologies are however implemented at different layers of the stack, and have different strengths and weaknesses.

Incorrect:

Not A: MP is built into Oracle Solaris and does not require any special hardware. Any interface that is supported by Oracle Solaris can be used with IPMP. However, IPMP does impose the following requirements on your network configuration and topology:

/All interfaces in an IPMP group must have unique MAC addresses.

/ All interfaces in an IPMP group must be of the same media type.

/ All interfaces in an IPMP group must be on the same IP link

Not B: A switch, not a router, would be a single point of failure of link aggregation (as it works on the Mac layer and not on the IP layer.

not D: Internet Protocol Network Multipathing (IPMP) provides fault-tolerance and load balancing across multiple network interface cards. By using IPMP, you can configure one or more interfaces into an IP multipathing group. After configuring IPMP, the system automatically monitors the interfaces in the IPMP group for failure. If an interface in the group fails or is removed for maintenance, IPMP automatically migrates, or fails over, the failed interface's IP addresses

Solaris auditing keeps a record of how the system is being used. The audit service includes tools to assist with the analysis of the auditing data.

Incorrect:

not C: Basic Audit Reporting Tool

BART is a file tracking tool that operates entirely at the file system level. Using BART gives you the ability to quickly, easily, and reliably gather information about the components of the software stack that is installed on deployed systems. Using BART can greatly reduce the costs of administering a network of systems by simplifying time-consuming administrative tasks.

Note:

* The audit service makes the following possible:

Monitoring security-relevant events that take place on the host

Recording the events in a network-wide audit trail

Detecting misuse or unauthorized activity

Reviewing patterns of access and the access histories of individuals and objects

Discovering attempts to bypass the protection mechanisms

Discovering extended use of privilege that occurs when a user changes identity

* Auditing is the collecting of data about the use of system resources. The audit data provides a record of security-related system events. This data can then be used to assign responsibility for actions that take place on a host. Successful auditing starts with two security features: identification and authentication. At each login, after a user supplies a user name and password, a unique audit session ID is generated and associated with the user's process. The audit session ID is inherited by every process that is started during the login session. Even if a user changes identity within a single session, all user actions are tracked with the same audit session ID.

* policy.conf

policy.conf– configuration file for security policy.

The policy.conf file provides the security policy configuration for user-level attributes.

* Example: Modifying Every User's Basic Privilege Set

In this example, the security administrator of a large Sun Ray installation does not want regular users to view the processes of other Sun Ray users. Therefore, on every system that is configured with Trusted Extensions, the root role removes proc_info from the basic set of privileges. The PRIV_DEFAULT setting in the /etc/policy.conf file is uncommented and modified as follows:

PRIV_DEFAULT=basic,!proc_info

From the poolcfg –c info command output we see that FSS (Fair Share Scheduler) is used.

From the prctl command output we see that zone z1 has been configured with a zone.cpu-shares value of 40.

* The pool_default has a value of 100 CPU shares.

* prstat

- report active process statistics

Option –Z

-Z

Report information about processes and zones. In this mode, prstat displays separate reports about processes and zones at the same time.

Use one of the following methods to restart the depot server process:

B: Use svcadm(1M) to restart the application/pkg/server instance.

C: Send a SIGUSR1 signal to the depot server process using kill(1). This executes a “graceful restart” that leaves the process intact but reloads all configuration, package, and search data:

# kill -USR1 pid

Note:

* The pkd.depotd service is managed by SMF under the service identifier svc:/application/pkg/server.

zpool detach pool device

Detaches device from a mirror. The operation is refused if there

are no other valid replicas of the data.

A: To restart remote logging:

svccfg -s system-log setprop config/log_from_remote=true

svcadm restart system-log

D: You can run 'snoop' on the interface to see if you see syslog packets leaving the server

snoop udp port 514
