1z0-580 Oracle Solaris 11 Installation and Configuration Essentials Questions and Answers

To ensure the system boots without starting the installation, make sure the entry you choose to boot does not have the install=true boot property specified in its kernel line.

B:Example:Creating a Policy Around a Mission-Critical Port

The command below creates a policy around inbound HTTPS traffic on an HTTPS server so that HTTPS obtains dedicated NIC hardware and kernel TCP/IP resources. The name specified, https-1, can be used later to modify or delete the policy.

# flowadm add-flow -l bge0 -a transport=TCP,local_port=443 https-1

# flowadm show-flow -l bge0

FLOW LINK IP ADDR PROTO PORT RPORT DSFLD

https1 bge0 -- tcp 443 -- --

Note:

*Flow Restrictions Per Zone

Within a zone, no two flows can have the same name. After adding a flow with the link specified, the link will not be required for display, modification, or deletion of the flow.

Incorrect:

Not A:Flow Properties

The following flow properties are supported. Note that the ability to set a given property to a given value depends on the driver and hardware.

maxbw

Sets the full duplex bandwidth for the flow. The bandwidth is specified as an integer with one of the scale suffixes(K, M, or G for Kbps, Mbps, and Gbps). If no units are specified, the input value will be read as Mbps. The default is no bandwidth limit.

priority

Sets the relative priority for the flow. The value can be given as one of the tokens high, medium, or low. The default is medium.

Not D:The following types of combinations of attributes are supported:

local_ip[/prefixlen]=address

remote_ip[/prefixlen]=address

transport={tcp|udp|sctp|icmp|icmpv6}

transport={tcp|udp|sctp},local_port=port

transport={tcp|udp|sctp},remote_port=port

dsfield=val[:dsfield_mask]

On a given link, the combinations above are mutually exclusive. An attempt to create flows of different combinations will fail.

Note:Flow Attributes

The flow operand that identify a flow in a flowadm command is a comma-separated list of one or more keyword, value pairs from the list below.

local_ip[/prefix_len]

remote_ip[/prefix_len]

transport={tcp|udp|sctp|icmp|icmpv6}

local_port

Identifies a service specified by the local port.

remote_port

Identifies a service specified by the remote port.

dsfield[:dsfield_mask]

NotE:

*flowstat

- report flow statistics

*The flowstat command reports run time statistics about user defined flows. flowadm show-flow provides the flow name information for this command.

*flowstat [-r | -t] [-i interval] [-l link] [flow]

This form of the command iteratively examines all flows and reports statistics. The output is sorted in descending order of flow utilization. If no flow is specified, the system displays statistics for all flows.

-r

Display receive-side statistics only. Includes bytes and packets received, drops, and so forth.

-t

Display transmit-side statistics only. Includes bytes and packets sent, drops, and so forth.

-i interval

Specify an interval in seconds at which statistics are refreshed. The default interval is one second.

-l link | flow]

Display statistics for all flows on the specified link or statistics for the specified flow.

Incorrect:

not A:IPS relies on network-accessible or locally available software repositories as a delivery

mechanism, which is similar to how other operating systems (notably Oracle Linux) supply

software updates.

not D: can be done with the pkg command.

Note:

*Image Packaging System (IPS) is a new network based package management system included in Oracle Solaris 11. It provides a framework for complete software lifecycle management such as installation, upgrade and removal of software packages.

Safe system upgrades with ZFS boot environments

Network package repositories of software

Efficient downloads and automatic dependency checking

Support for disconnected data center environments

Extensive package publishing tools

Note:

*sendmail

*Enabling Access to Remote Clients

On an unmodified system, access to sendmail by remote clients is enabled and disabled through the service management facility (see smf(5)). In particular, remote access is determined by the value of the local_only SMF property:

svc:/network/smtp:sendmail/config/local_only = true

A setting of true, as above, disallows remote access; false allows remote access. The default value is true.

The following example shows the sequence of SMF commands used to enable sendmail to allow access to remote systems:

# svccfg -s svc:/network/smtp:sendmail setprop config/local_only = false

# svcadm refresh svc:/network/smtp:sendmail

# svcadm restart svc:/network/smtp:sendmail

An M represents a modified file or directory, an R is a renamed filesystem objects.

The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11.1 environment without installing it on a system. The system boots off the media directly allowing administrators to start the installer should they choose to install it to a system.

Note:

*You have several alternatives for where to install Oracle Solaris 11:

Inside a virtual machine on top of your existing operating system

On the bare metal as a standalone operating system

On the bare metal alongside your existing operating system(s) (multiboot scenario)

pkgrecv

- Image Packaging System content retrieval utility

Options include:

-c cache_dir

The path to a directory that will be used to cache downloaded content. If this directory is not supplied, the client automatically selects a cache directory. In the case where a download is interrupted, and a cache directory was automatically chosen, use this option to resume the download. See the “Environment Variables” section below for details about how to set the location used for temporary data storage.
