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

*vnic-link

A virtual network interface created on a link or an etherstub. It is a pseudo device that can be treated as if it were an network interface card on a machine.

*vlan-link

A VLAN datalink.

*bridge

A bridge instance, identified by an administratively-chosen name. The name may use any alphanumeric characters or the underscore, _, but must start and end with an alphabetic character. A bridge name can be at most 31 characters. The name default is reserved, as are all names starting with SUNW.

Note:

*dladm– administer data links

*The dladm command is used to administer data-links. A data-link is represented in the system as a STREAMS DLPI (v2) interface which can be plumbed under protocol stacks such as TCP/IP. Each data-link relies on either a single network device or an aggregation of devices to send packets to or receive packets from a network.

Each dladm subcommand operates on one of the following objects:

link

A datalink, identified by a name. In general, the name can use any alphanumeric characters (or the underscore, _), but must start with an alphabetic character and end with a number. A datalink name can be at most 31 characters, and the ending number must be between 0 and 4294967294 (inclusive). The ending number must not begin with a zero. Datalink names between 3 and 8 characters are recommended.

Some subcommands operate only on certain types or classes of datalinks. For those cases, the following object names are used:

phys-link

A physical datalink.

vlan-link

A VLAN datalink.

aggr-link

An aggregation datalink (or a key; see NOTES).

ether-link

A physical Ethernet datalink.

wifi-link

A WiFi datalink.

vnic-link

A virtual network interface created on a link or an etherstub. It is a pseudo device that can be treated as if it were an network interface card on a machine.

iptun-link

An IP tunnel link.

dev

A network device, identified by concatenation of a driver name and an instance number.

etherstub

An Ethernet stub can be used instead of a physical NIC to create VNICs. VNICs created on an etherstub will appear to be connected through a virtual switch, allowing complete virtual networks to be built without physical hardware.

bridge

A bridge instance, identified by an administratively-chosen name. The name may use any alphanumeric characters or the underscore, _, but must start and end with an alphabetic character. A bridge name can be at most 31 characters. The name default is reserved, as are all names starting with SUNW.

Note that appending a zero (0) to a bridge name produces a valid link name, used for observability.

secobj

A secure object, identified by an administratively-chosen name. The name can use any alphanumeric characters, as well as underscore (_), period (.), and hyphen (-). A secure object name can be at most 32 characters.

How to Loopback Mount a File That Is Usually Not Visible in a Labeled Zone

This procedure enables a user in a specified labeled zone to view files that are not exported from the global zone by default.

• Halt the zone whose configuration you want to change.

# zoneadm -z zone-name halt

• Loopback mount a file or directory.

For example, enable ordinary users to view a file in the /etc directory.

# zonecfg -z zone-name

add filesystem

set special=/etc/filename

set directory=/etc/filename

set type=lofs

add options [ro,nodevices,nosetuid]

end

exit

Note - Certain files are not used by the system, so that loopback mounting them has no effect. For example, the /etc/dfs/dfstab file in a labeled zone is not checked by Trusted Extensions software. For more information, see Sharing Files From a Labeled Zone.

• Start the zone.

# zoneadm -z zone-name boot

Note:

*In this Solaris release, you create a ZFS file system share and publish the share as follows:

Create the file system share and define the NFS or SMB share properties by using the zfs share command.

*ZFS File Sharing Within a Non-Global Zone

In previous Solaris releases, you could not create and publish NFS or SMB shares in a Oracle Solaris non-global zone. In this Solaris release, you can create and publish NFS shares by using the zfs set share command and the legacy share command with a non-global zone.

*If a ZFS file system is mounted and available in a non-global zone, it can be shared in that zone.

*A file system can be shared in the global zone if it is not mounted in a non-global zone or is not shared to a non-global zone.

*If a ZFS file system's mountpoint property set to legacy, the file system can be shared by using the legacy share command.

Incorrect:

Not B:With a single vendor providing all the elements for an application platform, finger pointing is eliminated and problem resolution takes less time.

Note:

*Oracle’s product research and engineering expertise spans the entire stack — from storage,

networks, compute and operating systems, to middleware, enterprise applications and

databases — and is integrated and validated to work together to take the guesswork out of

deploying complex solutions.

*Oracle is the only high technology company with all the software

and hardware components to deliver an infrastructure that can transform and streamline business

operation. Indeed, Oracle’s application-to-disk stack is so well integrated and tuned that it

provides less risk, better performance, and easier management for application environments

*Oracle’s end-to-end solution stack includes Oracle’s innovative servers and storage systems, the industry’s only end-to-end virtualization portfolio, robust Oracle Solaris and Oracle Linux operating environments, Oracle Database, middleware, premier enterprise applications, and industry-leading management tools. For years, Oracle has strived to integrate, test, and certify these technologies to work together to deliver the functionality, performance, security, and reliability companies can depend on to get the job done.

*The Oracle integrated stack.

B:Built-in Virtualization

Whatever the needs of your cloud infrastructure, Oracle has a comprehensive suite of built-in virtualization technologies to compliment your business requirements. 

Choose from Oracle Solaris Zones, OVM Server for SPARC, OVM Server for x86 and OVM VirtualBox. With Oracle Solaris Zones, administrators can rapidly provision secure and isolated virtual environments in which to deploy cloud applications and services.

D:

Oracle Solaris is the best platform for the cloud because it combines key computing elements - operating system, virtualization, networking, storage management, and user environment - into a stable, secure, mission-critical foundation that customers can depend on

TFTP Error or System Hangs After GATEWAY Message

The DHCP server provides an IP address and a location of the initial boot program as part of the DHCP response.

If the boot program does not exist, then the AI client boot cannot proceed. The following message is displayed:

Intel(R) Boot Agent PXE Base Code (PXE-2.1 build 0.86)

Copyright(C) 1997-2007, Intel Corporation

CLIENT MAC ADDR 00 14 4F 29 04 12 GUID FF2000008 FFFF FFFF FFFF 7BDA264F1400

CLIENT IP: 10.6.68.29 MASK: 255.255.255.0 DHCP IP: 10.6.68.49

TFTP.

PXE-T02: Access Violation

PXE-E3C: TFTP Error - Access violation

PXE-MOF: Exiting Intel Boot Agent

To patch a Solaris system or install a command you use pkg command.

*Use the configuration element in the AI manifest for the client system to specify non-global zones.

Use the name attribute of the configuration element to specify the name of the zone.

Use the source attribute to specify the location of the config file for the zone.

The source location can be any http:// or file:// location that the client can access during installation.

*The following sample AI manifest specifies two Non-Global Zones: zone1 and zone2

You should replace the server_ip with the ip address of the NFS server.

name="http://pkg.oracle.com/solaris/release"/ >

pkg:/entire@latest

pkg:/group/system/solaris-large-server

B: The disk intended for the root pool must have an SMI label. Otherwise, the installation will fail.

D:The default target location for the installation is the first disk found on each client that meets the size requirement. If the size of a disk is greater than or equal to the recommended size, the installer selects that disk as the installation target. If the size of the disk is less than the recommended size, the installer checks the next disk. If no disk is found that meets the size requirement, the automated installation fails for that client.

Note:

*If you do not specify a target location on a client for installing the Oracle Solaris OS, AI selects a default target.

Incorrect:

not A: and  – Optional. You can use AI to configure swap and dump during the automated install.

Not C: A mirrored dataset for the root pool is not required.
