1Z0-580 Exam Questions & Answers

Storage

ZFS is the root file system on Oracle Solaris 11 offering a superior experience in terms of manageability, scalability and data integrity. ZFS presents a pooled storage model that completely eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted bandwidth and stranded storage. Thousands of file systems can draw from a common storage pool, each one consuming only as much space as it actually needs. All operations are copy-on-write transactions ensuring that the on-disk state is always valid.

Incorrect:

Not A: Network Auto-Magic (NWAM) is a project to simplify and automate network configuration on Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify various network configurations to be created depending on the current network conditions. The Service Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network Auto-Magic umbrella.

Not B: Pre-Flight Checker tool which can be used to check whether apps will work without modification on Solaris 11

Not C: Network Auto-Magic is a project to simplify and automate network configuration on Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify various network configurations to be created depending on the current network conditions. The Service Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network Auto-Magic umbrella.

Note:

Not A:

* Jumpstart Profiles and Rules would have to be converted to be used in Automated Installer.

Use the js2ai utility with the -r option to convert both JumpStart rules and their associated profiles to AI criteria and manifests.

* Both Solaris Custom JumpStart and Oracle Solaris Automated Installer (AI) provide hands-free installation of multiple systems on a network. Clients are booted over the network, and once the client is booted, the installer takes over.

How to Use DTrace in a Non-global Zone

1. Use the zonecfg limitpriv property to add the dtrace_proc and dtrace_user privileges.

global# zonecfg -z my-zone

zonecfg:my-zone> set limitpriv='default,dtrace_proc,dtrace_user'

zonecfg:my-zone> exit

Note --

Depending on your requirements, you can add either privilege, or both privileges.

2. Boot the zone.

3. global# zoneadm -z my-zone boot

Log in to the zone.

global# zlogin my-zone

4. Run the DTrace program.

my-zone# dtrace -l

Note:

* Oracle Solaris DTrace is a comprehensive, advanced tracing tool for troubleshooting systemic problems in real time.

* DTrace helps you understand a software system by enabling you to dynamically modify the operating system kernel and user processes to record additional data that you specify at locations of interest, called probes.

A: dedicated-cpu Resource

The dedicated-cpu resource specifies that a subset of the system's processors should be dedicated to a non-global zone while it is running. When the zone boots, the system will dynamically create a temporary pool for use while the zone is running.

C: s the global administrator in the global zone, you can import raw and block devices into a non-global zone. After the devices are imported, the zone administrator has access to the disk. The zone administrator can then create a new file system on the disk and perform one of the following actions:

Mount the file system manually

Place the file system in /etc/vfstab so that it will be mounted on zone boot

D, E: Booting a zone places the zone in the running state. A zone can be booted from the ready state or from the installed state. A zone in the installed state that is booted transparently transitions through the ready state to the running state. Zone login is allowed for zones in the running state.

Incorrect:

Not F: Sys_time not related to booting a zone.

The following table lists different tasks for planning the network configuration.

* (A) Identify the hardware requirements of your planned network topology.

Determine the types of equipment that you need for your network site.

*(C) Determine the type of IP addresses to use and obtain registered IP addresses.

Select whether you are deploying a purely IPv4 network, an IPv6 network, or a network that uses both types of IP addresses. Obtain unique IP addresses to communicate to public networks in the Internet.

* (D) Determine a naming scheme to identify the hosts in the network as well as the name service to use.

Create a list of names to assign to the systems on the network and decide whether to use NIS, LDAP, DNS, or the network databases in the local /etc directory.

* If necessary, establish administrative subdivisions and design a strategy for subnets.

Decide if your site requires that you divide your network into subnets to service administrative subdivisions

* Determine where to place routers in the network design.

If your network is large enough to require routers, create a network topology that supports them.

* Decide whether to create virtual networks in the overall network configuration scheme.

You might need to create virtual networks within a system to reduce the hardware footprint of your network.
