1z0-590 Oracle VM 3 for x86 Essentials Questions and Answers

Only one VM at a time will be migrated.

Place the new server into maintenance mode prior to begin migration.

Add the new server to the existing server pool.

Verify that both server involve in the live migration are identical (makes and model of hardware).

Publish the new IP addresses for all virtual machines following the migration.

Create a new server pool and preparation for the live migration.

Place the server (on which we schedule an outage) into maintenance mode to begin live migration.

First the VM files are migrated between the servers, then the memory, then the CPU registers.

First the VM files are migrated between the servers, then the memory.

First the memory is migrated between the servers, and then the CPU registers.

Only memory is migrated.

Use the xm save command to save the initial template in pristine form, then use xm restore to bring it back to the original configuration.

Use a snapshot of the initial template, and revert back to it whennecessary.

Use cleanup scripts to reset the IP addresses, remove files from temp directories, and replace application configuration files with defaults.

Modify the grub.conf file to include a -cleanup option in the grub command line, which will run the cleanup scripts added by Oracle.

Use JeOS with the -c option to include a cleanup script that will revert all files back to their initial state.

A netback driveris used in dom0, and a netfront driver is used in the guest.

A native device driver is used in dom0, and a netback driver is used in the guest.

A netfront driver is used in dom0, and a native device driver is used in the guest.

A netfront driveris used in dom0, and a blkbck driver is used in the guest.

Native drivers are used in both dom0 and the guest.

These templates provide development tools (such as gcc, ld, make) that are installed directly into Oracle VM dom0.

You want to customize your Oracle VM server with additional public software download from the internet.

You will need this running if you enter any service request to Oracle support services concerning your Oracle VM server.

You wish to provide an Oracle VM template development environment for Microsoft into guest to your development team.

You are a network hardware partner working with Oracle and need to compile a third party driver for a network interface card to integrate it into Oracle VM server but Oracle VM dom0 does not provide development tool.

Use PV with Microsoft's Windows 2003 64-bit with a paravirtualized kernel

Use HVM witha standard distribution of Windows 2003 and PV drivers.

Use emulation with the IOEMU drivers for better I/O performance.

Oracle VM does not support Windows 2003 Server. Use VirtualBox instead.

Oracle VM does not support Windows 2003 Server. Use Containers instead.

Oracle VM uses the same DLM (distributed lock manager) for NFS as it does for OCFS2 partitions.

The standard NFS drivers are sufficient to properly lock files in an NFS repository.

Oracle VM ships with the IO-EMU drivers, which provide proper locking for files on an NFS repository.

Oracle VM ships with a DM-NFS server, which runs on the master pool server and handles distributed file locking for an NFS repository.

Virtual machines will continue to run but they cannot be stopped.

Virtual machines will continue to run but they will have limited network access until the repository restored to the services.

Virtual machines will continue to run but Oracle VM manager will not be functional until the manager repository is restored to the services.

Virtual machines will be automatically suspended until the repository restored to services.

The database repository should be restored to service ASAP because degradation in performance and availability of Oracle VM servers and their guest virtual machine will begin to occur.

Certain management functions include template management and vnicmanagement may be extremely difficult or impossible to perform.

It connects to a pool of virtual machines with a RDP service.

It connectsto any virtual or any physical machine with a RDP service.

It connects to any physical machine regardless of operating system.

It connects to any virtual or any physical machine with a VNC service.

The ISO images should each be placed in their ownsubdirectory under/OVS/iso_pool.

The ISO images should be joined into one larger ISO image using the M75cat command, then placed under a subdirectory of/OVS/iso_pool.

The ISO images should all be placed under/OVS/iso_pool, using distinct names to differentiate them.

The ISO images should be placed in one subdirectory under/OVS/seed_pool, named according to the vendor and distribution name.

The ISO images should be placed in one subdirectory under/OVS/iso_pool, named according to the vendor and distribution name.

Oracle Validated Configurations provide testing of a "completecomponent stack" andrecommendations on versions, settings, and fixes for the particular stack (software, hardware, and storage) based on running workloads in Oracle's or a partner's test lab.

Oracle Validated Configurations are a mandatory step in Oracle's certification process.

Oracle Validated Configurations are working samples of hardware and software configurations in an Oracle VM environment.

All validated configurations must be run in Oracle's lab.

Oracle Validated Configurations are potential examples of hardware and software configurations whose specifications are validated by Oracle.

Create a partition of 250GB and use it as local OCFS2 file system and repository.

Create a partition with 50% of free space and use itas a local OCFS2 file system and repository.

Create a software mirror of a default partition to provide the redundancy and leave the remaining space unused.

Create a partition of 240GB and mount it.

Leave the reaming space unused.

Oracle VM 3.x has multiple identical storage repositories. Additional identical repositories can be added as needed. A best practice is to select a medium size for the repository based on your usage.

The way to grow an Oracle VM 3.x storage repository is to add additional space to the rootrepository as needed. A best practice is to only configure additional space when determined it is needed.

Oracle VM 3.x has a single fixed storage repository. A best practice is to configure the repository with 30%-40% headroom forgrowth.

The way to grow an Oracle VM 3.x storage repository is to add sub-repositories beneath the root repository. A best practice is to provision one or more larger repositories to avoid the management overhead of numerous sub-repositories.

The virtual machine I/O path only uses the block device driver from dom0.

The virtual machine relies onemulation of the hardware in dom0 for block I/O.

The virtual machine I/O path includes the native block device drivers from the guest operatingsystem.

The virtual machine does not need a block device driver.

The virtual machine must provide emulation of the hardware through its own IOEMU drivers.
