What is the effect of running a server pool restores?

A. When you restore a server pool, all the data stored in the Oracle VM Manager database Isdeleted, and the data in the server pool master and virtual machine servers is used to restock the database.

B. When you restore a server pool, all servers are removed from the pool, and the data in the database is removed, restoring the server pool to its initial state.

C. When you restore a server pool, all the data stored in the server pool master will be deleted, and will be synchronized with the latest information from the Oracle VM Manager database. The server pool master is responsible for updating the individual Oracle VM servers' agent databases.

D. When you restore a server pool, a signal is sent out to each server in the pool, which responds with the current state of all of the virtual machines it hosts. This data is used to restore the data in the Oracle VM database.

In hardware virtualized environment, which answer best describes the drivers that are used in dom0 and the guest to communicate block I/O requests?

A. QEMU emulation is used in dom0, and a blkfront driver is used in the guest.

B. A native device driver is used in dom0, and QEMU emulation is used in the guest.

C. A blkfront driver is used in dom0, and a blkback driver is used in the guest

D. QEMU emulation is used in dom0, and a native device driver is used in the guest.

E. Native drivers are used in both dom0, and the guest.

You have a large number of virtual machines that need access to a storage repository. Which answer describes the factors you use to determine your storage repository strategy?

A. 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.

B. 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.

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

D. 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.

In a paravirtualized environment, which answer best describes the drivers that are used in domO and the guest to communicate block I/O requests?

A. A blkback driver is used in dom0, and a blkfront driver is used in the guest.

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

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

D. A blkfront driver is used in dom0, and a blkbck driver is used in the guest.

E. Native drivers are used in both dom0 and the guest.

The Oracle VM administrator is having issues shutting down a virtual machine. Which log file will best help troubleshoot whether the shutdown command is being successfully executed on the target server?

B. Use HVM with a standard distribution of Windows 2003 and PV drivers.

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

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

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

B. xm show ovs-agent

C. service ovs-agent status

D. repos.py -1

E. xm dmesg

What two steps can be used to create a highly available storage repository?

A. Turn on HA in the storage pool to create a redundant backup of virtual machines hosted in thatstorage pool.

B. Use network bonding to create multiple redundant paths to an iSCSI LUN

C. Use multipathing to create multiple storage network paths to a SAN LUN.

D. Use Oracle Clusterware to create multiple paths to a SAN LUN.

E. Use Oracle Clusterware to create each storage repository on a different storage network.
