A customer is running an existing server farm of open source Xen servers running the same version of Xen as Oracle VM 2.2. The customer would like to manage these servers with Oracle VM.
What is the best reason that this will not be possible?
A. Oracle VM's Xen implementation uses a different disk format for virtual machines than open source Xen, so live migration of virtual machines will not work between the existing Xen implementation and Oracle VM.
B. Oracle VM employs a layer of technology on top of Xen that enables remote management through Oracle VM Manager or Oracle Enterprise Manager. The existing Xen servers are incapable of communicating in this manner.
C. Oracle VM uses a forked Xen distribution, so although the version numbers are the same, the behavior of the virtual machines at run time will be different.
D. Oracle VM uses a highly proprietary protocol format for Live Migration that enables strongencryption. Standard Xen servers will not be able to live migrate to the Oracle VM servers, or vice versa.
When vitalizing a cluster of Windows 2003 servers on Oracle VM, which virtualization technique should be used?
A. Use PV with Microsoft's Windows 2003 64-bit with a paravirtualized kernel
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.
A RedHat Enterprise Linux installation with three installation CDs needs to be created. What is the proper way to set up the ISO images?
A. The ISO images should each be placed in their own subdirectory under/OVS/iso_pool.
B. The ISO images should be joined into one larger ISO image using the M75cat command, then placed under a subdirectory of/OVS/iso_pool.
C. The ISO images should all be placed under/OVS/iso_pool, using distinct names to differentiate them.
D. The ISO images should be placed in one subdirectory under/OVS/seed_pool, named according to the vendor and distribution name.
E. The ISO images should be placed in one subdirectory under/OVS/iso_pool, named according to the vendor and distribution name.
What is the effect of running repos.py with the --delete option on an existing repository?
A. The repository will be unmounted, and the virtual machines will remain on the unmounted volume.
B. The repository will be unmounted, and all virtual machines on the unmounted volume will be deleted.
C. The repository will be unmounted, and all virtual machines on the repository will be migrated to other available repositories.
D. The repository will remain mounted, but all files in the volume will be deleted.
E. The repository will remain mounted, but it will no longer be available using the repos.py --list command.

During installation of Oracle VM Manager to a new Oracle Enterprise Linux server, the installer fails with a message indicating that there is insufficient swap space.
What is the cause for this error?
A. The installer has determined that the Oracle application server's (OC4J) minimum requirement for swap space has not been met.
B. The installer has determined that the Oracle Database XE server's minimum requirement for swap space has not been met.
C. The installer has determined that there is insufficient swap space to unpack the installer into the /var subdirectory.
D. The installer has determined that the swap space recognized by the system has been incorrectly formatted to use TMPFS instead of SWAPFS.
