Which two are true of an NFS repository when used with Oracle VM?

A.

NFS repositories are excellent for storing guests' root file systems.

B.

NFS is a more expensive option than iSCSI or SAN fabrics.

C.

OCFS2 must be used as the filesystem format for volumes exposed through NFS.

D.

NFS shares mounted directly in a guest require the DM-NFS driver to be installed on the guest.

E.

NFS is supported for use in RAC only when mounted from the guest (not domO).

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 notwork 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 ofcommunicating 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.

What command(s) will create a new 10 GB virtual disk named Apps, and attach it to a virtual machine named Test?

A.

sd new -d 10240 -n Appsvm sd attach-n Test -d Apps

B.

sd new -d 10240 -n Appssd reg -n Apps vmsd attach -n Test -d Apps

C.

vm disk add -n Test -d Apps -S 10240

D.

Identify the three components of the JeOS tool kit.

A.

A command line utility to customize and create a system image.

B.

Microsoft template system image.

C.

Oracle Linux template system image.

A 64-bit Windows XP Installation CD has been ripped to an ISO file named WinXP.iso, and has been put in the /OVS/iso_pool/ directory with user and group-readable permissions. When navigating to the Import ISO screen in the Oracle VM Manager, no ISOs are available for import.

What has gone wrong?

A.

64-bit Windows XP is not a supported guest operating system, and the Oracle VM Manager will not show unsupported guest ISO files.

B.

The user has not selected the appropriate ISO Group on the Import form.

C.

The ISO file should be located under a subdirectory of /OVS/iso_pool, not the /OVS/iso_pool directory itself.

D.

The ISO file should be located under/OVS/seed_pool, not/OVS/iso_pool.

E.

The ISO file must have world-readable permission to be read by Oracle VM.

What command will show the current status of all Oracle VM Agent components?

A.

service ovs status

B.

After installing the PV drivers into a Windows guest, the networking fails on reboot. What is likely wrong?

B.

After install thePV drivers, the MAC address of the network interfaces must be changed in vm.cfg.

C.

After installing the PV drivers, the bridge setting in vm.cfg is lost and must be reset.

D.

The network type has not been changed from Fully Virtualized to Paravirtualized(the netfront driver is not specified in vm.cfg).

A number of high priority virtual machines require significant file system access and you are trying to decide what type of memory impact on dom0 they will have. Which two are best practices you should consider for memory use in dom0?

A.

You should always run a find command on dom0 to fill the file system buffer cache for bestperformance.

B.

You should not run a find command on dom0 as it will use up Dom0 memory and potentiallycause double buffering with virtual machines.

C.

When increasing load with additional virtual machines, you should always add more memory todom0.

D.

When increasing load with additional virtual machines, you generally wont add more memory todom0.

The server hosting the Oracle VM manager database repository has an unscheduled outage. What are the two consequences of this issue?

A.

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

B.

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

C.

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

D.

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

E.

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.

F.

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