  • 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 usedin the guest

  • B. Use the repos.py command with the --new option, along with the UUID assigned to the repository.
  • C. Use the repos.py command with the--newoption, along with the UUID assigned to the repository and a device path.
  • D. Use the repos.py command with the path. root option, along with either a device path or an nfs path.

Question 4

When converting hardware virtualized machine to full PV, the guest falls to boot. What line in vm.cfq
is likely leftover from the HVM configuration?
A. vnclisten = '0.0.0.0'
B. pae =1
C. builder=hvm
D. serial=pty

Answer:

C
My suggestion is to use builder=hvm because it works fine for once I have failed to booting the
server but when I made it builder=hvm it booted fine. Another thing is if you use linux os as
amother os then you can leftover this builder=hvm but if you use windows2003 then you have to
use builder=hvm.

Question 6

When using NFS, what technology is used to control locking on the NFS mount?

  • A. Oracle VM uses the same DLM (distributed lock manager) for NFS as it does for OCFS2 partitions.
  • B. The standard NFS drivers are sufficient to properly lock files in an NFS repository.
  • C. Oracle VM ships with the IO-EMU drivers, which provide proper locking for files on an NFS repository.
  • D. Oracle VM ships with a DM-NFS server, which runs on the master pool server and handles distributed file locking for an NFS repository.

Question 9

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 forgrowth.
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.

Answer:

A
You can use the split technology to split your partitions as a 2 GB space and can define the max size
and when needed Oracle VM can automatically add the more storage there and also you can modify
the max size of the storage repository.

name of subdirectory?
A. Each repository will create mount point under /OVS, with a directory named using the UUID of the
respiratory.
B. Each repository will create a mount point under /var/ovs, In a directory named using the UUID
ofthe repository.
C. Each repository will create a mount point under /var/ovs/mount, in a directory named using
theUUID of the repository.
D. Each repository willcreate a mount point under /OVS, with a directory named using a
sequencenumber starting at 0.
E. Each repository will create a mount point under /var/ovs, with a directory named using a
sequence number starting at 0.
F. Each repository will create a mountpoint under /var/ovs/mount, with a directory named using a
sequence number starting at 0.
