Question 11

When an Oracle VM server starts, by default how does it map physical NICs to Xen bridges?

  1. Each physical NIC is mapped to one or more virtual networks, each of which is assigned a Xen bridge.
  2. One Xen bridge will be created for each physical NIC.
  3. All physical NICs are mapped to a single Xen bridge.
  4. No mapping of physical NICs to Xen bridges is done by default.
  5. The first physical NIC is assigned to dom0's management; a Xen bridge is then created for each of the remaining cards.

Question 12

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

  1. QEMU emulation is used in dom0, and a blkfront driver is used in the guest.
  2. A native device driver is used in dom0, and QEMU emulation is used in the guest.
  3. A blkfront driver is used in dom0, and a blkback driver is used in the guest
  4. QEMU emulation is used in dom0, and a native device driver is used in the guest.
  5. Native drivers are used in both dom0, and the guest.

Question 13

What two steps are required to create a root repository in an Oracle VM server pool?

  1. Use the repos.py command with the --new option, along with either a device path or an nfs path.
  2. Use the repos.py command with the --new option, along with the UUID assigned to the repository.
  3. Use the repos.py command with the--new option, along with the UUID assigned to the repository and a device path.
  4. Use the repos.py command with the path. —root option, along with either a device path or an nfs path.
  5. Use the repos.py command with the--root option, along with the UUID assigned to the repository.

Question 14

  2. pae =1
  3. builder=’hvm’
  4. serial=’pty’

Question 15

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

  2. A native device driver is used in dom0, and QEMU emulation is used in the guest.
  3. A netfront driver is used in dom0, and a netback driver is used in the guest.
  4. QEMU emulation is used in dom0, and a native device driver is used in the guest.
