質問 3

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

（B）One Xen bridge will be created for each physical NIC.

（C）All physical NICs are mapped to a single Xen bridge.

質問 5

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

（A）Oracle VM ships with the IO-EMU drivers, which provide proper locking for files on an
NFS repository.

（B）Oracle VM uses the same DLM (distributed lock manager) for NFS as it does for OCFS2 partitions.

（C）Oracle VM ships with a DM-NFS server, which runs on the master pool server and handles distributed file locking for an NFS repository.

（D）The standard NFS drivers are sufficient to properly lock files in an NFS repository.

（B）The virtual machine relies onemulation of the hardware in dom0 for block I/O.

（C）The virtual machine I/O path only uses the block device driver from dom0.

（D）The virtual machine must provide emulation of the hardware through its own IOEMU drivers.

（E）The virtual machine does not need a block device driver.

質問 7

A customer wants to use hard partitioning with Oracle VM to restrict the number of cores that can be used by a virtual machine to four cores.
Which method will best accomplish that goal?

（A）Use the xm vcpu-pin command on the domain once it is up and running, using 4 for the
CPUs parameter.

（B）Use the xm vcpu-set command before the domain is up and running, using 4 for the
CPUs parameter.

（C）Modify the cpus line in vm.cfg to set the cpus to 0-3.

（D）Modify the vcpus line in vm.cfg to read: vcpus=4.

（E）In Oracle VM Manager, set the maximum number of CPUs to 4.
