  A. /OVS3
  B. /var/ovs/mount/root C. /var/ovs/mount/OVSROOT

• Question 24:

  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 Apps vm sd attach -n Test -d Apps
  B. sd new -d 10240 -n Apps sd reg -n Apps vm sd attach -n Test -d Apps
  C. vm disk add -n Test -d Apps -S 10240
  D. vm sd attach -n Test -d Apps -S 10240
  E. vm disk add -n Test -d Apps -S 10240 vm sd attach -n Test -d Apps
  E. vm disk add -n Test -d Apps -S 10240 vm sd attach -n Test -d Apps

• Question 25:

  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 for growth.
  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.
  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.

• Question 26:

  What clustered file system (s) are supported for storage poolthat will be shared In Oracle VM?

  A. GFS only
  B. GFS and NFS only
  C. OCFS2 only
  D. OCFS2 and GFS only
  E. GFS, OCFS2 and NFS
  F. NFS only
  E. GFS, OCFS2 and NFS

• Question 27:

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

• Question 28:

  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.
  A. You should always run a find command on dom0 to fill the file system buffer cache for bestperformance.
  C. When increasing load with additional virtual machines, you should always add more memory todom0.

• Question 29:

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

• Question 30:

  A customer decides to use 2 large servers to load balance a mix of large and small virtual machines. Each server has 64GB of RAM and 8 quad-core CPUs. There are 14 virtual machines, 6 of which use 12GB of virtual memory and 16 vCPU each, and the remaining 8 use 2GB and 4 vCPUs each. What two issues will the customer likely discover when one of the servers fails?

  A. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of vCPUs.
  B. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of memory.
  C. Live migration will be unavailable until the second server is restored.
  D. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of vNICs.
  E. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of shared storage.
  A. Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of vCPUs.
