Question 1:
What is the effect of running a server pool restores?
A. When you restore a server pool, all the data stored in the Oracle VM Manager database Isdeleted, and the data in the server pool master and virtual machine servers is used to restock the database.
B. When you restore a server pool, all servers are removed from the pool, and the data in the database is removed, restoring the server pool to its initial state.
C. When you restore a server pool, all the data stored in the server pool master will be deleted, and will be synchronized with the latest information from the Oracle VM Manager database. The server pool master is responsible for updating the individual Oracle VM servers\’ agent databases.
D. When you restore a server pool, a signal is sent out to each server in the pool, which responds with the current state of all of the virtual machines it hosts. This data is used to restore the data in the Oracle VM database.
Correct Answer: C
Question 2:

A. The virtual machine was not exported properly using the Oracle VM Manager.
B. The virtual machine configuration file needs to be changed to update the new paths to its virtualdisks.
C. The virtual machine configuration file lists bridges that do not exist on the new host.

Correct Answer: AD
Question 3:
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.
Correct Answer: A
Question 4:
What task can an Administrator do that a Manager cannot in Oracle VM Manager?
A. manage server pools
B. manage servers
C. manage resources
D. manage virtual machines
E. create users and groups
F. import resources
Correct Answer: E
Oracle VM Manager can manages the server pools, resources, virtual machines and also it can import resources but it cannot create the users and groups.
Question 5:
During installation of Oracle VM Manager to a new Oracle Enterprise Linux server, the installer fails with a message indicating that there is insufficient swap space.
What is the cause for this error?
A. The installer has determined that the Oracle application server\’s (OC4J) minimum requirement for swap space has not been met.
B. The installer has determined that the Oracle Database XE server\’s minimum requirement for swap space has not been met.
C. The installer has determined that there is insufficient swap space to unpack the installer into the /var subdirectory.
D. The installer has determined that the swap space recognized by the system has been incorrectly formatted to use TMPFS instead of SWAPFS.
Correct Answer: B
Question 6:
In a paravirtualized environment, which answer best describes the drivers that are used in domO and the guest to communicate network I/O requests?
A. A netback driver is used in dom0, and a netfront driver is used in the guest.
B. A native device driver is used in dom0, and a netback driver is used in the guest.
C. A netfront driver is used in dom0, and a native device driver is used in the guest.
D. A netfront driver is used in dom0, and a blkbck driver is used in the guest.
E. Native drivers are used in both dom0 and the guest.

Question 7:
When vitalizing a cluster of Windows 2003 servers on Oracle VM, which virtualization technique should be used?
A. Use PV with Microsoft\’s Windows 2003 64-bit with a paravirtualized kernel
B. Use HVM with a standard distribution of Windows 2003 and PV drivers.
C. Use emulation with the IOEMU drivers for better I/O performance.
D. Oracle VM does not support Windows 2003 Server. Use VirtualBox instead.
E. Oracle VM does not support Windows 2003 Server. Use Containers instead.
Correct Answer: B
I told you before about the HVM for Windows 2003
