C. The Oracle VM Manager guest is on a server that has insufficient CPU capability.

D. The Oracle VM Manager guest has been put in maintenance mode by the Administrator.

E. The Oracle VM Manager guest is located on a master pool server, which is consuming a large portion of the I/O and processing of the server.

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 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.

Which option describes the purpose of the Generic Desktop Provider?

A. It connects to a pool of virtual machines with a RDP service.
