2 D. OCFS2 and GFS only E. GFS, OCFS2 and NFS F. NFS only Answer: E QUESTION: 70 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. In Oracle VM Manager, set the maximum number of CPUs to 4. B. Use the xm vcpu-pin command on the domain once it 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. Use the xm vcpu-set command before the domain is up and running, using 4 for the CPUs parameter. E. Modify the vcpus line in vm.cfg to read: vcpus=4. Answer: E QUESTION: 71 As you are grouping workloads into server pools, you decide you want to use network traffic as one of your criteria. Which answer describes how Network QoS (Quality of Service) might apply? A. throttles (restricts) the inbound and outbound network traffic for a virtual machine vif B. throttles (restricts) the inbound and outbound network traffic for a physical network interface C. throttles (unrestricts) the inbound and outbound network traffic for a virtual machine vif D. throttles (unrestricts) the inbound and outbound network traffic for a physical network interface E. is not yet available with Oracle VM 2.2 but will be added in a subsequent release QUESTION: 72 In an emulated/translated environment with ten guests, each operating at looohz clock rate, how many interrupts will be created per second? 25

3 A. 1 B. 100 C. 1,000 D. 10,000 E. 100,000 QUESTION: 73 In which directory should an Oracle VM guest be placed In order to Import It as a virtual machine? A. running_pool B. publlsh_pool C. seed_pool D. iso_pool E. shareddisk QUESTION: 74 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. QUESTION: 75 26

4 What two steps are required to ensure that virtual machines failover to a new server when their current server goes down? A. Ensure that the Oracle VM Manager is always available by installing Oracle Clusterware. B. Turn on High Availability Mode in the server pool. C. Assign a virtual IP address to the server pool. D. Turn on HA in all virtual machines that will be restarted. E. Ensure all servers in the pool have identical CPU and memory. Answer: B QUESTION: 76 A virtual machine is needed once per week to run reports, but the rest of the time it Is idling. What method will unallocate resources such as CPU and memory, while keeping the virtual machine intact and ready for rapid re-deployment? A. Pause the virtual machine when not in use, then unpause it when needed. B. Suspend the virtual machine when not in use, then resume it when needed. C. Live migrate the virtual machine to a spare server when not in use, then live migrate it back when needed. D. Power off the virtual machine when not in use, then power it back up when needed. QUESTION: 77 Intel and AMD are adding functionality to their microprocessors to improve performance of virtualized environments. Which type of virtualization MOST benefits from these technologies? A. Emulation-based technologies B. Paravirtualization C. Hardware Virtualization D. Hardware Partitioning E. Operating System Partitioning Answer: B QUESTION: 78 27

5 A customer is setting up a 32-node Oracle VM server farm. What step will best help load balance the high number of I/O requests for new virtual machines and shared disks? A. Increase the number of Oracle VM Manager instances. B. Increase the number of servers with the Server Pool Master role. C. Increase the number of servers with the Utility Server role. D. Increase the number of servers with the Virtual Machine Server role. QUESTION: 79 Which two are true of an NFS repository when used with Oracle VM? A. NFS repositories are excellent for storing guests' root file systems. B. NFS is a more expensive option than iscsi or SAN fabrics. C. OCFS2 must be used as the filesystem format for volumes exposed through NFS. D. NFS shares mounted directly in a guest require the DM-NFS driver to be installed on the guest. E. NFS is supported for use in RAC only when mounted from the guest (not domo). QUESTION: 80 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 swith the current state of all of the virtual machines it hosts. This data is used to restore the data in the Oracle VM database. 28
