Q1. 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 


Q2. A customer has installed Oracle VM Manager from the Oracle-provided template onto a server pool of ten servers. As additional VMs are being added, the user interface for the Oracle VM Manager application is becoming slow. 

What is the problem? 

A. The Oracle VM Manager guest does not have the HA flag set, and is therefore not being moved to a server with sufficient capacity. 

B. The Oracle VM Manager guest is on a server that has insufficient memory. 

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. 

Answer: A 


Q3. Which three attributes of an existing virtual disk can be changed using Oracle VM Manager? 

A. Virtual Disk N 

B. Virtual Disk Size 

C. Hard Drive Type 

D. QoS Enabled 

E. Priority Class 

Answer: B,D,E 

Explanation: 

For an existing virtual disk you can change the size vmware-vdiskmanager -x 80GB mydisk.vmdk 

From the Virtuladisk Manager scrren you can change the QoS enable and disable and the Priority class you can change. 


Q4. What requirements apply to shared storage on an HA Server Pool? 

A. Each server in the pool must have a connection to the shared storage, using NFS, ISCSI or a SAN Either ext3 or OCFS2 should be used to format the shared file system. 

B. Each server in the pool must have a connection to the shared storage, using NFS, (SCSI or a SAN. Either gfs or OCFS2 should be used to format the shared file system. 

C. t least one server in the pool must have a connection to the shared storage, using iSCSI or a SAN. Either ext3 or OCFS2 should be used to format the shared file system. 

D. Each server in the pool must have a connection to the shared storage, using iSCSI or a SAN. Only OCFS2 should be used to format the shared file system when using iSCSI or a SAN. 

E. Each server in the pool must have a connection to the shared storage, using NFS, iSCSI or a SAN. Only OCFS2 should be used to format the shared file system when using iSCSI or a SAN. 

Answer: E 


Q5. 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. 

Answer: C 


Q6. 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: A,B 

Explanation: 

In the question two steps are required so that you have to answer two here. 

Oracle Clusterware Ensure that your server is going to be restarted facility and it will 

provide you the failover feature for you as well. You have to turn on HA Mode in the server 

pool. 


Q7. What two steps can be used to create a highly available storage repository? 

A. Turn on HA in the storage pool to create a redundant backup of virtual machines hosted in thatstorage pool. 

B. Use network bonding to create multiple redundant paths to an iSCSI LUN. 

C. Use multipathing to create multiple storage network paths to a SAN LUN. 

D. Use Oracle Clusterware to create multiple paths to a SAN LUN. 

E. Use Oracle Clusterware to create each storage repository on a different storage network. 

Answer: A,D 


Q8. When setting up a server pool, enabling what option will persist the IP address of a server pool master after an HA failover?
