QUESTION 1
When a domain is live migrated, what resources are migrated between the source and target servers?

A. First the VM files are migrated between the servers, then the memory, then the CPU registers.
B. First the VM files are migrated between the servers, then the memory.
C. First the memory is migrated between the servers, and then the CPU registers.
D. Only memory is migrated.

Answer: A

Explanation:
live migration- is similar to warm migration, except that the guest is notsuspended during transmission. Instead, the LDoms manager keeps track of memory changed while state is being transmitted, and then makes followup passes to retransmit data changed state information. Abriefpause is used at the end to transmit residual changed state. This method is typical for virtual machine systems that provide live guest migration.

QUESTION 2
In which two of the following, disk multi pathing enabled for a block device on an Oracle VM server?

A. When local disks are added.
B. When iSCSI disks are attached.
C. When fiber channel disks are attached.
D. When a new NFS repository is added.
E. When a virtual disk is added to a guest virtual machine.

Answer: B,C

QUESTION 3

A. Oracle VM
B. Oracle VM virtual box
C. VMware player
D. Xen
E. Solaris Zone
F. VMware ESXI

Answer: A,D,F

QUESTION 4
What component of Oracle VM Product is specifically responsible for the automatic failover process?

A. OCFS2
B. Server Pool Master
C. Oracle Clusterware
D. utility server
E. virtual machine server

Answer: B
Explanation:
https://docs.oracle.com/cd/E11081_01/doc/doc.21/e10898/ha.htm
To enable HA, you must first make sure all Virtual Machine Servers in the server pool:
Use the same shared storage.
Are in the same OCFS2 or NFS cluster.
Are Oracle VM Server Release 2.1.2 or above.
Have the same cluster root, which is a specially designated shared storage used for heatbeating in the cluster. For example, the cluster root might be example.com:/OVS for an NFS cluster, or /dev/sdd6 for an OCFS2 cluster. The heartbeat file would be located at example.com:/OVS/.server_pool_hb for an NFS cluster. There is no heartbeat file for an OCFS2 cluster as one is in-built in the file system.
Have the cluster root mounted at /OVS. All other storage may be mounted at the standard location of /OVS/uuid.
Have moved any /OVS mount points (set in FSTAB for Releases 2.1 or 2.1.1) to the /etc/ovs/repositories file. All storage, even that mounted at /OVS, must be maintained in the /etc/ovs/repositories file. You can move the mount points to the /etc/ovs/repositories file with the following command: # /usr/lib/ovs/ovs-cluster-check –alter-fstab Have a shared cluster root at /OVS, and not local, using clustered OCFS2 on SAN, or ISCSI storage, or NFS on NAS. The default local storage is OCFS2, and is notsupported with HA.

QUESTION 5
Which statement is true about Oracle VM server in the server pool where a P2V converted VM machines will be deployed?

A. The server where the template is deployed should have enough local disk to store the virtual disk images.
B. The server mustbe in the clustered server pool.
C. The server must have more memory then the host that was converted.
D. The P2V converted virtual machine must have a unique name.
E. The server in the server pool must have hardware virtualized support (have intel VT-X orAMD-v chip feature).
