A. The internal messaging system within the Xen hypervisor.

B. An extension of libvirt which adds live migration of virtual servers between arbitrary hypervisors.

C. A ReSTful API which is used by xl to communicate with the Xen hypervisor.

D. A high level tool chain which provides advanced management tools and interfaces for Xen.

E. The communication interface between a paravirtualized Linux Kernel and the Xen hypervisor.

A. Ctrl-Alt-3

B. Ctrl-Alt-2

C. Ctrl-Alt-4

D. Ctrl-Alt-1

E. Ctrl-Alt-0

A. Regular backups become generally unnecessary as any data loss or corruption is automatically recovered by the high availability cluster.

B. Regular backups remain vital as they allow restoration of data that was accidentally deleted or corrupted.

C. Backups should be located only on the local storage of the cluster and should not be backed up in order to prevent bandwidth congestion.

D. Backup procedures may have to be adapted to the cluster to ensure complete and recoverable backups.

E. Regular backups may be reduced to the cluster configuration and cluster state data as this information is sufficient to recover any state of the cluster, including data, at any time.

A. The default quorum policy in a two node cluster must be set to ignore in order to configure a working cluster.

B. In a two node cluster, quorum can be determined and handled just as in a cluster with a higher number of nodes.

C. Clusters with one or two nodes cannot have a quorum and require no quorum configuration.

D. In a two node cluster the quorum is always held by the node that first started the cluster software.

A. Define constraints on which services may run on the same cluster node.

B. Prevent failed nodes from interfering with the remaining intact part of the cluster.

C. Provide multi-tenancy cluster configuration for cloud computing.

D. Enforce storage quota and other resource limitations for each service provided by the cluster.

E. Ensure a consistent assignment of all network connections from a client to the same cluster server.

A. OCFS2 is an integral part of Pacemaker and relies on Pacemaker services for functionality.

B. OCFS2 can be used without any additional software as it contains its own cluster manager, O2CB.

C. When using OCFS2 with additional cluster software, OCFS2 must be integrated into the overall cluster manager to ensure consistent cluster behaviour.

D. In addition to filesystems, OCFS2 can handle other cluster services such as IP addresses and server daemons.

E. To avoid the need for shared storage, OCFS2 can replicate the content of its filesystems via the network.
