Question #1

How does high availability clustering relate to periodic storage backup? (Choose TWO correct answers.)

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

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

C. 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.

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

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

Question #4

Which actions should be taken in a load balanced cluster in order to protect the load balancer against outages?

A. Two load balancers should be deployed as a failover cluster.

B. Load balancers cannot be protected against outages which is why they should always be built on dedicated hardware.

C. Load balancers are used for performance and scalability reasons only and cannot be used to archive high availability clusters.

D. No actions are necessary as a load balancer cannot become a single point of failure.

E. Two or more load balancers should be deployed as a cascade that passes packets from one to the other.

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

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

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