• Question 53:

  Which of the following situations can result in a split brain situation in a high availability cluster?

  A. The load balancer of a load balanced cluster fails.

  B. The communication between the cluster nodes is interrupted.

  C. Cluster services are moved between cluster nodes.

  D. More than one node is active in a load balanced cluster.

  E. A cluster node has successfully been fenced.

  Correct Answer: B

• Question 54:

  Which of the following statements describes fencing resources in a high availability cluster?

  A. Fencing is the automated stop and restart of cluster services that suffer from software errors.

  B. Fencing is the disconnection of a failed cluster node from any other cluster resources.

  C. Fencing is the forwarding of incoming network connections to backend servers.

  D. Fencing is the assignment of services to different cluster nodes to avoid interference of the services.

  E. Fencing is the accounting and limitation of disk usage on shared storage.

  Correct Answer: B

• Question 55:

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

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

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

  Correct Answer: BE

• Question 56:

  Which of the following statements are true regarding a load balancer? (Choose TWO correct answers.)

  A. Failover clusters are not operational without at least one dedicated load balancer.

  B. All response packages sent from a backend server to a client must pass through the load balancer.

  C. The load balancer is usually deployed on one of the backend servers.

  D. Load balancers may be able to analyze traffic.

  E. All incoming connections to the cluster services are received by the load balancer.

  Correct Answer: DE

• Question 57:

  Which of the following statements is true regarding a failover cluster?

  A. The core component of every failover cluster is a load balancer.

  B. Every service may not be run more than once in a cluster.

  C. Failover clusters provide scalability of a service beyond the capacities of one cluster node.

  D. Failover clusters always require storage that is shared by all nodes.

  E. In normal operation, services may be spread over all nodes.

  Correct Answer: E
