Candidates should be able to perform the tasks listed below:

• Configure a high-availability cluster, using either physical or virtual systems, that:
  • Utilizes shared storage.
  • Provides service fail-over between the cluster nodes.
  • Provides preferred node for a given service.
  • Selectively fails over services based on specific constraints.
  • Preemptively removes non-functioning cluster members to prevent corruption of shared storage.
• Manage logical volumes in a clustered environment:
  • Create volume groups that are available to all members of a highly available cluster.
  • Create logical volumes that can be simultaneously mounted by all members of a high-availability cluster.
• Configure a GFS file system to meet specified size, layout, and performance objectives.
• Configure iSCSI initiators.
• Use multipathed devices.
• Configure cluster logging.
• Configure cluster monitoring.

As with all Red Hat performance-based exams, configurations must persist after reboot without intervention.
