Prerequisites

Red Hat encourages all candidates for the Red Hat Certified Specialist in High Availability Clustering exam (EX436) to consider taking the Red Hat High Availability Clustering (RH436) training course. Attendance in this class is not required, so one can choose to take just the exam. Many successful candidates who have come to class already possessing substantial skills and knowledge have reported that the class made a positive difference for them.

While attending Red Hat courses can be an important part of one's preparation to take exams, attending courses does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.

Many books and other resources on system administration for Red Hat's products are available. Red Hat does not officially endorse any as preparation guides for its exam. Nevertheless, you may find additional reading deepens understanding and can prove helpful.

  • Understand that real-world system administration experience is also an important aspect of preparation for the exam.
  • Review exam objectives for the Red Hat Certified Specialist in High Availability Clustering exam.

Course Objectives

You should be able to perform the following tasks:

Configure a high-availability cluster, using either physical or virtual systems, that:

  • Provides a service fail-over between the nodes
  • Provides a preferred node for the service
  • Selectively fails over based on node characteristics

Manage logical volumes in a clustered environment such as:

  • Create volumes and volume groups that are available to all members of a highly-available cluster
  • Create snapshots of logical volumes

Configure a GFS file system to:

  • Meet specified size, layout, and performance objectives
  • Support file system quotas

Configure iSCSI targets and initiators

Manage device configuration using udev

Create and manage Red Hat Storage based clusters including:

    • 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.
