Exam Highlights


Before taking the exam, review the key points and terms that are presented in this chapter. Return to the lessons for additional practice.

Key Points

  • Use static IP addressing for cluster network adapters. This prevents DHCP from being a point of failure.

  • Cluster nodes brought back online do not fail back unless a fail back policy is configured.

  • Network Load Balancing cannot monitor application services.

  • The Cluster Service cannot load balance.

  • Exchange Server 2003 supports only two-node active/active clusters.

Key Terms

cluster group A cluster group is a collection of cluster resources and is used to define the settings that make up a virtual server on a cluster. When a failover occurs on a node of the cluster, it is the cluster group that fails over to another node.

cluster resource A cluster resource is an individual component of a cluster virtual server, such as an IP address, a network name, or a physical disk. Cluster resources are collected into groups. When a resource fails, it restarts according to a configurable policy. If a resource exceeds its restart threshold, it can force a failover of the entire group it belongs to.

virtual server A virtual server is a configured server resource that exists through a set of software resources and settings. A virtual server is a way of mapping a collection of services and resources to physical resources and having them appear to client computers as distinct physical servers.

quorum disk The Cluster Service uses a quorum disk to maintain the master copy of the configuration data for all server nodes in a cluster. The quorum disk in a multi-node cluster must be on a shared disk resource accessible by all members of the cluster.

node A server that is a member of a cluster.
