Explanation:

To deploy a failover cluster solution to service users in both offices, you need to Deploy a failover cluster that contains one node in each office head office and branch office Windows Server 2008 supports the shared-nothing cluster model, in which two or more independent servers, or nodes, share resources; each server owns and is responsible for managing its local resources and provides nonsharing services. In case of a node failure, the disks, resources and services running on the failed node fail over to a surviving node in the cluster. For example, if an Exchange server is operating on node 1 of the cluster and it crashes, the Exchange application and services will automatically fail over to node 2 of the cluster. This model minimizes server outage and downtime. Only one node manages one particular set of disks, cluster resources and services at any given time. Failover clustering, network load balancing drive high availability
