You are an Enterprise administrator for TestKing.com. The company has a head office and a branch office that connect with each other by using WAN links. The corporate network of the company consists of a single Active Directory domain and an Active Directory site exists for each office.
All the servers in the domain run Windows Server 2008 Enterprise Edition and all client computers run Windows Vista.
You have been assigned the task to deploy a failover cluster solution to service users in both offices. The cluster must maintain the availability of services using minimum number of servers when a single server fails.
Which of the following options would you choose to accomplish the desired task?
A.
Deploy a failover cluster that contains two nodes in each office, head office and branch office.
B.
Deploy a failover cluster that contains two nodes in the head office.
C.
Deploy a failover cluster that contains one node in the head office.
D.
Deploy a failover cluster that contains one node in each office head office and branch office.
E.
None of the above
Explanation:
To deploy a failover cluster solution to service users in both offices and maintain the availability of services using minimum number of servers when a single server fails, 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.
