You are an Enterprise administrator for contoso.com. The corporate network of the company consists of a single Active Directory domain. All the servers in the domain run Windows Server 2008 and use internal storage only and all client computers run Windows Vista.
You have been assigned the task to deploy a six node cluster on the network. You need to ensure that the cluster services are available even if two nodes of the cluster fail.
Which of the following features would you deploy to accomplish the desired task?

A.
Terminal Services RemoteApp (TS RemoteApp)

B.
Failover cluster that uses Node and File Share Disk Majority

C.
Distributed File System (DFS) that uses replication

D.
Failover cluster that uses No Majority: Disk Only

E.
None of the above

Explanation:

To ensure that the cluster services are available even if three nodes of the cluster fail, you need to deploy a failover cluster that uses Node and File Share Disk Majority.
The quorum configuration in a failover cluster determines the number of failures that the cluster can sustain. If an additional failure occurs, the cluster must stop running. The relevant failures in this context are failures of nodes or, in some cases, of a witness disk (which contains a copy of the cluster configuration) or witness file share. It is essential that the cluster stop running if too many failures occur or if there is a problem with communication between the cluster nodes.
Node and Disk Majority is (recommended for clusters with an even number of nodes) Can sustain failures of half the nodes (rounding up) if the witness disk remains online and can sustain failures of half the nodes (rounding up) minus one if the witness disk goes offline or fails. For example, a six node cluster with a failed witness disk could sustain two (3-1=2) node failures.
