Your network contains a six-node Microsoft Clustering Service (MSCS) cluster that has a shared
quorum. Each of the six nodes runs Windows Server 2003. You need to recommend a solution to
transition the cluster to Windows Server 2008. The solution must maintain the availability of cluster
services during the transition. What should you recommend?
A.
Evict one node at a time and rebuild the cluster by using Windows Server 2008.
B.
Evict five nodes from the cluster. Install Windows Server 2008 on the remaining node. Add five
new Windows Server 2008 nodes.
C.
On each node, run the Windows Server 2008 installation program.
D.
On the MSCS, change the quorum type to a Majority Node Set (MNS) quorum. Install Windows
Server 2008 on all nodes.
Explanation:
To ensure a smooth transition of the cluster from Windows Server 2003 to Windows Server 2008
while maintaining the availability of the cluster services during the transition, you need to evict one
node at a time and rebuild the cluster by using Windows Server 2008. It is not important which
cluster node you upgrade first in your organization. However, you need to evict the passive node
first. For eviction, you need to stop the Cluster Service on the passive node, and then evict Node
from the server cluster.
