Clustering and Rolling Upgrades (Exam 70-642)
Question: Performing a rolling upgrade from a Windows 2003 failover cluster to Windows 2008 can be accomplished using which method?
- Windows 2008 does not support failover clustering.
- There is no failover cluster upgrade path possible from Windows 2003 to Windows 2008.
- Create a failover cluster running Windows 2008 and use the wizard to migrate resources.
- Upgrade node 1 and then node 2 to Windows 2008
C. Windows 2008 supports the migration of certain failover cluster resources from Windows 2003 with the included wizard.
Answer B is mostly correct; however, the question of performing a "rolling upgrade" is tricky. A rolling upgrade implies an upgrade of each node's operating system image, and that feature is not supported.
Windows Server 2008 Enterprise Edition is required for the role Failover Cluster.
Tip: Both the cluster servers' hardware and software should be identical for optimum success.
