Your network consists of one Active Directory domain. All domain controllers run Windows Server 2008.
You need to prepare the environment to provide a high-availability solution for a back-end Microsoft SQL Server 2005 data store.
What should you do?
A. Install a Windows Server 2003 Network Load Balancing cluster.
B. Install a Windows Server 2008 Network Load Balancing cluster.
C. Install a Windows Server 2008 failover cluster that has shared storage.
D. Install a Windows Server 2008 failover cluster that has direct attached storage.
Correct Answer: C
Explanation/Reference:
Explanation:
To ensure the high availability of the data store, you need to use Windows Server 2008 failover cluster having a shared storage.
Failover clustering can help you build redundancy into your network and eliminate single points of failure.
Administrators have better control and can achieve better performance with storage than was possible in previous releases. Failover clusters now support GUID partition table (GPT) disks that can have capacities of larger than 2 terabytes, for increased disk size and robustness. Administrators can now modify resource dependencies while resources are online, which means they can make an additional disk available without interrupting access to the application that will use it. And administrators can run tools in Maintenance Mode to check, fix, back up, or restore disks more easily and with less disruption to the cluster
You should not use Network Load Balancing (NLB) because it only allows you to distribute TCP/IP requests to multiple systems in order to optimize resource utilization, decrease computing time, and ensure system availability.
