Your Company has one main office and one branch office. An Active Directory site exists for each
office. The offices are connected across a wide area network (WAN) link. Servers in both offices run
Windows Server 2008 R2. You need to plan a failover clustering solution for servers that run
Microsoft SQL Server 2008. The solution must meet the following requirements:
Withstand the failure of any single cluster node.
Minimize the number of servers required to implement failover clustering.
What should you include in your plan?
A.
Deploy one single cluster that contains one cluster node on each site.
B.
Deploy one single cluster that contains two cluster nodes on each site.
C.
Deploy two separate clusters that contain one cluster node on each site.
D.
Deploy two separate clusters that contain two cluster nodes on each site.
Explanation:
To implement a failover clustering solution for servers that run Microsoft SQL Server 2005 using the
minimum number of servers and to make sure that the cluster services are available in the event of a
failure of any single cluster node, you need to install one single cluster that contains one cluster
node on each site. When a cluster span across multiple sites, it is called Geographically dispersed
cluster. Geographically dispersed clusters can form an important component in disaster preparation
and recovery. In contrast to cold standby servers, the servers in a multi-site cluster provide
automatic failover. This reduces the total service downtime in the case of a loss of a business-critical
server and requires minimum number of servers.http://209.85.175.104/search?q=cache:xX3fqAnAueoJ:download.microsoft.com/download/3/B/5/3
