Which of the following are the likely reasons for the clustering?

You are responsible for a Microsoft based network. Your servers are all clustered. Which of the
following are the likely reasons for the clustering?
Each correct answer represents a complete solution. Choose two.

A.
Reduce power consumption

B.
Ease of maintenance

C.
Failover

D.
Load balancing

Explanation:
Clustering provides two advantages. The first is failover. Should one server fail, the
second in the cluster can continue working with no
interruption in service to customers. This is particularly important with database servers. If one fails,
in a clustered environment the customer
will not even know the main database server is down.
Clustering also provides load balancing. This is critical for Web servers in high volume e-commerce
situations. Clustering allows the load to be
distributed over many computers rather than focused on a single server.
