Many large E-Business sites utilize databases on the backend of their Web site.
What technique or technology allows the highest uptime of your database servers?

A.
Using a highly normalized database structure.

B.
Clustering database servers.

C.
Analyzing database queries.

D.
Allowing concurrent database connections.

Explanation:
Web servers can operate in groups of interdependent servers, known as Web servers clusters.
Clustering allows multiple application servers toaccess the Web site database, providing faster
service to more clients by balancing requests across the cluster (load balancing). Using the
clustering technology, you can add more servers as your organization grows.
Furthermore, if one server in the cluster fails, the cluster would still be functional.
