Emily, a security architect, has developed a framework in which several authentication servers work together to increase processing power for an application. Which of the following does this represent?
A. Warm site B. Load balancing C. Clustering D. RAID
Answer: C
Explanation: Anytime you connect multiple computers to work/act together as a single server, it is known as clustering.

Server clustering is used to provide failover capabilities / redundancy in addition to scalability as demand increases.
