CompTIA Security Plus Mock Test Q412

Sara, 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

Correct Answer: C
Section: Compliance and Operational Security

Anytime you connect multiple computers to work/act together as a single server, it is known as clustering. Clustered systems utilize parallel processing (improving performance and availability) and add redundancy.
Server clustering is used to provide failover capabilities / redundancy in addition to scalability as demand increases.
Incorrect Answers:
A: A warm site is part of disaster recovery and involves he provision of some of the capabilities of a hot site, but it requires the customer to do more work to become operational. Warm sites provide computer systems and compatible media capabilities.
B: Load balancing is a way of providing high availability by splitting the workload across multiple computers.
D: RAID, or redundant array of independent disks (RAID). RAID allows your existing servers to have more than one hard drive so that if the main hard drive fails, the system keeps functioning.
