Which term refers to a load balancing setup where a group of servers work together as a unit to provide network services?

• A. failover
• B. clustering
• C. Geographic dispersion
• D. uninterruptible power supply (UPS)

Answer: (B)

Grouping multiple servers to act as a single system that provides network services is called clustering. In a cluster, the servers coordinate to share load, provide redundancy, and present a unified service face to clients. This setup allows the system to scale by adding more nodes and to continue serving requests even if individual servers fail, depending on how the cluster is configured. Failover focuses on switching service to a backup node when the primary node fails, but it doesn’t inherently describe a group operating together as one unit to balance and manage load across multiple servers. Geographic dispersion means distributing components across different physical locations for resilience, which is about location strategy rather than the specific concept of servers acting as a coordinated unit. A UPS is about protecting power supply and is unrelated to how servers provide network services.
