Which term describes a resiliency mechanism where processing and data storage resources are replicated between physically distant sites?

• A. clustering
• B. Geographic dispersion
• C. failover
• D. power distribution unit (PDU)

Answer: (B)

This focuses on protecting operations by spreading processing and data storage across remote locations so a disaster at one site doesn’t bring everything down. Replicating compute and storage between physically distant sites creates geographic dispersion, enabling continuity of service or rapid recovery when a site fails. Clustering usually means multiple servers working together within a single location, sharing load—not necessarily across distant sites. Failover is the switching process to a standby system, which can occur within the same site or across sites, but it doesn’t inherently describe replication across remote locations. A power distribution unit is related to electrical power management and not to resiliency architecture.
