Which statement best describes the relationship between a data centre and business continuity?

The data centre is a cornerstone of modern business continuity and disaster recovery (BC/DR) planning. Its primary role in this context is to ensure that critical IT systems, applications, and data remain available and operational during and after a disruptive event, such as a natural disaster, power outage, or cyber-attack. This is achieved through built-in redundancy of power and cooling systems, resilient network connections, robust security, and often, the use of secondary disaster recovery data centre sites for failover. The data centre's resilience directly translates to the organization's ability to continue its core functions.

A. This is factually incorrect; data centres are central to any IT-dependent business continuity strategy.

B. Operational continuity is a foundational business requirement, generally considered more critical for immediate survival than marketing functions.

D. Data centres support all critical business applications, including but not limited to financial accounting.
