Which two statements describe the business value of data centres?

The business value of data centres stems from their role as the central nervous system of an organization's IT operations. They enable the delivery of all IT services, from internal applications to customer-facing websites (A). They are also fundamental to data protection through security measures, backups, and disaster recovery capabilities (A). Furthermore, data centres are designed and operated to meet specific regulatory and industry compliance standards (e.g., HIPAA, PCI DSS), mitigating legal and financial risks. Their inherent redundancy and resilience ensure operational continuity, allowing the business to function even during adverse events (B).

C. They only serve as storage locations: This is a gross oversimplification. Data centres are active hubs for computing and networking, not just passive storage facilities.

D. They reduce IT agility: A modern, well-architected data centre, particularly one using virtualization and automation, is a primary driver for increasing IT agility.
