Certified Data Centre Professional (CDCP) Practice Exam

The correct answer highlights ISO/IEC 20000 as the relevant worldwide standard for IT service management and certification. This standard provides a framework for establishing, implementing, maintaining, and continually improving an IT service management system (SMS).

ISO/IEC 20000 is recognized internationally and serves as a benchmark for organizations seeking to deliver effective IT services. By adhering to this standard, organizations can demonstrate their ability to manage and improve their IT service management processes, ensuring that they meet customer needs and manage risks effectively.

While ITIL® is a well-known framework that offers best practices for managing IT services, it does not itself serve as a certification standard. Instead, organizations can achieve certification against ISO/IEC 20000 to formally validate their compliance with established criteria in IT service management. The BS15000 was an earlier standard that was eventually superseded by ISO/IEC 20000, further solidifying the latter's position as the global standard in this realm. Therefore, the emphasis is rightly placed on ISO/IEC 20000 as the globally acknowledged standard for IT service management certification.
