Which of the following is not a standard or regulation but a mechanism to achieve Business Continuity and Disaster Recovery (BCDR) capabilities using public cloud services?

The selection of Disaster Recovery as a Service (DRaaS) as the correct answer highlights its nature as a service model rather than a formal regulation or standard. DRaaS is specifically designed to provide organizations with the tools and services necessary to ensure business continuity and recover from disasters by leveraging the capabilities of public cloud services. It enables organizations to replicate and host physical or virtual servers in the cloud to maintain availability and restore operations swiftly following an interruption.

In contrast, SOX, GLBA, and FFIEC are all regulatory frameworks aimed at ensuring financial and operational compliance within organizations. These regulations impose requirements on how organizations manage financial data and conduct business activities but do not provide specific methodologies or services for implementing disaster recovery or business continuity directly. Instead, they may influence how organizations develop their BCDR strategies, but they do not serve as mechanisms or services themselves. Thus, the distinction lies in DRaaS being an actionable solution aimed at operational resilience, while the others are prescriptive requirements without direct implementation methods for continuity planning.
