In which scenario is a CSP considered the provider of alternative facilities?

The scenario where the cloud is used as a Business Continuity and Disaster Recovery (BCDR) option in conjunction with on-premises infrastructure is significant. In this context, the cloud service provider (CSP) is considered to be providing alternative facilities because it serves as a secondary option for resources and services that can be utilized in case of a disruption to the on-premises systems.

By leveraging cloud resources alongside on-premises infrastructure, organizations can ensure that they have adequate backup and recovery solutions in place. This setup allows them to maintain continuous operations even if their primary data center experiences an outage or disaster. The cloud acts as an alternative facility that can provide capabilities such as data storage, computing resources, and applications that can be quickly accessed when needed.

In the other scenarios provided, the focus is not on the combination of on-premises and cloud solutions as means to support alternative facilities within a BCDR strategy. Options that imply that cloud alone is used without any on-premises interplay do not meet the criteria to be considered as providing alternative facilities. This is why the choice of using the cloud as a BCDR strategy while simultaneously having an on-premises component is the appropriate response.
