Which of the following would be the GREATEST governance challenge to an organization where production...

The greatest governance challenge in the scenario where production is hosted in a public cloud and backups are held on-premises is aligning the shared responsibilities between the provider and the customer. This is because the division of security and compliance duties must be clearly understood and managed to ensure that all aspects of the cloud services are adequately protected and meet regulatory requirements. The customer is responsible for the security ‘in’ the cloud (i.e., the data and applications), while the provider is responsible for the security ‘of’ the cloud (i.e., the infrastructure). Misalignment in this shared responsibility model can lead to gaps in security and compliance, making it a significant governance challenge.
