Explanation
Business continuity and disaster recovery (BCDR) solutions largely sit idle until they are actually needed. This traditionally has led to increased costs for an organization because physical hardware must be purchased and operational but is not used. By using a cloud system, an organization will only pay for systems when they are being used and only for the duration of use, thus eliminating the need for extra hardware and costs. Portability is the ability to easily move services among different cloud providers. Broad network access allows access to users and staff from anywhere and from different clients, and although this would be important for a BCDR situation, it is not the best answer in this case. On-demand self-service allows users to provision services automatically and when needed, and although this too would be important for BCDR situations, it is not the best answer because it does not address costs or the biggest benefits to an organization.

Regardless of which cloud-hosting model is used, the cloud customer always has sole responsibility for the data and its security.

Explanation:
The jurisdictions where data is being stored, processed, or consumed are the ones that dictate the regulatory frameworks and compliance requirements, regardless of who the data owner or custodian might be. The other concepts for protecting data would all play a prominent role in regulatory compliance with a move to the cloud environment. Each concept needs to be evaluated based on the new configurations as well as any potential changes in jurisdiction or requirements introduced with the move to a cloud.

Explanation
A cloud customer utilizing proprietary APIs or services from one cloud provider that are unlikely to be available from another cloud provider will most negatively impact portability.
