The FIPS 140-2 standard pertains to the certification of cryptographic modules and is not a regulatory framework. The Payment Card Industry Data Security Standard (PCI DSS), the Federal Risk and Authorization Management Program (FedRAMP), and the Health Insurance Portability and Accountability Act (HIPAA) are all regulatory frameworks for sensitive or specialized data.

Federation is not a component of access control. Instead, it is used to allow users possessing credentials from other authorities and systems to access services outside of their domain. This allows for access and trust without the need to create additional, local credentials. Access control encompasses not only the key concepts of authorization and authentication, but also accounting. Accounting consists of collecting and maintaining logs for both authentication and authorization for operational and regulatory requirements.

Explanation
The cloud service developer is responsible for developing and creating cloud components and services, as well as for testing and validating services.

Explanation:
Data owner is a management role that's responsible for all aspects of how data is used and protected. The database administrator, data custodian, and data processor are all technical roles that involve the actual use and consumption of data, or the implementation of security controls and policies with the data.

Explanation
Platform as a Service would allow software developers to quickly and easily deploy their applications among different hosting providers for testing and validation in order to determine the best option. Although IaaS would also be appropriate for hosting applications, it would require too much configuration of application servers and libraries in order to test code. Conversely, PaaS would provide a ready-to-use environment from the onset. DaaS would not be appropriate in any way for software developers to use to deploy applications.
IaaS would not be appropriate in this scenario because it would require the developers to also deploy and maintain the operating system images or to contract with another firm to do so. SaaS, being a fully functional software platform, would not be appropriate for deploying applications into.
