Correct Answer: D
Question 22
In all three cloud deployment models, (laaS, PaaS, and SaaS), who is responsible for the patching of the hypervisor layer?
Correct Answer: A
The cloud service provider is responsible for the patching of the hypervisor layer in all three cloud deployment models (IaaS, PaaS, and SaaS). The hypervisor layer is the software that allows the creation and management of virtual machines on a physical server. The hypervisor layer is part of the cloud infrastructure, which is owned and operated by the cloud service provider. The cloud service provider is responsible for ensuring that the hypervisor layer is secure, reliable, and up to date with the latest patches and updates. The cloud service provider should also monitor and report on the status and performance of the hypervisor layer, as well as any issues or incidents that may affect it. The cloud service customer is not responsible for the patching of the hypervisor layer, as they do not have access or control over the cloud infrastructure. The cloud service customer only has access and control over the cloud resources and services that they consume from the cloud service provider, such as virtual machines, storage, databases, applications, etc. The cloud service customer is responsible for ensuring that their own cloud resources and services are secure, compliant, and updated with the latest patches and updates. The patching of the hypervisor layer is not a shared responsibility between the cloud service provider and the cloud service customer, as it is solely under the domain of the cloud service provider. The shared responsibility model in cloud computing refers to the division of security and compliance responsibilities between the cloud service provider and the cloud service customer, depending on the type of cloud deployment model. For example, in IaaS, the cloud service provider is responsible for securing the physical infrastructure, network, and hypervisor layer, while the cloud service customer is responsible for securing their own operating systems, applications, data, etc. In PaaS, the cloud service provider is responsible for securing everything up to the platform layer, while the cloud service customer is responsible for securing their own applications and data. In SaaS, the cloud service provider is responsible for securing everything up to the application layer, while the cloud service customer is responsible for securing their own data and user access. Patching on hypervisor layer is required, as it is essential for maintaining the security, reliability, and performance of the cloud infrastructure. Patching on hypervisor layer can help prevent vulnerabilities, bugs, errors, or exploits that may compromise or affect the functionality of the virtual machines or other cloud resources and services. Patching on hypervisor layer can also help improve or enhance the features or capabilities of the hypervisor software or hardware.

Question 23
The BEST method to report continuous assessment of a cloud provider's services to the Cloud Security Alliance (CSA) is through:
Correct Answer: D
The best method to report continuous assessment of a cloud provider's services to the Cloud Security Alliance (CSA) is through a set of dedicated application programming interfaces (APIs). According to the CSA website1, the STAR Continuous program is a component of the STAR certification that allows cloud service providers to validate their security posture on an ongoing basis. The STAR Continuous program leverages a set of APIs that can integrate with the cloud provider's existing tools and processes, such as security information and event management (SIEM), governance, risk management, and compliance (GRC), or continuous monitoring systems. The APIs enable the cloud provider to collect, analyze, and report security-related data to the CSA STAR registry in near real-time. The APIs also allow the CSA to verify the data and provide feedback to the cloud provider and the customers. The STAR Continuous program aims to provide more transparency, assurance, and trust in the cloud ecosystem by enabling continuous visibility into the security performance of cloud services. The other methods listed are not suitable for reporting continuous assessment of a cloud provider's services to the CSA. The Cloud Controls Matrix (CCM) assessment by a third-party auditor on a periodic basis is part of the STAR Certification Level 2 program, which provides a point-in-time validation of the cloud provider's security controls. However, this method does not provide continuous assessment or reporting, as it only occurs once every 12 or 24 months2. The tools selected by the third-party auditor may vary depending on the scope, criteria, and methodology of the audit, and they may not be compatible or consistent with the CSA's standards and frameworks. Moreover, the tools may not be able to report the audit results to the CSA STAR registry automatically or frequently. The SOC 2 Type 2 attestation is an independent audit report that evaluates the cloud provider's security controls based on the American Institute of Certified Public Accountants (AICPA) Trust Services Criteria. However, this report is not specific to cloud computing and does not cover all aspects of the CCM. Furthermore, this report is not intended to be shared publicly or reported to the CSA STAR registry3.

Question 24
Organizations maintain mappings between the different control frameworks they adopt to:
Correct Answer: B
Organizations maintain mappings between the different control frameworks they adopt to avoid duplication of work when assessing compliance. This is because different control frameworks may have overlapping or equivalent controls that address the same objectives or risks. By mapping these controls, organizations can streamline their compliance assessment process and reduce the cost and effort involved. Mappings also help organizations to identify any gaps or inconsistencies in their control coverage and address them accordingly. This is part of the Cloud Control Matrix (CCM) domain COM-03: Control Frameworks, which states that "The organization should identify and adopt applicable control frameworks, standards, and best practices to support the cloud compliance program."1 References := CCAK Study Guide, Chapter 3: Cloud Compliance Program, page 54
Question 25
Your company is purchasing an application from a vendor. They do not allow you to perform an on-site audit on their information system. However, they say, they will provide the third-party audit attestation on the adequate control design within their environment. Which report is the vendor providing you?
