You need to gain approval to begin moving your company's data and systems into a cloud environment. However, your CEO has mandated the ability to easily remove your IT assets from the cloud provider as a precondition.
Which of the following cloud concepts would this pertain to?
Correct Answer:
D
Reversibility is the cloud concept involving the ability for a cloud customer to remove all of its data and IT assets from a cloud provider. Also, processes and agreements would be in place with the cloud provider that ensure all removals have been completed fully within the agreed upon timeframe. Portability refers to the ability to easily move between different cloud providers and not be locked into a specific one. Removability and extraction are both provided as terms similar to reversibility, but neither is the official term or concept.

One of the main components of system audits is the ability to track changes over time and to match these changes with continued compliance and internal processes.
Which aspect of cloud computing makes this particular component more challenging than in a traditional data center?
Correct Answer:
B
Cloud services make exclusive use of virtualization, and systems change over time, including the addition, subtraction, and reimaging of virtual machines. It is extremely unlikely that the exact same virtual machines and images used in a previous audit would still be in use or even available for a later audit, making the tracking of changes over time extremely difficult, or even impossible. Elasticity refers to the ability to add and remove resources from a system or service to meet current demand, and although it plays a factor in making the tracking of virtual machines very difficult over time, it is not the best answer in this case. Resource pooling pertains to a cloud environment sharing a large amount of resources between different customers and services. Portability refers to the ability to move systems or services easily between different cloud providers.

Within an Infrastructure as a Service model, which of the following would NOT be a measured service?
Correct Answer:
C
Within IaaS, the number of users on a system is not relevant to the particular hosting model in regard to cloud resources. IaaS is focused on infrastructure needs of a system or application. Therefore, a factor such as the number of users that could affect licensing requirements, for example, would apply to the SaaS model, or in some instances to PaaS.
