Fundamental Cloud Computing v6.0 (C90.01) Flashcards
The Increased Security Vulnerabilities challenge of cloud computing occurs when a cloud consumer organization needs to enable external communication with cloud-based IT resources. This increases vulnerabilities within the cloud consumer’s organizational boundary because attackers can penetrate the on-premise environment to compromise on- premise IT resources within the cloud consumer trust boundary. This challenge does pertain to security vulnerabilities within the cloud itself. Select the correct answer.
A. True
B. False
B. False

C. private
Which of the following scenarios describes the Reduced Investment and Proportional Costs benefit of cloud computing? Select the correct answer.
A. A cloud consumer pays a usage fee for only the amount of the IT resources actually used. This gives the cloud consumer organization access to IT resources without having to purchase its own.
B. A cloud consumer pays the expenses associated with the cost of capital in order to fund the up-front costs for the cloud provider IT resources used. This gives the cloud consumer organization the option to budget required up-front costs before committing to IT resource usage.
C. A cloud consumer avoids payment of up-front costs and usage fees for cloud provider IT resources it uses by following the cost of capital model. This allows the cloud consumer organization to obtain access to IT resources with “no money down”. This gives the cloud consumer organization the ability to begin working with cloud-based IT resources with no immediate funds, but then subjects the organization to increased costs later when high- interest rates begin to apply after a pre-defined period.
D. None of the above.
A. A cloud consumer pays a usage fee for only the amount of the IT resources actually used. This gives the cloud consumer organization access to IT resources without having to purchase its own.
