Question 18. Which of the following best describes the "measured service" characteristic of cloud computing?

Question 19. A company currently spends $500,000 per year on physical servers that run at 15% average usage. By migrating to AWS, they would pay only for the compute they actually use. Which advantage of cloud computing does this illustrate?

Question 33. Which of the following is NOT one of the six advantages of cloud computing as described by AWS?

Question 34. True or False: AWS Elastic Beanstalk is an example of a Platform as a Service (PaaS) offering because it handles capacity provisioning, load balancing, and auto-scaling while you manage only your application code.

Question 35. An Availability Zone consists of one or more discrete data centers. What do these data centers have that provides fault isolation?

Question 40. True or False: The "broad network access" characteristic of cloud computing means that cloud resources can only be accessed from within the provider's data center network.

Question 41. A company currently runs its own data center. They spend significant time and money on hardware procurement, facility maintenance, and capacity planning. Which advantage of cloud computing directly addresses the burden of maintaining physical infrastructure?

Question 42. Which of the following is an example of a Software as a Service (SaaS) offering?

Question 43. A developer needs to quickly test a new application idea. In an on-premises environment, procuring hardware would take weeks. In the cloud, the developer can launch resources in minutes. Which advantage of cloud computing does this describe?
