Question 33: Amazon Elastic Compute Cloud (EC2) is primarily considered which type of cloud computing model?
A. Software as a service (SaaS)
B. Platform as a service (PaaS)
C. Infrastructure as a service (IaaS)
D. None of the above
Correct Answer: C. Infrastructure as a service (IaaS)
Explanation: AWS is a public cloud platform that provides a mix of IaaS, PaaS and SaaS, but its EC2 offering is predominately categorized as IaaS. The provider offers a range of services for compute, networking and storage, as well as a variety of different VM instance types.
Question 34: What is a public cloud?
A. A cloud formation that can be seen across the globe
B. A cloud service that can only be accessed from a publicly shared computer
C. A multi-tenant cloud environment accessed over the internet
D. A cloud environment owned, operated and controlled by a public company
Correct Answer: C. A multi-tenant cloud environment accessed over the internet
Explanation: A public cloud is a cloud deployment model in which infrastructure and application services are accessed via the internet from a third-party provider in a multi-tenant environment. Some of the top vendors in this market include AWS, Microsoft and Google.
Question 35: Which of the following statements could be used to describe a private cloud deployment?
A. A cloud environment maintained within an enterprise’s own data center
B. A private environment within a third-party or public cloud provider’s architecture
C. A cloud service inaccessible to anyone but the cultural elite
D. Both 1 and 2
Correct Answer: D. Both 1 and 2
Explanation: There are various types of private clouds, including the more traditional, on-premises private cloud, which is a dedicated environment hosted within an enterprise’s on-premises data center, as well as a hosted or virtual private cloud, which is a private cloud environment hosted by a third-party provider.
Question 36: What is a hybrid cloud?
A. A blend of public and private cloud services with orchestration between them
B. A cloud service deployed across multiple offices or locations
C. A blend of private cloud and legacy on-premises hardware
D. None of the above
Correct Answer: A. A blend of public and private cloud services with orchestration between them
Explanation: Hybrid cloud is a mix of on-premises private cloud and public cloud services, where workloads move and orchestrate between them. This deployment model enables enterprises to keep mission-critical workloads in the private environment and host nonsensitive workloads in public cloud. Hybrid cloud is also beneficial for dynamic workloads that may need to burst into the public cloud due to high demand.
Question 37: Which of these options is not a PaaS offering?
A. IBM App Mix
B. Azure App Service
C. AWS Elastic Beanstalk
D. Google App Engine
Correct Answer: A. IBM App Mix
Explanation: AWS Elastic Beanstalk, Azure App Service and Google App Engine are examples of PaaS offerings. To choose between these and other PaaS options, enterprises need to carefully evaluate their application development and deployment requirements.
Question 38: According to what’s known as the shared responsibility model in public cloud, which of the following components are cloud customers — not providers — responsible for?
A. The security and maintenance of underlying hardware, such as servers
B. The physical security of cloud data centers
C. The security of users’ data
D. The provider is responsible for all components above
Correct Answer: C. The security of users’ data
Explanation: In a shared responsibility model, users and providers have different security obligations. While the user’s level of responsibility varies based on the deployment model — IaaS vs. PaaS vs. SaaS — the user is largely responsible for the security of his or her own data. However, since there is no standard model across cloud vendors or services, enterprises need to carefully review all service-level agreements (SLAs).
Question 39: Which of the following acronyms refers to a software distribution model in which a cloud provider manages and hosts an app that users access via the internet?
A. IaaS
B. PaaS
C. SaaS
D. None of the above
Correct Answer: C. SaaS
Explanation: SaaS is a cloud computing service category in which a provider hosts an application on its own infrastructure that users can access via the internet. With SaaS, an enterprise no longer needs to install and run an application on its own hardware.
Question 40: True or false: A multi-cloud strategy is the same as hybrid cloud.
A. True
B. False
Correct Answer: B. False
Explanation: While the definition of multi-cloud has been a bit fuzzy, a multi-cloud strategy most commonly refers to the use of two or more public IaaS clouds from different vendors. Enterprises typically pursue this deployment model to take advantage of more services, optimize their costs or avoid vendor lock-in. The hybrid cloud model, by contrast, refers to a mix of private and public cloud platforms with workload orchestration between the two.
