a) Client
b) Server
c) Cache
d) Database
Answer: c) Cache
Explanation: Caching helps in improving the scalability and performance of RESTful services by storing copies of frequently accessed data.
9. Software as a Service (SaaS) provides software applications over the internet on a subscription basis. (True/False)
Answer: True
Explanation: SaaS delivers software applications over the internet, typically on a subscription basis, eliminating the need for users to install and maintain the software locally.
10. Platform as a Service (PaaS) provides virtualized servers and infrastructure resources to users. (True/False)
Answer: False
Explanation: Platform as a Service (PaaS) provides users with a platform allowing them to develop, run, and manage applications without dealing with the infrastructure.

c) Application Programming Interface (API)
d) All of the above
Answer: d) All of the above
Explanation: Cloud services can be administered and monitored through various interfaces including CLI, GUI, and API.
13. Which of the following is not a benefit of cloud computing?
a) Cost savings
b) Scalability
c) Limited accessibility
d) Flexibility
Answer: c) Limited accessibility
Explanation: Cloud computing typically offers improved accessibility, enabling users to access resources from anywhere with an internet connection.
14. Hypervisor is a software that:
a) Monitors and manages cloud services
b) Virtualizes hardware resources
c) Provides web services
d) Implements RESTful APIs
Answer: b) Virtualizes hardware resources
Explanation: A hypervisor, also known as a virtual machine monitor, allows multiple operating systems to share a single hardware host.
15. Which of the following is not a type of cloud deployment model?
a) Public cloud
b) Private cloud
c) Hybrid cloud
d) Local cloud
Answer: d) Local cloud
Explanation: Local cloud is not a recognized deployment model in cloud computing; the typical models are public, private, and hybrid clouds.
16. Which of the following is a characteristic of Software as a Service (SaaS)?
a) Users manage the underlying infrastructure
b) Pay-per-use billing model
c) Highly customizable software
d) Requires installation and maintenance by users
Answer: b) Pay-per-use billing model
Explanation: SaaS typically operates on a pay-per-use or subscription-based billing model, where users pay for the software they use.
17. Which of the following is not a characteristic of Platform as a Service (PaaS)?
a) Provides development tools
b) Allows users to manage underlying infrastructure
c) Supports application deployment
d) Facilitates collaboration among developers
Answer: b) Allows users to manage underlying infrastructure
Explanation: PaaS abstracts away the underlying infrastructure, allowing users to focus on application development and deployment without managing the infrastructure.
