1. Which of the following is an essential characteristic of Cloud Computing?
A. Scalability
B. Limited access
C. Hardware dependency
D. High cost
Answer: a) Scalability
Rationale: Cloud computing enables on-demand resources that can be scaled up or
down based on user requirements. This scalability is a core characteristic of cloud
services.
2. What is the primary function of an IT infrastructure?
A. Data analytics
B. System security
C. Hosting and managing computing resources
D. Customer support
Answer: c) Hosting and managing computing resources
,Rationale: IT infrastructure is the foundation that supports the computing resources
necessary for running applications, services, and processes, such as servers,
networks, and storage systems.
3. Which of the following is NOT a service model in cloud computing?
A. SaaS
B. PaaS
C. IaaS
D. BaaS
Answer: d) BaaS
Rationale: The primary service models in cloud computing are SaaS (Software as a
Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service). BaaS
(Backend as a Service) is not a recognized cloud service model.
4. What is the purpose of a hypervisor in cloud computing?
A. Data storage management
B. Virtualization of hardware resources
C. Security management
,D. Network traffic optimization
Answer: b) Virtualization of hardware resources
Rationale: A hypervisor is a software layer that allows multiple virtual machines
(VMs) to run on a single physical machine by virtualizing hardware resources.
5. Which cloud deployment model provides cloud services over the internet to
multiple organizations?
A. Private Cloud
B. Hybrid Cloud
C. Public Cloud
D. Community Cloud
Answer: c) Public Cloud
Rationale: In a public cloud, services are delivered over the internet and shared
across multiple users or organizations, providing scalability and cost efficiency.
6. What is the key benefit of Cloud Storage?
A. Local data processing
B. Centralized data access and backup
, C. Dependency on physical storage devices
D. High energy consumption
Answer: b) Centralized data access and backup
Rationale: Cloud storage allows users to store data remotely, providing easy
access, scalability, and backup features across multiple devices.
7. Which cloud service model allows users to develop and deploy applications
without managing underlying infrastructure?
A. IaaS
B. SaaS
C. PaaS
D. DaaS
Answer: c) PaaS
Rationale: PaaS (Platform as a Service) provides a platform that enables
developers to build, deploy, and manage applications without dealing with the
complexities of underlying infrastructure.
8. Which of the following is a major benefit of Cloud Computing for businesses?
A. Scalability
B. Limited access
C. Hardware dependency
