,CHAPTER 1 CLOUD COMPUTING ESSENTIALS
1. Which of the following is a core characteristic of cloud computing?
a) Proprietary software
b) Resource pooling
c) Fixed infrastructure
d) Manual scaling
Answer: b) Resource pooling
Rationale: Cloud computing provides shared resources to multiple consumers using a
multi-tenant model, which is called resource pooling. This allows for efficient resource
allocation and scalability.
2. Which cloud computing model provides users with the highest level of control
over the hardware and software environment?
a) Software as a Service (SaaS)
b) Platform as a Service (PaaS)
c) Infrastructure as a Service (IaaS)
d) Network as a Service (NaaS)
Answer: c) Infrastructure as a Service (IaaS)
Rationale: IaaS allows users to manage underlying hardware, operating systems, and
networks. SaaS provides the least control, while PaaS offers some flexibility but not
over hardware infrastructure.
3. What is the primary advantage of cloud computing over traditional IT
infrastructure?
a) High initial capital expenditure
b) Centralized control
,c) Elastic scalability
d) Hardware dependency
Answer: c) Elastic scalability
Rationale: Cloud computing enables resources to scale up or down dynamically,
depending on demand, without the need for large upfront investments in hardware.
4. Which deployment model provides cloud services that are exclusively used by
a single organization?
a) Public cloud
b) Hybrid cloud
c) Private cloud
d) Community cloud
Answer: c) Private cloud
Rationale: A private cloud is owned and operated by a single organization, providing
greater control and security compared to public cloud services.
5. Which cloud service model is best suited for developers who need an
environment to build and deploy applications without managing underlying
infrastructure?
a) Infrastructure as a Service (IaaS)
b) Platform as a Service (PaaS)
c) Software as a Service (SaaS)
d) Function as a Service (FaaS)
Answer: b) Platform as a Service (PaaS)
Rationale: PaaS offers developers an environment for building applications without
having to worry about managing servers, storage, or networking.
, 6. Which of the following is a major security concern in cloud computing
environments?
a) Data localization
b) Vendor lock-in
c) Physical access to hardware
d) Multi-tenancy
Answer: d) Multi-tenancy
Rationale: In cloud computing, multi-tenancy means that resources are shared among
multiple users, raising concerns about data isolation, privacy, and potential breaches.
7. In cloud computing, which term refers to the practice of automatically scaling
resources based on real-time demand?
a) Manual provisioning
b) Horizontal scaling
c) Auto-scaling
d) Vertical scaling
Answer: c) Auto-scaling
Rationale: Auto-scaling allows cloud resources to be adjusted automatically based on
the needs of the applications, optimizing resource use and costs.
8. Which type of cloud service model is designed for end-users who need to
access software applications over the internet?
a) IaaS
b) SaaS
c) PaaS
d) FaaS
