1. What does IaaS (Infrastructure as a Service) provide to users?
A. Ready-to-use software applications
B. Complete platforms for developing applications
C. Virtualized computing resources over the internet
D. Preconfigured hardware devices
Answer: c) Virtualized computing resources over the internet
Rationale: IaaS provides users with virtualized computing resources like virtual
machines, storage, and networking over the internet.
2. What does the concept of “elasticity” in cloud computing refer to?
A. The ability to rapidly increase or decrease computing resources
B. The physical size of cloud servers
C. The dependency on local storage
D. The use of hardware accelerators
Answer: a) The ability to rapidly increase or decrease computing resources
,Rationale: Elasticity in cloud computing allows users to quickly scale resources up
or down based on demand, which helps optimize costs and performance.
3. Which of the following is a major benefit of Cloud Computing for businesses?
A. Reduced hardware investment
B. Inability to access data remotely
C. Limited scalability
D. High fixed costs
Answer: a) Reduced hardware investment
Rationale: Cloud computing reduces the need for businesses to invest heavily in
physical hardware, as services can be accessed on-demand over the internet.
4. Which of the following is a disadvantage of Cloud Computing?
A. High up-front cost
B. Dependence on internet connectivity
C. Limited scalability
D. Lack of flexibility
Answer: b) Dependence on internet connectivity
,Rationale: Cloud computing relies on an internet connection, and without it, users
may not be able to access their data or services.
5. In a multi-cloud environment, how are cloud resources distributed?
A. Cloud resources are exclusively from one provider
B. Cloud resources are spread across multiple cloud providers for redundancy or to
avoid vendor lock-in
C. Resources are distributed to local servers only
D. All resources are handled by a single cloud provider with no external
communication
Answer: b) Cloud resources are spread across multiple cloud providers for
redundancy or to avoid vendor lock-in
Rationale: A multi-cloud strategy uses resources from multiple cloud providers to
prevent reliance on a single provider and enhance flexibility and redundancy.
6. What is the function of an API Gateway in a cloud environment?
A. Manages cloud storage access
B. Acts as a reverse proxy for routing requests
C. Provides virtual machines for cloud computing
, D. Enforces data encryption across cloud services
Answer: b) Acts as a reverse proxy for routing requests
Rationale: An API Gateway acts as a reverse proxy that routes requests from
clients to appropriate backend services, enabling efficient communication and
management in cloud applications.
7. 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.
8. What is the primary function of a cloud load balancer?
A. To encrypt sensitive cloud data
A. Ready-to-use software applications
B. Complete platforms for developing applications
C. Virtualized computing resources over the internet
D. Preconfigured hardware devices
Answer: c) Virtualized computing resources over the internet
Rationale: IaaS provides users with virtualized computing resources like virtual
