1. Which of the following is the best description of "virtualization" in IT
infrastructure?
A. The process of converting physical hardware into virtual resources
B. The creation of a backup for cloud data
C. The process of encrypting data for security purposes
D. The process of manually managing server resources
Answer: a) The process of converting physical hardware into virtual resources
Rationale: Virtualization allows multiple virtual machines to run on a single
physical machine by abstracting hardware resources, leading to better resource
utilization.
2. Which of the following best describes the relationship between Cloud
Computing and virtualization?
A. Cloud computing is a form of virtualization
B. Virtualization is a key enabler of cloud computing
C. Cloud computing does not require virtualization
,D. Virtualization is used only for data storage in cloud computing
Answer: b) Virtualization is a key enabler of cloud computing
Rationale: Virtualization technology is fundamental to cloud computing, allowing
resources like computing power and storage to be abstracted and shared
dynamically.
3. Which of the following cloud providers offers IaaS?
A. Dropbox
B. Google App Engine
C. Amazon Web Services (AWS)
D. Microsoft Office 365
Answer: c) Amazon Web Services (AWS)
Rationale: AWS is a leading cloud provider offering Infrastructure as a Service
(IaaS), providing virtualized computing resources such as storage, computing
power, and networking.
4. What is a "Cloud Broker"?
A. A tool used to manage cloud data storage
,B. A company that helps businesses select and manage cloud services
C. A cloud service provider that offers Infrastructure as a Service
D. A type of cloud storage platform
Answer: b) A company that helps businesses select and manage cloud services

5. What does the term "multi-tenancy" refer to in the context of Cloud Computing?
A. The use of multiple cloud providers for redundancy
B. The sharing of cloud resources by multiple users or organizations
C. The use of separate infrastructure for different users
D. The ability to upgrade cloud services without downtime
Answer: b) The sharing of cloud resources by multiple users or organizations
Rationale: In a multi-tenant cloud model, multiple organizations share the same
cloud infrastructure while maintaining data isolation and security.
6. Which of the following is an example of a “Platform as a Service” (PaaS)
offering for database management?
, A. Amazon EC2

7. Which of the following best describes a "Cloud-Native" application?
A. A traditional on-premise application hosted on the cloud
B. A cloud application designed and built to leverage cloud-specific services, such
as scalability and availability
C. An application that only runs on local servers
D. A simple web application with minimal resource requirements
Answer: b) A cloud application designed and built to leverage cloud-specific
services, such as scalability and availability
Rationale: Cloud-native applications are designed specifically to take full
advantage of cloud environments, including features like scalability, resilience, and
elasticity.
