1. Which statement BEST describes the primary purpose of cloud
computing?
A. To eliminate the need for all physical computing hardware
B. To provide on-demand access to configurable computing resources
over a network
C. To ensure that every application runs on a dedicated physical server
D. To replace all enterprise IT employees with automated systems
Answer: B. To provide on-demand access to configurable computing
resources over a network
Rationale: Cloud computing provides on-demand access to shared and
configurable resources such as compute, storage, networking,
applications, and services. The resources can generally be provisioned,
scaled, and released according to organizational requirements. Cloud
computing does not eliminate physical hardware; rather, it abstracts
much of that infrastructure from the consumer.
2. A company wants to consume a cloud-hosted application without
managing the operating system, middleware, runtime, or underlying
infrastructure. Which service model is MOST appropriate?
A. Infrastructure as a Service (IaaS)
B. Platform as a Service (PaaS)
1
,C. Software as a Service (SaaS)
D. Bare Metal as a Service (BMaaS)
Answer: C. Software as a Service (SaaS)
Rationale: SaaS delivers a complete application to the customer. The
cloud provider typically manages the application platform, operating
system, runtime, infrastructure, and underlying hardware. IaaS gives
the customer substantially more responsibility, while PaaS generally
allows customers to deploy applications without managing the
underlying operating system and infrastructure.
3. A development team wants to deploy its application code while
allowing the cloud provider to manage the operating system,
servers, storage, and networking. Which cloud model BEST fits this
requirement?
A. SaaS
B. PaaS
C. IaaS
D. Colocation
Answer: B. PaaS
Rationale: Platform as a Service provides developers with a managed
application platform. Developers concentrate on application code and
configuration while the provider manages much of the infrastructure
and operating-system stack. This reduces infrastructure-management
responsibilities compared with IaaS.
4. Which characteristic of cloud computing allows an organization
to automatically increase resources when demand rises?
2
,A. Resource pooling
B. Elasticity
C. Measured service
D. Broad network access
Answer: B. Elasticity
Rationale: Elasticity is the ability to dynamically provision or release
resources in response to changing demand. For example, an online
retailer may automatically add compute instances during a major sales
event and remove them afterward. Resource pooling concerns shared
provider resources, measured service concerns metering and usage
measurement, and broad network access concerns accessibility
through network-connected devices.
5. An organization pays only for the amount of cloud storage and
compute resources it actually consumes. Which cloud characteristic
does this BEST demonstrate?
A. Measured service
B. Fault tolerance
C. Multitenancy
D. Portability
Answer: A. Measured service
Rationale: Measured service means cloud resource usage can be
monitored, controlled, reported, and often billed according to
consumption. This characteristic supports consumption-based pricing
models in which customers pay according to their actual or allocated
resource usage.

, 6. A company operates its own cloud infrastructure exclusively for
use by its departments and employees. Which deployment model is
being used?
A. Public cloud
B. Private cloud
C. Community cloud
D. Multicloud
Answer: B. Private cloud
Rationale: A private cloud is dedicated to a single organization. It may
be hosted on the organization's premises or operated by a third party,
but the infrastructure is dedicated to that organization. A public cloud
serves multiple customers, while a community cloud is designed for
organizations sharing common requirements.
7. An organization uses a private cloud for sensitive workloads but
uses a public cloud for customer-facing applications. Which
deployment model BEST describes this environment?
A. Hybrid cloud
B. Community cloud
C. Private cloud only
D. Dedicated hosting
Answer: A. Hybrid cloud
Rationale: A hybrid cloud combines two or more distinct cloud
environments, commonly private and public cloud infrastructure, with
some form of integration or interoperability. Organizations often use
hybrid models to keep sensitive workloads in private environments
while taking advantage of public-cloud scalability.
