Which cloud service model provides virtualized computing resources over the internet, such as virtual machines and storage, without managing the underlying hardware?
Answer: Infrastructure as a Service (IaaS)
IaaS provides virtualized hardware resources (VMs, storage, networking) over the internet, letting users manage OS and applications while the provider handles physical infrastructure.
A company wants to use a cloud deployment model that combines on-premises infrastructure with public cloud resources and allows data and applications to move between them. Which model best describes this?
Answer: Hybrid cloud
A hybrid cloud integrates on-premises (private) infrastructure with public cloud services, enabling workloads and data to move between environments.
Which cloud characteristic allows resources to be provisioned and released automatically based on demand without human intervention?
Answer: Rapid elasticity
Rapid elasticity allows cloud resources to scale up or down automatically and quickly in response to demand, often appearing unlimited to the consumer.
An organization hosts its own cloud infrastructure exclusively for its use, managed either internally or by a third party. What type of cloud deployment is this?
Answer: Private cloud
A private cloud is operated solely for a single organization, providing greater control, security, and customization compared to public cloud.
Which cloud service model delivers applications over the internet on a subscription basis, where the provider manages all underlying infrastructure, platforms, and software?
Answer: SaaS
SaaS delivers complete applications over the internet; the provider manages everything from infrastructure to the application itself, and users simply access the software.
In cloud computing, what does 'measured service' mean?
Answer: Cloud systems automatically control and optimize resource use through metering
Measured service means cloud providers monitor, control, and report resource usage transparently, enabling pay-per-use billing.
A developer needs an environment to build, test, and deploy applications without managing servers or runtime environments. Which cloud service model should they use?
Answer: PaaS
PaaS provides a managed platform with tools, frameworks, and runtime environments for developers to build and deploy applications without managing the underlying infrastructure.
