CompTIA Cloud Computing Fundamentals 1 — Questions and Answers
Question 1: Which cloud service model provides virtualized computing resources over the internet, such as virtual machines and storage, without managing the underlying hardware?
- Software as a Service (SaaS)
- Platform as a Service (PaaS)
- Infrastructure as a Service (IaaS) (Correct answer)
- Function as a Service (FaaS)
Correct 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.
Question 2: 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?
- Private cloud
- Public cloud
- Hybrid cloud (Correct answer)
- Community cloud
Correct answer: Hybrid cloud
A hybrid cloud integrates on-premises (private) infrastructure with public cloud services, enabling workloads and data to move between environments.
Question 3: Which cloud characteristic allows resources to be provisioned and released automatically based on demand without human intervention?
- Broad network access
- Resource pooling
- Rapid elasticity (Correct answer)
- Measured service
Correct 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.
Question 4: 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?
- Public cloud
- Private cloud (Correct answer)
- Hybrid cloud
- Multicloud
Correct answer: Private cloud
A private cloud is operated solely for a single organization, providing greater control, security, and customization compared to public cloud.
Question 5: Which cloud service model delivers applications over the internet on a subscription basis, where the provider manages all underlying infrastructure, platforms, and software?
- IaaS
- PaaS
- SaaS (Correct answer)
- DaaS
Correct 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.
Question 6: In cloud computing, what does 'measured service' mean?
- Resources are available from any network-connected device
- Cloud systems automatically control and optimize resource use through metering (Correct answer)
- Resources can be provisioned without human interaction
- Multiple customers share the same physical resources
Correct 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.
Question 7: A developer needs an environment to build, test, and deploy applications without managing servers or runtime environments. Which cloud service model should they use?
- IaaS
- PaaS (Correct answer)
- SaaS
- NaaS
Correct 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.
