This FC0-U61 practice question tests your understanding of it concepts and terminology. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are examples of cloud computing service models?
PaaS
PaaS provides a platform for developing and deploying applications.
IaaS
IaaS provides virtualized computing resources over the internet.
LAN
Why wrong: LAN is a local area network, not a cloud service model.
SAR
Why wrong: SAR is not a recognized cloud service model.
WAN
Why wrong: WAN is a wide area network, not a cloud service model.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
PaaS
PaaS (Platform as a Service) is a cloud computing service model that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure. It includes operating systems, middleware, development tools, and database management, making it a core cloud service model alongside IaaS and SaaS.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
PaaS
Why this is correct

LAN
Why it's wrong here
LAN is a local area network, not a cloud service model.
SAR
Why it's wrong here
SAR is not a recognized cloud service model.
WAN
Why it's wrong here
WAN is a wide area network, not a cloud service model.
Common exam traps
The trap here is that candidates may confuse network types (LAN, WAN) or unfamiliar acronyms (SAR) with cloud service models, especially since the exam often includes plausible-sounding but incorrect options to test recognition of the standard NIST-defined models.
Detailed technical explanation
Cloud computing service models are defined by the National Institute of Standards and Technology (NIST) in SP 800-145, which specifies three primary models: IaaS, PaaS, and SaaS. PaaS abstracts the underlying hardware and OS, allowing developers to deploy code using runtime environments like Google App Engine or AWS Elastic Beanstalk, while IaaS provides virtualized compute resources such as EC2 instances. Understanding these models is critical for cost optimization and operational responsibility boundaries in cloud architecture.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
