Quick Answer
The correct answer is Infrastructure as a Service (IaaS). This is because IaaS is the cloud service model where the customer manages the operating system and applications, while the cloud provider manages the physical hardware and virtualization layer, including the hypervisor and underlying servers. On the CompTIA ITF+ FC0-U61 exam, this question tests your ability to distinguish between the three core service models—IaaS, PaaS, and SaaS—by focusing on the boundary of administrative control. A common trap is confusing IaaS with PaaS, but remember: in PaaS, the provider also manages the OS, leaving the customer only to deploy their own applications. For a quick memory tip, think of IaaS as “I am the admin of the OS,” where you bring your own operating system and software stack, while the provider handles the physical infrastructure beneath it.
This FC0-U61 practice question tests your understanding of infrastructure. 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.
A company wants to use a cloud service where they provide their own operating system and applications, but the provider manages the physical hardware and virtualization layer. Which cloud service model does this describe?
Platform as a Service (PaaS)
Why wrong: PaaS abstracts the OS, customers only deploy apps.
Infrastructure as a Service (IaaS)
IaaS gives virtual machines where customers manage OS and applications.
Desktop as a Service (DaaS)
Why wrong: DaaS delivers virtual desktops, not full control over the OS.
Software as a Service (SaaS)
Why wrong: SaaS provides ready-to-use software, not control over OS.

Correct answer & explanation
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, where the customer manages the operating system, applications, and middleware, while the cloud provider handles the physical hardware, storage, and network infrastructure. In this model, the provider manages the virtualization layer (hypervisor) and underlying physical servers, but the customer retains full control over the OS and applications, matching the scenario exactly.
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.
Platform as a Service (PaaS)
Why it's wrong here
PaaS abstracts the OS, customers only deploy apps.
Infrastructure as a Service (IaaS)
Why this is correct
IaaS gives virtual machines where customers manage OS and applications.

Desktop as a Service (DaaS)
Why it's wrong here
DaaS delivers virtual desktops, not full control over the OS.
Software as a Service (SaaS)
Why it's wrong here
SaaS provides ready-to-use software, not control over OS.
Common exam traps
The trap here is that candidates often confuse PaaS with IaaS because both involve cloud infrastructure, but PaaS abstracts away the OS management, whereas IaaS gives the customer full OS control, which is the key differentiator in this scenario.
Detailed technical explanation
Under the hood, IaaS relies on a hypervisor (e.g., VMware ESXi, KVM, or Hyper-V) to partition physical hardware into virtual machines (VMs). The provider manages the hypervisor and physical hosts, while the customer installs and configures their own guest OS (e.g., Windows Server or Linux distribution) on the VM. A real-world example is AWS EC2, where customers launch instances with their chosen AMI, manage the OS patches, and install applications, while AWS handles the physical servers and virtualization layer.
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.
