FC0-U71 Practice Question: Use a cloud service where they provide their own…
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?
⚠ Common exam trap
It's easy for candidates to 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.

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.
