Last updated Jun 24, 2026
Correct Answer:
Option A —
Networking hardware
Understanding the IaaS Model
IaaS is the most flexible cloud computing model, essentially providing the "raw materials" of computing. The service provider handles the physical infrastructure, while the user manages everything from the operating system upward.
What the Provider Manages:
Physical Data Centers: Buildings, cooling, and power.
Physical Servers: The actual blades and racks of hardware.
Networking Hardware: Routers, switches, and cabling.
Storage Hardware: Physical hard drives and arrays.
Virtualization: The software layer (hypervisor) that splits physical hardware into virtual machines.
Why the other options are incorrect:
B) Operating System: In IaaS, the user is responsible for choosing, installing, and patching the OS (e.g., Windows Server or Linux). If the provider managed the OS, it would typically be considered PaaS (Platform as a Service).
C) Hardware platform and operating system: As noted above, the OS is managed by the customer in IaaS.
D) Operating system and data: The customer always retains ownership and management of their data in IaaS, PaaS, and SaaS models
