You are the Service Consumer In the Cloud Shared Responsibility Model. Which three are your responsibility when using the Infrastructure as a Service (IaaS)?

Question

Options

• Aapplication
• Bhost Infrastructure
• Cnetwork
• Ddata
• Ephysical
• Fguest OS
• Gvirtualization
• Hdatabase

• B
  95% (19)
• E
  5% (1)

Explanation

Important note: The answer key provided (B, F, G) appears to conflict with the standard Cloud Shared Responsibility Model. In the universally accepted IaaS model, Host Infrastructure (B) and Virtualization (G) are the cloud provider's responsibilities, not the consumer's. This answer key may contain an error.

What the standard model actually says for IaaS service consumers:

In IaaS, the cloud provider handles the "undifferentiated heavy lifting" - Physical (E), Host Infrastructure (B), Network physical layer (C), and Virtualization (G). The consumer takes over above the hypervisor.

Customer responsibilities in IaaS are: A, D, F, H

• F (Guest OS) - You choose, install, and patch your operating system
• A (Application) - You deploy and maintain your software
• D (Data) - You own and secure your data
• H (Database) - You manage your database engine and configs

Why the distractors are "wrong" (from the provider's side):

• B (Host Infrastructure) - Provider manages physical servers/hosts
• C (Network) - Provider manages physical network fabric
• E (Physical) - Provider owns the data center
• G (Virtualization) - Provider manages the hypervisor layer

Memory tip: Think of IaaS as renting an empty apartment. The landlord (provider) handles the building (physical), plumbing (network), and walls (virtualization/host). You furnish it - OS, apps, data, database.

Recommendation: Verify this question against your official course material, as the answer key (B, F, G) does not align with standard IaaS definitions from AWS, Azure, NIST, or CompTIA curricula.
