APlatform as a Service (PaaS)
BInfrastructure as a Service (IaaS)
CSoftware as a Service (SaaS)
DNetwork as a Service (NaaS)

  1. Step 1: Understand PaaS expectations

    PaaS should handle OS and runtime installation automatically.

  2. Step 2: Identify the error

    Manually installing OS means the platform is acting like IaaS, not PaaS.

  3. Final Answer:

    Platform as a Service (PaaS) -> Option A

  4. Quick Check:

    PaaS = no manual OS install [OK]
Quick Trick: PaaS hides OS setup; manual means wrong model [OK]
Common Mistakes:
MISTAKES
  • Assuming manual install fits PaaS
  • Confusing IaaS with PaaS
  • Ignoring SaaS and NaaS differences
