Actual exam question for WGU's Network and Security Foundation exam

Question #: 7
Topic #: 1

[All Network and Security Foundation Questions]

A company wants to use a cloud service to obtain virtual machines with pre-installed and configured software.

Which cloud service model should be used?

ASoftware as a Service (SaaS)

BInfrastructure as a Service (IaaS)

CPlatform as a Service (PaaS)

DFunction as a Service (FaaS)

Show Suggested Answer

Suggested Answer: C

Platform as a Service (PaaS) provides a pre-configured computing environment that includes an operating system, runtime, and development tools, making it ideal for developers who want a ready-to-use platform. Examples include Google App Engine and Microsoft Azure App Services.

SaaS provides fully hosted applications, not just pre-configured virtual machines.

IaaS provides infrastructure without pre-installed software.

FaaS executes specific functions without persistent infrastructure.

Wait, can you really get pre-configured software with IaaS?

IaaS seems right, but I wonder if there's a chance they could mean SaaS if the software is really the main focus.

I'm a bit confused; I thought PaaS was for applications, but could it also include pre-configured software?

I remember practicing a question like this, and I think the answer was IaaS because it focuses on infrastructure.

I think it might be IaaS since it provides virtual machines, but I'm not entirely sure if SaaS could apply here too.

I feel like FaaS is for serverless computing, so that can't be right. IaaS seems like the best fit here.

PaaS sounds familiar, but I believe it's more about app development environments rather than just VMs.
