Identify the correct cloud service model for a virtual machine

You create and manage a virtual machine on Google Compute Engine. Which cloud service model does this represent?

A Function as a Service (FaaS)

B Infrastructure as a Service (IaaS)

C Software as a Service (SaaS)

D Platform as a Service (PaaS)

💡 Hint

Think about who manages the hardware and who manages the software.

In IaaS, you manage virtual machines and operating systems, while the cloud provider manages the physical hardware.

Choose the service model for Google App Engine

Google App Engine lets you deploy applications without managing the underlying servers. Which cloud service model is this?

A Platform as a Service (PaaS)

B Software as a Service (SaaS)

C Infrastructure as a Service (IaaS)

D Container as a Service (CaaS)

💡 Hint

Focus on the level of control you have over the environment.

PaaS provides a platform to deploy and manage applications without handling the infrastructure.

Determine the cloud service model for Google Workspace

Google Workspace offers email, document editing, and collaboration tools accessible via a web browser. What cloud service model does this represent?

A Backend as a Service (BaaS)

B Platform as a Service (PaaS)

C Software as a Service (SaaS)

D Infrastructure as a Service (IaaS)

💡 Hint

Consider if you install or manage the software yourself.

SaaS delivers software applications over the internet managed by the provider.

❓ security

advanced

Identify responsibility in shared security for IaaS

In an IaaS model like Google Compute Engine, which security responsibility is typically handled by the user?

A Operating system patching and updates

B Physical data center security

C Network infrastructure maintenance

D Hardware failure management

💡 Hint

Think about what you control versus what the provider controls.

In IaaS, users manage the OS and applications, including patching and updates.

❓ service_behavior

Predict behavior when scaling a PaaS application

You deploy a web app on Google App Engine and configure automatic scaling. What happens when traffic suddenly spikes?

A Google App Engine shuts down instances to reduce costs

B You must manually create new virtual machines to handle the traffic

C The application will crash because scaling is not supported

D Google App Engine automatically adds more instances to handle the load

💡 Hint

Consider how PaaS services handle scaling for you.

PaaS platforms like Google App Engine automatically scale instances based on traffic.
