Q

What are two characteristics of a consumption-based model?

1.high capital expenditures
2.no upfront costs
3.requires the purchase and management of the physical infrastructure
4.the ability to stop paying for resources that are no longer used

A

*The ability to stop paying for resources that are no longer used
*No upfront costs

In a consumption-based model, you do not pay for anything until you start using resources, and you only pay for what you use. If you stop using a resource, you stop paying for it. High expenditures are usually associated with the purchase of the physical infrastructure, which is not needed in a consumption-based model.

Q

Which cloud service model provides you with the most control over the hardware that runs applications?

1.infrastructure as a service (IaaS)
2.platform as a service (PaaS)
3.software as a service (SaaS)

A

infrastructure as a service (IaaS)

IaaS is the most flexible category of cloud services. It aims to give you complete control over the hardware that runs applications. Users do not control the operating system and do not configure the underlying servers in PaaS. With SaaS, you are using as-is software hosted in the cloud, instead of creating a platform to host a software yourself.

Q

Your organization is building a custom application. You need to focus on application development rather than configuration and management of servers. Which cloud service model should you use?

1.infrastructure as a service (IaaS)

2.platform as a service (PaaS)

3.software as a service (SaaS)

A

platform as a service (PaaS)

With PaaS, users can focus on application development because the cloud provider handles all the platform management. In SaaS, the cloud provider manages all aspects of the application environment, such as virtual machines, networking resources, data storage, and applications.
