Question 164 of 250 from exam 400-201: Cisco CCIE Service Provider Written Exam

Question

Which description of SaaS is true?

Answers

Explanations

A. B. C. D.

D.

SaaS stands for Software as a Service. It is a cloud computing model that offers software applications to end-users through the internet. The correct answer to the question is:

D. A service offering on-demand licensed applications for end-users.

Explanation:

Option A is describing a PaaS (Platform as a Service) model that offers a platform for developers to build and deploy their own applications.

Option B is describing a download service where software can be downloaded on-demand, but it is not necessarily licensed or provided as a service.

Option C is describing another cloud computing model, IaaS (Infrastructure as a Service), which offers developers the infrastructure necessary to build their own applications.

Therefore, option D is the only description that accurately characterizes SaaS. In SaaS, software applications are provided as a service on-demand to end-users through the internet. The applications are licensed and hosted by the provider, who maintains and updates them regularly. End-users can access the applications through a web browser or a dedicated client application, without having to install or manage the software themselves. Examples of SaaS applications include Google Workspace, Salesforce, and Microsoft 365.
