CCNA: Cisco Certified Network Associate — Question 296

A manager asks a network engineer to advise which cloud service models are used so employees do not have to waste their time installing, managing, and updating software that is only used occasionally. Which cloud service model does the engineer recommend?

Answer options

• A. infrastructure-as-a-service
• B. platform-as-a-service
• C. business process as service to support different types of service
• D. software-as-a-service

Correct answer: D

Explanation

The correct answer is D, software-as-a-service, because it provides users with access to software applications over the internet without the need for local installation or management. Options A and B involve more infrastructure or platform management, and C does not specifically address software delivery, making them less suitable for the scenario presented.
