Question 4

Cloud computing provides multiple advantages. Which of below elements is BEST described by a service’s ability to be scaled up or down as the needs changes for a particular user without requiring costly hardware changes?

A) Resource pooling
B) On-demand
C) Measured Service
D) Rapid elasticity


To some extent all these elements could apply however the question asks for the BEST description. When CompTIA puts BEST in the question that means other answers could make sense but are not the best alternative. In this case since Rapid Elasticity refers to the ability to scale layers of services, such as applications, storage space, or number of users, etc. it is the “winner”. Resource pooling, measured Service, and On-Demand can all imply some level of scalability but none of them as spot o as Rapid Elasticity.
