CCSP Cloud Concepts, Architecture, and Design Practice Question
Which cloud characteristic refers to the ability to automatically scale resources up or down based on demand?
⚠ Common exam trap
The trap is that candidates might confuse rapid elasticity with other characteristics like resource pooling or measured service, especially since all are fundamental to cloud computing.

Correct answer & explanation
✓
Rapid elasticity
Rapid elasticity is the cloud characteristic that allows resources to be automatically scaled up or down based on demand. It enables cloud consumers to quickly provision and release resources to match workload fluctuations, often in an automated manner. This is a core tenet of cloud computing as defined by NIST.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Resource pooling
Why it's wrong here
Resource pooling describes providers serving multiple consumers from shared physical or virtual resources, delivering location independence. It is tempting because pooled resources underpin scaling, but the automatic up-and-down adjustment of capacity based on demand is elasticity, not pooling.
- ✓
Rapid elasticity
Why this is correct
Rapid elasticity describes resources scaling automatically up or down to match demand, appearing unlimited to the consumer. This directly satisfies the stem's automatic scaling characteristic, distinguishing it from measured service, on-demand self-service and broad network access, which address provisioning, metering and connectivity instead.
- ✗
Broad network access
Why it's wrong here
Broad network access means services are reachable over the network through standard mechanisms and diverse client devices. It is tempting because scaling depends on network reachability, but the characteristic describing automatic capacity adjustment to match demand is elasticity, not accessibility.
- ✗
Measured service
Why it's wrong here
Measured service describes metering and billing of consumption, not elasticity. It is tempting because autoscaling changes the resources consumed, which the provider then measures, but the characteristic that names automatic scale-up and scale-down on demand is rapid elasticity.
