CCSP Cloud Concepts, Architecture, and Design Practice Question
In the NIST SP 800-145 definition of cloud computing, which characteristic is described as the capability to rapidly and elastically provision and release resources, often automatically?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Rapid elasticity
Rapid elasticity is the defined characteristic. Measured service is about metering, resource pooling is about sharing, broad network access is about network availability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Rapid elasticity
Why this is correct
Rapid elasticity allows quick scaling of resources.
- ✗
Resource pooling
Why it's wrong here
Resource pooling is about multi-tenant shared resources.
- ✗
Broad network access
Why it's wrong here
Broad network access describes network-accessible capabilities available through standard protocols, not the automated scaling of resource allocation. It is tempting because broad network access enables the remote provisioning that elastic systems rely on, but the stem specifically asks for the characteristic governing the speed and automation of resource release and acquisition—which is rapid elasticity, not network reach. Broad network access would be correct if the question focused on multi-platform accessibility via mobile phones, laptops, or workstations.
- ✗
Measured service
Why it's wrong here
Measured service is about metering and usage monitoring.
