Which feature associated with an Infrastructure as a Service (IaaS) cloud service provider allows for the provisioning of new servers as demand changes?

Answer options

• A. Measured service
• B. Resource pooling
• C. Rapid elasticity
• D. Load balancing

Correct answer: C

Explanation

The correct answer is C, Rapid elasticity, as it refers to the ability to quickly scale resources up or down based on demand.
