A virtual file server in the cloud is configured to automatically add compute resources during times of high load on the server. Which of the following describes this cloud feature?

The correct answer is C. Rapid elasticity. Rapid elasticity is one of the five essential characteristics of cloud computing as defined by NIST. It describes the ability to automatically scale computing resources up or down in response to demand, such as adding CPU or memory during high load. File synchronization (A)…

Explanation

Rapid elasticity is one of the five essential characteristics of cloud computing as defined by NIST. It describes the ability to automatically scale computing resources up or down in response to demand, such as adding CPU or memory during high load. File synchronization (A) keeps data consistent across devices. High availability (B) focuses on uptime and redundancy, not dynamic resource scaling. Shared resources (D) refers to resource pooling among multiple tenants, not automatic scaling.
