For a volatile cloud-based class registration portal, which capability enables handling peak load without downtime?

• A. Data Backup
• B. Detailed Logging
• C. Rapid Elasticity
• D. Cloud Elasticity

Answer: (C)

Handling sudden, high traffic without downtime relies on the ability to scale resources quickly as demand changes. That capability is rapid elasticity—the cloud property that automatically provisions and deprovisions computing resources in response to traffic. When registrations spike, the system can automatically add more servers or services and balance the load so the portal stays responsive. Data backup focuses on recovery after failures; detailed logging aids monitoring and debugging but doesn’t prevent outages; cloud elasticity is a broader idea, but rapid elasticity emphasizes the fast, automatic scaling needed to handle peak load smoothly.
