A university migrating class registration to a CSP seeks to support variable demand during peak registration periods; what benefit is most important?

• A. Rapid Elasticity
• B. Data Security
• C. Cost Optimization
• D. Public Cloud

Answer: (A)

Rapid elasticity is the cloud trait that lets resources scale quickly to match changing demand. In a university’s peak class registration period, demand can surge dramatically in a short time and then drop just as fast when registration ends. Rapid elasticity lets the system automatically add more compute power, memory, and database capacity as needed and then scale back down when the rush is over. This ensures performance and responsiveness for students trying to register, while avoiding the costs of maintaining excess capacity year-round.

Data security is essential, but it doesn’t address fluctuations in load. Cost optimization is related, since elasticity helps control costs by paying for what you use, but the primary benefit in this scenario is the ability to handle variable demand. Public cloud describes the deployment model rather than the benefit being sought.
