CompTIA A+ Core 1 (220-1101) — Question 519

An online retailer wants to save money and is considering migrating to the public cloud so capacity can be added during the peak shopping season and automatically removed when the peak is over. Which of the following BEST describes this aspect of cloud computing?

Answer options

• A. Rapid elasticity
• B. Metered utilization
• C. Shared resources
• D. High availability

Correct answer: A

Explanation

The correct answer is A, Rapid elasticity, which refers to the ability to quickly scale resources up or down based on demand. The other options do not accurately describe this feature; Metered utilization relates to billing based on resource usage, Shared resources refer to the co-use of resources among multiple tenants, and High availability indicates system uptime rather than flexibility in scaling.
