Which design principle of secure cloud computing ensures that users have access to a large...

Rapid elasticity is the design principle that ensures cloud resources can grow or shrink dynamically based on user demand. Managing Cloud principles explain that rapid elasticity allows cloud systems to automatically scale resources such as compute, storage, and bandwidth in near real time.

This capability ensures that users experience consistent performance even during sudden increases in workload. Resources are provisioned when needed and released when demand decreases, enabling efficient utilization and cost control. From a security perspective, elasticity also supports resilience and availability by preventing resource exhaustion.

Resource pooling enables shared infrastructure, virtualization enables abstraction, and collaboration is not a cloud design principle. Therefore, rapid elasticity is the correct answer.
