Answer: Diverting traffic to instances based on the demand, Diverting traffic to instances with the least load

## Explanation Elasticity in cloud computing refers to the ability to automatically scale resources up or down based on demand. The correct answers are: - **A. Diverting traffic to instances based on the demand**: This is a key aspect of elasticity where traffic is automatically routed to instances that can handle the current demand, allowing for efficient resource utilization. - **B. Diverting traffic to instances with the least load**: This is also part of elasticity as it helps distribute traffic evenly across available resources, preventing overloading of any single instance and maintaining performance. **Why the other options are incorrect:** - **C. Diverting traffic across multiple regions**: While this relates to high availability and disaster recovery, it's not specifically about elasticity which focuses on scaling within a region or availability zone. - **D. Diverting traffic to instances with higher capacity**: This is more about load balancing based on instance capacity rather than the dynamic scaling aspect of elasticity.
