CCNA: Cisco Certified Network Associate — Question 710

In a cloud-computing environment, what is rapid elasticity?

Answer options

• A. control and monitoring or resource consumption by the tenant
• B. automatic adjustment of capacity based on need
• C. pooling resources in a multitenant model based on need
• D. self-service of computing resources by the tenant

Correct answer: B

Explanation

The correct answer is B, as rapid elasticity enables automatic scaling of resources to meet changing demand. Options A, C, and D do not capture the essence of elasticity, which specifically refers to the dynamic scaling of resources rather than monitoring, pooling, or self-service capabilities.
