A technician wants the number of virtual machines hosting a web application in the public cloud environment to scale based on real-time traffic on the website.
Which of the following should the technician configure?

A. B. C. D.B.
The correct answer is B. Rapid elasticity.
Rapid elasticity is a characteristic of cloud computing that enables the scaling of resources up or down in response to changes in demand. In this scenario, the technician wants to scale the number of virtual machines hosting a web application based on real-time traffic on the website. Rapid elasticity allows for automatic scaling of resources in response to changes in demand, making it the appropriate solution for this scenario.
Resource pooling is a cloud computing characteristic that allows multiple customers to share a common pool of computing resources, such as storage or processing power. While this is useful for managing resources efficiently, it is not directly related to scaling based on traffic.
Measured service is a cloud computing characteristic that enables the monitoring and billing of cloud services based on usage. This is useful for tracking costs and ensuring that customers only pay for what they use. However, it is not directly related to scaling based on traffic.
High availability is a characteristic of cloud computing that ensures that services are available and accessible at all times. This is achieved through redundancy and failover mechanisms. While this is important for ensuring the availability of services, it is not directly related to scaling based on traffic.
In summary, the technician should configure rapid elasticity to enable the automatic scaling of resources in response to changes in demand.
