4. Refer to Scenario 7.
"
A web hosting company has been growing steadily over the past year. Their single data center is at maximum capacity for power, space and cooling, and their physical infrastructure is also running at capacity. They are evaluating the feasibility of obtaining another data center in a remote location to enable further growth.
One of the web hosting company's eCommerce customers notifies them that they are launching an enormous holiday sale, beginning in a few weeks. They expect utilization of their virtual server farm to double or triple for the next three to six months. The web hosting company cannot deploy the needed resources in a new data center in time for the sale. They opt to purchase services from a cloud service provider using a pay-as-you-go model.
Over the next two weeks, Layer 2 connectivity is established between the two sites. The web hosting company's IT staff works with the CSP to configure the necessary physical and virtual infrastructure. All traffic to the public cloud is routed through the private data center, across the Layer 2 connection. A local load balancer is deployed in the private data center. Orchestration tools are configured to burst the service into the public cloud automatically when utilization reaches 80%."
During the next month, you are contacted by the billing department. They are unsure why the usage charges for the company have remained constant for several months. You know for certain that their services have been bursting into the public cloud frequently over the past two weeks.
What is the most likely course of action to identify the problem?

A) Check the details of the service offering and service contract to ensure a pay-as-you-go model is utilized
B) Investigate the pricing units in the accounting model to verify that the utility and activity costs are accurate and current
C) Confirm that the configuration of the orchestration engine polls the correct data from the CSP
D) Terminate the contract with the CSP and sign a contract with a public provider that better integrates with the solution
