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%."
After viewing the weekly trending analysis, you notice that the cost of resources allocated does not correspond to resource utilization. And the billing statement from the cloud service provider (CSP) reflects higher than expected charges.
What is the most effective action to take to rectify the discrepancy?
A. Contact the CSP representative and negotiate a fixed cost model
B. Verify that the orchestration engine is configured to trigger the collapse of the underutilized resources
C. Contact the CSP representative and renegotiate the terms of service of the contract
D. Terminate the contract with the CSP and sign a contract with a public provider that better integrates with the solution
