3. 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) Terminate the contract with the CSP and sign a contract with a public provider that better integrates with the solution
C) Investigate the pricing units in the accounting model to verify that the utility and activity costs are accurate and current
D) Confirm that the configuration of the orchestration engine polls the correct data from the CSP

4. A health care applications software company has been growing rapidly by acquiring several similar companies, which are based in other states.
IT is now struggling to provide services for developing, testing and supporting multiple application teams. For each application, customer support must frequently handle sensitive electronic medical records data that is subject to Federal compliance. No formal standards or policies have been established across application teams relative to sensitive data.
With the goal of ITaaS transformation, senior management seeks to establish IT governance. What would you recommend for a governance model, and why?

A) Hybrid, since it is the best approach during rapid growth by acquisition
B) Distributed by geography, since it enables localized control and lock down of sensitive data
C) Federated by application, since it ensures autonomy for each application team and promotes customer satisfaction
D) Centralized, since security and compliance concerns are relatively homogeneous across the enterprise

5. Refer to Scenario 5.

An innovative high-end graphics and multimedia firm with a substantially virtualized IT infrastructure wishes to consider cloud enablement next, as part of its logical progression to ITaaS.
As a first step, the firm plans to transition one relatively low-risk service -- daily backup -- to a public CSP. The existing backup strategy involves array-based cloning, followed by backup of the clones with dedicated servers. The system is functional; however, since the backup target device is due for a technology refresh, the firm is open to alternatives.
In evaluating alternatives, the key consideration is the ability to meet backup windows for daily incremental backups during the work week.
As advisor to this firm, you have conducted a quick assessment of the candidate applications and storage involved in daily backups. Relevant details are presented in the exhibit.
Your first goal in this proof-of-concept is to demonstrate one quick and successful backup run to the CSP for two different customer applications.
Which two applications would you select if your desired outcome is backup completion within the shortest possible time?
