1. The IT department and lines of business at a pharmaceutical company are determining what the best resource allocation and chargeback models would be to fund their development efforts.
The primary drivers are:
-Guaranteed resources are always available -Applications should be able to burst quickly on-demand -SLAs are negotiable
Which best meets the requirements?

A) A variable resource allocation model. Each LOB is billed one rate for both the resources used within the guaranteed pool and shared pool.
B) A variable resource allocation model. Each LOB is billed one rate for the resources used within the guaranteed pool and a different rate for the resources used within the shared pool.
C) A guaranteed allocation model. Each LOB is billed one rate for both the resources used within the guaranteed pool and the shared pool.
D) A guaranteed allocation model. Each LOB is billed one rate for the resources used within the guaranteed pool and a different rate for the resources used within the shared pool.

2. An IT organization is currently 80% virtualized and the CIO is planning for the transition to ITaaS. The organization has already experienced significant savings due to virtualization. Senior executives are concerned that ITaaS requires additional software licenses and additional headcount, both at significant cost.
How can the CIO convince senior management of the savings potential with ITaaS?

A) Show how the service catalog and orchestration tools can be viewed in the context of "cost to serve" to provide immediate business value
B) Explain that the service catalog can be a mechanism for controlling cost by influencing LOB/consumer behavior through showback/chargeback
C) Propose that the CMDB and orchestration tool will decrease the cost of service management
D) Explain to senior management that there will not be any additional skill sets required for the ITaaS initiative

3. Which risk domain(s) is a concern when end users independently leverage the public cloud outside the management of corporate IT?

A) Accessibility and Ease of use
B) Non-repudiation
C) Availability and Control
D) FIPS-140 enforcement

4. An enterprise has decided to implement a new service that will process credit card information.
They will deploy this service within a hybrid cloud.
Their public cloud provider claims to be PCI DSS compliant. The enterprise wishes to implement a service that is PCI compliant with the least amount of effort. The service is protected by a policy based intrusion detection system. Cardholder data is securely transmitted to the web interface.
Which additional design elements would best be suited for this implementation?

A) The card number is masked as it is typed and is immediately encrypted and securely sent directly to the credit card processing system. Credit card information is stored using AES 128 encryption within the public cloud provider or within the private cloud, depending on the location of the service.
B) The card number is masked as it is typed and is immediately encrypted and securely sent directly to the credit card processing system. No credit card information is stored within the application.
C) The card number is masked as it is typed and is immediately encrypted and securely sent to both the credit card processing system and to the private cloud for historical tracking and reporting only.
D) The card number is masked as it is typed and is immediately encrypted and securely sent directly to the credit card processing system. Credit card information is only stored in the public cloud provider's systems using AES 128 encryption.

5. Refer to Scenario 1 below.
An IT department is offering 50 Service Offerings in their service catalog to meet all the application developers' needs. Many of the variants have a very small number of associated instantiations. A "big data" platform is offered and being actively utilized by a team of data scientists.
All services are sourced from within the private cloud. The developers are able to customize the platform's compute, storage, protection and network configuration upon instantiation. They can also provision additional resources after the initial instantiation through an upgrade service within the catalog. Because of the culture of the organization, no chargeback mechanism is implemented.
Within six months, IT experiences these problems:
(a). Developers are complaining of poor and inconsistent performance
(b). Resource utilization has far exceeded expectations
(c). The environment has become very complex
(d). Since the resource pools are shared throughout the organization, IT has been unable to identify usage patterns, making capacity planning very difficult
What can the IT department do to address problem (a)?

A) Communicate appropriate SLAs that are realistic given the demand and resources available
B) Divide the "application developer" and "big data" workloads into separate resource pools
C) Standardize on a subset of offerings to meet the needs of most developers and minimize the number of customization options
D) Offer additional, larger resource platform options to the developers
