A) Implement multi-tenancy trust zones through the service catalog for regulated data. Implement
RBAC through the service catalog to protect student, faculty and staff data. Create resource pools to support the performance characteristics.
B) Implement multi-tenancy trust zones through the service catalog for students, faculty, and staff.
Implement RBAC through the service catalog to protect regulated data.
Create resource pools to support the performance characteristics.
C) Implement multi-tenancy trust zones through the service catalog for students, faculty, and staff.
Implement IT security mechanisms to protect regulated data.
Create resource pools to support the performance characteristics.
D) Implement multi-tenancy trust zones through the service catalog for students, faculty, and staff.
Implement service orchestration to support the performance requirements.

2. Refer to Scenario 5.
Refer to the exhibit.

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.
-- Exhibit -
Another evaluation point is the completion time for weekly full backups to the cloud service provider. Which would have the most favorable impact on full backup speed?

A) Source-based deduplication
B) Target-based deduplication
C) Use of thin provisioning for volumes
D) Low capacity growth rate for volumes

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

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

4. A software company recently entered into a cooperative development agreement with four global companies to develop control software for a manufacturing business. The software development team will use a development environment that includes ADA compilers and MySQL hosted by the manufacturer.
Which service delivery model should the manufacturing company use?

A) Application-as-a-Service
B) Platform-as-a-Service
C) Software-as-a-Service
D) Infrastructure-as-a-Service

5. A hosting organization operates from two data centers and typically hosts very large customers. The delivery and support of the IT Infrastructure is not service driven. The IT technical delivery functions operate in silos. Customers suffer a significant lead time to establish new operational environments. In addition, changes to applications that impact the infrastructure have a long lead time.
One of the customers has requested a service-driven approach for a new business application and its associated infrastructure. The hosting organization has agreed to build a PaaS offering.
Which operational tool and process transformation approach is most suitable for the hosting company?

A) Use the existing mature tools and processes that are used for all customers. Manage cloud capacity using the existing process to order storage, network and compute.
B) Design a new service-driven set of tools and processes. Train the IT operations teams to use the new tools. Manage cloud capacity using the existing process to order storage, network and compute.
C) Design a new service-driven set of tools and processes. Train some of the IT operations teams to use the new tools. In advance of service demand, procure appropriate storage, network and compute capability for the cloud.
D) Deploy additional cloud tools alongside existing tooling. Train the IT operations teams to use the new tools. Start to transform operations once the cloud is up and running.
