EMC IT-as-a-Service Expert Exam for Cloud Architects Sample Questions:

1. You are reviewing an organization's IT decision making processes in preparation for ITaaS. IT has a history of implementing technologies and solutions that don't meet the needs of the enterprise. What would you recommend to solve this problem?

A) Services should align to business objectives and be implemented through orchestration
B) Services should align to IT goals and be placed in a service catalog
C) Services should align to IT goals and be implemented through orchestration
D) Services should align to business objectives and be placed in a service catalog

2. A hosting company operates from two data centers and typically hosts very large customers. The delivery and support of their IT infrastructure is not service driven. Customers suffer significant lead times to establish new operational environments, or to change existing infrastructure requirements.
A new, highly secure application development environment has been requested by one of the hosting company's customers. The customer has a tight time frame and needs to be able to create a test environment on-demand, within hours. The hosting company has decided to transition to ITaaS to meet the needs of this (and future) clients.
What must be done to achieve this?

A) Allocate capacity in the virtual environment. Maintain an agreed upon set of server gold builds. When needed, start the appropriate number of servers from templates.
B) Utilize a public SaaS provider. Analyze the dependencies that the application may have on infrastructure that is located in the hosting data center.
C) Create an IaaS capability. Agree upon the infrastructure dependencies to meet the application's needs. Use server provisioning tools to build servers when needed.
D) Create a PaaS offering and contract. Automate and orchestrate the creation of the environment on-demand.

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%."
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) Verify that the orchestration engine is configured to trigger the collapse of the underutilized resources
B) Terminate the contract with the CSP and sign a contract with a public provider that better integrates with the solution
C) Contact the CSP representative and renegotiate the terms of service of the contract
D) Contact the CSP representative and negotiate a fixed cost model

4. 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 -
Your second goal is to demonstrate that the CSP solution will be suitable for even the most time consuming backups.
Which application would you select for this test?

A) Email
B) Legal
C) Accounting
D) Development

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