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

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

2. An IT group within an organization is transforming their virtualized data center to ITaaS. They plan to implement a chargeback method to appropriately bill the lines of business for the resources consumed.

How would they effectively determine the cost of a service instance?

A) Use the price that is used by a competitive CSP as a baseline. Factor in variable administrative costs, and then divide by the number of planned service instances.
B) Use the cost of the hardware, software, and licensing. Add in growth, then factor in the number of VMs that the hypervisors can support.
C) Use the Windows license cost and growth requirements, then factor in the number of service instances that can be supported.
D) Use the fixed costs and variable costs associated with the service, then factor in the number of service instances that the infrastructure resources can support.

3. A cloud service provider has just delivered a presentation to your organization. During the ROI section of the presentation the vendor described how their predefined service catalog would dramatically reduce service commissioning timing and guarantee a consistent user experience.

A) Time-to-value
B) Time-to-deliver
C) Time-to-live
D) Time-to-deploy

What should be addressed when migrating to ITaaS and implementing a service catalog for the retail and electronic companies?

A) Support for several different CMDB systems
B) On-demand resource pool creation
C) Integration of multiple hypervisors
D) Integration with different authentication systems

5. What is a key design consideration for a service provider to ensure that they can effectively process the termination of a service instance?

B) Archive the associated service data regardless of the user requirements
C) Automate the de-provisioning process to release resources
