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

1. Refer to Scenario 4.
A construction 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.
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) Low growth rate for volumes
B) Target-based deduplication
C) Low IOPS per GB for volumes
D) Source-based deduplication

2. A large marketing company is in the initial stages of assessing their suitability for ITaaS. You, the
cloud architect, interview the IT personnel and discover the following:
-The company does not maintain a CMDB of their virtual server environment.
-Security software to protect the network from unauthorized external access is inadequate.
-Standardized services offering, self-service provisioning, and consumption-based reporting
capabilities do not exist.
Where would you document your findings?

A) Orchestration gaps report
B) Service gaps report
C) Automation gaps report
D) Technology gaps report

3. The IT group within a manufacturing organization is transforming their manual service offerings into automated service offerings to be available from a service catalog. After reviewing the required KPIs for the service, the service transition project manager asks you if the monitoring tools they currently employ need to be replaced.
What criteria are needed to effectively monitor the required KPIs?

A) Can they provide end-to-end support of the services?
B) Can they integrate with the orchestration engine to provide automation?
C) Can they control, automate, monitor and manage all elements of the service?
D) Can they measure, gather, analyze, and present the required metrics?

4. Refer to the exhibit.

A company is evaluating an ITaaS architecture to provision applications for their various business units. The IT architects consult you for help on the illustrated design.
What is a characteristic of this design?

A) Unbalanced resource utilization
B) Lack of network isolation
C) CPU resource contention
D) Memory resource contention

5. A hosting company has experienced a sudden increase in customer interest and wishes to implement ITaaS. They are now hosting online shopping applications for several retail computer and electronics companies.
Developers in the customer companies have the ability to publish applications and changes to their stores. Shoppers access these stores using a variety of mobile applications and web browsers.
What should be addressed when migrating to ITaaS and implementing a service catalog for the retail and electronic companies?

A) Tenant separation
B) On-demand resource pool creation
C) Integration of multiple hypervisors
D) Support for multiple CMDB systems
