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.

Your second goal is to demonstrate that the CSP solution will suit even the most demanding application relative to backup needs.
Which application would you select for this test?

A) SCM
B) Messaging
C) Finance
D) Eng CAD/CAM

2. 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.
What can the IT department do to resolve problems (b) and (d)?

A) Provide separate resource pools for the application developers and the data scientists and manage the pools separately
B) Standardize on a subset of offerings to meet the needs of most developers and minimize the number of customization options
C) Decrease the number of IaaS offering variations and customization options
D) Meter usage patterns and implement a showback mechanism to influence consumer behavior when choosing specific resources

3. 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) Explain that the service catalog can be a mechanism for controlling cost by influencing LOB/consumer behavior through showback/chargeback
B) Show how the service catalog and orchestration tools can be viewed in the context of "cost to serve" to provide immediate business value
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

4. An enterprise wants to deploy a single sign-on solution to utilize within their private cloud environment. Their developers are experienced with the REST protocol, and they have a large number of interns that are employed May through August every year.
Their primary goal is to build a solution that utilizes the REST protocol. Their secondary goal is to be able to bulk load credentials for the interns into the system each year.
They have asked you to review the offerings from two identity providers. The results of your analysis are shown below:
-Provider A supports OpenID and OAuth -Provider B supports OAuth and SCIM
Which provider would you recommend, and why?

A) A, because it satisfies the primary goal
B) B, because it satisfies the primary goal
C) B, because it satisfies both the primary and secondary goals
D) A, because it satisfies both the primary and secondary goals
