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

1. Refer to the exhibit.

A) Between the external network and the internet
B) Between the Service A and Service B
C) Between VM2 and the tenant network
D) Between VM2 and VM4

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) Create an IaaS capability. Agree upon the infrastructure dependencies to meet the application's needs. Use server provisioning tools to build servers when needed.
B) 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.
C) Utilize a public SaaS provider. Analyze the dependencies that the application may have on infrastructure that is located in the hosting data center.
D) Create a PaaS offering and contract. Automate and orchestrate the creation of the environment on-demand.

3. An IT organization is currently 80% virtualized and the CIO is planning for the transition to ITaaS. Senior executives are concerned that IT supports too many services and that many of the services are neither efficient nor necessary.
What argument can the CIO make to address the executives' concerns and convince them that ITaaS is the correct strategic decision?

A) A CMDB can be utilized during the instantiation of the services to improve service levels for the consumers of IT services.
B) ITaaS promotes the concept of on-demand self-service, allowing consumers to use only the services from which they can derive business value.
C) ITaaS offers an opportunity to evaluate whether certain IT services should be sourced with a public cloud service provider.
D) ITaaS promotes the rationalization of services currently being offered by IT and offers the services that provide business value through the service catalog.

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

5. 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 first goal in this proof-of-concept is to demonstrate one quick and successful backup run to the CSP for two different customer applications.
Which two applications would you select, if your desired outcome is backup completion within the shortest possible time?

A) CRM and SCM
B) HR and CRM
C) Messaging and SCM
D) Messaging and CRM
