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

1. Refer to Scenario 1.
"
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.
Within six months, IT experiences these problems:
(a). Developers are complaining of poor and inconsistent performance
(b). Resource utilization has far exceeded expectations
(c). The environment has become very complex
(d). Since the resource pools are shared throughout the organization, IT has been unable to identify usage patterns, making capacity planning very difficult"
What can the IT department do to resolve problem (c)?

A) Implement a showback mechanism to influence consumer behavior when choosing specific resources
B) Standardize on a subset of offerings to meet the needs of most developers and minimize the number of customization options
C) Offload the "big data" IaaS platform to a public service provider
D) Provide separate resource pools for the application developers and the data scientists and manage the pools separately

2. In addition to the service template, what other information do you need to create a service offering?

A) Policies, rules, and orchestration
B) Rules, constraints, and orchestration
C) Rules, constraints, and limits
D) Policies, constraints, and rules

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 measure, gather, analyze, and present the required metrics?
D) Can they control, automate, monitor and manage all elements of the service?

4. An enterprise's IT department is transitioning to ITaaS. The IT department is developing a service management methodology. They are uncertain about how much of the measurement data should be stored, and for how long. One consideration is the trade-off between storage cost and data granularity.
What would you, the cloud architect, recommend as a best practice?

A) Keep only peaks and averages for a longer period of time. This minimizes query time, protection, and recovery issues.
B) Keep more granular data than just peaks and averages. This allows a higher level of monitoring at reasonable cost, given deduplication and compression.
C) Store as much monitoring data as possible given cost constraints. This enables future diagnosis and offers visibility into SLA compliance.
D) Keep all raw data, given that storage costs are relatively low.

5. 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. However, the presenter did not attach a direct financial value to the service catalog.
You are helping to create an initial justification report for the organization. How could you categorize the non-financial benefits of the service catalog?

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