EMC E20-918 Exam Syllabus Topics:

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

1. An enterprise is beginning its journey to IT-as-a-Service (ITaaS), and has retained a Cloud Architect to assist them. An assessment of their current environment has already been completed and a gap analysis has been done.
What should the Cloud Architect recommend to determine if business activities are aligned with strategic vision?

A) A Balanced Scorecard
B) Right-Sourced Workloads
C) A Controls Matrix
D) ITaaS Organizational Readiness Assessment

2. 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) Standardize on a subset of offerings to meet the needs of most developers and minimize the number of customization options
B) Implement a showback mechanism to influence consumer behavior when choosing specific resources
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

3. 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) Finance
B) SCM
C) Messaging
D) Eng CAD/CAM

4. 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-deploy
B) Time-to-deliver
C) Time-to-live
D) Time-to-value

5. A university is building a private cloud. They plan to offer services to students, faculty, and staff. Each group has access to different levels of sensitive data with different performance characteristics. In addition, the university must comply with FERPA and HIPAA regulations for a small number of services.
What should a cloud architect recommend to the university during the cloud design phase?

A) Implement multi-tenancy trust zones through the service catalog for students, faculty, and staff.
Implement RBAC through the service catalog to protect regulated data.
Create resource pools to support the performance characteristics.
B) Implement multi-tenancy trust zones through the service catalog for students, faculty, and staff.
Implement IT security mechanisms to protect regulated data.
Create resource pools to support the performance characteristics.
C) Implement multi-tenancy trust zones through the service catalog for students, faculty, and staff.
Implement service orchestration to support the performance requirements.
Create resource pools to restrict access to regulated data.
D) Implement multi-tenancy trust zones through the service catalog for regulated data. Implement
RBAC through the service catalog to protect student, faculty and staff data. Create resource pools to support the performance characteristics.
