EMC E20-918 Exam Syllabus Topics:

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

Question 1

An organization wishes to move toward a full ITaaS implementation. They have a good understanding of Service Oriented Architecture (SOA), but have not established the needed education, teamwork, and discipline to take them to full ITaaS implementation.
As their ITaaS consultant, you need to take them to the next level in the service orientation maturity model. What is the next level?

A. Service Aware
B. Service Neutral
C. Service Capable
D. Service Aligned

Question 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.
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 address problem (a)?

A. Offer additional, larger resource platform options to the developers
B. Divide the "application developer" and "big data" workloads into separate resource pools
C. Standardize on a subset of offerings to meet the needs of most developers and minimize the number of customization options
D. Communicate appropriate SLAs that are realistic given the demand and resources available

Question 3

You are a cloud consultant recently assigned to help an international pharmaceutical manufacturer implement ITaaS. The company has a well-staffed, highly technical IT organization.
There are concerns that implementing ITaaS will be met with resistance, because the IT group may feel that their job security is threatened.
You are seeking an individual within the organization to fill the role of Executive Sponsor for the ITaaS transformation project. Which individual would be the best candidate to fill this role?

A. A senior Finance executive with a familiarity of ITaaS, who is focused on cost savings possible with ITaaS
B. The Vice President of Operations, who is a good communicator and understands ITaaS as it relates to the business
C. The CIO, who has close ties to the IT organization and is focused on emerging technologies for ITaaS
D. A member of the Board of Directors, who holds a high enough position in the organization to drive change

Question 4

Refer to Scenario 7.
"A web hosting company has been growing steadily over the past year. Their single data center is at maximum capacity for power, space and cooling, and their physical infrastructure is also running at capacity. They are evaluating the feasibility of obtaining another data center in a remote location to enable further growth.
One of the web hosting company's eCommerce customers notifies them that they are launching an enormous holiday sale, beginning in a few weeks. They expect utilization of their virtual server farm to double or triple for the next three to six months. The web hosting company cannot deploy the needed resources in a new data center in time for the sale. They opt to purchase services from a cloud service provider using a pay-as-you-go model.
Over the next two weeks, Layer 2 connectivity is established between the two sites. The web hosting company's IT staff works with the CSP to configure the necessary physical and virtual infrastructure. All traffic to the public cloud is routed through the private data center, across the Layer 2 connection. A local load balancer is deployed in the private data center. Orchestration tools are configured to burst the service into the public cloud automatically when utilization reaches 80%."
During the first day of increased usage, the network link between your data center and the CSP fails due to an external problem. You need to design an alternate solution to prevent degradation in the service offering.
Which solution would provide the best performance for the end user?

A. Change the configuration of the local load balancer and retain the IP addresses on the servers in the public cloud
B. Change the configuration of the local load balancer and change the IP addresses for the servers in the public cloud
C. Deploy a global load balancer and retain the IP addresses on the servers in the public cloud
D. Deploy a global load balancer and change the IP addresses for the servers in the public cloud

Question 5

A. Add a web server to the public cloud to ensure proper balance
B. Upgrade the firewall to a newer version to support load balancing and QoS
C. Modify the application using DevOps to be cloud compliant
D. Add a secondary DNS server to the enterprise data center
