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

Question 1

Refer to Scenario 3.
A US company has deployed web services within a private cloud. They wish to provide additional web services elastically and distribute them around the globe using a public cloud provider.
The web services have a dependency on a database resource in the private cloud. The web services are deployed through a service catalog as a standardized service offering, which includes an intrusion prevention system that periodically polls a central management server for security updates. The IPS management server is located within the private cloud.
The web services collect highly regulated personal health information about consumers who are located around the world.
What would be the best solution for protecting the personal health information collected in the web service?

A. Locate the database in the private cloud. Ensure that the database server complies with FERPA regulations.
B. Store the data on each web server in an encrypted format. Ensure HIPAA compliance across all geographical locations.
C. Store the data on each web server in an encrypted format. Audit for different compliance rules depending on geographical location of the web service.
D. Transmit and store the data in an encrypted format. Locate the database in the private cloud. Ensure that the database server complies with HIPAA regulations.

Question 2

A public cloud service provider wants to improve their IT capabilities in the following areas:
1 - Storage performance trending
2 - More comprehensive element management
3 - Holistic visibility across their storage services
4 - Security and Audit Log Management
5 - Reduce troubleshooting time
Which three areas is ProSphere best suited to address?

A. 1, 2, and 3
B. 3, 4, and 5
C. 2, 3, and 4
D. 1, 3, and 5

Question 3

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

Question 4

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

Question 5

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. ITaaS promotes the rationalization of services currently being offered by IT and offers the services that provide business value through the service catalog.
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. A CMDB can be utilized during the instantiation of the services to improve service levels for the consumers of IT services.
D. ITaaS offers an opportunity to evaluate whether certain IT services should be sourced with a public cloud service provider.
