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

1. An enterprise company has a large, virtualized data center. They are currently auditing their servers to ensure they are in compliance with regulatory requirements.
Why would they choose to deploy VMware vCenter Configuration Manager?

A) It maintains continuous compliance with out-of-the-box templates
B) It ensures that virtual server performance will meet SLAs
C) It maps applications quickly with agentless discovery across physical and virtual machines
D) It automatically scans virtual machines for missing security patches and remediates them

2. 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."
In your analysis, you find that a different hypervisor is being used by the public cloud provider.
As the enterprise elastically provisions resources, what is a possible solution if the hypervisors are different?

A) Create a different service template to deploy in the public cloud.
B) Recalibrate the current service template and deploy it in the public cloud.
C) Shut down services before migrating to the public cloud.
D) Use a second service catalog to deploy the current service template in the public cloud.

3. Refer to the exhibit.

You have been hired to assist with a migration to an ITaaS environment. The company has offices
in Atlanta, Dubai, and London, with 5000, 2000, and 3000 employees, respectively. A data center exists in each location, and most services have been virtualized. Messaging services are provided locally to the user.
You have just performed an assessment of the environment. The results are shown in the exhibit.
The CIO is interested in closing one of the data centers and migrating some or all of the services to a public cloud service provider (CSP). Any services that do not get migrated to the CSP will be hosted at one of the other two data centers. Network latency averages 8 milliseconds between the Atlanta and London offices, and 10 milliseconds between the London and Dubai offices. Traffic between Atlanta and Dubai is routed through London.
The eCommerce application is external facing and is hosted at all three data centers. Atlanta services 50% of the users in North and South America. London services 40% of the users in Europe and Asia. Dubai services 10% of the users in Africa and Australia.
You have tentatively chosen a CSP that is housed in Frankfurt, and would have access to 3 Gb/s of network bandwidth to the facility. The CSP's service levels are as follows:
-RPO: 4 hours -RTO: 1 hour -Availability: 99.995%
Your recommendation is to close the Dubai data center over a one-year time horizon.
What migration strategy would you recommend for the services that are currently hosted in the Dubai data center, and why?

A) Messaging and eCommerce to the public cloud; CSP can support availability and bandwidth requirements for both applications
B) eCommerce to the public cloud; Messaging to London; CSP cannot support the bandwidth requirements for Messaging, and latency will be less from London
C) eCommerce to the public cloud; Messaging to Atlanta; CSP cannot support the bandwidth requirements for Messaging, and latency will be less from Atlanta
D) Messaging to the public cloud; split eCommerce between London and Atlanta; CSP cannot support the availability for eCommerce

4. An enterprise wants to deploy a single sign-on solution to utilize within their private cloud environment. Their developers are experienced with the REST protocol, and they have a large number of interns that are employed May through August every year.
Their primary goal is to build a solution that utilizes the REST protocol. Their secondary goal is to be able to bulk load credentials for the interns into the system each year.
They have asked you to review the offerings from two identity providers. The results of your analysis are shown below:
-Provider A supports OpenID and OAuth -Provider B supports OAuth and SCIM
Which provider would you recommend, and why?

A) B, because it satisfies both the primary and secondary goals
B) B, because it satisfies the primary goal
C) A, because it satisfies the primary goal
D) A, because it satisfies both the primary and secondary goals

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

A) Rules, constraints, and orchestration
B) Policies, rules, and orchestration
