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

Question 1

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 measure, gather, analyze, and present the required metrics?
C. Can they control, automate, monitor and manage all elements of the service?
D. Can they integrate with the orchestration engine to provide automation?

Question 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.
Which solution would you recommend to best support the web service high availability and minimize service network latency for the consumer?

A. Implement a global load balancing service as a front-end for the web services.
B. Implement a Layer 7 firewall within the public cloud to filter out unnecessary traffic.
C. Use a content delivery network to distribute static web content.
D. Implement a QoS policy that provides a higher priority to http traffic.

Question 3

A marketing company is using a Customer Relationship Management SaaS. The SaaS provider has deployed hardware load balancers to distribute users between application servers. User login states are preserved in the load balancer. Subsequent login requests direct each user to the same application server. If the server is unavailable or too busy, the user cannot log on.
Although the company is very happy with the SaaS cost savings they are unhappy with application availability. To improve application scalability the SaaS provider added new servers to the environment. Users, however, are still experiencing the same problem.
Which service characteristic should the SaaS provider implement to improve the user log-on reliability and scale application performance?

A. Stateless
B. Reusable
C. Abstraction
D. Autonomy

Question 4

Refer to Scenario 5.

An innovative high-end graphics and multimedia 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 first goal in this proof-of-concept is to demonstrate one quick and successful backup run to the CSP for two different customer applications.
Which two applications would you select if your desired outcome is backup completion within the shortest possible time?

A. HR and Library
B. Email and Legal
C. Library and Legal
D. Email and Library

Question 5

A large service provider is designing a solution to protect itself against malicious content, such as viruses in a SOAP attachment, and denial of service attacks.
Which type of firewall is most appropriate for their needs?

A. Linked VPNs
B. XML
C. Reverse proxy servers
D. Federated
