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

1. The first phase of new ITaaS service introduces the offering to 10% of the engineering organization. The IT organization leverages the management tools used in their traditional data center processes to provide visibility into silos and control of the infrastructure. They also have adapted some ITSM concepts as a framework for their management practices.
During the initial phase of the service deployment, a problem was encountered in one of the VMs. The IT organization is concerned about the extensive amount of time and resources spent determining the cause of the issue.
As a consultant, what should you recommend to prevent these types of service issues?

A) Redesign the service offering with an emphasis on less complexity and interdependence
B) Contract with an outside organization that has extensive experience in resolving cloud service issues
C) Configure the incident management system to identify issues and resolutions
D) Upgrade the management tools to provide holistic visibility into the service dependencies

2. In an effort to grow market share, a financial company has decided to expand their portfolio of web-based services to residential and mobile users. To improve adoption of these services, the software development team was given the requirement to encrypt data in flight without requiring a software footprint on the client.
Which capability best meets their in-flight encryption requirement?

A) SSL VPN
B) IPSEC
C) PGP
D) Cipher-text

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.
Another evaluation point is the completion time for weekly full backups to the cloud service provider. Which would have the most favorable impact on full backup speed?

A) Low IOPS per GB for volumes
B) Target-based deduplication
C) Source-based deduplication
D) Low growth rate for volumes

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

5. A hosting organization operates from two data centers and typically hosts very large customers. The delivery and support of the IT Infrastructure is not service driven. The IT technical delivery functions operate in silos. Customers suffer a significant lead time to establish new operational environments. In addition, changes to applications that impact the infrastructure have a long lead time.
One of the customers has requested a service-driven approach for a new business application and its associated infrastructure. The hosting organization has agreed to build a PaaS offering.
Which operational tool and process transformation approach is most suitable for the hosting company?

A) Design a new service-driven set of tools and processes. Train the IT operations teams to use the new tools. Manage cloud capacity using the existing process to order storage, network and compute.
B) Deploy additional cloud tools alongside existing tooling. Train the IT operations teams to use the new tools. Start to transform operations once the cloud is up and running.
C) Use the existing mature tools and processes that are used for all customers. Manage cloud capacity using the existing process to order storage, network and compute.
D) Design a new service-driven set of tools and processes. Train some of the IT operations teams to use the new tools. In advance of service demand, procure appropriate storage, network and compute capability for the cloud.
