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

1. 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.

Your second goal is to demonstrate that the CSP solution will suit even the most demanding application relative to backup needs.
Which application would you select for this test?

A) SCM
B) Finance
C) Eng CAD/CAM
D) Messaging

2. 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.

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 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.
B) 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.
C) 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.
D) 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) A Controls Matrix
C) Right-Sourced Workloads

5. A company has deployed a fully operational, private PaaS service. The service catalog links to an orchestration engine that builds servers automatically.
What is the primary reason the IT security risk team is proposing the use of strong authentication for all service catalog users?

A) Because the catalog is used to define resource pools, an unauthorized user could impact the production systems.
B) Because the catalog is used to define service contracts, an unauthorized user could adjust service level agreements.
C) Because the catalog triggers orchestration actions, an unauthorized user can trigger a denial of service attack.
