EMC IT-as-a-Service Expert Exam for Cloud Architects Sample Questions:
1. A health care provider is determining the best chargeback model for their organization. Their requirements are:
-Simple to measure -Operational costs should be amortized over a specific time period -Charges should be divided among the lines of business
Which chargeback model satisfies these requirements?
A) Fixed-cost
B) Subscription-by-time
C) Variable-cost
D) Subscription-by-peak-usage
2. An enterprise's IT department is transitioning to ITaaS. The IT department is developing a service management methodology. They are uncertain about how much of the measurement data should be stored, and for how long. One consideration is the trade-off between storage cost and data granularity.
What would you, the cloud architect, recommend as a best practice?
A) Keep more granular data than just peaks and averages. This allows a higher level of monitoring at reasonable cost, given deduplication and compression.
B) Keep all raw data, given that storage costs are relatively low.
C) Store as much monitoring data as possible given cost constraints. This enables future diagnosis and offers visibility into SLA compliance.
D) Keep only peaks and averages for a longer period of time. This minimizes query time, protection, and recovery issues.
3. What is a key design consideration for a service provider to ensure that they can effectively process the termination of a service instance?
A) Archive the associated service data regardless of the user requirements
B) Incorporate a retention period for private user data and user PCI data
C) Automate the de-provisioning process to release resources
D) Incorporate a service grace period to prevent the actual deletion of the instance

A) Unbalanced resource utilization
B) Lack of network isolation
C) CPU resource contention
D) Memory resource contention
5. Refer to Scenario 5.
Refer to the exhibit.
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.
-- Exhibit -
Your second goal is to demonstrate that the CSP solution will be suitable for even the most time consuming backups.
Which application would you select for this test?
A) Accounting
B) Legal
C) Email
D) Development
