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

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

A) Rules, constraints, and limits
B) Policies, constraints, and rules
C) Rules, constraints, and orchestration
D) Policies, rules, and orchestration

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 all raw data, given that storage costs are relatively low.
B) Keep only peaks and averages for a longer period of time. This minimizes query time, protection, and recovery issues.
C) Store as much monitoring data as possible given cost constraints. This enables future diagnosis and offers visibility into SLA compliance.
D) Keep more granular data than just peaks and averages. This allows a higher level of monitoring at reasonable cost, given deduplication and compression.

3. An IT security team is concerned about the authentication traffic patterns that may be required to integrate the private and public clouds. As a result, IT has elected to federate their active directory using ADFS from the private cloud to the public cloud.
One of the design decisions is whether to use a Layer 2, 3, or 7 firewall / switch mechanism between the public and private clouds. There are trade-offs with each choice.
Which network layer would best address this situation, and why?

A) Layer 2, because it provides the best performance and it is easy to isolate problems.
B) Layer 7, because it allows control at the application layer and is policy driven.
C) Layer 2, because it provides the simplest configuration to manage and it is easy to isolate and troubleshoot problems.
D) Layer 3, because it allows segment isolation while still providing high performance levels.

4. You are reviewing an organization's IT decision making processes in preparation for ITaaS. IT has a history of implementing technologies and solutions that don't meet the needs of the enterprise. What would you recommend to solve this problem?

A) Services should align to IT goals and be implemented through orchestration
B) Services should align to IT goals and be placed in a service catalog
C) Services should align to business objectives and be placed in a service catalog
D) Services should align to business objectives and be implemented through orchestration

5. Which metric measures the time taken to realize benefits from an ITaaS solution?

A) Time-to-value
B) Time-to-deliver
C) Time-to-live
D) Time-to-deploy
