EMC IT-as-a-Service Expert Exam for Cloud Architects 認定 E20-918 試験問題:

1. Refer to the exhibit.

A company is evaluating an ITaaS architecture to provision applications for their various business units. The IT architects consult you for help on the illustrated design.
What is a potential risk in the design?

A) CPU resource contention
B) Memory resource contention
C) Unbalanced resource utilization
D) Multi-tenancy

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.
Once the web services were deployed into the public cloud, users started complaining about poor performance. Which solution would most likely improve performance of the web services?

A) Allocate additional virtual network interface cards to each web service to increase bandwidth.
B) Implement a global load balancing service as a front-end for the web services.
C) Select a new internet service provider with a better peering relationship for end users.
D) Re-architect the web service to be loosely coupled.

3. A hosting provider is evaluating potential resource allocation models to use for reserving client resources. Their service offering targets companies that want to run a dedicated private cloud and have mature personnel capable of allocating and managing resources based on their own needs.
Which model would be most suitable?

A) Variable
B) Fixed
C) Pay-as-you-go
D) Guaranteed

4. A company is actively moving business applications to an ITaaS model. The IT department increasingly acts as an adviser, proposing the best fit from either private cloud capability or public cloud suppliers.
The company's finance department is considering their financial applications for cloud as they increasingly need more capacity and better performance at the end of the month, which the current infrastructure cannot deliver. The financial application architecture is three tier (presentation, middleware, and database).
The IT security team has suggested that with appropriate controls the presentation layer could be deployed in a public cloud but the middleware and database layers cannot.
What would be the best approach to enabling service elasticity in this scenario?

A) IaaS deployment in the hybrid cloud
B) IaaS deployment in the community cloud
C) IaaS deployment in the public cloud
D) IaaS deployment in the private cloud

5. Refer to Scenario 7.
"
A web hosting company has been growing steadily over the past year. Their single data center is at maximum capacity for power, space and cooling, and their physical infrastructure is also running at capacity. They are evaluating the feasibility of obtaining another data center in a remote location to enable further growth.
One of the web hosting company's eCommerce customers notifies them that they are launching an enormous holiday sale, beginning in a few weeks. They expect utilization of their virtual server farm to double or triple for the next three to six months. The web hosting company cannot deploy the needed resources in a new data center in time for the sale. They opt to purchase services from a cloud service provider using a pay-as-you-go model.
Over the next two weeks, Layer 2 connectivity is established between the two sites. The web hosting company's IT staff works with the CSP to configure the necessary physical and virtual infrastructure. All traffic to the public cloud is routed through the private data center, across the Layer 2 connection. A local load balancer is deployed in the private data center. Orchestration tools are configured to burst the service into the public cloud automatically when utilization reaches 80%."
During the next month, you are contacted by the billing department. They are unsure why the usage charges for the company have remained constant for several months. You know for certain that their services have been bursting into the public cloud frequently over the past two weeks.
What is the most likely course of action to identify the problem?

A) Confirm that the configuration of the orchestration engine polls the correct data from the CSP
B) Check the details of the service offering and service contract to ensure a pay-as-you-go model is utilized
C) Terminate the contract with the CSP and sign a contract with a public provider that better integrates with the solution
D) Investigate the pricing units in the accounting model to verify that the utility and activity costs are accurate and current
