最新的 Cloud Architect E20-918 免費考試真題:

1. 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."
In your analysis, you find that a different hypervisor is being used by the public cloud provider.
As the enterprise elastically provisions resources, what is a possible solution if the hypervisors are different?

A) Recalibrate the current service template and deploy it in the public cloud.
B) Create a different service template to deploy in the public cloud.
C) Shut down services before migrating to the public cloud.
D) Use a second service catalog to deploy the current service template in the public cloud.

2. An enterprise decided to place some sensitive data - intellectual property - in the public cloud and implemented security mechanisms to protect this data.
Recently the public cloud provider's systems had a security breach. The enterprise was not concerned because they felt their data had been completely protected. All of the services housing the data are protected by an IPS application and no alerts were generated by the system.
How did the enterprise protect its data?

A) All data in the public cloud environment was encrypted in-transit only. The encryption keys were
under complete control of the enterprise and were not available to the public provider.
The cloud provider's logs showed that the enterprise's services were neither accessed nor copied.
B) The data was not encrypted but the enterprise maintained a backup of the data in a secure off-
site location.
The cloud provider's logs showed that the enterprise's services were not copied.
C) All data in the public cloud environment was encrypted at-rest and in-transit. Copies of the
encryption keys were secured by the public cloud provider using 1024-bit encryption.
The cloud provider's logs showed that the enterprise's services were neither accessed nor copied.
D) All data in the public cloud environment was encrypted at-rest and in-transit. The encryption
keys were under complete control of the enterprise and were not available to the public provider.
The cloud provider's logs showed that the enterprise's services were copied.

3. An IT organization is currently 80% virtualized and the CIO is planning for the transition to ITaaS. Senior executives are concerned that IT supports too many services and that many of the services are neither efficient nor necessary.
What argument can the CIO make to address the executives' concerns and convince them that ITaaS is the correct strategic decision?

A) ITaaS promotes the concept of on-demand self-service, allowing consumers to use only the services from which they can derive business value.
B) ITaaS promotes the rationalization of services currently being offered by IT and offers the services that provide business value through the service catalog.
C) ITaaS offers an opportunity to evaluate whether certain IT services should be sourced with a public cloud service provider.
D) A CMDB can be utilized during the instantiation of the services to improve service levels for the consumers of IT services.

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

5. A company is deploying a major new business application. The application development has been outsourced to several organizations.
The company has conducted several workshops with all suppliers and the testing team.

What have they achieved?

A) Transition to a DevOps culture
B) Implementation of common collaboration tools
