最新的 Cloud Architect E20-918 免費考試真題:

1. Refer to Scenario 1.
"
An IT department is offering 50 Service Offerings in their service catalog to meet all the application developers' needs. Many of the variants have a very small number of associated instantiations. A "big data" platform is offered and being actively utilized by a team of data scientists.
All services are sourced from within the private cloud. The developers are able to customize the platform's compute, storage, protection and network configuration upon instantiation. They can also provision additional resources after the initial instantiation through an upgrade service within the catalog. Because of the culture of the organization, no chargeback mechanism is implemented.
Within six months, IT experiences these problems:
(a). Developers are complaining of poor and inconsistent performance
(b). Resource utilization has far exceeded expectations
(c). The environment has become very complex
(d). Since the resource pools are shared throughout the organization, IT has been unable to identify usage patterns, making capacity planning very difficult"
What can the IT department do to resolve problem (c)?

A) Offload the "big data" IaaS platform to a public service provider
B) Provide separate resource pools for the application developers and the data scientists and manage the pools separately
C) Standardize on a subset of offerings to meet the needs of most developers and minimize the number of customization options
D) Implement a showback mechanism to influence consumer behavior when choosing specific resources

2. 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 public cloud
C) IaaS deployment in the community cloud
D) IaaS deployment in the private cloud

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) Provide a chargeback bill or showback report
C) Incorporate a service grace period to prevent the actual deletion of the instance
D) Incorporate a retention period for private user data and user PCI data

4. You are working with an independent software vendor to deploy a new SaaS-based application into an organization's private cloud. The application supports REST and SAML binding for authentication. Which cloud single sign-on solution would best fit the needs of this SaaS application?

A) OpenID
B) LDAP
C) OAuth
D) SCIM

5. A software company recently entered into a cooperative development agreement with four global companies to develop control software for a manufacturing business. The software development team will use a development environment that includes ADA compilers and MySQL hosted by the manufacturer.
Which service delivery model should the manufacturing company use?

A) Infrastructure-as-a-Service
B) Platform-as-a-Service
C) Software-as-a-Service
D) Application-as-a-Service
