Exam 12: Designing Distributed and Internet Systems

SOAP is a relatively simple and fast protocol for communicating JSON data between Web service applications and the operating system.

Relative to SOAP and XML,REST and JSON are much simpler to understand,easier for machines to process and generate,and easier for humans to design and implement.

In the ________ model,the user has control over the applications but has limited or no control over the underlying infrastructure.

Decentralized data control is a benefit when using file servers on LANs.

According to the ________ service principle,a service should be usable in many different applications.

A public cloud infrastructure is shared among different companies,with different applications running on the same hardware; as a result,it is impossible for organizations to know where exactly (physically)the data are located,and thus auditing who has access to the data is extremely difficult,if not impossible.

A ________ is the (back-end)portion of the client/server database system running on the server that provides database processing and shared access functions.

Which characteristic is concerned with the stability of the service provider in the long run?

A thin client is a client device designed so that most processing and data storage occur on the ________.

Which characteristic specifies that organizations have to carefully evaluate to what extent the provider will be able to meet current and future business needs in terms of data storage,transaction volumes,and so on?

A(n)________ is the act of creating virtual (rather than physical)versions of a variety of computing capabilities including hardware platforms,operating systems,storage devices,and networks.

According to the ________ service principle,a service should be simple and modular.

JSON is not an alternative to XML and is considered much more complex to transfer and process and much difficult for humans to understand.

________ specifies that service is typically provided using a utility computing model where customers pay only for what they use.

The vast majority of new systems development in organizations focuses on Internet based applications and the Internet can be used for delivering internal organizational systems,business-to-business systems,or business-to-consumer systems.

To allow for most flexibility,users can access cloud resources in a buffet-style fashion on an as-needed basis without the need for lengthy negotiations with the service provider; in many cases,resources in the cloud are accessible by the customer with no need for human interaction with the provider.

________ is a specification for separating style from content when generating XML pages.

________ is a protocol for communicating XML data between Web service applications and the operating system.

A(n)________ cloud is internal to an organization and can help the organization to balance demand and supply of computing resources within the organization.

Which characteristic specifies that an important question to ask from the organization side is which provider can offer the services needed both presently and in the future?
