Which one of the following user classification schemes best reflects what function or function performs?

• A.role-based classification
• B.rule-based classification
• C.rank-based classification
• D.attribute-based classification
• E.group-based classification

What does the Java EE Management Specification (JSR 77) provide?

• A.a structured approach to monitor diverse and heterogeneous shared systems
• B.an internet-standard protocol for managing devices on IP networks
• C.a general mechanism for monitoring and managing Java resources
• D.a standard model for managing a J2EE Platform; it describes a standard data model for monitoring and managing the runtime state of any Java EE Web application server and Its resources

Which statement best describes synchronous versus asynchronous communications in a Service Oriented Integration (SOI) architecture?

• A.The SOI architecture should use only asynchronous communication because asynchronous communication provides greater decoupling in the architecture. If a back-end system supports only synchronous communications, the "bridging synchronous and asynchronous communications" integration pattern can be used to convert from synchronous communication to asynchronous communication.
• B.The communication within the SOI architecture should be asynchronous and should follow the publish-and-subscribe integration pattern. The publish-and-subscribe pattern is the most flexible and provides the greatest decoupling and message throughput.
• C.Both synchronous and asynchronous communication should be supported by SOI. Synchronous communication provides an easier programming paradigm. Asynchronous communication provides greater decoupling between the requester and the responder.
• D.The SOA Services in the SOI architecture should use only synchronous communication because SOA Services are inherently synchronous. All communication with back-end system should be asynchronous to decouple the SOA Services from the back-end systems.
• E.The SOI architecture should use only synchronous communication because SOA Services are inherently synchronous. If a back end system supports only asynchronous communications, the "bridging synchronous and asynchronous communications" integration pattern can be used to convert from asynchronous communication to synchronous communication.

Service-Oriented Integration is based on creating a catalogue of SOA Services that expose existing capabilities from back-end systems. Which statement best describes how an SOA Service relates to the existing back-end systems?

• A.An SOA Service should expose the low-level interface of the back-end system to ensure that all back-end system capabilities are fully exposed.
• B.An SOA Service should expose higher-level business capabilities by encapsulating the lower level Interfaces of the back-end systems.
• C.An SOA Service should connect to at least two back-end systems; otherwise the SOA Service is just duplicating the existing interface to the back-end system.
• D.Each SOA Service should expose only one isolated capability of the back-end systems to ensure isolation between SOA Service calls in composite applications.
• E.All access to a back end system should be through a single SOA Service to ensure the back-end system will net become overloaded by service requests.
• F.Each SOA Service exposes the functionality from only a single back-end system to ensure the decoupling of SOA Services.

Which product provides the standard communication protocols (for example, HTTPS) between the Client Tier and the Service Tier as well as Message Security?

• A.Oracle platform Security Services
• B.Oracle HI IP Server
• C.Application Development Framework
• D.Oracle WebCenter
