Which statement best describes the reason why the Oracle Reference Architecture defines both a Service Contract and a Usage Agreement?

• A.The Service Contract defines the technical specifics of the SOA Service. The Usage Agreement defines the business aspects of the SOA Service.
• B.Defining both Usage Agreement and Service Contract provides a decoupling between service consumers and service providers.
• C.The Service Contract is the reusable portion of the Usage Agreement that can be shared by other Usage Agreements.
• D.The Usage Agreement is a reusable portion of the Service Contract that can be shared by other Service Contracts.
• E.The Usage Agreement defines how to use the SOA Service. The Service Contract defines the functionality provided by the SOA Service.

Which of the following statements are true?

• B.Traditional "fat client" applications may be deployed across the Internet along with browsers and mobile devices.
• C.The ORA UI architecture may be deployed in a cloud environment by using virtual servers.
• D.When a DMZis used, all components of the architecture are deployed into the demilitarized zone.

Which of the following are the three major tiers of the Logical view of the Oracle Management Reference Architecture?

• A.Managed Target Tier

Because each back-end system is running in a separate process, any integration architecture is required to cross multiple process boundaries. A Service-Oriented Integration (SOI) architecture also introduces SOA Services that run in their own process, thus adding more process boundaries to be crossed. What approaches can be employed to reduce the performance impact of crossing multiple process boundaries?

• A.Service composition should be used to reduce the number of SOA Services that are exposed to the clients
• B.The SOA Services should expose larger-granularity operations to reduce the number of s-calls, which reduces the number of times process boundaries are crossed.
• C.The SOA Services can encapsulate multiple layers of theSOI architecture to reducenumber of service calls, which reduces the number of process boundaries being crossed.
• D.There is nothing that can be done because process boundaries are just part of any integration architecture.
• E.The SOA Services should use XML-based request-and-response messages because XML is a platform- (and hence process-) neutral format.

Which of the following are common uses of an Attribute Service?

• A.to determine which security policy is assigned to a Web Service
• B.to acquire data that are necessary to make access-control decisions
• C.to securely supply personally identifiable information to applications
• D.to maintain metadata pertaining to audit log entries and attestation reports
