What does the Java EE Management Specification (JSR 77) provide?
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
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?
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.
The SOA Services can encapsulate multiple layers of theSOI architecture to reducenumber of service calls, which reduces the number of process boundaries being crossed.
The Service-Oriented Integration architecture makes a distinction between technical orchestrations and business processes. Which statement best describes these two concepts?
A business processes is likely to change when the business changes, whereas a technical orchestration is likely to change when back-end systems change.
Which of the following are the implications of the architecture principle, "Asset-centric approach must be applied to engineering processes"?
Assets must be associated with meaningful metadata that can be used to discover and interpret the assets.
When two or more technology perspectives are combined, which statement best describes how the Oracle Reference Architecture (ORA) applies to the combination?
One of the layersin ORAis the Business Services layer that contains the SOA Services. It is these SOA Services that provide the connection between different technology perspectives; therefore the Business Services layer is the interlock between two or more technology perspectives.
A modular approach has been taken to document the Oracle Reference Architecture (ORA). Select the statements that are true for this modular approach?
The ORA library has a document dedicated to each Oracle product suite.
ORA is a single-reference architecture but is documented via different views of the architects-some focused on specific technologies (Technology Perspectives), and some on industry verticals (Industry Perspectives).

Which statement best describes why OWLS is mapped to these three layers in the OSI architecture?
The other Oracle product mapped to the three layers all have OWLS embedded in the product. Thus, OWLS is required for the products mapped into three layers.
Which statements are true with regard to authorization checks being done in the Mediation Layer?
Performing authorization checksin the Mediation Layer provides a centralized approach to securing SOA Services.
Performing authorization checks in the Mediation Layer eliminates the need for role-based authentication.
Which statement best describes the use of point-to-point integrations within a Service-Oriented Integration (SOI) architecture?
Point-to-point integrations should be avoided but are allowed as exceptions when requirements can be met only by point-to-point integration.
Which statement best describes the mapping of User Interaction logical architecture layers to deployment tiers?
The Logical view and Deployment view of the User Interaction architecture do not map effectively from one to the other because other intermediate views are needed.

It is often implemented using transport security protocols such as SSL/TLS.
It is designed to transport sensitive data over unprotected networks.
After data reaches an endpoint, it offers no further protection.
SSL/TLS is used sparingly because it is difficult to set up.
Which of the following are true statements about the benefits of standardizing on a common security framework?
Security requirements no longer need to be specified for eachindividual application; the framework will automatically determine what security needs to be applied.
A common set of security services and information can be used across the organization, promoting Infrastructure reuseand minimizing inconsistencies.
Interoperability amid federation are easier to achieve via the adoption of common security and technology standards.
Which of the following standards states that every reusable asset must contain a minimum of one manifest file and at least one artifact to be considered a valid reusable asset?

A company is building a new customer self-service website. The company has an existing CRM application that contains customer information that needs to be integrated into the self-service website. The CRM application provides a synchronous interface to access the needed customer information. The CRM application takes 5 to 30 seconds to respond to the request for customer information. The requirements for the new customer self-service website is to respond within 3 seconds 90% of the time. What integration pattern would you suggest that the company use to integrate the CRM application into the new customer self-service website?
When customer information from the CRM application is needed, asynchronously fetch the information by using the store-and-forward integration pattern. This approach allows the self-service website to respond quickly to customer requests without waiting for the CRM application. The website can display the fetched customer information when it is available.
