  The intent of SOA is to provide common reusable SOA Services that can be leveraged by a variety of consumers. SOA Services are made available to various types of service consumers in order to rationalize the way business functions are

  performed and enterprise data is managed. Its modular architecture approach promotes reuse and business agility, and the use of widely adopted technology standards improves interoperability between business solutions.

  Service consumers consist of various types of business solutions, such as BPM, EDA, MDM, BI.

  SOA Services can also act as service consumers.

  ORA provides a framework to describe how various technology perspectives are related.

  Note:The reference architecture is designed to support an expanding list of technology strategies. It is also important that the various technology perspectives can be easily combined since they are very much complementary.

  ORA embraces service orientation at the core so that services provide a consistent mechanism to expose and combine various technologies and the capabilities. A high-level conceptual model for SOA is used to illustrate how technology

  perspectives consume and provide SOA Services.

• Question 83:

  Which of the following statements best describes the ideal role of an application owner with respect to defining application security?

  A. The application owner must become knowledgeable about security risks, threats, classifications, and policies in order to define security requirements for his or her applications. The more on owner learns about security, the more secure his or her applications will become.
  B. The application owner should hire a security expert to define security requirements for his or herapplications, based on current Industry best practices. Actively implementing the latest trends will best ensure a secure application environment.
  C. The application owner should recommend adherence to common established practices for assessments, classifications, architecture, and policies that have been defined, and are actively maintained, by security experts across the organization. Deviations may be necessary, butapplication owners should strive to be consistent with best practices that have been adopted by the organization.
  D. The application owner, whenever possible, should elect to deploy applications into a public cloud computing environment. Doing so effectivelydelegatesresponsibility and accountability of concerns to another company. The owner doesn't need to be concerned with security as long as the cloud provider has been certified.
  C. The application owner should recommend adherence to common established practices for assessments, classifications, architecture, and policies that have been defined, and are actively maintained, by security experts across the organization. Deviations may be necessary, butapplication owners should strive to be consistent with best practices that have been adopted by the organization.

  ---

  Application ownership can have an effect on application security. Ownership, in this sense, refers to the person, department, or organization that has authority over the security protections and processes that are followed.

  Owners have a role in expressing policy. They may choose to set strict policies and follow best practices and reference architectures. Or, they may choose to be lax on security and/or set their own standards. Ideally, an enterprise-class

  security architecture and processes are developed by pooling industry best practices and ideas, and all applications follow a common strategy without being compromised by ownership issues.

• Question 84:

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

  ---

  Each time a process boundary is crossed there are performance impacts from the network and message marshalling and de-marshalling. This is a primary reason why SOA Services should expose relatively course-grained interfaces (B). This is also a reason why a service implementation might span multiple layers in the architecture .(E)

• Question 85:

  Which of the following is not a part of the Oracle Reference Architecture Monitoring and Management framework?

  A. Integration
  B. Services
  C. Management
  D. User Interaction
  E. Monitoring
  B. Services

  ---

  To define a framework that meets both the management and monitoring requirements and the architecture principles, one might consider the framework to be comprised of four major parts (User Interaction, Management, Monitoring, and Integration) that complement other ORA components (ORA Engineering, ORA Security). The framework utilizes a management repository for storage of all current and historical data and metadata.

• Question 86:

  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?

  A. Use the request-response message exchange pattern to access the synchronous interface provided by the CRM application. The request-response message exchange pattern matches the synchronous interface provided by the CRM application, so this is the simplest and best approach for integration.
  B. 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.
  C. Use the request optional-response message exchange pattern to access the CRM application. If the CRM application responds quickly (for example, in 5 seconds) use that response. If the CRM application does not respond quickly, then the optional response was not returned and processing continues.
  D. When customer information from the CRM application is needed, post a message to a topic queue by using the publish-and-subscribe integration pattern. This approach allows the CRMapplication or any other application subscribing to the topic queue to respond with customer information.
  E. Use the polling integration pattern to find the necessary customer information in the CRM application database. Obviously the data exists in the CRM application database. Obliviously the data exists in the CRM application database, so the slow response from the CRM application can be eliminated by polling directly from the CRM application database.
  B. 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.

  ---

  An asynchronous exchange patternwould be good here. Asynchronous communication can be used when the response time for the source system is too slow to support the timelines of the calling systems. Note: Store-and-forward is a special case of asynchronous communication. In the store-and-forward pattern, the request message is put onto a queue for later retrieval by the target of the request message. Similarly, the response message is put onto a response queue for later retrieval. This is a very common approach used by messaging systems (e.g. MQ Series) to integrate with legacy systems. The architecture must support this integration pattern to facilitate integration with legacy systems and existing messaging systems.

• Question 87:

  What does Lifecycle Management Provisioning refer to?

  A. The process of preparing and equipping a network to allow it to provide (new) services to its users.
  B. Automation of the Installation and configuration of operating systems, infrastructure software, applications, services, virtual servers, and hosts across different platforms, environments, and locations
  C. Demonstration and enforcement of regulatory standards. Industry standards, and internal best practices
  D. A comprehensive management and monitoring solution that helps to effectively manage services from an overview level to theindividual component
  B. Automation of the Installation and configuration of operating systems, infrastructure software, applications, services, virtual servers, and hosts across different platforms, environments, and locations

  ---

  Provisioning deals with automation of the installation and configuration of operating systems, infrastructure software, applications, services, virtual servers, and hosts across different platforms, environments, and locations.

  Note: Lifecycle Management focuses on managing the lifecycle of software, applications, services, virtual servers, and hosts by automating deployment procedures to not only assist in the deployment of software, applications, services, and servers but also the maintenance of these deployments. This makes critical IT operations easy, efficient, and scalable resulting in lower operational risk and cost of ownership. Two key capabilities within lifecycle management is provisioning and patching.

  The primary focus of the Metadata Repository (aka Enterprise Metadata Repository or Enterprise Repository) is design-time, and it usually has no role in the runtime environment of most SOA deployments.

  The metadata repository is primarily a human interface for asset capture and presentment. It has integration with the service registry to promote the service interfaces and with the security framework for repository security like authentication

  and access control.

  Core capabilities of the metadata repository include:

  *

  Asset Management

  *

  Asset Lifecycle Management

  *

  Usage Tracking

  *

  Service Discovery

• Question 90:

  Which of the following are the implications of the architecture principle, "Asset-centric approach must be applied to engineering processes"?

  A. The development Infrastructure must support asset-centric engineering.
  B. Assets must be associated with meaningful metadata that can be used to discover and interpret the assets.
  C. Solutions developed must beintegrated and tested early and often.
  D. Existing assets must be reused to fulfill whole or part functionality when available.
  B. Assets must be associated with meaningful metadata that can be used to discover and interpret the assets.

  The underlying core principle of ORA Engineering is asset sharing and enterprise development through an integrated asset management approach. Most organizations use a Software Configuration Management (SCM) or Version Control System (VCS) for managing the code and configuration assets. These tools are great for managing the versioning of assets produced but they don't maintain the metadata of the assets. Without metadata assets are not organized in context and it is hard to discover them. ORA recommends an asset-centric engineering process, where an Asset Manager is used to address the challenges posed by the traditional approaches. The Asset Manager is typically an enterprise-scoped Metadata Repository working in concert with SCMs and other types of asset repositories.
