  The Oracle Service Engineering Framework is an engineering approach for delivering projects within an SOA environment

  The Service Engineering Framework addresses activities at both the program and project scope to consider the requirements of the business outside of the scope of a single project.

  Topics covered at the program scope include:

  *

  SOA Requirements Management - Provides a process for harvesting requirements in a manner that naturally facilitates service identification and discovery.

  *

  Service Identification and Discovery - Establishes the procedures around identifying Service candidates, as well as discovering reuse candidates from the existing Service catalog. Takes the process from identification and discovery, through the justification processes required to determine if an existing Service can be viable for reuse in the proposed manner, or if the proposed Service Candidate should be realized as a shared Service.

  *

  Service Release Planning - Provides the groundwork necessary for planning for project and Service deliveries within an SOA

  Topics covered at the project scope include:

  *

  Service Definition

  *

  Service Design

  *

  Service Implementation - Provides the guidelines for effectively and efficiently developing shared Services.

  *

  Service Testing

  *

  Service Deployment - Defines the guidelines and practices that need to be considered when deploying Services into a shared environment.

  *

  Service OAandM Note: The primary goal of service-oriented integration is to better leverage existing systemwithin the IT environment by applying service-oriented principles. Ultimately, the goal is to enable the assembly of composite applications, with little or no custom coding, that include capabilities sourced from existing systems. Composite applications are applications that pull together data, functionality, and process from multiple existing sources to solve a business problem or create new business value. Service-oriented integration is the mechanism to expose existing sources of data, functionality, and process so that those sources can be readily consumed by a composite application

  Note: Many companies today are deploying enterprise technology strategies (ETS) such as Service- Oriented Architectures (SOA), Business Process Management (BPM), and Cloud Computing, which are designed to make functions, processes, information, and computing resources more available. While these ETSs offer additional benefits and sophistication, they have created a management and visibility gap between the traditionally monitored IT infrastructure resources and the services that contribute to the overall experience encountered by the end user.

• Question 17:

  The Service-Oriented Integration (SOI) architecture can be deployed in a variety of ways. One deployment option is a hierarchical deployment, where each division within the enterprise can deploy the layers of the SOI architecture by using their chosen hardware and software platforms.

  A separate enterprise-wide deployment of the upper layers of the architecture is used to provide cross- divisional integration. Which statements are true for this type of hierarchical deployment of SOI?

  A. Hierarchical deployment of the SOI architecture is the recommended deployment whenever an enterprise has two or more business divisions.
  B. Hierarchical deployment of the SOI architecture is an anti-pattern and should be avoided du-the additional costs associated with supporting multiple hardware and software platforms.
  C. Hierarchical deployment of the SOI architecture is a transitional phase moving toward a peer-peer deployment where the enterprise-wide deployment of the upper layers is eliminated.
  D. Hierarchical deployment of the SOI architecture supports aquestions because each aquestions can be treated as a new division with its own chosen hardware and software platforms.
  E. Because each division is allowed to select the hardware and software platform, industry standards become more important to ensure interoperability between the divisions and the enterprise-wide upper layer.
  F. Because each division is allowed to select the hardware and software platform, platform vendors will have the complete for business, which will reduce the costs of hardware and software, thus reducing the cost of technical deployment versus a shared deployment.
  D. Hierarchical deployment of the SOI architecture supports aquestions because each aquestions can be treated as a new division with its own chosen hardware and software platforms.
  E. Because each division is allowed to select the hardware and software platform, industry standards become more important to ensure interoperability between the divisions and the enterprise-wide upper layer.

  ---

  D: This type of deployment easily supports acquisitions since a new acquisition can be treated as simply another portfolio. E (not F): The primary disadvantage of a hierarchical deployment is the increased cost and complexity of supporting more hardware and software. Adherence to standards to support interoperability is also more important in a hierarchical deployment since the various portfolios may select different products

• Question 18:

  What does ORA Engineering refer to as Round-Trip Engineering?

  A. the ability to effectively perform both forward and reverse engineering to seamlessly transform assets in either direction of the life cycle
  B. the ability to derive artifacts from a previous life-cycle activity
  C. the ability to generate artifacts backwardsinthe life cycle
  D. a continuous improvement process in the SDLC that allows the assets to be produced at various stages of the life cycle with a feedback loop from operations to requirement analysis.
  A. the ability to effectively perform both forward and reverse engineering to seamlessly transform assets in either direction of the life cycle

  ---

  Round-trip engineering is the ability to effectively perform both forward and reverse engineering to seamlessly transform the lifecycle assets. Forward engineering is very useful the first time that code is generated from a model. It saves much

  of the mundane work of keying in classes, attributes, and methods. Reverse engineering is very useful both to transform code into a model when no model previously existed, as well as to resynchronize a model with the code at the end of a

  change.

  Note:

  During an iterative development cycle, once a model has been updated as part of an iteration, another round of forward engineering should allow code to be refreshed with any new classes, methods or attributes that have been added to the

  model. Source code generally contains much more than the model and tools must be very adept at reconstructing the source code that existed prior to the new round of forward engineering. At minimum, the modeling tool should successfully

  support forward engineering the first time and reverse engineering throughout the process.

• Question 20:

  Which of the following statements are true about an end-to-end security strategy?

  A. End-to-end security and point-to-point security are virtually identical strategies proposed by different security vendors.
  B. End-to-end security strives to protect data at rest, even in temporary queues.
  C. End-to-end security often involves some form of message-level protection.
  D. When end-to-end security is enabled. Point-to-point transport-level encryption should be disabledin order to avoid cryptography conflicts between layers.
  E. End to-end security is highly beneficial for distributed computing environments where many point- point connections and intermediaries exist, because it offers seamless data protection.
  B. End-to-end security strives to protect data at rest, even in temporary queues.
  C. End-to-end security often involves some form of message-level protection.
  E. End to-end security is highly beneficial for distributed computing environments where many point- point connections and intermediaries exist, because it offers seamless data protection.

  ---

  B:End to end security is an information-centric perspective of security where information is protected throughout the entire computing environment. That is, from the points where system interactions originate, through all points of integration,

  processing, and persistence. End to end security is often associated with the secure transmission, processing, and storage of data, where at no time are data unprotected Note:

  For a typical web-based application, end to end security generally begins at the client/browser, and ends at the application database and all external dependencies of the application.

  A common challenge in providing end to end security is finding a suitable way to secure data in all states and points along the processing path that does not interfere with any transmission, routing, processing, and storage functions that need

  to occur along the way. Sensitive data will usually need to be decrypted at certain points in order for processing or message routing to occur.
