  The architecture must provide rapid, guided development of the user interface without needlessly exposing the developer to implementation details.

  Reducing the time and resources required to deliver business solutions is required for IT to better support and align with business needs. Low level development is both time consuming and error prone.

• Question 22:

  Why is it necessary to have Integration of Metadata Repository to the Source Code Management (SCM) server?

  A. The SCM needs to access the asset metadata for reporting purposes.
  B. The Metadata Repository links the asset metadata to the asset payload, which may be archived in the SCM.
  C. The Metadata Repository promotes the assets to the SCM.
  D. The Metadata Repository stores the asset metadata in the SCM.
  B. The Metadata Repository links the asset metadata to the asset payload, which may be archived in the SCM.

  ---

  SCM server manages the code base and configuration. It uses file store or database for maintaining the asset payload and to manage the versioning of the assets. Note: 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. It also has integration with other enterprise asset sources like Source Code Management (SCM) tools and file servers. Source Code Management (SCM) is the management of changes to documents, programs, and other information artifacts.

• Question 23:

  The Product Mapping view of the Service-Oriented Integration architecture shows some of the Oracle products mapped onto two or more layers in the architecture. For example, Oracle WebLogic Suite (OWLS) is mapped to the Business Service Layer, the Data Normalization Layer, and the Connectivity Layer. Which statement best describes why OWLS is mapped to these three layers in the OSI architecture?

  A. OWLSis the only product that provides all the capabilities required by the three layers in the OSI architecture.
  B. When OWLSis used to implement the OSI architecture, the three layers need to be combined Into a single architectural layer.
  C. OWLS can be used to host assets delivering the capabilities in any or all of the three layers. Assets hosted on OWLS should still adhere to the layering of the architect.
  D. OWLS plus the other Oracle products that are mapped to the three layers are required to deliver the capabilities for the three layers in the architecture.
  E. 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.
  E. 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.

  ---

  OPSS is incorporated into OWLS which ties the entire Service Tier into the enterprise security architecture. The OWC provides the majority of the capabilities required for a modern user interface. OWC provides some higher-level Connectivity

  capabilities (e.g. connectivity to content management systems, WSRP).

  OWLS provides the base Connectivity (e.g.

  JDBC, JCA) to connect to the Resource Tier.

  Note: Oracle WebLogic Suite (OWLS) - fully implements the latest Java EE standards, provides industry leading reliability and performance, and includes comprehensive management capabilities. OWLS can be used to host the Oracle

  WebCenter products.

• Question 24:

  Which of the following statements are true about point to point security?

  A. It is often implemented using transport security protocols such as SSL/TLS.
  B. It is designed to transport sensitive data over unprotected networks.
  C. After data reaches an endpoint, it offers no further protection.
  D. It can be combined with other forms of security such as perimeter security and defensein depth
  E. SSL/TLS is used sparingly because it is difficult to set up.
  A. It is often implemented using transport security protocols such as SSL/TLS.
  B. It is designed to transport sensitive data over unprotected networks.
  C. After data reaches an endpoint, it offers no further protection.
  E. SSL/TLS is used sparingly because it is difficult to set up.

  ---

  A: The downside to TLS is that it only protects data in transit, or "point-to-point". Once data is received, it is no longer protected.

  B: Point to point security is often used as a

  default or minimal security option in order to protect messages over insecure networks.

  C:A lesser alternative to end to end security is point to point security. This is used to protect messages in transit. It assumes that other means of security are used to protect messages during processing and persistence.

  Generally, less effort is made to protect data behind the corporate firewall. This opens up a number of vulnerabilities and risks to an organization.

  E: SSL/TLS is not so hard to set up. It is popular.

• Question 25:

  The Mediation Layer in the Logical View of the Service-Oriented Integration architecture provides several capabilities. Which of the following are capabilities provided by the Mediation Layer?

  A. enrichment - adding data elements to a data entity to give the entity increased Information
  B. routing - sending the client request to the appropriate provider (s) based on some criteria
  C. message transformation - converting the request message format to a different message form, appropriate for the provider
  D. choreography - defining the messages that flow back and forth between systems that are participating in a business process
  E. protocol mediation - converting a client request from one protocol to a different protocol used by provider
  B. routing - sending the client request to the appropriate provider (s) based on some criteria
  C. message transformation - converting the request message format to a different message form, appropriate for the provider
  E. protocol mediation - converting a client request from one protocol to a different protocol used by provider

  ---

  The Mediation Layer provides loose coupling for the entire architecture. It decouples the layers of the architecture as well as decoupling external users of the layers from the specific layers in the architecture. The key capabilities in this layer include:

  *

  Routing - Routing provides the ability to send the client request to the appropriate provider based on some criteria. The routing may even include sending the client request to multiple providers. This capability facilitates location transparency, versioning, scalability, partitioning, request pipelining, SLA management, etc.

  *

  Protocol Mediation - Protocol mediation is the ability to handle a client request using one protocol (e.g. WS*, JMS, REST) with a provider using a different protocol. This provides protocol decoupling between the provider and the consumer. Message Transformation - Message transformation allows a client request using one message format to be handled by a provider that expects a different message format. This provides message format decoupling between the provider and the consumer.

  *

  Discovery - Discovery is the mechanism by which a client finds a provider of a particular SOA Service. Discovery can occur at design time or runtime.

  *

  Monitoring - Monitoring captures runtime information about the messages flowing through the mediation layer. Since the mediation layer is an intermediary for message traffic, it provides a centralized monitoring capability.

  *

  Policy Enforcement - Policy enforcement provides consistent application of policies (e.g. WS- SecurityPolicy) across all messages flowing through the mediation layer. Since the mediation layer is an intermediary for message traffic, it provides a centralized policy enforcement capability.

• Question 26:

  ---

  C: AJAX is short for "Asynchronous JavaScript And XML", which essentially limits the term to the set of RIA (Rich Internet Application) solutions based on JavaScript.

  D: The Advanced Research Projects Agency created ARPA-net. Internet was developed from ARPA- net.

  Note: A Rich Internet Application (RIA) is a Web application that has many of the characteristics of desktop application software, typically delivered by way of a site-specific browser, a browser plug-in, an independent sandbox, extensive use of JavaScript, or a virtual machine. Adobe Flash, JavaFX, and Microsoft Silverlight are currently the three most common platforms, with desktop browser penetration rates around 96%, 76%, and 66% respectively (as of August 2011).

• Question 27:

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

  A. a general mechanism for monitoring and managing Java resources
  B. an internet-standard protocol for managing devices on IP networks
  C. 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
  D. a structured approach to monitor diverse and heterogeneous shared systems
  C. 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

  ---

  The Java EE Management specification (JSR 77) provides a standard model for managing a J2EE Platform and describes a standard data model for monitoring and managing the runtime state of any Java EE Web application server and its resources.

  Note: The J2EE Management specification includes standard mappings of the model to the Common Information Model (CIM), to an SNMP Management Information Base (MIB), and to the Java object model through a server-resident Enterprise JavaBeans (EJB) component, known as the J2EE Management EJB Component (MEJB). The MEJB provides interoperable remote access to the model from any standard J2EE application.

• Question 28:

  Which of the following statements is true with respect to distributed computing?

  A. Distributed computing must be chosen regardless of the functional and nonfunctional requirements of the business.
  B. Distributed computing must be the architecture of choice when the scalability and availability requirements can be best met by further layering the system.
  C. Distributed computing is best suited for building and running monolithic applications.
  D. The objective of distributed computing is to reduce latency.
  B. Distributed computing must be the architecture of choice when the scalability and availability requirements can be best met by further layering the system.
  C. Distributed computing is best suited for building and running monolithic applications.

  ---

  Distributed computing provides a scalable runtime platform capable of handling many concurrent users by allowing related components to be spread out but at the same time enabling them to work in unison. It allows applications to be broken down into smaller, modular components and be deployed across a distributed infrastructure that leverages the power and flexibility of networked servers. Layered architecture enables separation of concern by defining individual logical layers that can be deployed independently, taking advantage of the distributed infrastructure. Distributed architectures allow selective scalability of the layers that require more capacity to handle the load. This allows efficient use of the hardware and software resources and optimization of performance by fine-tuning the appropriate layer or component. In contrast to some of the other models, distributed computing generally is a CAPEX model where the distributed infrastructure is built in-house for applications to be deployed.

  Note: In distributed computing a program is split up into parts that run simultaneously on multiple computers communicating over a network. Distributed computing is a form of parallel computing, but parallel computing is most commonly used to describe program parts running simultaneously on multiple processors in the same computer. Both types of processing require dividing a program into parts that can run simultaneously, but distributed programs often must deal with heterogeneous environments, network links of varying latencies, and unpredictable failures in the network or the computers.

  Note 2: Distributed computing allows multiple, autonomous computers to work in concert to solve a problem or provide a business solution. Distributed computing is used in the vast majority of modern enterprise business solutions.
