• Question 41:

  A partner needs to access services that are defined in one of your Service Composite Architecture (SCA) applications via a web service interface. Which approach (and accompanying reasoning) describes a loosely coupled and robust solution?

  A. Use Oracle Service Bus to provide an Interface layer over your SCA application. This enables you to hide the locations of your SCA application, perform load-balancing across those endpoints, and provide the ability to define service level agreements to help ensure that you are meeting your contractual obligations to the partner.
  B. Use the Mediator component to provide a web service interface to your SCA application. This arrives you the flexibility of using the industry standard XSLT technology to perform translation and transformations.
  C. Use Oracle Service Bus to provide an interface layer over your SCA application. This enables you to "skin" your SCA application with a web service interface and still provide a robust experience to the partner.
  D. Allow the partner simply to connect directly to the SCA application. This provides the best performance and helps keep the partner happy.

• Question 42:

  Composite A has two versions deployed lo the SOA runtime. Version 2.0 is the default revision, and Version 1.0 is an earlier (but active) revision. Version 2.0 has 100 instances in the Running state also hits 50 instances that are waiting for a callback on a mid-process < receiver> within a BPEL component in the composite. You undeploy Version 2.0. Which statement describes what happens after undeployment completes?

  A. All running Instances and the callbacks are allowed to complete on Version 1.0, but all new requests are served by Version 1.0.
  B. All running Instances are allowed to complete, the callbacks fail after undeployment and all new requests ate served by Version 1.0.
  C. All running instances immediately go stale, including the instances that are awaiting callbacks on the mid process .
  D. All running instances immediately go stale, but the callbacks are processed by Version 1.0.
  C. All running instances immediately go stale, including the instances that are awaiting callbacks on the mid process .

  Note:

  You can undeploy SOA composite applications from Oracle Enterprise Manager Fusion Middleware Control with the Undeploy SOA Composite wizard. Using the Undeploy SOA Composite wizard has the following consequences:

  *

  The instance state of the undeployed composite application is set to stale. The instance state is available in the instance listing, and you can access audit trail and flow trace details.

  *

  If you undeploy the default revision of the SOA composite application (for example, 2.0), the next active, available revision of the application is automatically designated as the new default (for example, 1.0).

  *

  You can no longer configure and monitor this revision of the application.

  *

  You can no longer process instances of this revision of the application.

  *

  The state of currently running instances is changed to stale and no new messages sent to this composite are processed.

  *

  A warning message is displayed at the end of this wizard when you undeploy the default composite revision.

• Question 43:

  What is default transactional behavior for a synchronous request/reply and a one-way synchronous BPEL process?

  A. Required
  B. RequireNew
  C. Mandatory
  D. NotSupported
  E. Supports
  B. RequireNew

  ---

  The default transaction for a synchronous process is requiresNew. That was until version 11.1.1.6. On this last version, you are asking to enter a Transaction parameter when creating a new synchronous bpel process.

• Question 44:

  Composite X invokes an outbound DB adapter to write data to a database table. You have configured JCA at the binding component as follows:

  2 2 You have also modeled a modeled a fault policy to retry the invocation three times in case of remoteFault as follows:

  3 3

  Which result describes what happens when the database that is being accessed by the above binding component goes down?

  A. The invocation is retrieved for a total of two times every two seconds. Fault policy retries are ignored.
  B. The invocation is retried for a total of six times every three seconds.
  C. The invocation is retried for a total of six times every two seconds.
  D. The fault policy retries occur within the JCA retries. So two JCA retries are executed two seconds apart. Within each JCA retry, three fault policy retries are executed three seconds apart.
  E. The JCA retries occur within the fault policy retries. So three fault policy retries are executed three seconds apart. Within each fault policy retry, two JCA retries are executed two seconds apart.
  E. The JCA retries occur within the fault policy retries. So three fault policy retries are executed three seconds apart. Within each fault policy retry, two JCA retries are executed two seconds apart.

  ---

  Note:

  *

  Global retries for any error handling are returned to the BPEL Receive activity instance, for example, or, more generally, to the point at which the transaction started. Such a retry could occur if there was an error such as a temporary database fault. The default retry count is by default indefinite, or specified in the jca.retry.count property.

  *

  Properties you can specify in the composite.xml file include:

  /jca.retry.count

  Specifies the maximum number of retries before rejection. Again, specifying this value is a pre- requisite to specifying the other property values.

  /jca.retry.interval

  Specifies the time interval between retries (measured in seconds.)

  * A remoteFault is also thrown inside an activity. It is thrown because the invocation fails. For example, a SOAP fault is returned by the remote service.

• Question 45:

  Identify the statement that describes an ESB.

  A. An ESB provides a mediation layer between services and consumers.
  B. An ESB facilitates a point-to-point approach to application integration.
  C. An ESB is an execution engine providing Java EE capabilities.
  D. An ESB makes service provider addresses visible to service consumers.
  A. An ESB provides a mediation layer between services and consumers.

  An enterprise service bus (ESB) is a software architecture model used for designing and implementing the interaction and communication between mutually interacting software applications in service-oriented architecture (SOA). As a

  software architecture model for distributed computing it is a specialty variant of the more general client server software architecture model and promotes agility and flexibility with regards to communication and interaction between applications. Its primary use is in enterprise application integration (EAI) of heterogeneous and complex landscapes.

  *

  An enterprise service bus (ESB) is a software architecture for middleware that provides fundamental services for more complex architectures. For example, an ESB incorporates the features required to implement a service-oriented architecture (SOA). In a general sense, an ESB can be thought of as a mechanism that manages access to applications and services (especially legacy versions) to present a single, simple, and consistent interface to end-users via Web- or forms-based client-side front ends.

• Question 46:

  You want to include documentation in the BPEL source code for a business rule component that you are adding to your BPEL model. How would you enter this documentation?

  A. As the value for a BPEL global variable
  B. As a comment attribute on the surrounding scope element
  C. As an annotation on the business rule component
  D. As user documentation on the business rule component
  C. As an annotation on the business rule component

  Note:

  * Example Viewing BPEL Source Code At the bottom of the window, you can use the BPEL Designer and BPEL Source tabs to switch between graphical editing mode (BPEL Designer) and text-editing mode for the source code of the BPEL process (BPEL Source). Two-way editing is enabled; that is, changes you make in one mode are reflected in the other mode.

  

• Question 47:

  Identify four steps that are involved in defining a human task.

  A. Setting the task owner
  B. Specifying outcomes
  C. Specifying parameters
  D. Adding the human task to a BPEL process
  E. Specifying the assignment and routing policy
  F. Defining the task in the Workspace web application
  A. Setting the task owner
  B. Specifying outcomes
  C. Specifying parameters
  E. Specifying the assignment and routing policy

  ---

  The Human Task Editor enables you to define the metadata for the task. The editor enables you to specify human task settings, such as task outcome (B), payload structure, assignment and routing policy (E), expiration and escalation policy,

  notification settings, and so on.

  Incorrect:

  Not D.

  Not F.

• Question 48:

  Identify two correct descriptions of Oracle Web Services Manager (OWSM).

  A. It enables you to externalize web services security from the applications you build.
  B. It manages policies in a distributed policy manager that serves as a single policy enforcement point.
  C. Use security and management events, captured by OWSM agents, are displayed using Oracle BAM.
  D. It supplies predefined security policies that enable declarative security and management definition.
  E. It uses Oracle Event Processing (OEP) to determine when security violations have occurred.
  B. It manages policies in a distributed policy manager that serves as a single policy enforcement point.
  C. Use security and management events, captured by OWSM agents, are displayed using Oracle BAM.

  ---

  Note:

  * Oracle WSM allows companies to (1) centrally define and store declarative policies applied to the multiple web services making up a SOA infrastructure, (2) locally enforce security and management policies through configurable agents, and

  (3) monitor runtime security events such as failed authentication or authorization.

  * Oracle Web Services Manager offers a comprehensive and easy-to-use solution for policy management and security of service infrastructure. It provides visibility and control of the policies through a centralized administration interface offered by Oracle Enterprise Manager.

• Question 49:

  Which statement best describes deploying your SOA application to a cluster?

  A. Manually deploy the application to each managed server in the cluster.
  B. After deployment, restart each managed server in the cluster before the application is available for service.
  C. Use WebLogit Server Administration Console for deployment because you cannot deploy to a cluster from JDeveloper.
  D. Treat your cluster as a single deployment target and let the administration server automatically deploy the application to all managed servers in the cluster.
  D. Treat your cluster as a single deployment target and let the administration server automatically deploy the application to all managed servers in the cluster.

  Oracle SOA Service Infrastructure Cluster-Wide Deployment Composite deployments are stored centrally by the SOA Service Infrastructure in the MDS repository. Each time the SOA Service Infrastructure is started, it synchronizes itself with the MDS repository and SOA store to get the deployment and process state. The deployment coordinator infrastructure orchestrates the notifications for composites deployments and updates. When a new deployment or update takes place, deployment coordinator notifies all members in the cluster. When all members in the cluster confirm that the deployment has succeeded, the master sends a notification to start the composite. If a deployment fails on any one of the nodes, it is rolled back to the rest of the cluster
