Oracle 1Z0-478 Online Questions & Answers

• Question 71:

  You just added a business rule component to the components section of the SOA Composite Editor canvas. You open your business process for editing and notice that there is no partner link to the decision service for the new rule component.

  What do you do next to make the link appear?

  A. Add an invoke activity to the BPEL model to call the decision service.
  B. Edit the business rule component and specify the If/then rules or the decision table.
  C. Add a business rule component to the BPEL model.
  D. Add a partner link to the BPEL model.
  D. Add a partner link to the BPEL model.

  How to Create a Partner Link To create a partner link:

  1.

  In the SOA Composite Editor, double-click the BPEL process service component. Oracle BPEL Designer is displayed.

  2.

  In the Component Palette, expand BPEL Services.

  3.

  Drag a Partner Link into the appropriate Partner Links swimlane

  

  The Create Partner Link dialog appears.

  4. Complete the fields for this dialog

  Note:

  *

  A partner link enables you to define the external services with which the BPEL process service component is to interact. You can define partner links as services or references (for example, through a JCA adapter) in the SOA Composite Editor or within a BPEL process service component in Oracle BPEL Designer.

  *

  A partner link type characterizes the conversational relationship between two services by defining the roles played by each service in the conversation and specifying the port type provided by each service to receive messages within the conversation.

• Question 72:

  Identify the correct description of a business service.

  A. It is a service that is closely aligned with the goals of the business.
  B. It is metadata about an external service interface that enables Oracle Service Bus to integrate with the external service.
  C. It is programmable entity that enables Oracle Service Bus to connect to a Wide variety of interfaces.
  D. It is a complicated object that often takes days or weeks to implement, but it is highly scalable and reliable after it is complete.
  B. It is metadata about an external service interface that enables Oracle Service Bus to integrate with the external service.

• Question 73:

  Identify three valid BPEL thread pools.

  A. Engine
  B. Callback
  C. Invoke
  D. System
  E. Service
  A. Engine
  C. Invoke
  D. System

  BPEL Threading Model

  When the dispatcher must schedule a dispatch message for execution, it can enqueue the message into a thread pool. Each dispatch set can contain a thread pool (java.util.concurrent.ThreadPoolExecutor). The BPEL thread pool implementation notifies the threads when a message has been enqueued and ensures the appropriate number of threads are instantiated in the pool.

  The following thread properties can be tuned:

  (C)

  Dispatcher Invoke Threads

  (A)Dispatcher Engine Threads

  (D)

  Dispatcher System Threads

  Dispatcher Maximum Request Depth

• Question 74:

  Which statement is true about editing adapter InteractionSpec endpoint properties with Enterprise manager Fusion Middleware Control?

  A. InteractionSpec properties can be added or removed, but they take effect only after the composite is retired and activated.
  B. Adapter endpoint property values can be changed, but they take effect only after the composite is retired and activated.
  C. Adapter endpoints property values can be changed, and they take effect without retiring and activating the composite.
  D. InteractionSpec property values cannot be changed.
  C. Adapter endpoints property values can be changed, and they take effect without retiring and activating the composite.

  ---

  *

  The InteractionSpec or ActivationSpec Properties Properties in this group require the adapter endpoint to be recycled. The values of properties in this group can be changed from the EM console. However, property-dependency constraint validation requires that Oracle JDeveloper be used to make changes (adding or removing) to the composition of these properties.

  *

  The InteractionSpec or ActivationSpec Properties These properties require the adapter endpoint to be recycled. For properties in this group, you can change their values from the EM console. However, to change the composition (add or remove) of these properties, you must use Oracle JDeveloper because of property-dependency constraint validation.

• Question 75:

  Identify two features of Oracle BAM.

  A. Enterprise Manager's monitoring capabilities are central to Oracle BAM's ability to monitor performance indicators.
  B. You can analyze and present Information from activities spanning multiple systems and applications.
  C. Rich browser-based dashboards provide visibility into current values of key performance indicators (KPIs).
  D. There is a built-in trouble ticket system to track assignment and completion of corrective actions.
  A. Enterprise Manager's monitoring capabilities are central to Oracle BAM's ability to monitor performance indicators.
  C. Rich browser-based dashboards provide visibility into current values of key performance indicators (KPIs).

  ---

  Note:

  * Oracle Business Activity Monitoring (Oracle BAM) gives business executives the ability to monitor their business services and processes in the enterprise, to correlate KPIs down to the actual business process themselves, and most important, to change business processes quickly or to take corrective action if the business environment changes.

• Question 76:

  In oracle Service Bus, loose coupling between service provider and service consumer is provided by the __________.

  A. database tables stored in MDS
  B. a proxy service and a business service
  C. a JMS-based queuing service
  D. a Mediator component
  B. a proxy service and a business service

• Question 77:

  Which two features are provided by decision tables?

  A. Sets of input data can be bucketed and reviewed for gaps.
  B. Data sets can be reviewed for conflicts.
  C. Data can be used for only one rule evaluation.
  D. A rule evaluation can be used only to enter new output data.
  A. Sets of input data can be bucketed and reviewed for gaps.
  B. Data sets can be reviewed for conflicts.

  After you create a Decision Table there are operations that you may want to perform on the Decision Table, including the following:

  (A)

  Find and fix gaps in a Decision Table

  (B)

  Finding and resolving conflicts between rules in a Decision Table Compact or split cells in a Decision Table Merge a condition or split a condition in a Decision Table

  A: * Compact the Decision Table

  In this step you compact the rules to merge from eighteen rules to nine rules. This automatically eliminates the rules that are not needed and preserves the no gap, no conflict properties for the Decision Table.

  * The Conditions area in a Decision Table includes one or more condition rows. Each condition row has a condition expression and, for each rule, a condition cell. A condition expression is an expression that you build in Rules Designer. The condition expression is often a fact property or a function result, but it can be any expression that has a type that can be associated with a bucketset.

  B: A Decision Table displays multiple related rules in a single spreadsheet-style view. In Rules Designer a Decision Table presents a collection of related business rules with condition rows, rules, and actions presented in a tabular form that is easy to understand. Business users can compare cells and their values at a glance and can use Decision Table rule analysis features by clicking icons and selecting values in Rules Designer to help identify and correct conflicting or missing cases.

• Question 78:

  View the Exhibit.

  

  There are two groups acting on a task. The group on the left approves line items in the order.

  The group on the right approves the order header. If any actor rejects the order the task completes without routing to any additional actors that have not yet acted on the task.

  Identify the two options that should be selected in the human task definition to achieve this behavior.

  A. Complete parent tasks of early completing subtasks.
  B. Each parallel participant has a local copy of the payload.
  C. Complete task when a participant chooses the reject option.
  D. Enable early completion in parallel subtasks.
  A. Complete parent tasks of early completing subtasks.
  C. Complete task when a participant chooses the reject option.

  ---

  A: Complete parent tasks of early completing subtasks:

  This option is for environments in which you have multiple stages and participants working in parallel.

  Participants perform subtasks in parallel, and one group's rejection or approval of a subtask causes the other group's subtask to also be rejected or approved.

  C: Complete task when a participant chooses:

  A participant in a task can accept or reject it, thus ending the workflow without the task being sent to any other participant. For example, a manager rejects a purchase order, meaning that purchase order is not sent to their manager for review.

  Incorrect:

  Not D: Enable early completion in parallel subtasks

  This option is for environments in which you have multiple stages and participants working in parallel.

  Participants perform subtasks in parallel, and one group's rejection or approval of a subtask does not cause the other group's subtask to also be rejected or approved.
