Oracle 1Z0-478 Online Questions & Answers

• Question 21:

  Which two tasks cannot be done in the Worklist application?

  A. Update the data in a task parameter.
  B. Register a different user interface for a given type of task.
  C. Set up task routing rules for a vacation period.
  D. Create a new human task.
  E. Escalate a task to your manager.
  B. Register a different user interface for a given type of task.
  D. Create a new human task.

  ---

  Note:

  *

  The Oracle BPEL Worklist Application (Worklist Application) is a Web interface that enables users to act on their assigned human workflow tasks.

  *

  All task interactions--listing tasks, viewing task details, reassigning tasks, performing actions on tasks, setting outcomes, and so on--are initiated from the Task Listing (home) page.

  Incorrect:

  Not C: If there is no predetermined sequence of approvers or if the workflow was designed to permit ad hoc routing, then the task can be routed in an ad hoc fashion. For such tasks, a Route button appears on the Task Details page. From the

  Routing page, you can look up one or more users for routing. When you specify multiple assignees, you can choose whether the list of assignees is for simple (group assignment to all users), sequential, or parallel assignment. In the case of

  parallel assignment, you provide the percentage of votes required for approval.

  Not E:

  

• Question 22:

  Why would you use the Mediator component in a Service Component Architecture (SCA) application Instead of using Oracle Service Bus?

  A. Oracle Service Bus runs out side of a SCA application. Therefore, the Mediator is the only choice for translation and transformation tasks in an SCA application.
  B. The Mediator is much faster than Oracle Service Bus.
  C. The Mediator supports transactions, but Oracle Service Bus does not.
  D. It is always better to use Oracle service Bus Instead of the Mediator.
  A. Oracle Service Bus runs out side of a SCA application. Therefore, the Mediator is the only choice for translation and transformation tasks in an SCA application.

  ---

  Whereas Oracle Service Bus provides service virtualization and protocol transformations for an Oracle SOA Suite application containing multiple composites, Oracle Mediator is an intra- composite mediation component that is deployed within an application.

  Note:

  * Analogous to a load balancer routing HTTP traffic, the Oracle Mediator routes data from service providers to external partners. In addition, it can subscribe to and publish business events. Using Oracle Mediator, you create routing services and rules for them. A routing service is the key component for moving a message across the enterprise service bus from its entry point to its exit point. The rules determine how a message instance processed by the routing service gets to its next destination. Using the rules, Oracle Mediator can perform the following actions:

  Route: Determines the service component (BPEL process, business rule, human task, and mediator) to which to send the messages.

  Validate: Provides support for validating the incoming message payload by using a schematron or an XSD file.

  Filter: If specified in the rules, applies a filter expression that specifies the contents (payload) of a message be analyzed before any service is invoked.

  Transformation: If specified in the rules, transforms document data from one XML schema to another, thus enabling data interchange among applications using different schemas.

• Question 23:

  Which JDeveloper SOA project artifacts have references to the JNDI name of a resource adapter connection factory that is used in the project?

  A. .jca file
  B. .wsdl file
  C. .componentType file
  D. adf-config.xml file
  D. adf-config.xml file

  ---

  Example:

  If the MDS database has a JNDI name, then use the following entries in adf-config.xml:

  class-name="oracle.mds.persistence.stores.db.DBMetadataStore">

• Question 24:

  You are implementing SOA asset lifecycle management in your organization. In the service definition phase, architects and business analysts identify requirements. What should you do with the requirements so they can be tracked through the lifecycle?

  A. Document them in BPEL models.
  B. Add them to the Enterprise Repository.
  C. Add them to the Service Registry.
  D. Use harvesting tools to produce web service implementations.
  E. Produce value chain and strategy map documentation.
  B. Add them to the Enterprise Repository.

  ---

  Note:

  The Oracle Enterprise Repository provides the following value to customers:

  *

  Visibility into all SOA assets and their relationships

  Automatically collects and populates the Oracle Enterprise Repository and o Registry with existing services and other assets through introspection and synchronization with developer tools.

  Provides a flexible and extensible model for categorizing SOA assets.

  o

  Provides visibility of assets that currently exist, are planned, or are in o development to reduce duplication of effort.

  Automatically discovers, maps, and manages new dependencies to o support impact analysis.

  *

  End-to-end governance throughout the lifecycle

  Automates repeatable processes for registration and lifecycle management o through out-of-the-box workflows based on best practices. Provides visibility into policies throughout the lifecycle to promote trust in o

  service quality, performance, and security.

  Communicates architectural standards and tracks architectural o compliance.

  *

  Analytics

  Tracks and reports on reuse throughout the entire service lifecycle, o including development reuse, run time service reuse statistics and data on consumption and compliance through scorecards.

  Collects and communicates vital information on service performance, o quality, and compliance with corporate standards.

  Supports critical decisions with feedback on SOA compliance, o performance, and ROI.

• Question 25:

  Each JCA adapter has a single deployment listed in the WLS Console. Identify two accurate descriptions about managing multiple instances of each adapter in the runtime.

  A. Instance configuration in the SOA Suite deployment plan
  B. JCA tiles for each adapter instance
  C. Adapter connection factories specified in the WLS Console
  D. One entry per adapter instance in the adapters_config.xml file
  A. Instance configuration in the SOA Suite deployment plan
  D. One entry per adapter instance in the adapters_config.xml file

  ---

  * The Oracle Database Adapter is a JCA 1.5 connector, which is deployed to the application server during installation.

  The Oracle Database Adapter consists of multiple instances; each instance represents a connection to a database end point. Different SOA processes may point to the same adapter instance (database), while different service endpoints in a SOA process may point to different adapter instances (databases). Because each adapter instance points to a single database, there is a one-to-one correspondence from adapter instances to application server data sources. Out of the box there is a single Oracle Database Adapter instance named eis/DB/SOADemo, which points to the data source jdbc/SOADataSource.

  The list of adapter instances is stored in a deployment descriptor file, weblogic-ra.xml on Oracle WebLogic Server. (It is inside of DbAdapter.rar, which contains also the Java class files in DBAdapter.jar). Configuring an Oracle Database

  Adapter instance is more about creating the underlying data source:

  getting the correct JDBC driver and connection URL.

• Question 26:

  You want to define a now event to be managed by the Event Delivery Network (EDN). The XSD is in place that defines the element that is to be the basis of the new event. Which step do you perform next?

  A. Create a new event definition in the SOA Composite Editor.
  B. Use an editor to create the event using Event Definition Language (EDL) syntax.
  C. Create the now event definition as you configure the invoke activity that publishes the event in your BPEL process.
  D. Use Enterprise Manager to register the new event to EDN.
  A. Create a new event definition in the SOA Composite Editor.

• Question 27:

  Which two options are allowed in a decision table?

  A. An action modifying an output fact
  B. Asserting an output fact in a decision rule action
  C. Calling a rules function in an assertion
  D. Having rules specifying different actions
  A. An action modifying an output fact
  D. Having rules specifying different actions

  ---

  Note:

  * After you create a Decision Table there are operations that you may want to perform on the Decision Table, including the following: Compact or split cells in a Decision Table Merge a condition or split a condition in a Decision Table Finding and resolving conflicts between rules in a Decision Table Find and fix gaps in a Decision Table

• Question 28:

  Which statement is correct about a JCA common client interface?

  A. The JCA binding component uses the JCA common client Interface APIs to communicate with the resource adapter.
  B. The resource adapter uses the common client interface APIs to communicate with the EIS.
  C. The resource adapter implements the standard MessageListener interface to poll for events from the EIS.
  D. The application server uses the common client interface APIs to commune with the EIS.
  A. The JCA binding component uses the JCA common client Interface APIs to communicate with the resource adapter.

  ---

  Note:

  *

  The Common Client Interface (CCI) is the JCA-recommended client API for all resource adapters.

  *

  A resource adapter is a system-level software driver that enables J2EE components to communicate with a back-end enterprise information system (EIS) through a JCA-compliant application server when a resource adapter for the specific

  EIS is deployed to the server.
