Oracle 1Z0-478 Online Questions & Answers

• Question 31:

  What element first executes the iterative activity and then checks the validity of the condition?

  A. Switch
  B. While
  C. Repeat Until
  D. For Each
  C. Repeat Until

  ---

  If the body of an activity must be performed at least once, use a repeatUntil activity instead of a while activity. The XPath expression condition in the repeatUntil activity is evaluated after the body of the activity completes. The condition is evaluated repeatedly (and the body of the activity processed) until the provided boolean condition is true.

• Question 32:

  You have defined an event. You now want to trigger that event from an existing Mediator component.

  How do you link the event to the Mediator so that the Mediator can raise the event to the Event Delivery Network (EDN)?

  A. Use the SOA Composite Editor to specify the event as a property on the incoming wire into the Mediator component.
  B. Use a text editor to modify the .edl file that defines the event so that the Mediator is identified as a publisher.
  C. Use the SOA Composite Editor to add a raise action to the Mediator's .mplan specification file.
  D. Use Enterprise Manager to associate the Mediator with the appropriate event.
  C. Use the SOA Composite Editor to add a raise action to the Mediator's .mplan specification file.

  Note:

  * What Happens When You Create and Subscribe to a Business Event

  The source code below provides details about the subscribed event of the Oracle Mediator service component.

  Example, Subscribed Event

  xmlns:sub1="/oracle/fodemo/storefront/entities/events/edl/OrderEO" name="sub1:NewOrderSubmitted" consistency="oneAndOnlyOne" runAsRoles="$publisher"/>

• Question 33:

  Which three statements are true about enabling streaming support in adapters?

  A. Enabling streaming allows larger payloads to be read by the adapters.
  B. Enabling streaming improves message throughput and latency.
  C. Enabling streaming leverages features of the scalable DOM in Oracle XML Developer Kit (XDK).
  D. The benefits of enabling streaming are better when payloads are of relatively large.
  A. Enabling streaming allows larger payloads to be read by the adapters.
  C. Enabling streaming leverages features of the scalable DOM in Oracle XML Developer Kit (XDK).
  D. The benefits of enabling streaming are better when payloads are of relatively large.

  Streaming Large Payload

  To enable support to stream payload, you must select the Enable Streaming check box while specifying polling options. When you enable this feature, the payload is streamed to a database instead of getting manipulated in SOA run time as in a memory DOM. You use this feature while handling large payloads. When you select the Enable Streaming check box, a corresponding Boolean property StreamPayload is appended to the ActivationSpec properties defined in the respective .jca file.

• Question 34:

  Identify two fundamental terms in Service Component Architecture (SCA) that are represented visually in the SOA Composite Editor.

  A. Application
  B. Entry point
  C. Component
  D. Wire
  E. External call
  C. Component
  D. Wire

  ---

  C: SOA Composite Editor:

  

  D: You wire (connect) the web service and BPEL process service component. Example Wire Connection:

  

  Note:

  * SOA composite applications consist of the following parts:

  Service binding components Composites Service components Reference binding components Wires

• Question 35:

  Which two configurations provide a certified deployment of multiple SOA domains?

  A. Point all domains to a single SOA Suite schema.
  B. Have separate databases hosting a single SOA Suite schema.
  C. Have a single SOA Suite schema installed on Oracle RAC.
  D. Use Repository Creation Utility (RCU) to create SOA Suite schemas in a single database within unique prefixes.
  A. Point all domains to a single SOA Suite schema.
  D. Use Repository Creation Utility (RCU) to create SOA Suite schemas in a single database within unique prefixes.

  ---

  Note:

  * Oracle SOA Suite components require schemas that must be installed in the Oracle or Microsoft SQL Server database. You create and load these schemas in your database with the Repository Creation Utility (RCU).

• Question 36:

  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.

  Note:

  * 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

• Question 37:

  What does SOA governance complement and influence?

  A. Data center capacity planning
  B. Decisions to use SOAP-based vs. REST-based web services approaches.
  C. Data models that define a shared view of corporate data resources.
  D. IT governance processes and structures
  D. IT governance processes and structures

  ---

  Service-oriented architecture (SOA) has moved beyond hype to widespread acceptance as an IT strategy for delivering business results. Effective SOA governance is essential to achieving measurable, sustainable business value, lowering costs, improving efficiency and increasing visibility. In fact, without it, many SOA initiatives fail. Oracle provides a comprehensive SOA governance solution that unites people, process, and technology to help organizations achieve their SOA objectives at every level of SOA maturity. While early SOA projects may need automation to manage artifacts in the lifecycle, more advanced organizations measure SOA success by how it transforms the business. Governance support is essential to making progress on both technical and business dimensions of SOA.

• Question 38:

  You have modeled a composite that has two BPEL processes: X and Y. The WSDL for Y defines a single portType with a one-way operation. The WSDL for X defines a single portType with a request-response operation. The component property bpel.config.trancation is set to requiresNew for Process X, and the component property bpel.config.oneWayDeliveryPolicy is set to async.persist for process Y. You have wired these components so that Y invokes X.

  What is the result when X throws a remoteFault at runtime, assuming that X has no catch blocks defined within it?

  A. The transaction of X is rolled back, and process Y gets a remoteFault that can be caught and handled.
  B. A Fault policy defined for X for handling the remoteFault is triggered and handles the fault.
  C. The transaction of X is committed, and process gets a Fault back that can be caught and handled.
  D. The transactions of X and Y are both rolled back even If you have fault handlers configured for handling the remote fault in Y.
  B. A Fault policy defined for X for handling the remoteFault is triggered and handles the fault.

  ---

  * Main Process Calls the Subprocess Asynchronously

  If onewayDeliveryPolicy=async.persist (The BPELCallee process runs in a separate thread/transaction.) then If The Subprocess Throws Any Fault... The BPELCaller does not get a response because the message is saved in the delivery service. The BPELCallee transaction is rolled back if the fault is not handled

• Question 39:

  Which statement is true about an if-then rule evaluation?

  A. It can be evaluated more than once.
  B. It is evaluated once and only once.
  C. It must evaluate only native variable types.
  D. It cannot change the assessment for another if-then rule.
  A. It can be evaluated more than once.
