  D. Use Oracle Event Processing (OEP) to monitor the activities being executed in the BPI l process.
  C. Use a BPEL Process Manager sensor to collect the value and context.

• Question 52:

  You expand a business rule component that a colleague added to the BPEL process. You see an Assign element named Facts_To_Rule_Service.

  Which statement is true bout this Assign element?

  A. It was added automatically based on entries that your colleague made in the dialog box that approved when the business rule component was added to the BPEL model.
  B. Your colleague manually added this Assign element after adding the business rule component to the BPEL Model.
  C. This Assign element was automatically added when your colleague manually added the corresponding Rule_Service_To_Facts assign to the BPEL model.
  D. You can delete this Assign because it was created for documentation purposes only.
  A. It was added automatically based on entries that your colleague made in the dialog box that approved when the business rule component was added to the BPEL model.

  Note:

  * Facts_To_Rule_Service : Assigns the facts to a variable.

• Question 53:

  By using the System Component Architecture (SCA) test framework, you can create tests for which three items?

  A. Reference binding components
  B. Service components like a Mediator
  C. Wires
  D. Invoke activities in a BPL process
  E. Composite sensors
  A. Reference binding components
  B. Service components like a Mediator
  C. Wires

  ---

  The test framework supports testing at the SOA composite application level. In this type of testing, wires (C), service binding components, service components (such as BPEL processes and Oracle Mediator service components) (B), and reference binding components (A) are tested.

• Question 54:

  How is a SAML token used by OWSM for identity propagation?

  A. As each web service in a chain is invoked, OWSM generates a SAML token and inserts it in the WS- Security header of the request message.
  B. A SAML token is generated on invocation of the first web service in a chain and is stored in the Java Authentication and Authorization (JAAS) Subject so it can be used throughout the transaction by subsequent web services.
  C. A SAML token is used to determine the destination address of the next web service in the chain.
  D. The SAML token, embedded in the X.509 certificate or Kerberos ticket, is extracted by OWSM and delivered to the next web service in the chain.
  A. As each web service in a chain is invoked, OWSM generates a SAML token and inserts it in the WS- Security header of the request message.

  Propagating Identities through a Chain of Web Services A web service may invoke another web service which in turn may invoke yet another web service to complete a single transaction (this pattern is known as "chained web services"). Each of the services in the chain may be protected. Instead of checking which service is calling which other service, Oracle WSM allows you to check who the original user invoking the chain of web services is. Oracle WSM policies can be used to propagate the original user's identity across the chained web services. Following successful authentication to the first web service in the chain, Oracle WSM sets the user as a Java Subject used throughout the transaction. When invoking another service, the Oracle WSM client policy picks up the user identity from the Java Subject, generates a SAML token based on the Subject's information, and inserts the SAML token in the WS-Security header of the request message to be sent to the service provider. This allows all the web services in a chain to track the identity of the actual user calling a web service endpoint instead of having the identity of the prior service in the chain calling the first web service to get that information. Note:

  * Security Assertion Markup Language 2.0 (SAML 2.0) is a version of the SAML standard for exchanging authentication and authorization data between security domains. SAML 2.0 is an XML-based protocol that uses security tokens containing assertions to pass information about a principal (usually an end user) between a SAML authority, that is an identity provider, and a SAML consumer, that is a service provider. SAML 2.0 enables web-based authentication and authorization scenarios including cross-domain single sign-on (SSO).

• Question 55:

  You are creating a web service interface to a legacy system that can handle only five concurrent calls. What feature of Oracle Service Bus enables you to define this restriction?

  A. Endpoint management
  B. Throttling
  C. Caching
  D. Choking
  B. Throttling

  ---

  Limiting the Concurrent Number of Requests

  Limiting the concurrent requests for a Business Service cannot be set at design time so you have to use the built-in Oracle Service Bus Administration Console to do it (/sbconsole). Follow these steps to enable it:

  1.

  In Change Center, click Create to start a new Session

  2.

  Select Project Explorer, and navigate to the Business Service you want to limit

  3.

  Select the Operational Settings tab of the View a Business Service page

  4.

  In this tab, under Throttling, select the Enable check box. By enabling throttling you

  1.

  Specify a value for Maximum Concurrency

  2.

  Specify a positive integer value for Throttling Queue to backlog messages that has exceeded the message concurrency limit

  3.

  Specify the maximum time in milliseconds for Message Expiration a message can spend in Throttling Queue

  5.

  Click Update

  6.

  Click Active in Change Center to active the new settings Note:

  * Virtualized Endpoint Management: Ability to specify multiple endpoints for a business service allowing service pooling, load-balancing and failover. Support is also provided for throttling service invocations to protect them from overload.

• Question 56:

  In a BPEL model, what is quickest way to implement a capability to skip rule execution if particular condition holds?

  A. Model a switch activity to conditionally execute the business rule component.
  B. Use a skip condition on the business rule component.
  C. Include an XPath expression in an annotation on the business rule component.
  D. Use a correlation set on the business rule component.
  C. Include an XPath expression in an annotation on the business rule component.

• Question 57:

  You are modeling a conditional branch using a Switch element. You choose not to include an Otherwise branch. What is the result?

  A. A business fault is generated if one of the case branches cannot execute.
  B. A design time error is indicated by JDeveloper.
  C. You need to include fault handler to account for the fact that none of the case branches can execute.
  D. If none of the case branches can execute, control passes to (the next element in the BPEL model.
  D. If none of the case branches can execute, control passes to (the next element in the BPEL model.

  ---

  Note:

  * Conditional branching introduces decision points to control the flow of execution of a BPEL process. You can use a switch activity to produce different actions based on conditional branching. You set up two or more branches, with each branch in the form of an XPath expression. If the expression is true, then the branch is executed. If the expression is false, then the BPEL process moves to the next branch condition, until it either finds a valid branch condition, encounters an otherwise branch, or runs out of branches. If more than one branch condition is true, then BPEL executes the first true branch.

• Question 58:

  Which two statements describe the security policy attachment features of Oracle SOA Suite 11g?

  A. The order in which policies are attached to a subject determines the order in which the policies are executed.
  B. JDeveloper groups the policy that can be attached into the five categories of interceptors.
  C. Only one security polity can be attached to a web service at a time.
  D. In JDeveloper, a security policy can be attached to a web service, but it can be marked as either enabled or disabled.
  A. The order in which policies are attached to a subject determines the order in which the policies are executed.
  D. In JDeveloper, a security policy can be attached to a web service, but it can be marked as either enabled or disabled.

  ---

  Note:

  *

  If necessary, add additional policies.

  You can temporarily disable a policy by deselecting the checkbox to the left of the name of the attached policy. This action does not detach the policy.

  *

  You can attach or detach policies to and from service binding components, service components, and reference binding components in a SOA composite application. Use Oracle JDeveloper to attach policies for testing security in a design-time environment. When your application is ready for deployment to a production environment, you can attach or detach runtime policies in Oracle Enterprise Manager Fusion Middleware Control Console.

• Question 59:

  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.

• Question 60:

  Which expiration and escalation setting can be used to route a task a specified number of levels up a management chain if the assignee does not respond in a given time period?

  A. Never expire
  B. Expire after
  C. Route to manager
  D. Renew after
  E. Escalate after
  F. Management chain
  E. Escalate after

  ---

  Figure, Escalate After Policy
